-HOWTO-RELEASE:
-
-Notes on releasing.
-
-0. Make sure that you have current FSF releases of autoconf, automake,
- and libtool packages installed under a common installation prefix
- and that these tools are in your executable search path prior to
- any other installed versions. Versions delivered with Linux may be
- altered so it is best to install official FSF releases. GNU 'm4'
- 1.4.16 is needed in order to avoid bugs in m4. These packages may
- be downloaded from the following ftp locations:
-

-
- Release builds should only be done on a system with a functioning
- and correctly set system clock and on a filesystem which accurately
- records file update times. Use of GNU make is recommended.
-
-1. Commit any unsaved changes.
-
-2. Create html/vX.X.html. Take ChangeLog entries and html-ify in there.
- Easist thing to do is take html/vX.(X-1).html and use it as a template.
- Add that file to the list of EXTRA_DIST files in the html/Makefile.am.
-
-3. Update html/index.html to refer to this new page as the current release.
-
-4. Increment the release version in configure.ac. Put 'alpha' or
- 'beta' after the version, if applicable. For example:
-
- 4.0.0
- or
- 4.0.0beta7
-
- Version should be updated in two places: in the second argument of the
- AC_INIT macro and in LIBTIFF_xxx_VERSION variables.
-
-5. Update library ELF versioning in configure.ac (LIBTIFF_CURRENT,
- LIBTIFF_REVISION, and LIBTIFF_AGE). These numbers have nothing to
- do with the libtiff release version numbers.
-
- Note that as of libtiff 4.X, proper ELF versioning is used so
- please follow the rules listed in configure.ac. At a bare minimum,
- you should increment LIBTIFF_REVISION for each release so that
- installed library files don't overwrite existing files. If APIs
- have been added, removed, or interface structures have changed,
- then more care is required.
-
-6. Add an entry to Changelog similar to:
-
- * libtiff 4.0.0 released.
-
-7. In the source tree do
-
- ./autogen.sh
-
- This step may be skipped if you have already been using a
- maintainer build with current autoconf, automake, and libtool
- packages. It is only needed when updating tool versions.
-
-8. It is recommended (but not required) to build outside of the source
- tree so that the source tree is kept in a pristine state. This
- also allows sharing the source directory on several networked
- systems. For example:
-
- mkdir libtiff-build
- cd libtiff-build
- /path/to/libtiff/configure --enable-maintainer-mode
-
- otherwise do
-
- ./configure --enable-maintainer-mode
-
-9. In the build tree do
-
- make release
-
- This will update "RELEASE-DATE", "VERSION", and libtiff/tiffvers.h
- in the source tree.
-
-10. In the source tree, verify that the version info in RELEASE-DATE,
- VERSION and libtiff/tiffvers.h is right.
-
-11. In the build tree do
-
- make
- make distcheck
-
- If 'make distcheck' fails, then correct any issues until it
- succeeds.
-
- Two files with names tiff-version.tar.gz and tiff-version.zip will
- be created in the top level build directory.
-
-12. In the source tree do
-
- 'cvs commit'.
-
-13. In the source tree do
-
- cvs tag Release-v4-0-0
-
- (or the appropriate name for the release)
-
-14. Copy release packages from the build tree to the
- ftp.remotesensing.org ftp site.
-
- scp tiff-*.tar.gz tiff-*.zip \
- warmerdam@upload.osgeo.org:/osgeo/download/libtiff
-
-15. Announce to list, tiff@lists.maptools.org
-
-16. Update libtiff page on freshmeat with new version announcement.

-DRAFT TIFF Technical Note #2 17-Mar-95
-============================
-
-This Technical Note describes serious problems that have been found in
-TIFF 6.0's design for embedding JPEG-compressed data in TIFF (Section 22
-of the TIFF 6.0 spec of 3 June 1992). A replacement TIFF/JPEG
-specification is given. Some corrections to Section 21 are also given.
-
-To permit TIFF implementations to continue to read existing files, the 6.0
-JPEG fields and tag values will remain reserved indefinitely. However,
-TIFF writers are strongly discouraged from using the 6.0 JPEG design. It
-is expected that the next full release of the TIFF specification will not
-describe the old design at all, except to note that certain tag numbers
-are reserved. The existing Section 22 will be replaced by the
-specification text given in the second part of this Tech Note.
-
-
-Problems in TIFF 6.0 JPEG
-=========================
-
-Abandoning a published spec is not a step to be taken lightly. This
-section summarizes the reasons that have forced this decision.
-TIFF 6.0's JPEG design suffers from design errors and limitations,
-ambiguities, and unnecessary complexity.
-
-
-Design errors and limitations
------------------------------
-
-The fundamental design error in the existing Section 22 is that JPEG's
-various tables and parameters are broken out as separate fields which the
-TIFF control logic must manage. This is bad software engineering: that
-information should be treated as private to the JPEG codec
-(compressor/decompressor). Worse, the fields themselves are specified
-without sufficient thought for future extension and without regard to
-well-established TIFF conventions. Here are some of the significant
-problems:
-
-* The JPEGxxTable fields do not store the table data directly in the
-IFD/field structure; rather, the fields hold pointers to information
-elsewhere in the file. This requires special-purpose code to be added to
-*every* TIFF-manipulating application, whether it needs to decode JPEG
-image data or not. Even a trivial TIFF editor, for example a program to
-add an ImageDescription field to a TIFF file, must be explicitly aware of
-the internal structure of the JPEG-related tables, or else it will probably
-break the file. Every other auxiliary field in the TIFF spec contains
-data, not pointers, and can be copied or relocated by standard code that
-doesn't know anything about the particular field. This is a crucial
-property of the TIFF format that must not be given up.
-
-* To manipulate these fields, the TIFF control logic is required to know a
-great deal about JPEG details, for example such arcana as how to compute
-the length of a Huffman code table --- the length is not supplied in the
-field structure and can only be found by inspecting the table contents.
-This is again a violation of good software practice. Moreover, it will
-prevent easy adoption of future JPEG extensions that might change these
-low-level details.
-
-* The design neglects the fact that baseline JPEG codecs support only two
-sets of Huffman tables: it specifies a separate table for each color
-component. This implies that encoders must waste space (by storing
-duplicate Huffman tables) or else violate the well-founded TIFF convention
-that prohibits duplicate pointers. Furthermore, baseline decoders must
-test to find out which tables are identical, a waste of time and code
-space.
-
-* The JPEGInterchangeFormat field also violates TIFF's proscription against
-duplicate pointers: the normal strip/tile pointers are expected to point
-into the larger data area pointed to by JPEGInterchangeFormat. All TIFF
-editing applications must be specifically aware of this relationship, since
-they must maintain it or else delete the JPEGInterchangeFormat field. The
-JPEGxxTables fields are also likely to point into the JPEGInterchangeFormat
-area, creating additional pointer relationships that must be maintained.
-
-* The JPEGQTables field is fixed at a byte per table entry; there is no
-way to support 16-bit quantization values. This is a serious impediment
-to extending TIFF to use 12-bit JPEG.
-
-* The 6.0 design cannot support using different quantization tables in
-different strips/tiles of an image (so as to encode some areas at higher
-quality than others). Furthermore, since quantization tables are tied
-one-for-one to color components, the design cannot support table switching
-options that are likely to be added in future JPEG revisions.
-
-
-Ambiguities
------------
-
-Several incompatible interpretations are possible for 6.0's treatment of
-JPEG restart markers:
-
- * It is unclear whether restart markers must be omitted at TIFF segment
- (strip/tile) boundaries, or whether they are optional.
-
- * It is unclear whether the segment size is required to be chosen as
- a multiple of the specified restart interval (if any); perhaps the
- JPEG codec is supposed to be reset at each segment boundary as if
- there were a restart marker there, even if the boundary does not fall
- at a multiple of the nominal restart interval.
-
- * The spec fails to address the question of restart marker numbering:
- do the numbers begin again within each segment, or not?
-
-That last point is particularly nasty. If we make numbering begin again
-within each segment, we give up the ability to impose a TIFF strip/tile
-structure on an existing JPEG datastream with restarts (which was clearly a
-goal of Section 22's authors). But the other choice interferes with random
-access to the image segments: a reader must compute the first restart
-number to be expected within a segment, and must have a way to reset its
-JPEG decoder to expect a nonzero restart number first. This may not even
-be possible with some JPEG chips.
-
-The tile height restriction found on page 104 contradicts Section 15's
-general description of tiles. For an image that is not vertically
-downsampled, page 104 specifies a tile height of one MCU or 8 pixels; but
-Section 15 requires tiles to be a multiple of 16 pixels high.
-
-This Tech Note does not attempt to resolve these ambiguities, so
-implementations that follow the 6.0 design should be aware that
-inter-application compatibility problems are likely to arise.
-
-
-Unnecessary complexity
-----------------------
-
-The 6.0 design creates problems for implementations that need to keep the
-JPEG codec separate from the TIFF control logic --- for example, consider
-using a JPEG chip that was not designed specifically for TIFF. JPEG codecs
-generally want to produce or consume a standard ISO JPEG datastream, not
-just raw compressed data. (If they were to handle raw data, a separate
-out-of-band mechanism would be needed to load tables into the codec.)
-With such a codec, the TIFF control logic must parse JPEG markers emitted
-by the codec to create the TIFF table fields (when writing) or synthesize
-JPEG markers from the TIFF fields to feed the codec (when reading). This
-means that the control logic must know a great deal more about JPEG details
-than we would like. The parsing and reconstruction of the markers also
-represents a fair amount of unnecessary work.
-
-Quite a few implementors have proposed writing "TIFF/JPEG" files in which
-a standard JPEG datastream is simply dumped into the file and pointed to
-by JPEGInterchangeFormat. To avoid parsing the JPEG datastream, they
-suggest not writing the JPEG auxiliary fields (JPEGxxTables etc) nor even
-the basic TIFF strip/tile data pointers. This approach is incompatible
-with implementations that handle the full TIFF 6.0 JPEG design, since they
-will expect to find strip/tile pointers and auxiliary fields. Indeed this
-is arguably not TIFF at all, since *all* TIFF-reading applications expect
-to find strip or tile pointers. A subset implementation that is not
-upward-compatible with the full spec is clearly unacceptable. However,
-the frequency with which this idea has come up makes it clear that
-implementors find the existing Section 22 too complex.
-
-
-Overview of the solution
-========================
-
-To solve these problems, we adopt a new design for embedding
-JPEG-compressed data in TIFF files. The new design uses only complete,
-uninterpreted ISO JPEG datastreams, so it should be much more forgiving of
-extensions to the ISO standard. It should also be far easier to implement
-using unmodified JPEG codecs.
-
-To reduce overhead in multi-segment TIFF files, we allow JPEG overhead
-tables to be stored just once in a JPEGTables auxiliary field. This
-feature does not violate the integrity of the JPEG datastreams, because it
-uses the notions of "tables-only datastreams" and "abbreviated image
-datastreams" as defined by the ISO standard.
-
-To prevent confusion with the old design, the new design is given a new
-Compression tag value, Compression=7. Readers that need to handle
-existing 6.0 JPEG files may read both old and new files, using whatever
-interpretation of the 6.0 spec they did before. Compression tag value 6
-and the field tag numbers defined by 6.0 section 22 will remain reserved
-indefinitely, even though detailed descriptions of them will be dropped
-from future editions of the TIFF specification.
-
-
-Replacement TIFF/JPEG specification
-===================================
-
-[This section of the Tech Note is expected to replace Section 22 in the
-next release of the TIFF specification.]
-
-This section describes TIFF compression scheme 7, a high-performance
-compression method for continuous-tone images.
-
-Introduction
-------------
-
-This TIFF compression method uses the international standard for image
-compression ISO/IEC 10918-1, usually known as "JPEG" (after the original
-name of the standards committee, Joint Photographic Experts Group). JPEG
-is a joint ISO/CCITT standard for compression of continuous-tone images.
-
-The JPEG committee decided that because of the broad scope of the standard,
-no one algorithmic procedure was able to satisfy the requirements of all
-applications. Instead, the JPEG standard became a "toolkit" of multiple
-algorithms and optional capabilities. Individual applications may select
-a subset of the JPEG standard that meets their requirements.
-
-The most important distinction among the JPEG processes is between lossy
-and lossless compression. Lossy compression methods provide high
-compression but allow only approximate reconstruction of the original
-image. JPEG's lossy processes allow the encoder to trade off compressed
-file size against reconstruction fidelity over a wide range. Typically,
-10:1 or more compression of full-color data can be obtained while keeping
-the reconstructed image visually indistinguishable from the original. Much
-higher compression ratios are possible if a low-quality reconstructed image
-is acceptable. Lossless compression provides exact reconstruction of the
-source data, but the achievable compression ratio is much lower than for
-the lossy processes; JPEG's rather simple lossless process typically
-achieves around 2:1 compression of full-color data.
-
-The most widely implemented JPEG subset is the "baseline" JPEG process.
-This provides lossy compression of 8-bit-per-channel data. Optional
-extensions include 12-bit-per-channel data, arithmetic entropy coding for
-better compression, and progressive/hierarchical representations. The
-lossless process is an independent algorithm that has little in
-common with the lossy processes.
-
-It should be noted that the optional arithmetic-coding extension is subject
-to several US and Japanese patents. To avoid patent problems, use of
-arithmetic coding processes in TIFF files intended for inter-application
-interchange is discouraged.
-
-All of the JPEG processes are useful only for "continuous tone" data,
-in which the difference between adjacent pixel values is usually small.
-Low-bit-depth source data is not appropriate for JPEG compression, nor
-are palette-color images good candidates. The JPEG processes work well
-on grayscale and full-color data.
-
-Describing the JPEG compression algorithms in sufficient detail to permit
-implementation would require more space than we have here. Instead, we
-refer the reader to the References section.
-
-
-What data is being compressed?
-------------------------------
-
-In lossy JPEG compression, it is customary to convert color source data
-to YCbCr and then downsample it before JPEG compression. This gives
-2:1 data compression with hardly any visible image degradation, and it
-permits additional space savings within the JPEG compression step proper.
-However, these steps are not considered part of the ISO JPEG standard.
-The ISO standard is "color blind": it accepts data in any color space.
-
-For TIFF purposes, the JPEG compression tag is considered to represent the
-ISO JPEG compression standard only. The ISO standard is applied to the
-same data that would be stored in the TIFF file if no compression were
-used. Therefore, if color conversion or downsampling are used, they must
-be reflected in the regular TIFF fields; these steps are not considered to
-be implicit in the JPEG compression tag value. PhotometricInterpretation
-and related fields shall describe the color space actually stored in the
-file. With the TIFF 6.0 field definitions, downsampling is permissible
-only for YCbCr data, and it must correspond to the YCbCrSubSampling field.
-(Note that the default value for this field is not 1,1; so the default for
-YCbCr is to apply downsampling!) It is likely that future versions of TIFF
-will provide additional PhotometricInterpretation values and a more general
-way of defining subsampling, so as to allow more flexibility in
-JPEG-compressed files. But that issue is not addressed in this Tech Note.
-
-Implementors should note that many popular JPEG codecs
-(compressor/decompressors) provide automatic color conversion and
-downsampling, so that the application may supply full-size RGB data which
-is nonetheless converted to downsampled YCbCr. This is an implementation
-convenience which does not excuse the TIFF control layer from its
-responsibility to know what is really going on. The
-PhotometricInterpretation and subsampling fields written to the file must
-describe what is actually in the file.
-
-A JPEG-compressed TIFF file will typically have PhotometricInterpretation =
-YCbCr and YCbCrSubSampling = [2,1] or [2,2], unless the source data was
-grayscale or CMYK.
-
-
-Basic representation of JPEG-compressed images
-----------------------------------------------
-
-JPEG compression works in either strip-based or tile-based TIFF files.
-Rather than repeating "strip or tile" constantly, we will use the term
-"segment" to mean either a strip or a tile.
-
-When the Compression field has the value 7, each image segment contains
-a complete JPEG datastream which is valid according to the ISO JPEG
-standard (ISO/IEC 10918-1). Any sequential JPEG process can be used,
-including lossless JPEG, but progressive and hierarchical processes are not
-supported. Since JPEG is useful only for continuous-tone images, the
-PhotometricInterpretation of the image shall not be 3 (palette color) nor
-4 (transparency mask). The bit depth of the data is also restricted as
-specified below.
-
-Each image segment in a JPEG-compressed TIFF file shall contain a valid
-JPEG datastream according to the ISO JPEG standard's rules for
-interchange-format or abbreviated-image-format data. The datastream shall
-contain a single JPEG frame storing that segment of the image. The
-required JPEG markers within a segment are:
- SOI (must appear at very beginning of segment)
- SOFn
- SOS (one for each scan, if there is more than one scan)
- EOI (must appear at very end of segment)
-The actual compressed data follows SOS; it may contain RSTn markers if DRI
-is used.
-
-Additional JPEG "tables and miscellaneous" markers may appear between SOI
-and SOFn, between SOFn and SOS, and before each subsequent SOS if there is
-more than one scan. These markers include:
- DQT
- DHT
- DAC (not to appear unless arithmetic coding is used)
- DRI
- APPn (shall be ignored by TIFF readers)
- COM (shall be ignored by TIFF readers)
-DNL markers shall not be used in TIFF files. Readers should abort if any
-other marker type is found, especially the JPEG reserved markers;
-occurrence of such a marker is likely to indicate a JPEG extension.
-
-The tables/miscellaneous markers may appear in any order. Readers are
-cautioned that although the SOFn marker refers to DQT tables, JPEG does not
-require those tables to precede the SOFn, only the SOS. Missing-table
-checks should be made when SOS is reached.
-
-If no JPEGTables field is used, then each image segment shall be a complete
-JPEG interchange datastream. Each segment must define all the tables it
-references. To allow readers to decode segments in any order, no segment
-may rely on tables being carried over from a previous segment.
-
-When a JPEGTables field is used, image segments may omit tables that have
-been specified in the JPEGTables field. Further details appear below.
-
-The SOFn marker shall be of type SOF0 for strict baseline JPEG data, of
-type SOF1 for non-baseline lossy JPEG data, or of type SOF3 for lossless
-JPEG data. (SOF9 or SOF11 would be used for arithmetic coding.) All
-segments of a JPEG-compressed TIFF image shall use the same JPEG
-compression process, in particular the same SOFn type.
-
-The data precision field of the SOFn marker shall agree with the TIFF
-BitsPerSample field. (Note that when PlanarConfiguration=1, this implies
-that all components must have the same BitsPerSample value; when
-PlanarConfiguration=2, different components could have different bit
-depths.) For SOF0 only precision 8 is permitted; for SOF1, precision 8 or
-12 is permitted; for SOF3, precisions 2 to 16 are permitted.
-
-The image dimensions given in the SOFn marker shall agree with the logical
-dimensions of that particular strip or tile. For strip images, the SOFn
-image width shall equal ImageWidth and the height shall equal RowsPerStrip,
-except in the last strip; its SOFn height shall equal the number of rows
-remaining in the ImageLength. (In other words, no padding data is counted
-in the SOFn dimensions.) For tile images, each SOFn shall have width
-TileWidth and height TileHeight; adding and removing any padding needed in
-the edge tiles is the concern of some higher level of the TIFF software.
-(The dimensional rules are slightly different when PlanarConfiguration=2,
-as described below.)
-
-The ISO JPEG standard only permits images up to 65535 pixels in width or
-height, due to 2-byte fields in the SOFn markers. In TIFF, this limits
-the size of an individual JPEG-compressed strip or tile, but the total
-image size can be greater.
-
-The number of components in the JPEG datastream shall equal SamplesPerPixel
-for PlanarConfiguration=1, and shall be 1 for PlanarConfiguration=2. The
-components shall be stored in the same order as they are described at the
-TIFF field level. (This applies both to their order in the SOFn marker,
-and to the order in which they are scanned if multiple JPEG scans are
-used.) The component ID bytes are arbitrary so long as each component
-within an image segment is given a distinct ID. To avoid any possible
-confusion, we require that all segments of a TIFF image use the same ID
-code for a given component.
-
-In PlanarConfiguration 1, the sampling factors given in SOFn markers shall
-agree with the sampling factors defined by the related TIFF fields (or with
-the default values that are specified in the absence of those fields).
-
-When DCT-based JPEG is used in a strip TIFF file, RowsPerStrip is required
-to be a multiple of 8 times the largest vertical sampling factor, i.e., a
-multiple of the height of an interleaved MCU. (For simplicity of
-specification, we require this even if the data is not actually
-interleaved.) For example, if YCbCrSubSampling = [2,2] then RowsPerStrip
-must be a multiple of 16. An exception to this rule is made for
-single-strip images (RowsPerStrip >= ImageLength): the exact value of
-RowsPerStrip is unimportant in that case. This rule ensures that no data
-padding is needed at the bottom of a strip, except perhaps the last strip.
-Any padding required at the right edge of the image, or at the bottom of
-the last strip, is expected to occur internally to the JPEG codec.
-
-When DCT-based JPEG is used in a tiled TIFF file, TileLength is required
-to be a multiple of 8 times the largest vertical sampling factor, i.e.,
-a multiple of the height of an interleaved MCU; and TileWidth is required
-to be a multiple of 8 times the largest horizontal sampling factor, i.e.,
-a multiple of the width of an interleaved MCU. (For simplicity of
-specification, we require this even if the data is not actually
-interleaved.) All edge padding required will therefore occur in the course
-of normal TIFF tile padding; it is not special to JPEG.
-
-Lossless JPEG does not impose these constraints on strip and tile sizes,
-since it is not DCT-based.
-
-Note that within JPEG datastreams, multibyte values appear in the MSB-first
-order specified by the JPEG standard, regardless of the byte ordering of
-the surrounding TIFF file.
-
-
-JPEGTables field
-----------------
-
-The only auxiliary TIFF field added for Compression=7 is the optional
-JPEGTables field. The purpose of JPEGTables is to predefine JPEG
-quantization and/or Huffman tables for subsequent use by JPEG image
-segments. When this is done, these rather bulky tables need not be
-duplicated in each segment, thus saving space and processing time.
-JPEGTables may be used even in a single-segment file, although there is no
-space savings in that case.
-
-JPEGTables:
- Tag = 347 (15B.H)
- Type = UNDEFINED
- N = number of bytes in tables datastream, typically a few hundred
-JPEGTables provides default JPEG quantization and/or Huffman tables which
-are used whenever a segment datastream does not contain its own tables, as
-specified below.
-
-Notice that the JPEGTables field is required to have type code UNDEFINED,
-not type code BYTE. This is to cue readers that expanding individual bytes
-to short or long integers is not appropriate. A TIFF reader will generally
-need to store the field value as an uninterpreted byte sequence until it is
-fed to the JPEG decoder.
-
-Multibyte quantities within the tables follow the ISO JPEG convention of
-MSB-first storage, regardless of the byte ordering of the surrounding TIFF
-file.
-
-When the JPEGTables field is present, it shall contain a valid JPEG
-"abbreviated table specification" datastream. This datastream shall begin
-with SOI and end with EOI. It may contain zero or more JPEG "tables and
-miscellaneous" markers, namely:
- DQT
- DHT
- DAC (not to appear unless arithmetic coding is used)
- DRI
- APPn (shall be ignored by TIFF readers)
- COM (shall be ignored by TIFF readers)
-Since JPEG defines the SOI marker to reset the DAC and DRI state, these two
-markers' values cannot be carried over into any image datastream, and thus
-they are effectively no-ops in the JPEGTables field. To avoid confusion,
-it is recommended that writers not place DAC or DRI markers in JPEGTables.
-However readers must properly skip over them if they appear.
-
-When JPEGTables is present, readers shall load the table specifications
-contained in JPEGTables before processing image segment datastreams.
-Image segments may simply refer to these preloaded tables without defining
-them. An image segment can still define and use its own tables, subject to
-the restrictions below.
-
-An image segment may not redefine any table defined in JPEGTables. (This
-restriction is imposed to allow readers to process image segments in random
-order without having to reload JPEGTables between segments.) Therefore, use
-of JPEGTables divides the available table slots into two groups: "global"
-slots are defined in JPEGTables and may be used but not redefined by
-segments; "local" slots are available for local definition and use in each
-segment. To permit random access, a segment may not reference any local
-tables that it does not itself define.
-
-
-Special considerations for PlanarConfiguration 2
-------------------------------------------------
-
-In PlanarConfiguration 2, each image segment contains data for only one
-color component. To avoid confusing the JPEG codec, we wish the segments
-to look like valid single-channel (i.e., grayscale) JPEG datastreams. This
-means that different rules must be used for the SOFn parameters.
-
-In PlanarConfiguration 2, the dimensions given in the SOFn of a subsampled
-component shall be scaled down by the sampling factors compared to the SOFn
-dimensions that would be used in PlanarConfiguration 1. This is necessary
-to match the actual number of samples stored in that segment, so that the
-JPEG codec doesn't complain about too much or too little data. In strip
-TIFF files the computed dimensions may need to be rounded up to the next
-integer; in tiled files, the restrictions on tile size make this case
-impossible.
-
-Furthermore, all SOFn sampling factors shall be given as 1. (This is
-merely to avoid confusion, since the sampling factors in a single-channel
-JPEG datastream have no real effect.)
-
-Any downsampling will need to happen externally to the JPEG codec, since
-JPEG sampling factors are defined with reference to the full-precision
-component. In PlanarConfiguration 2, the JPEG codec will be working on
-only one component at a time and thus will have no reference component to
-downsample against.
-
-
-Minimum requirements for TIFF/JPEG
-----------------------------------
-
-ISO JPEG is a large and complex standard; most implementations support only
-a subset of it. Here we define a "core" subset of TIFF/JPEG which readers
-must support to claim TIFF/JPEG compatibility. For maximum
-cross-application compatibility, we recommend that writers confine
-themselves to this subset unless there is very good reason to do otherwise.
-
-Use the ISO baseline JPEG process: 8-bit data precision, Huffman coding,
-with no more than 2 DC and 2 AC Huffman tables. Note that this implies
-BitsPerSample = 8 for each component. We recommend deviating from baseline
-JPEG only if 12-bit data precision or lossless coding is required.
-
-Use no subsampling (all JPEG sampling factors = 1) for color spaces other
-than YCbCr. (This is, in fact, required with the TIFF 6.0 field
-definitions, but may not be so in future revisions.) For YCbCr, use one of
-the following choices:
- YCbCrSubSampling field JPEG sampling factors
- 1,1 1h1v, 1h1v, 1h1v
- 2,1 2h1v, 1h1v, 1h1v
- 2,2 (default value) 2h2v, 1h1v, 1h1v
-We recommend that RGB source data be converted to YCbCr for best compression
-results. Other source data colorspaces should probably be left alone.
-Minimal readers need not support JPEG images with colorspaces other than
-YCbCr and grayscale (PhotometricInterpretation = 6 or 1).
-
-A minimal reader also need not support JPEG YCbCr images with nondefault
-values of YCbCrCoefficients or YCbCrPositioning, nor with values of
-ReferenceBlackWhite other than [0,255,128,255,128,255]. (These values
-correspond to the RGB<=>YCbCr conversion specified by JFIF, which is widely
-implemented in JPEG codecs.)
-
-Writers are reminded that a ReferenceBlackWhite field *must* be included
-when PhotometricInterpretation is YCbCr, because the default
-ReferenceBlackWhite values are inappropriate for YCbCr.
-
-If any subsampling is used, PlanarConfiguration=1 is preferred to avoid the
-possibly-confusing requirements of PlanarConfiguration=2. In any case,
-readers are not required to support PlanarConfiguration=2.
-
-If possible, use a single interleaved scan in each image segment. This is
-not legal JPEG if there are more than 4 SamplesPerPixel or if the sampling
-factors are such that more than 10 blocks would be needed per MCU; in that
-case, use a separate scan for each component. (The recommended color
-spaces and sampling factors will not run into that restriction, so a
-minimal reader need not support more than one scan per segment.)
-
-To claim TIFF/JPEG compatibility, readers shall support multiple-strip TIFF
-files and the optional JPEGTables field; it is not acceptable to read only
-single-datastream files. Support for tiled TIFF files is strongly
-recommended but not required.
-
-
-Other recommendations for implementors
---------------------------------------
-
-The TIFF tag Compression=7 guarantees only that the compressed data is
-represented as ISO JPEG datastreams. Since JPEG is a large and evolving
-standard, readers should apply careful error checking to the JPEG markers
-to ensure that the compression process is within their capabilities. In
-particular, to avoid being confused by future extensions to the JPEG
-standard, it is important to abort if unknown marker codes are seen.
-
-The point of requiring that all image segments use the same JPEG process is
-to ensure that a reader need check only one segment to determine whether it
-can handle the image. For example, consider a TIFF reader that has access
-to fast but restricted JPEG hardware, as well as a slower, more general
-software implementation. It is desirable to check only one image segment
-to find out whether the fast hardware can be used. Thus, writers should
-try to ensure that all segments of an image look as much "alike" as
-possible: there should be no variation in scan layout, use of options such
-as DRI, etc. Ideally, segments will be processed identically except
-perhaps for using different local quantization or entropy-coding tables.
-
-Writers should avoid including "noise" JPEG markers (COM and APPn markers).
-Standard TIFF fields provide a better way to transport any non-image data.
-Some JPEG codecs may change behavior if they see an APPn marker they
-think they understand; since the TIFF spec requires these markers to be
-ignored, this behavior is undesirable.
-
-It is possible to convert an interchange-JPEG file (e.g., a JFIF file) to
-TIFF simply by dropping the interchange datastream into a single strip.
-(However, designers are reminded that the TIFF spec discourages huge
-strips; splitting the image is somewhat more work but may give better
-results.) Conversion from TIFF to interchange JPEG is more complex. A
-strip-based TIFF/JPEG file can be converted fairly easily if all strips use
-identical JPEG tables and no RSTn markers: just delete the overhead markers
-and insert RSTn markers between strips. Converting tiled images is harder,
-since the data will usually not be in the right order (unless the tiles are
-only one MCU high). This can still be done losslessly, but it will require
-undoing and redoing the entropy coding so that the DC coefficient
-differences can be updated.
-
-There is no default value for JPEGTables: standard TIFF files must define all
-tables that they reference. For some closed systems in which many files will
-have identical tables, it might make sense to define a default JPEGTables
-value to avoid actually storing the tables. Or even better, invent a
-private field selecting one of N default JPEGTables settings, so as to allow
-for future expansion. Either of these must be regarded as a private
-extension that will render the files unreadable by other applications.

-Changes to Section 21: YCbCr Images
-===================================
-
-[This section of the Tech Note clarifies section 21 to make clear the
-interpretation of image dimensions in a subsampled image. Furthermore,
-the section is changed to allow the original image dimensions not to be
-multiples of the sampling factors. This change is necessary to support use
-of JPEG compression on odd-size images.]
-
-Add the following paragraphs to the Section 21 introduction (p. 89),
-just after the paragraph beginning "When a Class Y image is subsampled":
-
- In a subsampled image, it is understood that all TIFF image
- dimensions are measured in terms of the highest-resolution
- (luminance) component. In particular, ImageWidth, ImageLength,
- RowsPerStrip, TileWidth, TileLength, XResolution, and YResolution
- are measured in luminance samples.
-
- RowsPerStrip, TileWidth, and TileLength are constrained so that
- there are an integral number of samples of each component in a
- complete strip or tile. However, ImageWidth/ImageLength are not
- constrained. If an odd-size image is to be converted to subsampled
- format, the writer should pad the source data to a multiple of the
- sampling factors by replication of the last column and/or row, then
- downsample. The number of luminance samples actually stored in the
- file will be a multiple of the sampling factors. Conversely,
- readers must ignore any extra data (outside the specified image
- dimensions) after upsampling.
-
- When PlanarConfiguration=2, each strip or tile covers the same
- image area despite subsampling; that is, the total number of strips
- or tiles in the image is the same for each component. Therefore
- strips or tiles of the subsampled components contain fewer samples
- than strips or tiles of the luminance component.
-
- If there are extra samples per pixel (see field ExtraSamples),
- these data channels have the same number of samples as the
- luminance component.
-
-Rewrite the YCbCrSubSampling field description (pp 91-92) as follows
-(largely to eliminate possibly-misleading references to
-ImageWidth/ImageLength of the subsampled components):
-
- (first paragraph unchanged)
-
- The two elements of this field are defined as follows:
-
- Short 0: ChromaSubsampleHoriz:
-
- 1 = there are equal numbers of luma and chroma samples horizontally.
-
- 2 = there are twice as many luma samples as chroma samples
- horizontally.
-
- 4 = there are four times as many luma samples as chroma samples
- horizontally.
-
- Short 1: ChromaSubsampleVert:
-
- 1 = there are equal numbers of luma and chroma samples vertically.
-
- 2 = there are twice as many luma samples as chroma samples
- vertically.
-
- 4 = there are four times as many luma samples as chroma samples
- vertically.
-
- ChromaSubsampleVert shall always be less than or equal to
- ChromaSubsampleHoriz. Note that Cb and Cr have the same sampling
- ratios.
-
- In a strip TIFF file, RowsPerStrip is required to be an integer
- multiple of ChromaSubSampleVert (unless RowsPerStrip >=
- ImageLength, in which case its exact value is unimportant).
- If ImageWidth and ImageLength are not multiples of
- ChromaSubsampleHoriz and ChromaSubsampleVert respectively, then the
- source data shall be padded to the next integer multiple of these
- values before downsampling.
-
- In a tiled TIFF file, TileWidth must be an integer multiple of
- ChromaSubsampleHoriz and TileLength must be an integer multiple of
- ChromaSubsampleVert. Padding will occur to tile boundaries.
-
- The default values of this field are [ 2,2 ]. Thus, YCbCr data is
- downsampled by default!

-Defining New TIFF Tags
-</H1>
-
-Libtiff has built-in knowledge of all the standard TIFF tags, as
-well as extentions. The following describes how to add knowledge of
-new tags as builtins to libtiff, or how to application specific tags can
-be used by applications without modifying libtiff.
-<p>
-
-<h2>TIFFFieldInfo</h2>
-
-How libtiff manages specific tags is primarily controlled by the
-definition for that tag value stored internally as a TIFFFieldInfo structure.
-This structure looks like this:
-<p>
-
-<pre>
-typedef struct {
- ttag_t field_tag; /* field's tag */
- short field_readcount; /* read count/TIFF_VARIABLE/TIFF_SPP */
- short field_writecount; /* write count/TIFF_VARIABLE */
- TIFFDataType field_type; /* type of associated data */
- unsigned short field_bit; /* bit in fieldsset bit vector */
- unsigned char field_oktochange;/* if true, can change while writing */
- unsigned char field_passcount;/* if true, pass dir count on set */
- char *field_name; /* ASCII name */
-} TIFFFieldInfo;
-</pre>
-
-<ul>
-<li> <b>field_tag</b>: the tag number. For instance 277 for the
-SamplesPerPixel tag. Builtin tags will generally have a #define in
-tiff.h for each known tag. <p>
-
-<li> <b>field_readcount</b>: The number of values which should be read.
-The special value TIFF_VARIABLE (-1) indicates that a variable number of
-values may be read. The special value TIFFTAG_SPP (-2) indicates that there
-should be one value for each sample as defined by TIFFTAG_SAMPLESPERPIXEL.
-The special value TIFF_VARIABLE2 (-3) is presumably similar to TIFF_VARIABLE
-though I am not sure what the distinction in behaviour is. This field
-is TIFF_VARIABLE for variable length ascii fields.<p>
-
-<li> <b>field_writecount</b>: The number of values which should be written.
-Generally the same as field_readcount. A few built-in exceptions exist, but
-I haven't analysed why they differ. <p>
-
-<li> <b>field_type</b>: Type of the field. One of TIFF_BYTE, TIFF_ASCII,
-TIFF_SHORT, TIFF_LONG, TIFF_RATIONAL, TIFF_SBYTE, TIFF_UNDEFINED,
-TIFF_SSHORT, TIFF_SLONG, TIFF_SRATIONAL, TIFF_FLOAT, TIFF_DOUBLE or
-TIFF_IFD. Note that some fields can support more than one type (for
-instance short and long). These fields should have multiple TIFFFieldInfos.
-<p>
-
-<li> <b>field_bit</b>: Built-in tags stored in special fields in the
-TIFF structure have assigned field numbers to distinguish them (ie.
-FIELD_SAMPLESPERPIXEL). New tags should generally just use
-FIELD_CUSTOM indicating they are stored in the generic tag list.<p>
-
-<li> <b>field_oktochange</b>: TRUE if it is OK to change this tag value
-while an image is being written. FALSE for stuff that must be set once
-and then left unchanged (like ImageWidth, or PhotometricInterpretation for
-instance).<p>
-
-<li> <b>field_passcount</b>: If TRUE, then the count value must be passed
-in TIFFSetField(), and TIFFGetField(), otherwise the count is not required.
-This should generally be TRUE for non-ascii variable count tags unless
-the count is implicit (such as with the colormap).<p>
-
-<li> <b>field_name</b>: A name for the tag. Normally mixed case (studly caps)
-like "StripByteCounts" and relatively short. <p>
-
-</ul>
-
-A TIFFFieldInfo definition exists for each built-in tag in the tif_dirinfo.c
-file. Some tags which support multiple data types have more than one
-definition, one per data type supported. <p>
-
-Various functions exist for getting the internal TIFFFieldInfo definitions,
-including _TIFFFindFieldInfo(), and _TIFFFindFieldInfoByName(). See
-tif_dirinfo.c for details. There must be some mechanism to get the whole
-list, though I don't see it off hand.<p>
-
-<h2>Default Tag Auto-registration</h2>
-
-In libtiff 3.6.0 a new mechanism was introduced allowing libtiff to
-read unrecognised tags automatically. When an unknown tags is encountered,
-it is automatically internally defined with a default name and a type
-derived from the tag value in the file. Applications only need to predefine
-application specific tags if they need to be able to set them in a file, or
-if particular calling conventions are desired for TIFFSetField() and
-TIFFGetField().<p>
-
-When tags are autodefined like this the <b>field_readcount</b> and
-<b>field_writecount</b> values are always TIFF_VARIABLE. The
-<b>field_passcount</b> is always TRUE, and the <b>field_bit</b> is
-FIELD_CUSTOM. The field name will be "Tag %d" where the %d is the tag
-number.<p>
-
-<h2>Defining Application Tags</h2>
-
-For various reasons, it is common for applications to want to define
-their own tags to store information outside the core TIFF specification.
-This is done by calling TIFFMergeFieldInfo() with one or more TIFFFieldInfos.
-<p>
-
-The libgeotiff library provides geospatial information extentions within
-a TIFF file. First, a set of TIFFFieldInfo's is prepared with information
-on the new tags:<p>
-
-<pre>
-static const TIFFFieldInfo xtiffFieldInfo[] = {
-
- /* XXX Insert Your tags here */
- { TIFFTAG_GEOPIXELSCALE, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
- TRUE, TRUE, "GeoPixelScale" },
- { TIFFTAG_GEOTRANSMATRIX, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
- TRUE, TRUE, "GeoTransformationMatrix" },
- { TIFFTAG_GEOTIEPOINTS, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
- TRUE, TRUE, "GeoTiePoints" },
- { TIFFTAG_GEOKEYDIRECTORY, -1,-1, TIFF_SHORT, FIELD_CUSTOM,
- TRUE, TRUE, "GeoKeyDirectory" },
- { TIFFTAG_GEODOUBLEPARAMS, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
- TRUE, TRUE, "GeoDoubleParams" },
- { TIFFTAG_GEOASCIIPARAMS, -1,-1, TIFF_ASCII, FIELD_CUSTOM,
- TRUE, FALSE, "GeoASCIIParams" }
-};
-</pre>
-
-In order to define the tags, we call TIFFMergeFieldInfo() on the
-desired TIFF handle with the list of TIFFFieldInfos.<p>
-
-<pre>
-#define N(a) (sizeof (a) / sizeof (a[0]))
-
- /* Install the extended Tag field info */
- TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
-</pre>
-
-The tags need to be defined for each TIFF file opened - and when reading
-they should be defined before the tags of the file are read, yet a valid
-TIFF * is needed to merge the tags against. In order to get them
-registered at the appropriate part of the setup process, it is necessary
-to register our merge function as an extender callback with libtiff.
-This is done with TIFFSetTagExtender(). We also keep track of the
-previous tag extender (if any) so that we can call it from our extender
-allowing a chain of customizations to take effect. <P>
-
-<pre>
-static TIFFExtendProc _ParentExtender = NULL;
-
-static
-void _XTIFFInitialize(void)
-{
- static int first_time=1;
-
- if (! first_time) return; /* Been there. Done that. */
- first_time = 0;
-
- /* Grab the inherited method and install */
- _ParentExtender = TIFFSetTagExtender(_XTIFFDefaultDirectory);
-}
-</pre>
-
-The extender callback is looks like this. It merges in our new fields
-and then calls the next extender if there is one in effect.<p>
-
-<pre>
-static void
-_XTIFFDefaultDirectory(TIFF *tif)
-{
- /* Install the extended Tag field info */
- TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
-
- /* Since an XTIFF client module may have overridden
- * the default directory method, we call it now to
- * allow it to set up the rest of its own methods.
- */
-
- if (_ParentExtender)
- (*_ParentExtender)(tif);
-}
-</pre>
-
-The above approach ensures that our new definitions are used when reading
-or writing any TIFF file. However, since on reading we already have
-default definitions for tags, it is usually not critical to pre-define them.
-If tag definitions are only required for writing custom tags, you can just
-call TIFFMergeFieldInfo() before setting new tags. The whole extender
-architecture can then be avoided.<p>
-
-<A NAME=AddingTags><P><H2>Adding New Builtin Tags</H2></A>
-
-A similar approach is taken to the above. However, the TIFFFieldInfo
-should be added to the tiffFieldInfo[] list in tif_dirinfo.c. Ensure that
-new tags are added in sorted order by the tag number.<p>
-
-Normally new built-in tags should be defined with FIELD_CUSTOM; however, if
-it is desirable for the tag value to have it's own field in the TIFFDirectory
-structure, then you will need to #define a new FIELD_ value for it, and
-add appropriate handling as follows:
-
-
-<OL>
-<LI>Define the tag in <B>tiff.h</B>.
-<LI>Add a field to the directory structure in <B>tif_dir.h</B>
- and define a <TT>FIELD_*</TT> bit (also update the definition of
- <TT>FIELD_CODEC</TT> to reflect your addition).
-<LI>Add an entry in the <TT>TIFFFieldInfo</TT> array defined at the top of
- <B>tif_dirinfo.c</B>.
- Note that you must keep this array sorted by tag
- number and that the widest variant entry for a tag should come
- first (e.g. <TT>LONG</TT> before <TT>SHORT</TT>).
-<LI>Add entries in <TT>_TIFFVSetField()</TT> and <TT>_TIFFVGetField()</TT>
- for the new tag.
-<LI>(<I>optional</I>) If the value associated with the tag is not a scalar value
- (e.g. the array for <TT>TransferFunction</TT>) and requires
- special processing,
- then add the appropriate code to <TT>TIFFReadDirectory()</TT> and
- <TT>TIFFWriteDirectory()</TT>. You're best off finding a similar tag and
- cribbing code.
-<LI>Add support to <TT>TIFFPrintDirectory()</TT> in <B>tif_print.c</B>
- to print the tag's value.
-</OL>
-
-<P>
-If you want to maintain portability, beware of making assumptions
-about data types. Use the typedefs (<TT>uint16</TT>, etc. when dealing with
-data on disk and <TT>t*_t</TT> when stuff is in memory) and be careful about
-passing items through printf or similar vararg interfaces.
-
-<A NAME=AddingCODECTags><P><H2>Adding New Codec-private Tags</H2></A>
-
-To add tags that are meaningful <EM>only when a particular compression
-algorithm is used</EM> follow these steps:
-
-<OL>
-<LI>Define the tag in <B>tiff.h</B>.
-<LI>Allocate storage for the tag values in the private state block of
- the codec.
-<LI>Insure the state block is created when the codec is initialized.
-<LI>At <TT>TIFFInitfoo</TT> time override the method pointers in the
- TIFF structure
- for getting, setting and printing tag values. For example,
-<PRE>
- sp->vgetparent = tif->tif_vgetfield;
- tif->tif_vgetfield = fooVGetField; /* hook for codec tags */
- sp->vsetparent = tif->tif_vsetfield;
- tif->tif_vsetfield = fooVSetField; /* hook for codec tags */
- tif->tif_printdir = fooPrintDir; /* hook for codec tags */
-</PRE>
- (Actually you may decide not to override the
- <TT>tif_printdir</TT> method, but rather just specify it).
-<LI>Create a private <TT>TIFFFieldInfo</TT> array for your tags and
- merge them into the core tags at initialization time using
- <TT>_TIFFMergeFieldInfo</TT>; e.g.
-<PRE>
- _TIFFMergeFieldInfo(tif, fooFieldInfo, N(fooFieldInfo));
-</PRE>
- (where <TT>N</TT> is a macro used liberaly throughout the distributed code).
-<LI>Fill in the get and set routines. Be sure to call the parent method
- for tags that you are not handled directly. Also be sure to set the
- <TT>FIELD_*</TT> bits for tags that are to be written to the file. Note that
- you can create ``pseudo-tags'' by defining tags that are processed
- exclusively in the get/set routines and never written to file (see
- the handling of <TT>TIFFTAG_FAXMODE</TT> in <B>tif_fax3.c</B>
- for an example of this).
-<LI>Fill in the print routine, if appropriate.
-</OL>
-
-Note that space has been allocated in the <TT>FIELD_*</TT> bit space for
-codec-private tags. Define your bits as <TT>FIELD_CODEC+&lt;offset&gt;</TT> to
-keep them away from the core tags. If you need more tags than there
-is room for, just increase <TT>FIELD_SETLONGS</TT> at the top of
-<B>tiffiop.h</B>.

-This chapter contains step-by-step instructions on how to configure
-and build the TIFF software distribution. The software is most
-easily built on a UNIX system, but with a little bit of work it can
-easily be built and used on other non-UNIX platforms.
-<hr>
-<a name="UNIX" id="UNIX"></a>
-<h2>Building on a UNIX System</h2>
-To build the software on a UNIX system you need to first run the
-configure shell script that is located in the top level of the
-source directory. This script probes the target system for
-necessary tools and functions and constructs a build environment in
-which the software may be compiled. Once configuration is done, you
-simply run <tt>make</tt> (or <tt>gmake</tt>) to build the software
-and then <tt>make install</tt> to do the installation; for example:
-<div style="margin-left: 2em">
-<pre>
-hyla% <b>cd ./tiff-4.0.0</b>
-hyla% <b>./configure</b>
- <i>...lots of messages...</i>
-hyla% <b>make</b>
- <i>...lots of messages...</i>
-hyla% <b>make check</b>
- <i>...lots of messages...</i>
-hyla# <b>make install</b>
-</pre></div>
-Supplied makefiles are dependent on a <tt>make</tt> utility and a C
-(and optionally a C++ compiler), so you will need these tools.
-<p>In general, the software is designed such that the following
-should be ``<i>make-able</i>'' in each directory:</p>
-<div style="margin-left: 2em">
-<pre>
-make [all] build stuff
-make check run the test suite
-make install build&amp;install stuff
-make clean remove .o files, executables and cruft
-make distclean remove everything, that can be recreated
-</pre></div>
-Note that after running "<tt>make distclean</tt>" the
-<tt>configure</tt> script must be run again to create the Makefiles
-and other make-related files. <a name="BuildTrees" id=
-"BuildTrees"></a>
-<hr width="65%" align="right">
-<h3>Build Trees</h3>
-There are two schemes for configuring and building the software. If
-you intend to build the software for only one target system, you
-can configure the software so that it is built in the same
-directories as the source code.
-<div style="margin-left: 2em">
-<pre>
-hyla% <b>gzip -dc tiff-4.0.0.tar.gz | tar -xf -</b>
-hyla% <b>cd ./tiff-4.0.0</b>
-hyla% <b>./configure</b>
-hyla% <b>make</b>
-hyla% <b>make check</b>
-hyla% <b>make install</b>
-</pre></div>
-<p>Otherwise, you can configure a build tree that is parallel to
-the source tree hierarchy (or in some completely different place)
-but which contains only configured files and files created during
-the build procedure.</p>
-<div style="margin-left: 2em">
-<pre>
-hyla% <b>gzip -dc tiff-4.0.0.tar.gz | tar -xf -</b>
-hyla% <b>mkdir tiff-4.0.0-build</b>
-hyla% <b>cd ./tiff-4.0.0-build</b>
-hyla% <b>../tiff-4.0.0/configure</b>
-hyla% <b>make</b>
-hyla% <b>make check</b>
-hyla% <b>make install</b>
-</pre></div>
-This second scheme is useful for:
-<ul>
-<li>building multiple targets from a single source tree</li>
-<li>building from a read-only source tree (e.g. if you receive the
-distribution on CD-ROM)</li>
-<li>sharing the source files via a network, but building on
-multiple systems</li>
-</ul>
-<a name="ConfigOptions" id="ConfigOptions"></a>
-<hr width="65%" align="right">
-<h3>Configuration Options</h3>
-The configuration process is critical to the proper compilation,
-installation, and operation of the software. The configure script
-runs a series of tests to decide whether or not the target system
-supports required functionality and, if it does not, whether it can
-emulate or workaround the missing functions. This procedure is
-fairly complicated and, due to the nonstandard nature of most UNIX
-systems, prone to error. The first time that you configure the
-software for use you should check the output from the configure
-script and look for anything that does not make sense for your
-system.
-<p>A second function of the configure script is to set the default
-configuration parameters for the software. Of particular note are
-the directories where the software is to be installed. By default
-the software is installed in the <b>/usr/local</b> hierarchy. To
-change this behaviour the appropriate parameters can be specified
-on the command line to configure. Run <b>./configure --help</b> to
-get a full list of possible options. Standard installation related
-options are shown below.</p>
-<pre>
-<tt>
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [/usr/local]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, `make install' will install all the files in
-`/usr/local/bin', `/usr/local/lib' etc. You can specify
-an installation prefix other than `/usr/local' using `--prefix',
-for instance `--prefix=$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]
- --docdir=DIR documentation root [DATAROOTDIR/doc/tiff]
- --htmldir=DIR html documentation [DOCDIR]
-
-Program names:
- --program-prefix=PREFIX prepend PREFIX to installed program names
- --program-suffix=SUFFIX append SUFFIX to installed program names
- --program-transform-name=PROGRAM run sed PROGRAM on installed program names
-</tt>
-</pre>
-<a name="Packages" id="Packages"></a>
-<hr width="65%" align="right">
-<h3>Configuring Optional Packages/Support</h3>
-The TIFF software comes with several packages that are installed
-only as needed, or only if specifically configured at the time the
-configure script is run. Packages can be configured via the
-<b>configure</b> script commandline parameters.
-<dl>
-<dt><i>Static/Shared Objects Support</i></dt>
-<dd><tt>--enable-shared[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build shared
-libraries [default=yes]<br>
---enable-static[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build static
-libraries [default=yes]</tt>
-<p>These options control whether or not to configure the software
-to build a shared and static binaries for the TIFF library. Use of
-shared libraries can significantly reduce the disk space needed for
-users of the TIFF software. If shared libarries are not used then
-the code is statically linked into each application that uses it.
-By default both types of binaries is configured.</p>
-<p>
-<tt>--enable-rpath&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Enable
-runtime linker paths (-R libtool option)</tt></p>
-<p>Add library directories (see other options below) to the TIFF
-library run-time linker path.</p>
-<p><tt>--enable-ld-version-script&nbsp;&nbsp;Enable linker version
-script (default is disabled)</tt></p>
-<p>Add shared library symbol versioning on ELF-based systems (e.g.
-Linux and FreeBSD) which use the GNU linker. This is needed if
-several major versions of libtiff might be loaded at once into the
-same program.</p>
-</dd>
-<dt><i>JPEG Support</i></dt>
-<dd><tt>--disable-jpeg&nbsp;&nbsp;&nbsp;&nbsp;disable IJG JPEG
-library usage (required for JPEG compression, enabled by default)
---with-jpeg-include-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;location of IJG
-JPEG library headers
---with-jpeg-lib-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;location of IJG JPEG
-library binary)</tt></dd>
-<dd>The <tt>JPEG</tt> package enables support for the handling of
-TIFF images with JPEG-encoded data. Support for JPEG-encoded data
-requires the Independent JPEG Group (IJG) <tt>libjpeg</tt>
-distribution; this software is available at <a href=
-"http://www.ijg.org/">http://www.ijg.org/</a>. <b>configure</b>
-script automatically tries to search for a working IJG JPEG
-installation. If it fails to find library, JPEG support will be
-automatically disabled.If you want specify the exact paths to
-library binary and headers, use above switches for that.</dd>
-<dt><i>ZIP Support</i></dt>
-<dd>The <tt>ZIP</tt> support enables support for the handling of
-TIFF images with deflate-encoded data. Support for deflate-encoded
-data requires the freely available <tt>zlib</tt> distribution
-written by Jean-loup Gailly and Mark Adler; this software is
-available at <a href=
-"http://www.zlib.org/">http://www.zlib.org/</a>. If ZIP support is
-enabled the <tt>DIRS_LIBINC</tt> and <tt>DIR_GZLIB</tt> parameters
-should also be set (see below). By default this package is not
-configured.</dd>

-<h2>Building the Software under Windows 95/98/NT/2000 with MS
-VC++</h2>
-With Microsoft Visual C++ installed, and properly configured for
-commandline use (you will likely need to source VCVARS32.BAT in
-AUTOEXEC.bAT or somewhere similar) you should be able to use the
-provided <tt>makefile.vc</tt>.
-<p>The source package is delivered using Unix line termination
-conventions, which work with MSVC but do not work with Windows
-'notepad'. If you use unzip from the <a href=
-"http://www.info-zip.org/pub/infozip/">Info-Zip</a> package, you
-can extract the files using Windows normal line termination
-conventions with a command similar to:</p>
-<pre>
- unzip -aa -a tiff-4.0.0.zip
-</pre>
-<p>By default libtiff expects that a pre-built zlib and jpeg
-library are provided by the user. If this is not the case, then you
-may edit libtiff\tiffconf.h using a text editor (e.g. notepad) and
-comment out the entries for JPEG_SUPPORT, PIXARLOG_SUPPORT, and
-ZIP_SUPPORT. Ignore the comment at the top of the file which says
-that it has no influence on the build, because the statement is not
-true for Windows. However, by taking this approach, libtiff will
-not be able to open some TIFF files.</p>
-<p>To build using the provided makefile.vc you may use:</p>
-<pre>
- C:\tiff-4.0.0&gt; nmake /f makefile.vc clean
- C:\tiff-4.0.0&gt; nmake /f makefile.vc
-
- or (the hard way)
-
- C:\tiff-4.0.0&gt; cd port
- C:\tiff-4.0.0\port&gt; nmake /f makefile.vc clean
- C:\tiff-4.0.0\port&gt; nmake /f makefile.vc
- C:\tiff-4.0.0&gt; cd ../libtiff
- C:\tiff-4.0.0\libtiff&gt; nmake /f makefile.vc clean
- C:\tiff-4.0.0\libtiff&gt; nmake /f makefile.vc
- C:\tiff-4.0.0\libtiff&gt; cd ..\tools
- C:\tiff-4.0.0\tools&gt; nmake /f makefile.vc clean
- C:\tiff-4.0.0\tools&gt; nmake /f makefile.vc
-</pre>
-<p>This will build the library file
-<tt>libtiff\libtiff\libtiff.lib</tt>. This can be used in Win32
-programs. You may want to adjust the build options before start
-compiling. All parameters contained in the <tt>nmake.opt</tt>
-file.This is a plain text file you can open with your favorite text
-editor.</p>
-<p>The makefile also builds a DLL (libtiff.dll) with an associated
-import library (libtiff_i.lib). Any builds using libtiff will need
-to include the LIBTIFF\LIBTIFF directory in the include path.</p>
-<p>The <tt>libtiff\tools\makefile.vc</tt> should build .exe's for
-all the standard TIFF tool programs.</p>

-<h2>Building the Software on a VMS System</h2>
-The VMS port was done by Karsten Spang (<a href=
-"mailto:krs@kampsax.dk">krs@kampsax.dk</a>), who also "sort of"
-maintains it. The VMS specific files are not in the main
-directories. Instead they are placed under
-<tt>[.CONTRIB.VMS...]</tt> in the distribution tree. Installation:
-It is assumed that you have unpacked the tar file into a VMS
-directory tree, in this text called DISK:[TIFF].
-<ol>
-<li>Move the VMS specific files to their proper directories.
-<pre>
-$ SET DEFAULT DISK:[TIFF.CONTRIB.VMS]

-You will want to add these lines to your <tt>LOGIN.COM</tt> file,
-after changing the name of the directory that you have used on your
-machine.
-<p>This release has been tested on OpenVMS/VAX 5.5-2, using VAX C
-3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC
-C ?.?, it is believed that this release as well works on AXP. The
-code contains some GNU C specific things. This does *not* imply,
-however, that the VAX/GCC configuration has been tested, *it has
-not*.</p>
-<p>The command procedures (<tt>MAKEVMS.COM</tt>) for building the
-library and tools, is believed to choose the correct options for
-the VAX and AXP cases automatically.</p>
-<p>On the AXP, IEEE floating point is used by default. If you want
-VAX floating point, remove the <tt>/FLOAT=IEEE_FLOAT</tt>
-qualifier, and change <tt>HAVE_IEEEFP=1</tt> to
-<tt>HAVE_IEEEFP=0</tt> in the <tt>MAKEVMS.COM</tt> files in both
-the <b>libtiff</b> and <b>tools</b> directories.</p>
-<h3>Compiling your own program on a VMS system:</h3>
-When compiling a source file in which you <tt>"#include
-&lt;tiffio.h&gt;"</tt>, use the following command
-<pre>
- $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
-</pre>
-This ensures that the header file is found. On the AXP, also add
-<tt>/FLOAT=IEEE_FLOAT</tt> (if used when building the library).
-<h3>Linking your own program to the TIFF library on a VMS
-system:</h3>
-You can link to the library in two ways: Either using the shareable
-library, or using the object library. On the VAX these
-possibilities are:
-<ol>
-<li>Using the shareable TIFF library.
-<pre>
-$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
- SYS$SHARE:VAXCRTL/SHAREABLE
-</pre></li>
-<li>Using the TIFF object library.
-<pre>
-$ LINK MY_PROGRAM, -
- DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
- SYS$INPUT:/OPTIONS
- SYS$SHARE:VAXCRTL/SHAREABLE
-</pre></li>
-</ol>
-On AXP (and possibly also using DEC C on VAX) the corresponding
-commands are
-<ol>
-<li>Using the shareable TIFF library.
-<pre>
-$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
-</pre></li>
-<li>Using the TIFF object library.
-<pre>
-$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
-</pre></li>
-</ol>
-Method 1 uses the shortest link time and smallest <tt>.EXE</tt>
-files, but it requires that <tt>TIFFSHR</tt> is defined as above at
-link time and <strong>at run time</strong>. Using the compilation
-procedure above, the tools are linked in this way.
-<p>Method 2 gives somewhat longer link time and larger
-<tt>.EXE</tt> files, but does not require <tt>TIFFSHR</tt> to be
-defined. This method is recommended if you want to run your program
-on another machine, and for some reason don't want to have the
-library on that machine. If you plan to have more than one program
-(including the tools) on the machine, it is recommended that you
-copy the library to the other machine and use method 1.</p>
-<hr>
-<a name="Other" id="Other"></a>
-<h2>Building the Software on Other Systems</h2>
-This section contains information that might be useful if you are
-working on a non-UNIX system that is not directly supported. All
-library-related files described below are located in the
-<b>libtiff</b> directory.
-<p>The library requires two files that are generated
-<i>on-the-fly</i>. The file <b>tif_fax3sm.c</b> has the state
-tables for the Group 3 and Group 4 decoders. This file is generated
-by the <tt>mkg3states</tt> program on a UNIX system; for
-example,</p>
-<div style="margin-left: 2em">
-<pre>
-<tt>
-cd libtiff
-cc -o mkg3states mkg3states.c
-rm -f tif_fax3sm.c
-./mkg3states -c const tif_fax3sm.c
-</tt>
-</pre></div>
-The <tt>-c</tt> option can be used to control whether or not the
-resutling tables are generated with a <tt>const</tt> declaration.
-The <tt>-s</tt> option can be used to specify a C storage class for
-the table declarations. The <tt>-b</tt> option can be used to force
-data values to be explicitly bracketed with ``{}'' (apparently
-needed for some MS-Windows compilers); otherwise the structures are
-emitted in as compact a format as possible. Consult the source code
-for this program if you have questions.
-<p>The second file required to build the library, <b>version.h</b>,
-contains the version information returned by the
-<tt>TIFFGetVersion</tt> routine. This file is built on most systems
-using the <tt>mkversion</tt> program and the contents of the
-<tt>VERSION</tt> and <tt>tiff.alpha</tt> files; for example,</p>
-<div style="margin-left: 2em">
-<pre>
-cd libtiff
-cc -o mkversion mkversion.c
-rm -f version.h
-./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
-</pre></div>
-<p>Otherwise, when building the library on a non-UNIX system be
-sure to consult the files <b>tiffcomp.h</b> and <b>tiffconf.h</b>.
-The former contains system compatibility definitions while the
-latter is provided so that the software configuration can be
-controlled on systems that do not support the make facility for
-building the software.</p>
-<p>Systems without a 32-bit compiler may not be able to handle some
-of the codecs in the library; especially the Group 3 and 4 decoder.
-If you encounter problems try disabling support for a particular
-codec; consult the <a href=
-"internals.html#Config">documentation</a>.</p>
-<p>Programs in the tools directory are written to assume an ANSI C
-compilation environment. There may be a few POSIX'isms as well. The
-code in the <b>port</b> directory is provided to emulate routines
-that may be missing on some systems. On UNIX systems the
-<tt>configure</tt> script automatically figures out which routines
-are not present on a system and enables the use of the equivalent
-emulation routines from the <b>port</b> directory. It may be
-necessary to manually do this work on a non-UNIX system. <a name=
-"Testing" id="Testing"></a></p>
-<hr>
-<h2>Checking out the Software</h2>
-<p>Assuming you have working versions of <tt>tiffgt</tt> and
-<tt>tiffsv</tt>, you can just use them to view any of the sample
-images available for testing (see the <a href="images.html">section
-on obtaining the test images</a>). Otherwise, you can do a cursory
-check of the library with the <tt>tiffcp</tt> and <tt>tiffcmp</tt>
-programs. For example,</p>
-<div style="margin-left: 2em">
-<pre>
-tiffcp -lzw cramps.tif x.tif
-tiffcmp cramps.tif x.tif
-</pre></div>
-<p>(<tt>tiffcmp</tt> should be silent if the files compare
-correctly). <a name="TOC" id="TOC"></a></p>

- This software provides support for the <i>Tag Image File Format</i> (TIFF),
- a widely used format for storing image data. The latest version of
- the TIFF specification is <a href="document.html">available on-line</a>
- in several different formats.
- </p>
- <p>
- Included in this software distribution is a library, libtiff, for
- reading and writing TIFF, a small collection of tools for doing
- simple manipulations of TIFF images, and documentation on the
- library and tools. Libtiff is a portable software, it was built
- and tested on various systems: UNIX flavors (Linux, BSD, Solaris,
- MacOS X), Windows, and OpenVMS. It should be possible to port
- libtiff and additional tools on other OSes.
- </p>
- <p>
- The library, along with associated tool programs, should handle most of
- your needs for reading and writing TIFF images on 32- and 64-bit
- machines.
- </p>
- <p>
- The software was originally authored and maintained by Sam Leffler.
- </p>
- <p>
- Questions should be sent to the TIFF mailing list:
- <a href="mailto:tiff@lists.maptools.org">tiff@lists.maptools.org</a>, with
- a subscription interface at
- <a href="http://lists.maptools.org/mailman/listinfo/tiff">http://lists.maptools.org/mailman/listinfo/tiff</a>.

-

-<P>
-This chapter provides information about the internal structure of
-the library, how to control the configuration when building it, and
-how to add new support to the library.
-The following sections are found in this chapter:
-
-<UL>
-<LI><A HREF=#Config>Library Configuration</A>
-<LI><A HREF=#Portability>General Portability Comments</A>
-<LI><A HREF="#Types">Types and Portability</A>

-<LI><A HREF=#Other>Other Comments</A>
-</UL>
-
-
-<A NAME="Config"><P><HR WIDTH=65% ALIGN=right><H3>Library Configuration</H3></A>
-
-Information on compiling the library is given
-<A HREF=build.html>elsewhere in this documentation</A>.
-This section describes the low-level mechanisms used to control
-the optional parts of the library that are configured at build
-time. Control is based on
-a collection of C defines that are specified either on the compiler
-command line or in a configuration file such as <TT>port.h</TT>
-(as generated by the <TT>configure</TT> script for UNIX systems)
-or <B>tiffconf.h</B>.
-
-<P>
-Configuration defines are split into three areas:
-<UL>
-<LI>those that control which compression schemes are
- configured as part of the builtin codecs,
-<LI>those that control support for groups of tags that
- are considered optional, and
-<LI>those that control operating system or machine-specific support.
-</UL>
-
-<P>
-If the define <TT>COMPRESSION_SUPPORT</TT> is <STRONG>not defined</STRONG>
-then a default set of compression schemes is automatically
-configured:
-<UL>
-<LI>CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771),
-<LI>the Macintosh PackBits algorithm (compression 32773),
-<LI>a 4-bit run-length encoding scheme from ThunderScan (compression 32809),
-<LI>a 2-bit encoding scheme used by NeXT (compression 32766), and
-<LI>two experimental schemes intended for images with high dynamic range
-(compression 34676 and 34677).
-</UL>
-
-<P>
-
-To override the default compression behaviour define
-<TT>COMPRESSION_SUPPORT</TT> and then one or more additional defines
-to enable configuration of the appropriate codecs (see the table
-below); e.g.
-
-<UL><PRE>
-#define COMPRESSION_SUPPORT
-#define CCITT_SUPPORT
-#define PACKBITS_SUPPORT
-</PRE></UL>
-
-Several other compression schemes are configured separately from
-the default set because they depend on ancillary software
-packages that are not distributed with <TT>libtiff</TT>.
-
-<P>
-Support for JPEG compression is controlled by <TT>JPEG_SUPPORT</TT>.
-The JPEG codec that comes with <TT>libtiff</TT> is designed for
-use with release 5 or later of the Independent JPEG Group's freely
-available software distribution.
-This software can be retrieved from the directory
-<A HREF=ftp://ftp.uu.net/graphics/jpeg>ftp.uu.net:/graphics/jpeg/</A>.
-
-
-<P>
-<IMG SRC="images/info.gif" ALT="NOTE: " ALIGN=left HSPACE=8>
-<EM>Enabling JPEG support automatically enables support for
-the TIFF 6.0 colorimetry and YCbCr-related tags.</EM>
-
-<P>
-Experimental support for the deflate algorithm is controlled by
-<TT>DEFLATE_SUPPORT</TT>.
-The deflate codec that comes with <TT>libtiff</TT> is designed
-for use with version 0.99 or later of the freely available
-<TT>libz</TT> library written by Jean-loup Gailly and Mark Adler.
-The data format used by this library is described
-in the files
-<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/zlib-3.1.doc>zlib-3.1.doc</A>,
-and
-<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/deflate-1.1.doc>deflate-1.1.doc</A>,
-available in the directory
-<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc>ftp.uu.net:/pub/archiving/zip/doc</A>.</EM>
-The library can be retried from the directory
-<A HREF=ftp://ftp.uu.net/pub/archiving/zip/zlib/>ftp.uu.net:/pub/archiving/zip/zlib/</A>
-(or try <A HREF=ftp://quest.jpl.nasa.gov/beta/zlib/>quest.jpl.nasa.gov:/beta/zlib/</A>).
-
-<P>
-<IMG SRC="images/warning.gif" ALT="NOTE: " ALIGN=left HSPACE=8 VSPACE=6>
-<EM>The deflate algorithm is experimental. Do not expect
-to exchange files using this compression scheme;
-it is included only because the similar, and more common,
-LZW algorithm is claimed to be governed by licensing restrictions.</EM>

-<A NAME="Portability"><P><HR WIDTH=65% ALIGN=right><H3>General Portability Comments</H3></A>
-
-This software is developed on Silicon Graphics UNIX
-systems (big-endian, MIPS CPU, 32-bit ints,
-IEEE floating point).
-The <TT>configure</TT> shell script generates the appropriate
-include files and make files for UNIX systems.
-Makefiles exist for non-UNIX platforms that the
-code runs on -- this work has mostly been done by other people.
-
-<P>
-In general, the code is guaranteed to work only on SGI machines.
-In practice it is highly portable to any 32-bit or 64-bit system and much
-work has been done to insure portability to 16-bit systems.
-If you encounter portability problems please return fixes so
-that future distributions can be improved.
-
-<P>
-The software is written to assume an ANSI C compilation environment.
-If your compiler does not support ANSI function prototypes, <TT>const</TT>,
-and <TT>&lt;stdarg.h&gt;</TT> then you will have to make modifications to the
-software. In the past I have tried to support compilers without <TT>const</TT>
-and systems without <TT>&lt;stdarg.h&gt;</TT>, but I am
-<EM>no longer interested in these
-antiquated environments</EM>. With the general availability of
-the freely available GCC compiler, I
-see no reason to incorporate modifications to the software for these
-purposes.
-
-<P>
-An effort has been made to isolate as many of the
-operating system-dependencies
-as possible in two files: <B>tiffcomp.h</B> and
-<B>libtiff/tif_&lt;os&gt;.c</B>. The latter file contains
-operating system-specific routines to do I/O and I/O-related operations.
-The UNIX (<B>tif_unix.c</B>),
-Macintosh (<B>tif_apple.c</B>),
-and VMS (<B>tif_vms.c</B>)
-code has had the most use;
-the MS/DOS support (<B>tif_msdos.c</B>) assumes
-some level of UNIX system call emulation (i.e.
-<TT>open</TT>,
-<TT>read</TT>,
-<TT>write</TT>,
-<TT>fstat</TT>,
-<TT>malloc</TT>,
-<TT>free</TT>).
-
-<P>
-Native CPU byte order is determined on the fly by
-the library and does not need to be specified.
-The <TT>HOST_FILLORDER</TT> and <TT>HOST_BIGENDIAN</TT>
-definitions are not currently used, but may be employed by
-codecs for optimization purposes.
-

-
-<P>
-On UNIX systems <TT>HAVE_MMAP</TT> is defined through the running of
-the <TT>configure</TT> script; otherwise support for memory-mapped

-1 (<TT>BSDTYPES</TT> is not defined).
-
-
-<A NAME="Types"><P><HR WIDTH=65% ALIGN=right><H3>Types and Portability</H3></A>
-
-The software makes extensive use of C typedefs to promote portability.
-Two sets of typedefs are used, one for communication with clients
-of the library and one for internal data structures and parsing of the
-TIFF format. There are interactions between these two to be careful
-of, but for the most part you should be able to deal with portability
-purely by fiddling with the following machine-dependent typedefs:

-
-</TABLE>
-
-<P>
-Note that <TT>tstrip_t</TT>, <TT>ttile_t</TT>, and <TT>tsize_t</TT>
-are constrained to be
-no more than 32-bit quantities by 32-bit fields they are stored
-in in the TIFF image. Likewise <TT>tsample_t</TT> is limited by the 16-bit
-field used to store the <TT>SamplesPerPixel</TT> tag. <TT>tdir_t</TT>
-constrains
-the maximum number of IFDs that may appear in an image and may
-be an arbitrary size (without penalty). <TT>ttag_t</TT> must be either
-<TT>int</TT>, <TT>unsigned int</TT>, pointer, or <TT>double</TT>
-because the library uses a varargs
-interface and ANSI C restricts the type of the parameter before an
-ellipsis to be a promoted type. <TT>toff_t</TT> is defined as
-<TT>int32</TT> because
-TIFF file offsets are (unsigned) 32-bit quantities. A signed
-value is used because some interfaces return -1 on error (sigh).
-Finally, note that <TT>tidata_t</TT> is used internally to the library to
-manipulate internal data. User-specified data references are
-passed as opaque handles and only cast at the lowest layers where
-their type is presumed.
-
-
-<P><HR WIDTH=65% ALIGN=right><H3>General Comments</H3></A>
-
-The library is designed to hide as much of the details of TIFF from
-applications as
-possible. In particular, TIFF directories are read in their entirety
-into an internal format. Only the tags known by the library are
-available to a user and certain tag data may be maintained that a user
-does not care about (e.g. transfer function tables).
-
-<A NAME=AddingCODECS><P><HR WIDTH=65% ALIGN=right><H3>Adding New Builtin Codecs</H3></A>
-
-To add builtin support for a new compression algorithm, you can either
-use the "tag-extension" trick to override the handling of the
-TIFF Compression tag (see <A HREF=addingtags.html>Adding New Tags</A>),
-or do the following to add support directly to the core library:
-
-<OL>
-<LI>Define the tag value in <B>tiff.h</B>.
-<LI>Edit the file <B>tif_codec.c</B> to add an entry to the
- _TIFFBuiltinCODECS array (see how other algorithms are handled).
-<LI>Add the appropriate function prototype declaration to
- <B>tiffiop.h</B> (close to the bottom).
-<LI>Create a file with the compression scheme code, by convention files
- are named <B>tif_*.c</B> (except perhaps on some systems where the
- tif_ prefix pushes some filenames over 14 chars.
-<LI>Edit <B>Makefile.in</B> (and any other Makefiles)
- to include the new source file.
-</OL>
-
-<P>
-A codec, say <TT>foo</TT>, can have many different entry points:
-
-<PRE>
-TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */
-fooSetupDecode(tif) /* called once per IFD after tags has been frozen */
-fooPreDecode(tif, sample)/* called once per strip/tile, after data is read,
- but before the first row is decoded */
-fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
- fooDecodeRow(...) /* called to decode a single scanline */
- fooDecodeStrip(...) /* called to decode an entire strip */
- fooDecodeTile(...) /* called to decode an entire tile */
-fooSetupEncode(tif) /* called once per IFD after tags has been frozen */
-fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in
- a strip/tile is encoded */
-fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
- fooEncodeRow(...) /* called to decode a single scanline */
- fooEncodeStrip(...) /* called to decode an entire strip */
- fooEncodeTile(...) /* called to decode an entire tile */
-fooPostEncode(tif) /* called once per strip/tile, just before data is written */
-fooSeek(tif, row) /* seek forwards row scanlines from the beginning
- of a strip (row will always be &gt;0 and &lt;rows/strip */
-fooCleanup(tif) /* called when compression scheme is replaced by user */
-</PRE>
-
-<P>
-Note that the encoding and decoding variants are only needed when
-a compression algorithm is dependent on the structure of the data.
-For example, Group 3 2D encoding and decoding maintains a reference
-scanline. The sample parameter identifies which sample is to be
-encoded or decoded if the image is organized with <TT>PlanarConfig</TT>=2
-(separate planes). This is important for algorithms such as JPEG.
-If <TT>PlanarConfig</TT>=1 (interleaved), then sample will always be 0.
-
-<A NAME=Other><P><HR WIDTH=65% ALIGN=right><H3>Other Comments</H3></A>
-
-The library handles most I/O buffering. There are two data buffers
-when decoding data: a raw data buffer that holds all the data in a
-strip, and a user-supplied scanline buffer that compression schemes
-place decoded data into. When encoding data the data in the
-user-supplied scanline buffer is encoded into the raw data buffer (from
-where it is written). Decoding routines should never have to explicitly
-read data -- a full strip/tile's worth of raw data is read and scanlines
-never cross strip boundaries. Encoding routines must be cognizant of
-the raw data buffer size and call <TT>TIFFFlushData1()</TT> when necessary.
-Note that any pending data is automatically flushed when a new strip/tile is
-started, so there's no need do that in the tif_postencode routine (if
-one exists). Bit order is automatically handled by the library when
-a raw strip or tile is filled. If the decoded samples are interpreted
-by the decoding routine before they are passed back to the user, then
-the decoding logic must handle byte-swapping by overriding the
-<TT>tif_postdecode</TT>
-routine (set it to <TT>TIFFNoPostDecode</TT>) and doing the required work
-internally. For an example of doing this look at the horizontal
-differencing code in the routines in <B>tif_predict.c</B>.
-
-<P>
-The variables <TT>tif_rawcc</TT>, <TT>tif_rawdata</TT>, and
-<TT>tif_rawcp</TT> in a <TT>TIFF</TT> structure
-are associated with the raw data buffer. <TT>tif_rawcc</TT> must be non-zero
-for the library to automatically flush data. The variable
-<TT>tif_scanlinesize</TT> is the size a user's scanline buffer should be. The
-variable <TT>tif_tilesize</TT> is the size of a tile for tiled images. This
-should not normally be used by compression routines, except where it
-relates to the compression algorithm. That is, the <TT>cc</TT> parameter to the
-<TT>tif_decode*</TT> and <TT>tif_encode*</TT>
-routines should be used in terminating
-decompression/compression. This ensures these routines can be used,
-for example, to decode/encode entire strips of data.
-
-<P>
-In general, if you have a new compression algorithm to add, work from
-the code for an existing routine. In particular,
-<B>tif_dumpmode.c</B>
-has the trivial code for the "nil" compression scheme,
-<B>tif_packbits.c</B> is a
-simple byte-oriented scheme that has to watch out for buffer
-boundaries, and <B>tif_lzw.c</B> has the LZW scheme that has the most
-complexity -- it tracks the buffer boundary at a bit level.
-Of course, using a private compression scheme (or private tags) limits
-the portability of your TIFF files.

-In order to better understand how TIFF works (and consequently this
-software) it is important to recognize the distinction between the
-physical organization of image data as it is stored in a TIFF and how
-the data is interpreted and manipulated as pixels in an image. TIFF
-supports a wide variety of storage and data compression schemes that
-can be used to optimize retrieval time and/or minimize storage space.
-These on-disk formats are independent of the image characteristics; it
-is the responsibility of the TIFF reader to process the on-disk storage
-into an in-memory format suitable for an application. Furthermore, it
-is the responsibility of the application to properly interpret the
-visual characteristics of the image data. TIFF defines a framework for
-specifying the on-disk storage format and image characteristics with
-few restrictions. This permits significant complexity that can be
-daunting. Good applications that handle TIFF work by handling as wide
-a range of storage formats as possible, while constraining the
-acceptable image characteristics to those that make sense for the
-application.

- <h1>Using The TIFF Library</h1>
- <p>
- <tt>libtiff</tt> is a set of C functions (a library) that support
- the manipulation of TIFF image files.
- The library requires an ANSI C compilation environment for building
- and presumes an ANSI C environment for use.
- </p>
- </td>
- </tr>
- </table>
- <br>
- <p>
- <tt>libtiff</tt>
- provides interfaces to image data at several layers of abstraction (and cost).
- At the highest level image data can be read into an 8-bit/sample,
- ABGR pixel raster format without regard for the underlying data organization,
- colorspace, or compression scheme. Below this high-level interface
- the library provides scanline-, strip-, and tile-oriented interfaces that
- return data decompressed but otherwise untransformed. These interfaces
- require that the application first identify the organization of stored
- data and select either a strip-based or tile-based API for manipulating
- data. At the lowest level the library
- provides access to the raw uncompressed strips or tiles,
- returning the data exactly as it appears in the file.
- </p>
- <p>
- The material presented in this chapter is a basic introduction
- to the capabilities of the library; it is not an attempt to describe
- everything a developer needs to know about the library or about TIFF.
- Detailed information on the interfaces to the library are given in
- the <a href="http://www.remotesensing.org/libtiff/man/index.html">UNIX
- manual pages</a> that accompany this software.
- </p>
- <p>
- Michael Still has also written a useful introduction to libtiff for the
- IBM DeveloperWorks site available at
- <a href="http://www.ibm.com/developerworks/linux/library/l-libtiff">http://www.ibm.com/developerworks/linux/library/l-libtiff</a>.

- <hr>
- <h2 id="version">How to tell which version you have</h2>
- <p>
- The software version can be found by looking at the file named
- <tt>VERSION</tt>
- that is located at the top of the source tree; the precise alpha number
- is given in the file <tt>dist/tiff.alpha</tt>.
- If you have need to refer to this
- specific software, you should identify it as:
- </p>
- <p style="margin-left: 40px">
- <tt>TIFF &lt;<i>version</i>&gt; &lt;<i>alpha</i>&gt;</tt>
- </p>
- <p>
- where <tt>&lt;<i>version</i>&gt;</tt> is whatever you get from
- <tt>"cat VERSION"</tt> and <tt>&lt;<i>alpha</i>&gt;</tt> is
- what you get from <tt>"cat dist/tiff.alpha"</tt>.
- </p>
- <p>
- Within an application that uses <tt>libtiff</tt> the <tt>TIFFGetVersion</tt>
- routine will return a pointer to a string that contains software version
- information.
- The library include file <tt>&lt;tiffio.h&gt;</tt> contains a C pre-processor
- define <tt>TIFFLIB_VERSION</tt> that can be used to check library
- version compatiblity at compile time.
- </p>
- <hr>
- <h2 id="typedefs">Library Datatypes</h2>
- <p>
- <tt>libtiff</tt> defines a portable programming interface through the
- use of a set of C type definitions.
- These definitions, defined in in the files <b>tiff.h</b> and
- <b>tiffio.h</b>,
- isolate the <tt>libtiff</tt> API from the characteristics
- of the underlying machine.
- To insure portable code and correct operation, applications that use
- <tt>libtiff</tt> should use the typedefs and follow the function
- prototypes for the library API.
- </p>
- <hr>
- <h2 id="mman">Memory Management</h2>
- <p>
- <tt>libtiff</tt> uses a machine-specific set of routines for managing
- dynamically allocated memory.
- <tt>_TIFFmalloc</tt>, <tt>_TIFFrealloc</tt>, and <tt>_TIFFfree</tt>
- mimic the normal ANSI C routines.
- Any dynamically allocated memory that is to be passed into the library
- should be allocated using these interfaces in order to insure pointer
- compatibility on machines with a segmented architecture.
- (On 32-bit UNIX systems these routines just call the normal <tt>malloc</tt>,
- <tt>realloc</tt>, and <tt>free</tt> routines in the C library.)
- </p>
- <p>
- To deal with segmented pointer issues <tt>libtiff</tt> also provides
- <tt>_TIFFmemcpy</tt>, <tt>_TIFFmemset</tt>, and <tt>_TIFFmemmove</tt>
- routines that mimic the equivalent ANSI C routines, but that are
- intended for use with memory allocated through <tt>_TIFFmalloc</tt>
- and <tt>_TIFFrealloc</tt>.
- </p>
- <hr>
- <h2 id="errors">Error Handling</h2>
- <p>
- <tt>libtiff</tt> handles most errors by returning an invalid/erroneous
- value when returning from a function call.
- Various diagnostic messages may also be generated by the library.
- All error messages are directed to a single global error handler
- routine that can be specified with a call to <tt>TIFFSetErrorHandler</tt>.
- Likewise warning messages are directed to a single handler routine
- that can be specified with a call to <tt>TIFFSetWarningHandler</tt>
- </p>
- <hr>
- <h2 id="fio">Basic File Handling</h2>
- <p>
- The library is modeled after the normal UNIX stdio library.
- For example, to read from an existing TIFF image the
- file must first be opened:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ...<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- }</tt>
- </p>
- <p>
- The handle returned by <tt>TIFFOpen</tt> is <i>opaque</i>, that is
- the application is not permitted to know about its contents.
- All subsequent library calls for this file must pass the handle
- as an argument.
- </p>
- <p>
- To create or overwrite a TIFF image the file is also opened, but with
- a <tt>"w"</tt> argument:
- <p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "w");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ...<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- }</tt>
- </p>
- <p>
- If the file already exists it is first truncated to zero length.
- </p>
- <table>
- <tr>
- <td valign=top><img src="images/warning.gif" width="40" height="40" alt=""></td>
- <td><i>Note that unlike the stdio library TIFF image files may not be
- opened for both reading and writing;
- there is no support for altering the contents of a TIFF file.</i></td>
- </tr>
- </table>
- <p>
- <tt>libtiff</tt> buffers much information associated with writing a
- valid TIFF image. Consequently, when writing a TIFF image it is necessary
- to always call <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> to flush any
- buffered information to a file. Note that if you call <tt>TIFFClose</tt>
- you do not need to call <tt>TIFFFlush</tt>.
- </p>
- <hr>
- <h2 id="dirs">TIFF Directories</h2>
- <p>
- TIFF supports the storage of multiple images in a single file.
- Each image has an associated data structure termed a <i>directory</i>
- that houses all the information about the format and content of the
- image data.
- Images in a file are usually related but they do not need to be; it
- is perfectly alright to store a color image together with a black and
- white image.
- Note however that while images may be related their directories are
- not.
- That is, each directory stands on its own; their is no need to read
- an unrelated directory in order to properly interpret the contents
- of an image.
- </p>
- <p>
- <tt>libtiff</tt> provides several routines for reading and writing
- directories. In normal use there is no need to explicitly
- read or write a directory: the library automatically reads the first
- directory in a file when opened for reading, and directory information
- to be written is automatically accumulated and written when writing
- (assuming <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> are called).
- </p>
- <p>
- For a file open for reading the <tt>TIFFSetDirectory</tt> routine can
- be used to select an arbitrary directory; directories are referenced by
- number with the numbering starting at 0. Otherwise the
- <tt>TIFFReadDirectory</tt> and <tt>TIFFWriteDirectory</tt> routines can
- be used for sequential access to directories.
- For example, to count the number of directories in a file the following
- code might be used:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main(int argc, char* argv[])<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int dircount = 0;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;do {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;dircount++;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} while (TIFFReadDirectory(tif));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("%d directories in %s\n", dircount, argv[1]);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
- }</tt>
- </p>
- <p>
- Finally, note that there are several routines for querying the
- directory status of an open file:
- <tt>TIFFCurrentDirectory</tt> returns the index of the current
- directory and
- <tt>TIFFLastDirectory</tt> returns an indication of whether the
- current directory is the last directory in a file.
- There is also a routine, <tt>TIFFPrintDirectory</tt>, that can
- be called to print a formatted description of the contents of
- the current directory; consult the manual page for complete details.
- </p>
- <hr>
- <h2 id="tags">TIFF Tags</h2>
- <p>
- Image-related information such as the image width and height, number
- of samples, orientation, colorimetric information, etc.
- are stored in each image
- directory in <i>fields</i> or <i>tags</i>.
- Tags are identified by a number that is usually a value registered
- with the Aldus (now Adobe) Corporation.
- Beware however that some vendors write
- TIFF images with tags that are unregistered; in this case interpreting
- their contents is usually a waste of time.
- </p>
- <p>
- <tt>libtiff</tt> reads the contents of a directory all at once
- and converts the on-disk information to an appropriate in-memory
- form. While the TIFF specification permits an arbitrary set of
- tags to be defined and used in a file, the library only understands
- a limited set of tags.
- Any unknown tags that are encountered in a file are ignored.
- There is a mechanism to extend the set of tags the library handles
- without modifying the library itself;
- this is described <a href="addingtags.html">elsewhere</a>.
- </p>
- <p>
- <tt>libtiff</tt> provides two interfaces for getting and setting tag
- values: <tt>TIFFGetField</tt> and <tt>TIFFSetField</tt>.
- These routines use a variable argument list-style interface to pass
- parameters of different type through a single function interface.
- The <i>get interface</i> takes one or more pointers to memory locations
- where the tag values are to be returned and also returns one or
- zero according to whether the requested tag is defined in the directory.
- The <i>set interface</i> takes the tag values either by-reference or
- by-value.
- The TIFF specification defines
- <i>default values</i> for some tags.
- To get the value of a tag, or its default value if it is undefined,
- the <tt>TIFFGetFieldDefaulted</tt> interface may be used.
- </p>
- <p>
- The manual pages for the tag get and set routines specifiy the exact data types
- and calling conventions required for each tag supported by the library.
- </p>
- <hr>
- <h2 id="compression">TIFF Compression Schemes</h2>
- <p>
- <tt>libtiff</tt> includes support for a wide variety of
- data compression schemes.
- In normal operation a compression scheme is automatically used when
- the TIFF <tt>Compression</tt> tag is set, either by opening a file
- for reading, or by setting the tag when writing.
- </p>
- <p>
- Compression schemes are implemented by software modules termed <i>codecs</i>
- that implement decoder and encoder routines that hook into the
- core library i/o support.
- Codecs other than those bundled with the library can be registered
- for use with the <tt>TIFFRegisterCODEC</tt> routine.
- This interface can also be used to override the core-library
- implementation for a compression scheme.
- </p>
- <hr>
- <h2 id="byteorder">Byte Order</h2>
- <p>
- The TIFF specification says, and has always said, that
- <em>a correct TIFF
- reader must handle images in big-endian and little-endian byte order</em>.
- <tt>libtiff</tt> conforms in this respect.
- Consequently there is no means to force a specific
- byte order for the data written to a TIFF image file (data is
- written in the native order of the host CPU unless appending to
- an existing file, in which case it is written in the byte order
- specified in the file).
- </p>
- <hr>
- <h2 id="dataplacement">Data Placement</h2>
- <p>
- The TIFF specification requires that all information except an
- 8-byte header can be placed anywhere in a file.
- In particular, it is perfectly legitimate for directory information
- to be written after the image data itself.
- Consequently TIFF is inherently not suitable for passing through a
- stream-oriented mechanism such as UNIX pipes.
- Software that require that data be organized in a file in a particular
- order (e.g. directory information before image data) does not
- correctly support TIFF.
- <tt>libtiff</tt> provides no mechanism for controlling the placement
- of data in a file; image data is typically written before directory
- information.
- </p>
- <hr>
- <h2 id="tiffrgbaimage">TIFFRGBAImage Support</h2>
- <p>
- <tt>libtiff</tt> provides a high-level interface for reading image
- data from a TIFF file. This interface handles the details of
- data organization and format for a wide variety of TIFF files;
- at least the large majority of those files that one would normally
- encounter. Image data is, by default, returned as ABGR
- pixels packed into 32-bit words (8 bits per sample). Rectangular
- rasters can be read or data can be intercepted at an intermediate
- level and packed into memory in a format more suitable to the
- application.
- The library handles all the details of the format of data stored on
- disk and, in most cases, if any colorspace conversions are required:
- bilevel to RGB, greyscale to RGB, CMYK to RGB, YCbCr to RGB, 16-bit
- samples to 8-bit samples, associated/unassociated alpha, etc.
- </p>
- <p>
- There are two ways to read image data using this interface. If
- all the data is to be stored in memory and manipulated at once,
- then the routine <tt>TIFFReadRGBAImage</tt> can be used:
- </p>
- <p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main(int argc, char* argv[])<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 w, h;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;size_t npixels;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* raster;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &amp;w);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;h);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;npixels = w * h;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (raster != NULL) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFReadRGBAImage(tif, w, h, raster, 0)) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...process raster data...<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(raster);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
- }</tt>
- </p>
- <p>
- Note above that <tt>_TIFFmalloc</tt> is used to allocate memory for
- the raster passed to <tt>TIFFReadRGBAImage</tt>; this is important
- to insure the ``appropriate type of memory'' is passed on machines
- with segmented architectures.
- </p>
- <p>
- Alternatively, <tt>TIFFReadRGBAImage</tt> can be replaced with a
- more low-level interface that permits an application to have more
- control over this reading procedure. The equivalent to the above
- is:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main(int argc, char* argv[])<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFRGBAImage img;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char emsg[1024];<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFRGBAImageBegin(&amp;img, tif, 0, emsg)) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;size_t npixels;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* raster;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;npixels = img.width * img.height;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (raster != NULL) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFRGBAImageGet(&amp;img, raster, img.width, img.height)) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...process raster data...<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(raster);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFRGBAImageEnd(&amp;img);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFError(argv[1], emsg);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
- }</tt>
- </p>
- <p>
- However this usage does not take advantage of the more fine-grained
- control that's possible. That is, by using this interface it is
- possible to:
- </p>
- <ul>
- <li>repeatedly fetch (and manipulate) an image without opening
- and closing the file</li>
- <li>interpose a method for packing raster pixel data according to
- application-specific needs (or write the data at all)</li>
- <li>interpose methods that handle TIFF formats that are not already
- handled by the core library</li>
- </ul>
- <p>
- The first item means that, for example, image viewers that want to
- handle multiple files can cache decoding information in order to
- speedup the work required to display a TIFF image.
- </p>
- <p>
- The second item is the main reason for this interface. By interposing
- a "put method" (the routine that is called to pack pixel data in
- the raster) it is possible share the core logic that understands how
- to deal with TIFF while packing the resultant pixels in a format that
- is optimized for the application. This alternate format might be very
- different than the 8-bit per sample ABGR format the library writes by
- default. For example, if the application is going to display the image
- on an 8-bit colormap display the put routine might take the data and
- convert it on-the-fly to the best colormap indices for display.
- </p>
- <p>
- The last item permits an application to extend the library
- without modifying the core code.
- By overriding the code provided an application might add support
- for some esoteric flavor of TIFF that it needs, or it might
- substitute a packing routine that is able to do optimizations
- using application/environment-specific information.
- </p>
- <p>
- The TIFF image viewer found in <b>tools/sgigt.c</b> is an example
- of an application that makes use of the <tt>TIFFRGBAImage</tt>
- support.
- </p>
- <hr>
- <h2 id="scanlines">Scanline-based Image I/O</h2>
- <p>
- The simplest interface provided by <tt>libtiff</tt> is a
- scanline-oriented interface that can be used to read TIFF
- images that have their image data organized in strips
- (trying to use this interface to read data written in tiles
- will produce errors.)
- A scanline is a one pixel high row of image data whose width
- is the width of the image.
- Data is returned packed if the image data is stored with samples
- packed together, or as arrays of separate samples if the data
- is stored with samples separated.
- The major limitation of the scanline-oriented interface, other
- than the need to first identify an existing file as having a
- suitable organization, is that random access to individual
- scanlines can only be provided when data is not stored in a
- compressed format, or when the number of rows in a strip
- of image data is set to one (<tt>RowsPerStrip</tt> is one).
- </p>
- <p>
- Two routines are provided for scanline-based i/o:
- <tt>TIFFReadScanline</tt>
- and
- <tt>TIFFWriteScanline</tt>.
- For example, to read the contents of a file that
- is assumed to be organized in strips, the following might be used:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imagelength;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 row;<br>

- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffgetfield(tif, tifftag_samplesperpixel, &amp;nsamples);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (s = 0; s &lt; nsamples; s++)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++)<br>

- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- }</tt>
- </p>
- <p>
- Beware however that if the following code were used instead to
- read data in the case <tt>PLANARCONFIG_SEPARATE</tt>,...
- </p>
- <p style="margin-left: 40px">
- <tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (s = 0; s &lt; nsamples; s++)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row, s);</tt>
- </p>
- <p>
- ...then problems would arise if <tt>RowsPerStrip</tt> was not one
- because the order in which scanlines are requested would require
- random access to data within strips (something that is not supported
- by the library when strips are compressed).
- </p>
- <hr>
- <h2 id="strips">Strip-oriented Image I/O</h2>
- <p>
- The strip-oriented interfaces provided by the library provide
- access to entire strips of data. Unlike the scanline-oriented
- calls, data can be read or written compressed or uncompressed.
- Accessing data at a strip (or tile) level is often desirable
- because there are no complications with regard to random access
- to data within strips.
- </p>
- <p>
- A simple example of reading an image by strips is:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFStripSize(tif));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedstrip(tif, strip, buf, (tsize_t) -1);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- }</tt>
- </p>
- <p>
- Notice how a strip size of <tt>-1</tt> is used; <tt>TIFFReadEncodedStrip</tt>
- will calculate the appropriate size in this case.
- </p>
- <p>
- The above code reads strips in the order in which the
- data is physically stored in the file. If multiple samples
- are present and data is stored with <tt>PLANARCONFIG_SEPARATE</tt>
- then all the strips of data holding the first sample will be
- read, followed by strips for the second sample, etc.
- </p>
- <p>
- Finally, note that the last strip of data in an image may have fewer
- rows in it than specified by the <tt>RowsPerStrip</tt> tag. A
- reader should not assume that each decoded strip contains a full
- set of rows in it.
- </p>
- <p>
- The following is an example of how to read raw strips of data from
- a file:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* bc;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 stripsize;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &amp;bc);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[0];<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(stripsize);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (bc[strip] &gt; stripsize) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFrealloc(buf, bc[strip]);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[strip];<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFReadRawStrip(tif, strip, buf, bc[strip]);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(buf);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- }</tt>
- </p>
- <p>
- As above the strips are read in the order in which they are
- physically stored in the file; this may be different from the
- logical ordering expected by an application.
- </p>
- <hr>
- <h2 id="tiles">Tile-oriented Image I/O</h2>
- <p>
- Tiles of data may be read and written in a manner similar to strips.
- With this interface, an image is
- broken up into a set of rectangular areas that may have dimensions
- less than the image width and height. All the tiles
- in an image have the same size, and the tile width and length must each
- be a multiple of 16 pixels. Tiles are ordered left-to-right and
- top-to-bottom in an image. As for scanlines, samples can be packed
- contiguously or separately. When separated, all the tiles for a sample
- are colocated in the file. That is, all the tiles for sample 0 appear
- before the tiles for sample 1, etc.
- </p>
- <p>
- Tiles and strips may also be extended in a z dimension to form
- volumes. Data volumes are organized as "slices". That is, all the
- data for a slice is colocated. Volumes whose data is organized in
- tiles can also have a tile depth so that data can be organized in
- cubes.
- </p>
- <p>
- There are actually two interfaces for tiles.
- One interface is similar to scanlines, to read a tiled image,
- code of the following sort might be used:
- </p>
- <p style="margin-left: 40px">
- <tt>main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imageWidth, imageLength;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 tileWidth, tileLength;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 x, y;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &amp;imageWidth);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;imageLength);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILEWIDTH, &amp;tileWidth);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILELENGTH, &amp;tileLength);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (y = 0; y &lt; imagelength; y += tilelength)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (x = 0; x &lt; imagewidth; x += tilewidth)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadtile(tif, buf, x, y, 0);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- }</tt>
- </p>
- <p>
- (once again, we assume samples are packed contiguously.)
- </p>
- <p>
- Alternatively a direct interface to the low-level data is provided
- a la strips. Tiles can be read with
- <tt>TIFFReadEncodedTile</tt> or <tt>TIFFReadRawTile</tt>,
- and written with <tt>TIFFWriteEncodedTile</tt> or
- <tt>TIFFWriteRawTile</tt>. For example, to read all the tiles in an image:
- </p>
- <p style="margin-left: 40px">
- <tt>#include "tiffio.h"<br>
- main()<br>
- {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
- &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ttile_t tile;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif));<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (tile = 0; tile &lt; tiffnumberoftiles(tif); tile++)<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedtile(tif, tile, buf, (tsize_t) -1);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
- &nbsp;&nbsp;&nbsp;&nbsp;}<br>
- }</tt>

-<h2>DESCRIPTION
-<a name="DESCRIPTION"></a>
-</h2>
-
-
-
-<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFGetField</i></b>
-returns the value of a tag or pseudo-tag associated with the
-the current directory of the opened <small>TIFF</small> file
-<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
-to control the operation of the <small>TIFF</small> library
-but whose value is not read or written to the underlying
-file.) The file must have been previously opened with
-<i>TIFFOpen</i>(3TIFF). The tag is identified by <i>tag</i>,
-one of the values defined in the include file <b>tiff.h</b>
-(see also the table below). The type and number of values
-returned is dependent on the tag being requested. The
-programming interface uses a variable argument list as
-prescribed by the <i>stdarg</i>(3) interface. The returned
-values should only be interpreted if <i>TIFFGetField</i>
-returns 1.</p>
-
-
-<p style="margin-left:11%; margin-top: 1em"><i>TIFFVGetField</i>
-is functionally equivalent to <i>TIFFGetField</i> except
-that it takes a pointer to a variable argument list.
-<i>TIFFVGetField</i> is useful for layering interfaces on
-top of the functionality provided by
-<i>TIFFGetField</i>.</p>
-
-
-<p style="margin-left:11%; margin-top: 1em"><i>TIFFGetFieldDefaulted</i>
-and <i>TIFFVGetFieldDefaulted</i> are identical to
-<i>TIFFGetField</i> and <i>TIFFVGetField</i>, except that if
-a tag is not defined in the current directory and it has a
-default value, then the default value is returned.</p>
-
-<p style="margin-left:11%; margin-top: 1em">The tags
-understood by <i>libtiff(3TIFF),</i> the number of parameter
-values, and the types for the returned values are shown
-below. The data types are specified as in C and correspond
-to the types used to specify tag values to
-<i>TIFFSetField</i>(3TIFF). Remember that
-<i>TIFFGetField</i> returns parameter values, so all the
-listed data types are pointers to storage where values
-should be returned. Consult the <small>TIFF</small>
-specification (or relevant industry specification) for
-information on the meaning of each tag and their possible
-values.</p>

-<p><i>TIFFOpen</i> opens a <small>TIFF</small> file whose
-name is <i>filename</i> and returns a handle to be used in
-subsequent calls to routines in <i>libtiff</i>. If the open
-operation fails, then zero is returned. The <i>mode</i>
-parameter specifies if the file is to be opened for reading
-(&lsquo;&lsquo;r&rsquo;&rsquo;), writing
-(&lsquo;&lsquo;w&rsquo;&rsquo;), or appending
-(&lsquo;&lsquo;a&rsquo;&rsquo;) and, optionally, whether to
-override certain default aspects of library operation (see
-below). When a file is opened for appending, existing data
-will not be touched; instead new data will be written as
-additional subfiles. If an existing file is opened for
-writing, all previous data is overwritten.</p>
-<!-- INDENTATION -->
-<p>If a file is opened for reading, the first
-<small>TIFF</small> directory in the file is automatically
-read (also see <i>TIFFSetDirectory</i>(3TIFF) for reading
-directories other than the first). If a file is opened for
-writing or appending, a default directory is automatically
-created for writing subsequent data. This directory has all
-the default values specified in <small>TIFF</small> Revision
-6.0: <i>BitsPerSample</i>=1, <i>ThreshHolding</i>=bilevel
-art scan, <i>FillOrder</i>=1 (most significant bit of each
-data byte is filled first), <i>Orientation</i>=1 (the 0th
-row represents the visual top of the image, and the 0th
-column represents the visual left hand side),
-<i>SamplesPerPixel</i>=1, <i>RowsPerStrip</i>=infinity,
-<i>ResolutionUnit</i>=2 (inches), and <i>Compression</i>=1
-(no compression). To alter these values, or to define values
-for additional fields, <i>TIFFSetField</i>(3TIFF) must be
-used.</p>
-<!-- INDENTATION -->
-<p><i>TIFFFdOpen</i> is like <i>TIFFOpen</i> except that it
-opens a <small>TIFF</small> file given an open file
-descriptor <i>fd</i>. The file&rsquo;s name and mode must
-reflect that of the open descriptor. The object associated
-with the file descriptor <b>must support random
-access</b>.</p>
-<!-- INDENTATION -->
-<p><i>TIFFClientOpen</i> is like <i>TIFFOpen</i> except that
-the caller supplies a collection of functions that the
-library will use to do <small>UNIX</small> -like I/O
-operations. The <i>readproc</i> and <i>writeproc</i> are
-called to read and write data at the current file position.
-<i>seekproc</i> is called to change the current file
-position a la <i>lseek</i>(2). <i>closeproc</i> is invoked
-to release any resources associated with an open file.
-<i>sizeproc</i> is invoked to obtain the size in bytes of a
-file. <i>mapproc</i> and <i>unmapproc</i> are called to map
-and unmap a file&rsquo;s contents in memory; c.f.
-<i>mmap</i>(2) and <i>munmap</i>(2). The <i>clientdata</i>
-parameter is an opaque &lsquo;&lsquo;handle&rsquo;&rsquo;
-passed to the client-specified routines passed as parameters
-to <i>TIFFClientOpen</i>.</p>

-divided into multiple strips it looks as though the
-underlying file contains multiple separate strips. Finally,

-<p>The routines described here provide a high-level
-interface through which <small>TIFF</small> images may be
-read into memory. Images may be strip- or tile-based and
-have a variety of different characteristics: bits/sample,
-samples/pixel, photometric, etc. Decoding state is
-encapsulated in a <i>TIFFRGBAImage</i> structure making it
-possible to capture state for multiple images and quickly
-switch between them. The target raster format can be
-customized to a particular application&rsquo;s needs by
-installing custom routines that manipulate image data
-according to application requirements.</p>
-<!-- INDENTATION -->
-<p>The default usage for these routines is: check if an
-image can be processed using <i>TIFFRGBAImageOK</i>,
-construct a decoder state block using
-<i>TIFFRGBAImageBegin</i>, read and decode an image into a
-target raster using <i>TIFFRGBAImageGet</i>, and then
-release resources using <i>TIFFRGBAImageEnd</i>.
-<i>TIFFRGBAImageGet</i> can be called multiple times to
-decode an image using different state parameters. If
-multiple images are to be displayed and there is not enough
-space for each of the decoded rasters, multiple state blocks
-can be managed and then calls can be made to
-<i>TIFFRGBAImageGet</i> as needed to display an image.</p>
-<!-- INDENTATION -->
-<p>The generated raster is assumed to be an array of
-<i>width</i> times <i>height</i> 32-bit entries, where
-<i>width</i> must be less than or equal to the width of the
-image (<i>height</i> may be any non-zero size). If the
-raster dimensions are smaller than the image, the image data
-is cropped to the raster bounds. If the raster height is
-greater than that of the image, then the image data are
-placed in the lower part of the raster. (Note that the
-raster is assume to be organized such that the pixel at
-location (<i>x</i>,<i>y</i>) is
-<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the
-raster origin in the <b>lower-left</b> hand corner.)</p>
-<!-- INDENTATION -->
-<p>Raster pixels are 8-bit packed red, green, blue, alpha
-samples. The macros <i>TIFFGetR</i>, <i>TIFFGetG</i>,
-<i>TIFFGetB</i>, and <i>TIFFGetA</i> should be used to
-access individual samples. Images without Associated Alpha
-matting information have a constant Alpha of 1.0 (255).</p>
-<!-- INDENTATION -->
-<p><i>TIFFRGBAImageGet</i> converts non-8-bit images by
-scaling sample values. Palette, grayscale, bilevel,
-<small>CMYK</small> , and YCbCr images are converted to
-<small>RGB</small> transparently. Raster pixels are returned
-uncorrected by any colorimetry information present in the
-directory.</p>
-<!-- INDENTATION -->
-<p>The parameter <i>stopOnError</i> specifies how to act if
-an error is encountered while reading the image. If
-<i>stopOnError</i> is non-zero, then an error will terminate
-the operation; otherwise <i>TIFFRGBAImageGet</i> will
-continue processing data until all the possible data in the
-image have been requested.</p>

-<p>To use the core support for reading and processing
-<small>TIFF</small> images, but write the resulting raster
-data in a different format one need only override the
-&lsquo;&lsquo;<i>put methods</i>&rsquo;&rsquo; used to store
-raster data. These methods are are defined in the
-<i>TIFFRGBAImage</i> structure and initially setup by
-<i>TIFFRGBAImageBegin</i> to point to routines that pack
-raster data in the default <small>ABGR</small> pixel format.
-Two different routines are used according to the physical
-organization of the image data in the file:
-<i>PlanarConfiguration</i>=1 (packed samples), and
-<i>PlanarConfiguration</i>=2 (separated samples). Note that
-this mechanism can be used to transform the data before
-storing it in the raster. For example one can convert data
-to colormap indices for display on a colormap display.</p>

-<p>It is simple to display an image as it is being read into

-supporting alternate raster formats. Simply keep a reference
-to the default put methods setup by
-<i>TIFFRGBAImageBegin</i> and then invoke them before or
-after each display operation. For example, the
-<i>tiffgt</i>(1) utility uses the following put method to
-update the display as the raster is being filled:</p>

-<p><i>TIFFReadRGBAStrip</i> reads a single strip of a

-be an array of width times rowsperstrip 32-bit entries,
-where width is the width of the image (TIFFTAG_IMAGEWIDTH)
-and rowsperstrip is the maximum lines in a strip
-(TIFFTAG_ROWSPERSTRIP).</p>
-<!-- INDENTATION -->
-<p>The <i>row</i> value should be the row of the first row
-in the strip (strip * rowsperstrip, zero based).</p>
-<!-- INDENTATION -->
-<p>Note that the raster is assume to be organized such that
-the pixel at location (<i>x</i>,<i>y</i>) is
-<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the

-will begin at the beginning of the buffer.</p>

-
-<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFSetField</i></b>
-sets the value of a field or pseudo-tag in the current
-directory associated with the open <small>TIFF</small> file
-<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
-to control the operation of the <small>TIFF</small> library
-but whose value is not read or written to the underlying
-file.) To set the value of a field the file must have been
-previously opened for writing with <i>TIFFOpen</i>(3TIFF);
-pseudo-tags can be set whether the file was opened for
-reading or writing. The field is identified by <i>tag</i>,
-one of the values defined in the include file <b>tiff.h</b>
-(see also the table below). The actual value is specified
-using a variable argument list, as prescribed by the
-<i>stdarg</i>(3) interface (or, on some machines, the
-<i>varargs</i>(3) interface.)</p>
-
-
-<p style="margin-left:11%; margin-top: 1em"><i>TIFFVSetField</i>
-is functionally equivalent to <i>TIFFSetField</i> except
-that it takes a pointer to a variable argument list.
-<i>TIFFVSetField</i> is useful for writing routines that are
-layered on top of the functionality provided by
-<i>TIFFSetField</i>.</p>
-
-<p style="margin-left:11%; margin-top: 1em">The tags
-understood by <i>libtiff</i>, the number of parameter
-values, and the expected types for the parameter values are
-shown below. The data types are: <i>char*</i> is
-null-terminated string and corresponds to the
-<small>ASCII</small> data type; <i>uint16</i> is an unsigned
-16-bit value; <i>uint32</i> is an unsigned 32-bit value;
-<i>uint16*</i> is an array of unsigned 16-bit values.
-<i>void*</i> is an array of data values of unspecified
-type.</p>
-
-<p style="margin-left:11%; margin-top: 1em">Consult the
-<small>TIFF</small> specification for information on the
-meaning of each tag.</p>

-<p><i>TIFFWriteDirectory</i> will write the contents of the
-current directory to the file and setup to create a new
-subfile in the same file. Applications only need to call
-<i>TIFFWriteDirectory</i> when writing multiple subfiles to
-a single <small>TIFF</small> file. <i>TIFFWriteDirectory</i>
-is automatically called by <i>TIFFClose</i> and
-<i>TIFFFlush</i> to write a modified directory if the file
-is open for writing.</p>
-<!-- INDENTATION -->
-<p>The <i>TIFFRewriteDirectory</i> function operates
-similarly to <i>TIFFWriteDirectory,</i> but can be called
-with directories previously read or written that already
-have an established location in the file. It will rewrite
-the directory, but instead of place it at it&rsquo;s old
-location (as <i>TIFFWriteDirectory</i> would) it will place
-them at the end of the file, correcting the pointer from the
-preceeding directory or file header to point to it&rsquo;s
-new location. This is particularly important in cases where
-the size of the directory and pointed to data has grown, so
-it won&rsquo;t fit in the space available at the old
-location.</p>
-<!-- INDENTATION -->
-<p>The <i>TIFFCheckpointDirectory</i> writes the current
-state of the tiff directory into the file to make what is
-currently in the file readable. Unlike
-<i>TIFFWriteDirectory, TIFFCheckpointDirectory</i> does not
-free up the directory data structures in memory, so they can
-be updated (as strips/tiles are written) and written again.
-Reading such a partial file you will at worst get a tiff
-read error for the first strip/tile encountered that is
-incomplete, but you will at least get all the valid data in
-the file before that. When the file is complete, just use
-<i>TIFFWriteDirectory</i> as usual to finish it off
-cleanly.</p>

-<p><i>fax2ps</i> reads one or more <small>TIFF</small>

-PostScript on the standard output that is suitable for

-<!-- INDENTATION -->
-<p>By default, each page is scaled to reflect the image
-dimensions and resolutions stored in the file. The
-<b>&minus;x</b> and <b>&minus;y</b> options can be used to
-specify the horizontal and vertical image resolutions
-(lines/inch), respectively. If the <b>&minus;S</b> option is
-specified, each page is scaled to fill an output page. The
-default output page is 8.5 by 11 inches. Alternate page
-dimensions can be specified in inches with the
-<b>&minus;W</b> and <b>&minus;H</b> options.</p>
-<!-- INDENTATION -->
-<p>By default <i>fax2ps</i> generates PostScript for all

-select one or more pages from a multi-page document.</p>
-<!-- INDENTATION -->
-<p><i>fax2ps</i> generates a compressed form of PostScript
-that is optimized for sending pages of text to a PostScript
-printer attached to a host through a low-speed link (such as
-a serial line). Each output page is filled with white and
-then only the black areas are drawn. The PostScript
-specification of the black drawing operations is optimized
-by using a special font that encodes the move-draw
-operations required to fill the black regions on the page.
-This compression scheme typically results in a substantially
-reduced PostScript description, relative to the
-straightforward imaging of the page with a PostScript
-<i>image</i> operator. This algorithm can, however, be
-ineffective for continuous-tone and white-on-black images.
-For these images, it sometimes is more efficient to send the
-raster bitmap image directly; see <b>tiff2ps</b>(1).</p>

-<p><big><i>libtiff</i> is a library for reading and writing
-data files encoded with the <i>Tag Image File</i> format,
-Revision 6.0 (or revision 5.0 or revision 4.0). This file
-format is suitable for archiving multi-color and
-monochromatic image data.</big></p>
-<!-- INDENTATION -->
-<p><big>The library supports several compression algorithms,
-as indicated by the <i>Compression</i> field, including: no
-compression (1),</big> CCITT <big>1D Huffman compression
-(2),</big> CCITT <big>Group 3 Facsimile compression
-(3),</big> CCITT <big>Group 4 Facsimile compression (4),
-Lempel-Ziv &amp; Welch compression (5), baseline JPEG
-compression (7), word-aligned 1D Huffman compression
-(32771), and PackBits compression (32773). In addition,
-several nonstandard compression algorithms are supported:
-the 4-bit compression algorithm used by the
-<i>ThunderScan</i> program (32809) (decompression only),
-NeXT&rsquo;s 2-bit compression algorithm (32766)
-(decompression only), an experimental LZ-style algorithm
-known as Deflate (32946), and an experimental CIE LogLuv
-compression scheme designed for images with high dynamic
-range (32845 for LogL and 32845 for LogLuv). Directory
-information may be in either little- or big-endian byte
-order&minus;byte swapping is automatically done by the
-library. Data bit ordering may be either Most Significant
-Bit (</big> MSB <big>) to Least Significant Bit (</big> LSB
-<big>) or</big> LSB <big>to</big> MSB. <big>Finally, the
-library does not support files in which the
-<i>BitsPerSample</i>, <i>Compression</i>,
-<i>MinSampleValue</i>, or <i>MaxSampleValue</i> fields are
-defined differently on a per-sample basis (in Rev. 6.0 the
-<i>Compression</i> tag is not defined on a per-sample basis,
-so this is immaterial).</big></p>

-<p><big>Note that <i>tstrip_t</i>, <i>ttile_t</i>, and
-<i>tsize_t</i> are constrained to be no more than 32-bit
-quantities by 32-bit fields they are stored in in the</big>
-TIFF <big>image. Likewise <i>tsample_t</i> is limited by the
-16-bit field used to store the <i>SamplesPerPixel</i> tag.
-<i>tdir_t</i> constrains the maximum number of</big> IFDs
-<big>that may appear in an image and may be an arbitrary
-size (w/o penalty). <i>ttag_t</i> must be either int,
-unsigned int, pointer, or double because the library uses a
-varargs interface and</big> ANSI C <big>restricts the type
-of the parameter before an ellipsis to be a promoted type.
-<i>toff_t</i> is defined as int32 because TIFF file offsets
-are (unsigned) 32-bit quantities. A signed value is used
-because some interfaces return &minus;1 on error. Finally,
-note that user-specified data references are passed as
-opaque handles and only cast at the lowest layers where

-<p><i>tiff2pdf</i> opens a TIFF image and writes a PDF
-document to standard output.</p>
-<!-- INDENTATION -->
-<p>The program converts one TIFF file to one PDF file,
-including multiple page TIFF files, tiled TIFF files, black
-and white. grayscale, and color TIFF files that contain data
-of TIFF photometric interpretations of bilevel, grayscale,
-RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
-<i>libtiff</i> and PDF.</p>
-<!-- INDENTATION -->
-<p>If you have multiple TIFF files to convert into one PDF
-file then use <i>tiffcp</i> or other program to concatenate
-the files into a multiple page TIFF file. If the input TIFF
-file is of huge dimensions (greater than 10000 pixels height
-or width) convert the input image to a tiled TIFF if it is
-not already.</p>
-<!-- INDENTATION -->
-<p>The standard output is standard output. Set the output
-file name with the <b>&minus;o</b> <i>output.pdf</i>
-option.</p>
-<!-- INDENTATION -->
-<p>All black and white files are compressed into a single
-strip CCITT G4 Fax compressed PDF, unless tiled, where tiled
-black and white images are compressed into tiled CCITT G4
-Fax compressed PDF, <i>libtiff</i> CCITT support is
-assumed.</p>
-<!-- INDENTATION -->
-<p>Color and grayscale data can be compressed using either
-JPEG compression, ITU-T T.81, or Zip/Deflate LZ77
-compression. Set the compression type using the
-<b>&minus;j</b> or <b>&minus;z</b> options. JPEG compression
-support requires that <i>libtiff</i> be configured with JPEG
-support, and Zip/Deflate compression support requires that
-<i>libtiff</i> be configured with Zip support, in
-tiffconf.h. Use only one or the other of <b>&minus;j</b> and
-<b>&minus;z.</b></p>
-<!-- INDENTATION -->
-<p>If the input TIFF contains single strip CCITT G4 Fax
-compressed information, then that is written to the PDF file
-without transcoding, unless the options of no compression
-and no passthrough are set, <b>&minus;d</b> and
-<b>&minus;n.</b></p>
-<!-- INDENTATION -->
-<p>If the input TIFF contains JPEG or single strip
-Zip/Deflate compressed information, and they are configured,
-then that is written to the PDF file without transcoding,
-unless the options of no compression and no passthrough are
-set.</p>
-<!-- INDENTATION -->
-<p>The default page size upon which the TIFF image is placed
-is determined by the resolution and extent of the image
-data. Default values for the TIFF image resolution can be
-set using the <b>&minus;x</b> and <b>&minus;y</b> options.
-The page size can be set using the <b>&minus;p</b> option
-for paper size, or <b>&minus;w</b> and <b>&minus;l</b> for
-paper width and length, then each page of the TIFF image is
-centered on its page. The distance unit for default
-resolution and page width and length can be set by the
-<b>&minus;u</b> option, the default unit is inch.</p>
-<!-- INDENTATION -->
-<p>Various items of the output document information can be
-set with the <b>&minus;e</b>, <b>&minus;c</b>,
-<b>&minus;a</b>, <b>&minus;t</b>, <b>&minus;s</b>, and
-<b>&minus;k</b> options. Setting the argument of the option
-to &quot;&quot; for these tags causes the relevant document
-information field to be not written. Some of the document
-information values otherwise get their information from the
-input TIFF image, the software, author, document name, and
-image description.</p>

-<p><i>tiff2ps</i> reads <small>TIFF</small> images and
-writes PostScript or Encapsulated PostScript (EPS) on the
-standard output. By default, <i>tiff2ps</i> writes
-Encapsulated PostScript for the first image in the specified
-<small>TIFF</small> image file.</p>
-<!-- INDENTATION -->
-<p>By default, <i>tiff2ps</i> will generate PostScript that
-fills a printed area specified by the <small>TIFF</small>
-tags in the input file. If the file does not contain
-<i>XResolution</i> or <i>YResolution</i> tags, then the
-printed area is set according to the image dimensions. The
-<b>&minus;w</b> and <b>&minus;h</b> options (see below) can
-be used to set the dimensions of the printed area in inches;
-overriding any relevant <small>TIFF</small> tags.</p>
-<!-- INDENTATION -->
-<p>The PostScript generated for <small>RGB,</small> palette,
-and <small>CMYK</small> images uses the <i>colorimage</i>
-operator. The PostScript generated for greyscale and bilevel
-images uses the <i>image</i> operator. When the
-<i>colorimage</i> operator is used, PostScript code to
-emulate this operator on older PostScript printers is also
-generated. Note that this emulation code can be very
-slow.</p>

-<p><i>Tiff2rgba</i> converts a wide variety of TIFF images
-into an RGBA TIFF image. This includes the ability to
-translate different color spaces and photometric
-interpretation into RGBA, support for alpha blending, and
-translation of many different bit depths into a 32bit RGBA
-image.</p>
-<!-- INDENTATION -->
-<p>Internally this program is implemented using the
-<i>TIFFReadRGBAImage()</i> function, and it suffers any
-limitations of that image. This includes limited support for
-&gt; 8 BitsPerSample images, and flaws with some esoteric
-combinations of BitsPerSample, photometric interpretation,
-block organization and planar configuration.</p>
-<!-- INDENTATION -->
-<p>The generated images are stripped images with four
-samples per pixel (red, green, blue and alpha) or if the
-<b>&minus;n</b> flag is used, three samples per pixel (red,
-green, and blue). The resulting images are always planar
-configuration contiguous. For this reason, this program is a
-useful utility for transform exotic TIFF files into a form
-ingestible by almost any TIFF supporting software.</p>

-<p><i>tiffcrop</i> combines one or more files created
-according to the Tag Image File Format, Revision 6.0 into a
-single <small>TIFF</small> file. The output file may be
-compressed using a different algorithm than the input files.
-<i>tiffcrop</i> is most often used to extract portions of an
-image for processing with bar code recognizer or OCR
-software when that software cannot restrict the region of
-interest to a specific portion of the image or to improve
-efficiency when the regions of interest must be rotated.</p>
-<!-- INDENTATION -->
-<p>By default, <i>tiffcrop</i> will copy all the understood
-tags in a <small>TIFF</small> directory of an input file to
-the associated directory in the output file.</p>
-<!-- INDENTATION -->
-<p><i>tiffcrop</i> can be used to reorganize the storage
-characteristics of data in a file, and it will alter or

-Silicon Graphics has seen fit to allow us to give this work away. It

-The libtiff software was written by Sam Leffler while working for
-Silicon Graphics.<p>
-
-The LZW algorithm is derived from the compress program (the proper attribution
-is included in the source code). The Group 3 fax stuff originated as code
-from Jef Poskanzer, but has since been rewritten several times. The latest
-version uses an algorithm from Frank Cringle -- consult
-<TT>libtiff/mkg3states.c</TT> and <TT>libtiff/tif_fax3.h</TT> for further
-information. The JPEG support was written by Tom Lane and is dependent on the
-excellent work of Tom Lane and the Independent JPEG Group (IJG) who distribute
-their work under friendly licensing similar to this software. Joris Van Damme
-implemented the robust Old JPEG decoder (as included in libtiff since version
-3.9.0, there was another Old JPEG module in older releases, which was
-incomplete and unsuitable for many existing images of that format). JBIG
-module was written by Lee Howard and depends on JBIG library from the Markus
-Kuhn. Many other people have by now helped with bug fixes and code; a few of
-the more persistent contributors have been:

-<p>This software distribution comes with a small collection of
-programs for converting non-TIFF format images to TIFF and for
-manipulating and interrogating the contents of TIFF images. Several
-of these tools are useful in their own right. Many of them however
-are more intended to serve as programming examples for using the
-TIFF library.</p>
-<h3>Device-dependent Programs</h3>
-There are two device-dependent programs that serve as simple
-examples for writing programs to display and save TIFF images.

-<LI>various typos and fixes were made in configure for the the
- library-only build support (this and other configure fixes from
- Richard Mlynarik <A HREF=mailto:mly@adoc.xerox.com>&lt;mly@adoc.xerox.com&gt;</A>)
-<LI>bugs were fixed in the handling of pathnames supplied for external

-<LI>the handling of <TT>SETMAKE</TT> is now done properly
-<LI>the default prototype function declaration for <TT>pow</TT> was corrected

-<LI>complaints about unknown and/or unsupported codecs have been
- delayed until they are invoked; this permits applications to open
- images and look at tags even if the image data is compressed with
- an unknown/unsupported compression scheme
-<LI>bugs in handling unknown tags have been corrected; applications
- that use multiple codecs, each with codec-specific tags, no longer
- generate confusing error messages
-<LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed
- (this problem caused core dumps in the <TT>tiffcp</TT> program)
-<LI>pseudo-tags are now treated specially; they are always considered
- to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors).

- through a mode parameter supplied when opening a file (``C'' to
- enable strip chopping and ``c'' to disable)
-<LI>two bugs were fixed in the writing of opposite-endian byte-order
- files
-<LI>support was added for three new fax-related tags registered to
- SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress
-<LI>the bit order of image data read and written can now be controlled
- on a per-file basis through a mode parameter supplied when opening

-<p>
-The ChangeLog will follow, but please note the most important change:
-LZW compression has been removed.
-<p>
-Unisys has the patent on LZW compression and have been very active in
-their enforcement of late, demanding payments of $5000 or more from
-websites using unlicensed software to create GIF's. They could well
-do the same do persons using libtiff to create LZW compressed TIFF
-images.
-<p>
-From <A HREF=http://burnallgifs.org>Burn All GIF's Day</a>:
-<br>
-<em>The catch is that it appears to be difficult or impossible to get a
-Unisys license to use LZW in free software that complies with the Open
-Source Definition</em>
-<P>
-Unfortunatly, the removal of LZW compression means that saved image size has
-grown dramatically. Without a change in the TIFF spec to support
-another lossless compression format, this is unavoidable.
-<P>
-The library can use zip for lossless compression, but as this is not
-part of the spec, TIFFs using zip compression may not work with other
-software
-<P>
-We will be making a patch available that will contain the LZW
-compression code for users who have either obtained a license from
-Unisys or are willing to risk it.
-<p>
-LZW decompression is unchanged.

- <LI> Added html for TIFFWriteTile.3t man page.
-
- <LI> Added some changes to tif_write.c to support rewriting existing
- fixed sized tiles and strips. Code mods disabled by default, only
- enabled if REWRITE_HACK is defined for now.
-
- <LI> Added TIFFWriteTile.3t man page.
-
- <LI> Added notes on use of makefile.vc in build.html, and fixed
- email subscription address.
-
- <LI> Fixed apocalypse-inducing y2k bug in contrib/ras/ras2tiff.c
-
- <LI> Did some casts cleaning up to reduce compiler warnings in tif_fax3.c,
- from Bruce Carmeron <cameron@petris.com> -- modifications of
- changes made by Frank (sun cc still complained on cast).
-
- <LI> fixed various VC++ warnings as suggested by Gilles Vollant

-
- <LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
- as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
- from vandrove@vc.cvut.cz.
-
- <LI> Modified tif_packbits.c decoding to avoid overrunning the
- output buffer, and to issue a warning if data needs to be
- discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
-
- <LI> Modified TIFFClientOpen() to emit an error on an attempt to
- open a comperessed file for update (O_RDWR/r+) access. This is
- because the compressor/decompressor code gets very confused when
- the mode is O_RDWR, assuming this means writing only. See
- bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
-
- <LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
- of EXPAND1D() as per bug 11 (from Roman).
-
- <LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
- cygwin compatibility.
-
- <LI> Applied patch from Roman Shpount to tif_fax3.c. This seems to
- be a proper fix to the buffer sizing problem. See
- http://bugzilla.remotesensing.org/show_bug.cgi?id=11
-
- <LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
- downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10
- Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
- bug and proving the patch.
-
- <LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
- we are done access data thanks to bug report from:
- Michael Eckstein <eckstein@gepro.cz>.
-
- <LI> tif_open.c: Don't set MMAP for O_RDWR files.
-
- <LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
- so that files opened for update can be strip chopped too.
-
- <LI> tif_read.c: fixed up bug with files missing rowsperstrip and
- the strips per separation fix done a few weeks ago.
-
- <LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
- SAMPLEFORMAT_COMPLEXINT.
-
- <LI> index.html, bugs.html: added bugzilla info.
-
- <LI> tif_read.c: fix subtle bug with determining the number of
- rows for strips that are the last strip in a separation but
- not the last strip of all in TIFFReadEncodedStrip().
-
- <LI> Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
- Peter Skarpetis <peters@serendipity-software.com.au>
-
- <LI> Modified tiffio.h logic with regard to including windows.h. It
- won't include it when building with __CYGWIN__.
-
- <LI> README: update to mention www.libtiff.org, don't list Sam's old
- email address.
-
- <LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
- one tile/strip images with an offset, and byte count of zero. These
- could be "unpopulated" images.

-<UL>
-<li> libtiff/libtiff.def: Brent Roman submitted new version adding
-serveral missing entry points. Also add a few other entry points
-later.
-
-<li> configure, Makefile.in, etc: added support for OPTIMIZER being
- set from config.site.
-<li> config.guess: updated wholesale to an FSF version apparently
- from 1998 (as opposed to 1994). This is mainly inspired by
- providing for MacOS X support.
-
-<li> configure/config.site: modified to check if -lm is needed for
- MACHDEPLIBS if not supplied by config.site. Needed for Darwin.
-<li> libtiff/tiff.h: Applied hac to try and resolve the problem
- with the inttypes.h include file on AIX. (Bug 39)
-
-<li> configure, *Makefile.in: Various changes to improve configuration
- for HP/UX specifically, and also in general. (Bug 40) They include:
-<ul>
- <li> Try to handle /usr/bin/sh instead of /bin/sh where necessary.
- <li> Upgrade to HP/UX 10.x+ compiler, linker and dso options.
- <li> Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP
- <li> Use -${MAKEFLAGS} in sub makes from makefiles.
- <li> Fixed SCRIPT_SH/SHELL handling.
-</ul>
-<li> configure: Changes for DSO generation on AIX provided by
- John Marquart <jomarqua@indiana.edu>.
-
-<li> configure, libtiff/Makefile.in: Modified to build DSOs properly
- on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and
- Keisuke Fujii (fujiik@jlcuxf.kek.jp).
-
-<li> configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61.
-
-<li> Makefile.in: added DESTDIR support as per bug 60.
-
-<li> libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H
- has been included.
-<li> man/Makefile.in: add TIFFClientOpen link as per debian submitted
- bug 66.
-<li> libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@
- in two places.

-
-<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
-
-
-<UL>
-<li> tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
- whether we are encoding or decoding. This is to ensure graceful
- recovery if TIFFClientOpen() discovers an attempt to open a compressed
- file for "r+" access, and subsequently close it, as it resets the
- tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
- compressor's concept of whether it is in encode or decode mode.
-<li> tif_luv.c/tiff.h/tiffio.h:
- New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
- (greg@shutterfly.com). He writes:
-
-<ol>
- <li> I improved the gamut-mapping function in tif_luv.c for imaginary
- colors, because some images were being super-saturated on the input
- side and this resulted in some strange color shifts in the output.
-
- <li> I added a psuedotag in tiff.h to control random dithering during
- LogLuv encoding. This is turned off by default for 32-bit LogLuv and
- on for 24-bit LogLuv output. Dithering improves the average color
- accuracy over the image.
-
- <li> I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
- tiffio.h, to expose internal routines for converting between LogLuv and
- XYZ coordinates. This is helpful for writing more efficient,
- specialized conversion routines, especially for reading LogLuv files.
-</ol>
-
-<li> libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
-
-<li> Added TIFFTAG_COPYRIGHT support.
-<li> tif_getimage.c: Added support for 16bit minisblack/miniswhite
- images in RGBA interface.
-<li> libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per
- bug 44.
-<li> libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
- case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43.
-
-<li> libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for
- TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to
- force use of uint32 counts instead of short counts.
-
-<li> libtiff/tif_dirinfo.c: moved pixar and copyright flags to
- ensure everything is in order.
-
-<li> Integrated experimental OJPEG support from Scott Marovich of HP.
-
-<li> libtiff/tif_open.c: Seek back to zero after failed read,
- before writing header.
-
-<li> libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__
- when checking for 64 bit architectures as per bugzilla bug 67.
-<li> libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy()
- in TIFFReadRGBATile() to avoid issues in cases of overlapping
- buffers. See Bug 69 in Bugzilla.
-<li> libtiff/tif_getimage.c: Don't complain for CMYK (separated)
- images with more than four samples per pixel as per bug 73.
-
-<li> libtiff/tif_getimage.c: relax handling of contig case where
-there are extra samples that are supposed to be ignored as per bug 75. This
-should now work for 8bit greyscale or palletted images.
-
-<li> libtiff/tif_packbits.c: fixed memory overrun error as per bug 77.
-
-<li> libtiff/tif_getimage.c: Fixed problem with reading strips or
-tiles that don't start on a tile boundary. Fix contributed by
-Josep Vallverdu (from HP), and further described in bug 47.
-
-<li> libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to
- always use the "safe" version, even if there is a very slight
- cost in performance as per bug 54.
-<li> libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an
- error about LZW not being available.
-
-<li> libtiff/tif_dir.c: propagate failure to initialize compression
- back from TIFFSetField() as an error status, so applications can
- detect failure.
-
-<li> libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78.
-
-<li> libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function.
-Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory.
-
-<li> libtiff/tiff.h: I have created COMPRESSION_CCITT_T4,
- COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases
- in keeping with TIFF 6.0 standard in tiff.h as per bug 83.
-
-<li> Added PHOTOMETRIC_ITULAB as per bug 90.

-<li> Brent Roman contributed updated tiffcp utility (and tiffcp.1)
- with support for extracting subimages with the ,n syntax, and also
- adding the -b bias removal flag.
-<li> tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
- Bruce A. Mallett, including a faster encoder, fixes for level
- 2 PostScript, and support for the imagemask operator.
-<li> fax2ps.c: Helge (libtiff at oldach.net) submitted fix
-that corrects behaviour for non-Letter paper
-sizes. (Bug 35) It fixes two problems:
-<br>
- Without scaling (-S) the fax is now centered on the page size specified
- with -H and/or -W. Before, fax2ps was using an obscure and practially
- useless algorithm to allocate the image relative to Letter sized paper
- which sometime sled to useless whitespace on the paper, while at the
- same time cutting of the faxes printable area at the opposite border.
-<br>
-
- Second, scaling now preserves aspect ratio, which makes unusual faxes
- (in particular short ones) print properly.
-
-<li> thumbnail.c: changed default output compression
- to packbits from LZW since LZW isn't generally available.
-<li> tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added
-a man page for tiff2rgba.
-
-<li> tiffcmp.c: Fixed multi samples per pixel support for ContigCompare
-as per bug 53.
-Updated bug section of tiffcmp.1 to note tiled file issues.
-
-<li> libtiff/tif_getimage.c: Fixed so that failure is properly
- reported by gtTileContig, gtStripContig, gtTileSeparate and
- gtStripSeparate as per bug 51.

-<h3>Custom Tag Support</h3>
-
-The approach to extending libtiff with custom tags has changed radically.
-Previously, all internally supported TIFF tags had a place in the
-private TIFFDirectory structure within libtiff to hold the values (if read),
-and a "field number" (ie. FIELD_SUBFILETYPE) used to identify that tag.
-However, every time a new tag was added to the core, the size of the
-TIFFDirectory structure would changing, breaking any dynamically linked
-software that used the private data structures.<p>
-
-Also, any tag not recognised
-by libtiff would not be read and accessable to applications without some
-fairly complicated work on the applications part to pre-register the tags
-as exemplified by the support for "Geo"TIFF tags by libgeotiff layered on
-libtiff. <p>
-
-Amoung other things this approach required the extension code
-to access the private libtiff structures ... which made the higher level
-non-libtiff code be locked into a specific version of libtiff at compile time.
-This caused no end of bug reports!<p>
-
-The new approach is for libtiff to read all tags from TIFF files. Those that
-aren't recognised as "core tags" (those having an associated FIELD_ value,
-and place for storage in the TIFFDirectory structure) are now read into a
-dynamic list of extra tags (td_customValues in TIFFDirectory). When a new
-tag code is encountered for the first time in a given TIFF file, a new
-anonymous tag definition is created for the tag in the tag definition list.
-The type, and some other metadata is worked out from the instance encountered.
-These fields are known as "custom tags". <p>
-
-Custom tags can be set and fetched normally using TIFFSetField() and
-TIFFGetField(), and appear pretty much like normal tags to application code.
-However, they have no impact on internal libtiff processing (such as
-compression). Some utilities, such as tiffcp will now copy these custom
-tags to the new output files. <p>
-
-As well as the internal work with custom tags, new C API entry points
-were added so that extension libraries, such as libgeotiff, could
-define new tags more easily without accessing internal data structures.
-Because tag handling of extension tags is done via the "custom fields"
-mechanism as well, the definition provided externally mostly serves to provide
-a meaningful name for the tag.
-
-The addition of "custom tags" and the altered approach to extending libtiff
-with externally defined tags is the primary reason for the shift to the
-3.6.x version number from 3.5.x.<p>

-
-<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
-
-<UL>
-
-<li> libtiff/tif_getimage.c: New function <A

-implemented to retrieve raster array with user-specified origin position.
-
-<li> libtiff/tif_fax3.c: Fix wrong line numbering.
-
-<li> libtiff/tif_dirread.c: Check field counter against number of fields.
-
-<li> Store a list of opened IFD to prevent directory looping.
-
-<li> libtiff/tif_jpeg.c: modified segment_height calculation to always
-be a full height tile for tiled images. Also changed error to just
-be a warning.
-
-<li> libtiff/tif_lzw.c: fixed so that decoder state isn't allocated till
-LZWSetupDecode(). Needed to read LZW files in "r+" mode.
-
-<li> libtiff/tif_dir.c: fixed up the tif_postdecode settings responsible
-for byte swapping complex image data.
-
-<li> libtiff/tif_open.c: Removed error if opening a compressed file
-in update mode bug (198).
-
-<li> libtiff/tif_write.c: TIFFWriteCheck() now fails if the image is
-a pre-existing compressed image. That is, image writing to pre-existing
-compressed images is not allowed.
-
-<li> html/man/*.html: Web pages regenerated from man pages.
-
-<li> libtiff/tif_jpeg.c: Hack to ensure that "boolean" is defined properly
-on Windows so as to avoid the structure size mismatch error from libjpeg
-(bug 188).
-
-<li> libtiff/tiff.h: #ifdef USING_VISUALAGE around previous Visual Age
-AIX porting hack as it screwed up gcc. (bug 39)
-
-<li> libtiff/tiff.h: added COMPRESSION_JP2000 (34712) for LEAD tools
-custom compression.
-
-<li> libtiff/tif_dirread.c: Another fix for the fetching SBYTE arrays
-by the TIFFFetchByteArray() function. (bug 52)
-
-<li> libtiff/tif_dirread.c: Expand v[2] to v[4] in TIFFFetchShortPair()
-as per bug 196.

-JPEGDecode() as per bug 129.
-
-<li> libtiff/tif_read.c, libtiff/tif_write.c: TIFFReadScanline() and

-
-<li> libtiff/tif_open.c: Pointers to custom procedures
-in TIFFClientOpen() are checked to be not NULL-pointers.
-
-<li> libtiff/tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat
-replaced by warnings. Now libtiff should read corrupted LZW-compressed
-files by skipping bad strips as per bug 100.
-
-<li> libtiff/: tif_dirwrite.c, tif_write.c, tiffio.h:
-<a href=./man/TIFFWriteDirectory.3t.html>TIFFCheckpointDirectory()</a>
-routine added as per bug 124. The
-<a href=./man/TIFFWriteDirectory.3t.html>TIFFWriteDirectory</a>
-man page discusses this new function as well as the related
-<a href=./man/TIFFWriteDirectory.3t.html>TIFFRewriteDirectory()</a>.
-
-<li> libtiff/: tif_codec.c, tif_compress.c, tiffiop.h, tif_getimage.c:
-Introduced
-additional members tif->tif_decodestatus and tif->tif_encodestatus
-for correct handling of unconfigured codecs (we should not try to read
-data or to define data size without correct codecs). See bug 119.
-
-<li> tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func as
-per bug 111.
-
-<li> libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
-tif_dirwrite.c: Dwight Kelly added get/put code for new tag XMLPACKET as
-defined in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0
-spec INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes:
-CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and

-use TIFFRGBAImageOK before reading a per bug 110.
-
-<li> libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
-tif_dirwrite.c: Added routine
-<a href=./man/TIFFDataWidth.3t.html>TIFFDataWidth</a> for determining
-TIFFDataType sizes instead of working with tiffDataWidth array
-directly as per bug 109.
-
-<li>libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to
-read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION,

-<li> libtiff/{tiff.h,tif_fax3.c}: Add support for __arch64__ as per bug 94.
-
-<li> libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the
-decodestrip function returns anything not greater than zero as per bug 97.
-
-<li> libtiff/tif_jpeg.c: fixed computation of segment_width for
-tiles files to avoid error about it not matching the
-cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile
-size.") for ITIFF files. Apparently the problem was incorporated since
-3.5.5, presumably during the OJPEG/JPEG work recently.
-
-<li> libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
-(defined in tiffconf.h - 1 by default) then the RGBA interface
-will assume that a fourth extra sample is ASSOCALPHA if the
-EXTRASAMPLE value isn't set for it. This changes the behaviour of
-the library, but makes it work better with RGBA files produced by
-lots of applications that don't mark the alpha values properly.
-As per bugs 93 and 65.
-
-<li> libtiff/tif_jpeg.c: allow jpeg data stream sampling values to
-override those from tiff directory. This makes this work with
-ImageGear generated files.

-<li> tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as
-it was done in 3.6.0).
-
-<li> libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype,
-intruduced in "Adobe PageMaker TIFF Technical Notes".
-
-<li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space
-conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage
-interface. YCbCr to RGB conversion code also moved there and now has
-<a href="./man/TIFFcolor.3t.html">publicly available interface</a>. These
-routines currently used in TIFFRGBAImage interface only and not supported in
-other libtiff tools yet. So if you want, for example, to convert CIE Lab image
-into PostScript file you should do it in two steps: chnge colorspace to RGB
-using <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then process
-it with the <a href="./man/tiff2ps.1.html">tiff2ps</a>.
-
-<li> libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the
-planarconfig_contig case in TIFFComputeTile() as per bug 387
-
-<li> libtiff/tiffiop.h: New macros: TIFFmax and TIFFmin.
-
-<li> libtiff/{tiffio.h, tif_strip.c}: Added TIFFRawStripSize() function
-as suggested by Chris Hanson.
-
-<li> libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update mode
-as per bug 424.

- non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
-
- <li> tif_getimage.c: Revision of all RGB(A) put routines:
- <ul>
- <li> Conversion of unassociated alpha to associated alpha
- now done with more performant LUT, and calculation more
- correct.
- <li> Conversion of 16bit data to 8bit data now done with
- more performant LUT, and calculation more correct
- <li> Bugfix of handling of 16bit RGB with unassociated alpha
- </ul>
-
- <li> tif_ojpeg.c: totally new implementation

- <li> tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling
- of OJPEG images in favor of tif_getimage.c native handling of
- YCbCr and desubsampling.
-
- <li> tif_jpeg.c: JPEGVSetField() so that altering the photometric
- interpretation causes the "upsampled" flag to be recomputed. Fixes
- peculiar bug where photometric flag had to be set before jpegcolormode
- flag.

-
-BigTIFF support changes:
-
-<UL>
-
- <LI>The options parameter in the TIFFOpen and TIFFClientOpen funcs has
- been extended. When creating new files, you can add option '4' to
- specify you want to create a ClassicTIFF file, though that is the
- default and the option is not strictly necessary. (As such, old
- calling code will continue to function and create ClassicTIFF files.)
- Or you can add option '8' to specify you want to create a BigTIFF file
- instead. This new option is also reflected in some of the tools we
- already upgraded. For instance, you can use the -8 option on tiffcp to
- have tiffcp produce BigTIFF files instead of the default ClassicTIFF.
- (Whilst on additional option is provided for version selection when
- creating new files, no such option is necessary when reading TIFF
- files. LibTiff reads ClassicTIFF and BigTIFF both, and the application
- does not need to be aware which TIFF version an opened file is.)
-
- <LI>Although the tag count in BigTIFF is 64bit, we restricted the
- count in the implementation to a much more reasonable size. This is
- necessary in current implementation, because all tag data gets read
- automatically in the IFD reading stage, so if there's half a dozen
- private tags with multiple gigabytes of data that causes considerable
- overhead even if the application level is never interested in these
- tags. Our choice to ignore tags with data longer then a certain sanity
- value is much needed as things stand. We also recommend to step away
- from writing tiles that are 8 kilobyte in their uncompressed form, or
- writing single-line strips, in really big files, resulting in mega's
- of tiles or strips. It's much more efficient to choose bigger tile or
- strip sizes, up to several megabyte if needed, and have a few kilo of
- tiles or strips instead.
-
- <LI>Although it's rare, some application code does directly access
- file offsets. Some of these are automatically upgraded because they
- used the toff_t type, others need to be aware that the datatype
- changed and need to start using toff_t or uint64. This impacts access
- to tags like the EXIF IFD tag, for example, or the SubIfds tag, or to
- StripOffsets or TileOffsets, the return type of functions like
- TIFFCurrentDirOffset, and a parameter type to functions like
- TIFFSetSubDirectory.
-
- <LI>Although it's rare, some application code does use structures
- like TIFFHeader or TIFFDirEntry that used to be an exact binary
- representation of TIFF structures. These need to change. The old
- TIFFHeader structure is replaced by the new TIFFHeaderClassic,
- TIFFHeaderBig, and TIFFHeaderCommon structures that are an exact
- binary representation of the ClassicTIFF and BigTIFF header, and of
- the part that is common to both. There is no new equivalent for the
- old TIFFDirEntry structure (or more precisely, there is still a
- TIFFDirEntry structure, but it is changed, moved to library-private
- definition, and no longer an exact binary representation of the tag
- structure of either TIFF version).
-
- <LI>Sizer functions, like TIFFTileSize or TIFFScanlineSize and the
- like, return a tmsize_t value (tmsize_t is defined as int32 on 32bit
- machines, and int64 on 64bit machines, and as such it is meant to
- represent signed memory sizes). This is because we figure 98% of the
- calling code uses the return value as sizes in allocations and the
- like. So, any overflow that is theoretically possible with BigTIFF
- when LibTiff is running on a 32bit system, is best detected inside the
- sizer functions and it is best to return a type that makes sense as a
- memory size. If your calling code is the exception and is interested
- in actual file size, you best use the newer TIFFTileSize64 or
- TIFFScanlineSize64 function that returns an uint64 type.
-
- <LI>These TIFF tags require a 64-bit type as an argument in
- libtiff 4.0.0:
- <UL>
- <LI> TIFFTAG_FREEBYTECOUNTS
- <LI> TIFFTAG_FREEOFFSETS
- <LI> TIFFTAG_STRIPBYTECOUNTS
- <LI> TIFFTAG_STRIPOFFSETS
- <LI> TIFFTAG_TILEBYTECOUNTS
- <LI> TIFFTAG_TILEOFFSETS
- </UL>
-
-</UL>
-
-Other important backward incompatible changes in the public API:
-
-<UL>
- <LI> TIFFRewriteField() renamed into _TIFFRewriteField() and moved out
- from the public interface (from tiffio.h to tiffiop.h). Type of its
- 'count' parameter changed from uint32 to tmsize_t.
-
- <LI> TIFFMergeFieldInfo() returns non-void result now. It returns 0
- if successful and -1 if failed. Though this is now obsoleted function
- and should not be used in new programs. Use the new tag extension
- scheme instead.
-
- <LI> TIFFFieldWithTag() and TIFFFieldWithName() functions now return
- pointer to TIFFField constant object instead of TIFFFieldInfo.
-
- <LI> TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration
- have been removed. They was unused and never been used properly.
- Should be unneeded for high-level applications.
-
- <LI> TIFFTagValue structure removed from the public tiffio.h
- to private tif_dir.h and not accessible anymore. It should be unneeded
- for high-level applications.

-
- <LI>Updated autotools: Autoconf 2.68, Automake 1.11.1, libtool
- 2.4.
-
- <LI>Enabled support for Automake silent build rules
- (--enable-silent-rules or 'make V=0')
-
- <LI>Enabled support for Automake colorized and parallel tests.
-
- <LI>Added detection of 64-bit integer types since libtiff 4.0
- requires use of 64-bit signed and unsigned integer types.
-
- <LI>Libtiff now provides a more comprehensive test suite with
- over 72 tests, which may be executed on Unix-like systems, or
- under Microsoft Windows using MinGW/MSYS or Cygwin.
-
- <LI>--disable-lzma configure option to disable use of liblzma.
-
- <LI>--enable-defer-strile-load configure option to enable
- experimental deferred strip/tile offset/size loading. May
- cause some extremely sophisticated uses of libtiff to fail.
-
- <LI>--enable-chunky-strip-read configure option to enable
- experimental enable reading large strips in chunks in
- TIFFReadScanline().
-
- <LI>Now always uses WIN32 native I/O functions for Microsoft
- Windows except for under Cygwin.
-
- <LI>Now provides a pkg-config support file (libtiff-4.pc).

-
- <LI>Patches/fixes made to stable libtiff (v3.9.X) are also
- applied to 4.0.0. There are too many to list here. See the
- distribution ChangeLog for a detailed change list.
-
- <LI>There is considerable change in some files like
- tif_dirread and tif_dirwrite. These changes don't impact
- backwards compatibility, they are mostly a clean rewrite that
- does allow BigTIFF support as well as somewhat more robust
- reading of the unexpected already and will also serve future
- API extension but does not impact current API or functionality
- in a negative way that you need to know about.
-
- <LI>Although there is still a functional definition for types
- like toff_t (file offset), tstrip_t (strip index number), etc,
- we recommend against using these in newer code. We have
- learned that it is next to impossible to use these
- consistently and make real abstraction of the binary format of
- these types. Instead, at a certain level we always end up
- doing casts anyway, and taking the exact binary format into
- account, so these types are nothing but dangerously misleading
- and obfuscating. You do not need to update calling code that
- uses them, as 99.9% of such code will continue to work. But we
- recommend against using them in newer calling code, and we
- started replacing them with binary clear types like uint16,
- uint32 and such in the library.
-
- <LI>We do use and will continue to use one functional type
- that is an exception to the above rule, being tmsize_t. This
- is a signed memory size type, i.e. it is int32 on 32bit
- machines, or int64 on 64bit machines.
-
- <LI>Optionally support LZMA compression via TIFF tag 34925.
- Tiffcp supports compression levels similar to "-c lzma:p1" or
- "-c zip:p9 for setting the LZMA compression parameters.
-
- <LI>Optionally defer the load of strip/tile offset and size
- tags for optimized scanning of directories. Enabled with the
- --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
- #define in tif_config.h).
-
- <LI>Optionally enable experimental support for reading big
- strips in chunks. Enabled with the --enable-chunky-strip-read
- configure option.

-// brought in as LSB.
-// To avoid reading the fresh bits one by one (slow), we cache a few of them

+// cache BITS of them ahead. The total of (BITS + 8) bits must fit into a
+// natural register (with type bit_t). To fetch BITS bits from bitstream we
+// use a type lbit_t.
//
-// Example, for BITS=16: here is the content of value_ for both strategies:
-//
-// !USE_RIGHT_JUSTIFY || USE_RIGHT_JUSTIFY

-// ||
-// After calling VP8Shift(), where we need to shift away two zeros:
-// [........vvvvvvvvBBBBBBBBBBB00000]LSB || [.............vvvvvvvvBBBBBBBBBBB]
-// ||
-// Just before we need to call VP8LoadNewBytes(), the situation is:
-// [........vvvvvv000000000000000000]LSB || [..........................vvvvvv]
-// ||
-// And just after calling VP8LoadNewBytes():
