+libjpeg-turbo Licenses
+======================
+
+libjpeg-turbo is covered by three compatible BSD-style open source licenses:
+
+- The IJG (Independent JPEG Group) License, which is listed in
+ [README.ijg](README.ijg)
+
+ This license applies to the libjpeg API library and associated programs
+ (any code inherited from libjpeg, and any modifications to that code.)
+
+- The Modified (3-clause) BSD License, which is listed below
+
+ This license covers the TurboJPEG API library and associated programs.
+
+- The zlib License, which is listed below
+
+ This license is a subset of the other two, and it covers the libjpeg-turbo
+ SIMD extensions.
+
+
+Complying with the libjpeg-turbo Licenses
+=========================================
+
+This section provides a roll-up of the libjpeg-turbo licensing terms, to the
+best of our understanding.
+
+1. If you are distributing a modified version of the libjpeg-turbo source,
+ then:
+
+ 1. You cannot alter or remove any existing copyright or license notices
+ from the source.
+
+ **Origin**
+ - Clause 1 of the IJG License
+ - Clause 1 of the Modified BSD License
+ - Clauses 1 and 3 of the zlib License
+
+ 2. You must add your own copyright notice to the header of each source
+ file you modified, so others can tell that you modified that file (if
+ there is not an existing copyright header in that file, then you can
+ simply add a notice stating that you modified the file.)
+
+ **Origin**
+ - Clause 1 of the IJG License
+ - Clause 2 of the zlib License
+
+ 3. You must include the IJG README file, and you must not alter any of the
+ copyright or license text in that file.
+
+ **Origin**
+ - Clause 1 of the IJG License
+
+2. If you are distributing only libjpeg-turbo binaries without the source, or
+ if you are distributing an application that statically links with
+ libjpeg-turbo, then:
+
+ 1. Your product documentation must include a message stating:
+
+ This software is based in part on the work of the Independent JPEG
+ Group.
+
+ **Origin**
+ - Clause 2 of the IJG license
+
+ 2. If your binary distribution includes or uses the TurboJPEG API, then
+ your product documentation must include the text of the Modified BSD
+ License.
+
+ **Origin**
+ - Clause 2 of the Modified BSD License
+
+3. You cannot use the name of the IJG or The libjpeg-turbo Project or the
+ contributors thereof in advertising, publicity, etc.
+
+ **Origin**
+ - IJG License
+ - Clause 3 of the Modified BSD License
+
+4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
+ free of defects, nor do we accept any liability for undesirable
+ consequences resulting from your use of the software.
+
+ **Origin**
+ - IJG License
+ - Modified BSD License
+ - zlib License
+
+

-IJG JPEG LIBRARY: CODING RULES
-
-Copyright (C) 1991-1996, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Since numerous people will be contributing code and bug fixes, it's important
-to establish a common coding style. The goal of using similar coding styles
-is much more important than the details of just what that style is.
-
-In general we follow the recommendations of "Recommended C Style and Coding
-Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
-Brader). This document is available in the IJG FTP archive (see
-jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
-
-Block comments should be laid out thusly:
-
-/*
- * Block comments in this style.
- */
-
-We indent statements in K&R style, e.g.,
- if (test) {
- then-part;
- } else {
- else-part;
- }
-with two spaces per indentation level. (This indentation convention is
-handled automatically by GNU Emacs and many other text editors.)
-
-Multi-word names should be written in lower case with underscores, e.g.,
-multi_word_name (not multiWordName). Preprocessor symbols and enum constants
-are similar but upper case (MULTI_WORD_NAME). Names should be unique within
-the first fifteen characters. (On some older systems, global names must be
-unique within six characters. We accommodate this without cluttering the
-source code by using macros to substitute shorter names.)
-
-We use function prototypes everywhere; we rely on automatic source code
-transformation to feed prototype-less C compilers. Transformation is done
-by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
-ansi2knr is not very bright, so it imposes a format requirement on function
-declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions
-should be written in the following style:
-
-LOCAL(int *)
-function_name (int a, char *b)
-{
- code...
-}
-
-Note that each function definition must begin with GLOBAL(type), LOCAL(type),
-or METHODDEF(type). These macros expand to "static type" or just "type" as
-appropriate. They provide a readable indication of the routine's usage and
-can readily be changed for special needs. (For instance, special linkage
-keywords can be inserted for use in Windows DLLs.)
-
-ansi2knr does not transform method declarations (function pointers in
-structs). We handle these with a macro JMETHOD, defined as
- #ifdef HAVE_PROTOTYPES
- #define JMETHOD(type,methodname,arglist) type (*methodname) arglist
- #else
- #define JMETHOD(type,methodname,arglist) type (*methodname) ()
- #endif
-which is used like this:
- struct function_pointers {
- JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
- JMETHOD(void, term_entropy_encoder, (void));
- };
-Note the set of parentheses surrounding the parameter list.
-
-A similar solution is used for forward and external function declarations
-(see the EXTERN and JPP macros).
-
-If the code is to work on non-ANSI compilers, we cannot rely on a prototype
-declaration to coerce actual parameters into the right types. Therefore, use
-explicit casts on actual parameters whenever the actual parameter type is not
-identical to the formal parameter. Beware of implicit conversions to "int".
-
-It seems there are some non-ANSI compilers in which the sizeof() operator
-is defined to return int, yet size_t is defined as long. Needless to say,
-this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(),
-so that the result is guaranteed to be of type size_t.
-
-
-The JPEG library is intended to be used within larger programs. Furthermore,
-we want it to be reentrant so that it can be used by applications that process
-multiple images concurrently. The following rules support these requirements:
-
-1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
-pass these through the common routines provided.
-
-2. Minimize global namespace pollution. Functions should be declared static
-wherever possible. (Note that our method-based calling conventions help this
-a lot: in many modules only the initialization function will ever need to be
-called directly, so only that function need be externally visible.) All
-global function names should begin with "jpeg_", and should have an
-abbreviated name (unique in the first six characters) substituted by macro
-when NEED_SHORT_EXTERNAL_NAMES is set.
-
-3. Don't use global variables; anything that must be used in another module
-should be in the common data structures.
-
-4. Don't use static variables except for read-only constant tables. Variables
-that should be private to a module can be placed into private structures (see
-the system architecture document, structure.txt).
-
-5. Source file names should begin with "j" for files that are part of the
-library proper; source files that are not part of the library, such as cjpeg.c
-and djpeg.c, do not begin with "j". Keep source file names to eight
-characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep
-compression and decompression code in separate source files --- some
-applications may want only one half of the library.
-
-Note: these rules (particularly #4) are not followed religiously in the
-modules that are used in cjpeg/djpeg but are not part of the JPEG library
-proper. Those modules are not really intended to be used in other
-applications.

- * SOME FINE POINTS:

- * variables then you should be careful to increment them properly.
- * Actually, for output to a stdio stream you needn't worry, because
- * then jpeg_write_scanlines will write all the lines passed (or else exit
- * with a fatal error). Partial writes can only occur if you use a data
- * destination module that can demand suspension of the compressor.
- * (If you don't know what that's for, you don't need it.)
- *
- * If the compressor requires full-image buffers (for entropy-coding
- * optimization or a multi-scan JPEG file), it will create temporary
- * files for anything that doesn't fit within the maximum-memory setting.
- * (Note that temp files are NOT needed if you use the default parameters.)
- * On some systems you may need to set up a signal handler to ensure that
- * temporary files are deleted if the program is interrupted. See libjpeg.txt.
- *
- * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
- * files to be compatible with everyone else's. If you cannot readily read
- * your data in that order, you'll need an intermediate array to hold the
- * image. See rdtarga.c or rdbmp.c for examples of handling bottom-to-top
- * source data using the JPEG code's internal virtual-array mechanisms.

-/******************** JPEG DECOMPRESSION SAMPLE INTERFACE *******************/
-
-/* This half of the example shows how to read data from the JPEG decompressor.
- * It's a bit more refined than the above, in that we show:
- * (a) how to modify the JPEG library's standard error-reporting behavior;
- * (b) how to allocate workspace using the library's memory manager.
- *
- * Just to make this example a little different from the first one, we'll
- * assume that we do not intend to put the whole image into an in-memory
- * buffer, but to send it line-by-line someplace else. We need a one-
- * scanline-high JSAMPLE array as a work buffer, and we will let the JPEG
- * memory manager allocate it for us. This approach is actually quite useful
- * because we don't need to remember to deallocate the buffer separately: it
- * will go away automatically when the JPEG object is cleaned up.
- */
-
-
-/*
- * ERROR HANDLING:
- *
- * The JPEG library's standard error handler (jerror.c) is divided into
- * several "methods" which you can override individually. This lets you
- * adjust the behavior without duplicating a lot of code, which you might
- * have to update with each future release.
- *
- * Our example here shows how to override the "error_exit" method so that
- * control is returned to the library's caller when a fatal error occurs,
- * rather than calling exit() as the standard error_exit method does.
- *
- * We use C's setjmp/longjmp facility to return control. This means that the
- * routine which calls the JPEG library must first execute a setjmp() call to
- * establish the return point. We want the replacement error_exit to do a
- * longjmp(). But we need to make the setjmp buffer accessible to the
- * error_exit routine. To do this, we make a private extension of the
- * standard JPEG error handler object. (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)
- *
- * Here's the extended error handler struct:
- */
-
-struct my_error_mgr {
- struct jpeg_error_mgr pub; /* "public" fields */
-
- jmp_buf setjmp_buffer; /* for return to caller */

-IJG JPEG LIBRARY: FILE LIST
-
-Copyright (C) 1994-2009, Thomas G. Lane, Guido Vollbeding.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Here is a road map to the files in the IJG JPEG distribution. The
-distribution includes the JPEG library proper, plus two application
-programs ("cjpeg" and "djpeg") which use the library to convert JPEG
-files to and from some other popular image formats. A third application
-"jpegtran" uses the library to do lossless conversion between different
-variants of JPEG. There are also two stand-alone applications,
-"rdjpgcom" and "wrjpgcom".
-
-
-THE JPEG LIBRARY
-================
-
-Include files:
-
-jpeglib.h JPEG library's exported data and function declarations.
-jconfig.h Configuration declarations. Note: this file is not present
- in the distribution; it is generated during installation.
-jmorecfg.h Additional configuration declarations; need not be changed
- for a standard installation.
-jerror.h Declares JPEG library's error and trace message codes.
-jinclude.h Central include file used by all IJG .c files to reference
- system include files.
-jpegint.h JPEG library's internal data structures.
-jdct.h Private declarations for forward & reverse DCT subsystems.
-jmemsys.h Private declarations for memory management subsystem.
-jversion.h Version information.
-
-Applications using the library should include jpeglib.h (which in turn
-includes jconfig.h and jmorecfg.h). Optionally, jerror.h may be included
-if the application needs to reference individual JPEG error codes. The
-other include files are intended for internal use and would not normally
-be included by an application program. (cjpeg/djpeg/etc do use jinclude.h,
-since its function is to improve portability of the whole IJG distribution.
-Most other applications will directly include the system include files they
-want, and hence won't need jinclude.h.)
-
-
-C source code files:
-
-These files contain most of the functions intended to be called directly by
-an application program:
-
-jcapimin.c Application program interface: core routines for compression.
-jcapistd.c Application program interface: standard compression.
-jdapimin.c Application program interface: core routines for decompression.
-jdapistd.c Application program interface: standard decompression.
-jcomapi.c Application program interface routines common to compression
- and decompression.
-jcparam.c Compression parameter setting helper routines.
-jctrans.c API and library routines for transcoding compression.
-jdtrans.c API and library routines for transcoding decompression.
-
-Compression side of the library:
-
-jcinit.c Initialization: determines which other modules to use.
-jcmaster.c Master control: setup and inter-pass sequencing logic.
-jcmainct.c Main buffer controller (preprocessor => JPEG compressor).
-jcprepct.c Preprocessor buffer controller.
-jccoefct.c Buffer controller for DCT coefficient buffer.
-jccolor.c Color space conversion.
-jcsample.c Downsampling.
-jcdctmgr.c DCT manager (DCT implementation selection & control).
-jfdctint.c Forward DCT using slow-but-accurate integer method.
-jfdctfst.c Forward DCT using faster, less accurate integer method.
-jfdctflt.c Forward DCT using floating-point arithmetic.
-jchuff.c Huffman entropy coding.
-jcarith.c Arithmetic entropy coding.
-jcmarker.c JPEG marker writing.
-jdatadst.c Data destination managers for memory and stdio output.
-
-Decompression side of the library:
-
-jdmaster.c Master control: determines which other modules to use.
-jdinput.c Input controller: controls input processing modules.
-jdmainct.c Main buffer controller (JPEG decompressor => postprocessor).
-jdcoefct.c Buffer controller for DCT coefficient buffer.
-jdpostct.c Postprocessor buffer controller.
-jdmarker.c JPEG marker reading.
-jdhuff.c Huffman entropy decoding.
-jdarith.c Arithmetic entropy decoding.
-jddctmgr.c IDCT manager (IDCT implementation selection & control).
-jidctint.c Inverse DCT using slow-but-accurate integer method.
-jidctfst.c Inverse DCT using faster, less accurate integer method.
-jidctflt.c Inverse DCT using floating-point arithmetic.
-jdsample.c Upsampling.
-jdcolor.c Color space conversion.
-jdmerge.c Merged upsampling/color conversion (faster, lower quality).
-jquant1.c One-pass color quantization using a fixed-spacing colormap.
-jquant2.c Two-pass color quantization using a custom-generated colormap.
- Also handles one-pass quantization to an externally given map.
-jdatasrc.c Data source managers for memory and stdio input.
-
-Support files for both compression and decompression:
-
-jaricom.c Tables for common use in arithmetic entropy encoding and
- decoding routines.
-jerror.c Standard error handling routines (application replaceable).
-jmemmgr.c System-independent (more or less) memory management code.
-jutils.c Miscellaneous utility routines.
-
-jmemmgr.c relies on a system-dependent memory management module. The IJG
-distribution includes the following implementations of the system-dependent
-module:
-
-jmemnobs.c "No backing store": assumes adequate virtual memory exists.
-jmemansi.c Makes temporary files with ANSI-standard routine tmpfile().
-jmemname.c Makes temporary files with program-generated file names.
-jmemdos.c Custom implementation for MS-DOS (16-bit environment only):
- can use extended and expanded memory as well as temp files.
-jmemmac.c Custom implementation for Apple Macintosh.
-
-Exactly one of the system-dependent modules should be configured into an
-installed JPEG library (see install.txt for hints about which one to use).
-On unusual systems you may find it worthwhile to make a special
-system-dependent memory manager.
-
-
-Non-C source code files:
-
-jmemdosa.asm 80x86 assembly code support for jmemdos.c; used only in
- MS-DOS-specific configurations of the JPEG library.
-
-
-CJPEG/DJPEG/JPEGTRAN
-====================
-
-Include files:
-
-cdjpeg.h Declarations shared by cjpeg/djpeg/jpegtran modules.
-cderror.h Additional error and trace message codes for cjpeg et al.
-transupp.h Declarations for jpegtran support routines in transupp.c.
-
-C source code files:
-
-cjpeg.c Main program for cjpeg.
-djpeg.c Main program for djpeg.
-jpegtran.c Main program for jpegtran.
-cdjpeg.c Utility routines used by all three programs.
-rdcolmap.c Code to read a colormap file for djpeg's "-map" switch.
-rdswitch.c Code to process some of cjpeg's more complex switches.
- Also used by jpegtran.
-transupp.c Support code for jpegtran: lossless image manipulations.
-
-Image file reader modules for cjpeg:
-
-rdbmp.c BMP file input.
-rdgif.c GIF file input (now just a stub).
-rdppm.c PPM/PGM file input.
-rdrle.c Utah RLE file input.
-rdtarga.c Targa file input.
-
-Image file writer modules for djpeg:
-
-wrbmp.c BMP file output.
-wrgif.c GIF file output (a mere shadow of its former self).
-wrppm.c PPM/PGM file output.
-wrrle.c Utah RLE file output.
-wrtarga.c Targa file output.
-
-
-RDJPGCOM/WRJPGCOM
-=================
-
-C source code files:
-
-rdjpgcom.c Stand-alone rdjpgcom application.
-wrjpgcom.c Stand-alone wrjpgcom application.
-
-These programs do not depend on the IJG library. They do use
-jconfig.h and jinclude.h, only to improve portability.
-
-

-
-README Master documentation file.
-*.txt Other documentation files.

-/**************** RGB -> YCbCr conversion: most common case **************/
-
-/*
- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- * Y = 0.29900 * R + 0.58700 * G + 0.11400 * B
- * Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B + CENTERJSAMPLE
- * Cr = 0.50000 * R - 0.41869 * G - 0.08131 * B + CENTERJSAMPLE
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,
- * rather than CENTERJSAMPLE, for Cb and Cr. This gave equal positive and
- * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)
- * were not represented exactly. Now we sacrifice exact representation of
- * maximum red and maximum blue in order to get exact grayscales.
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times R,G,B for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 12-bit samples it is still acceptable. It's not very reasonable for
- * 16-bit samples, but if you want lossless storage you shouldn't be changing
- * colorspace anyway.
- * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included
- * in the tables to save adding them separately in the inner loop.

- *
- * The JPEG standard requires Huffman codes to be no more than 16 bits long.

- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- * R = Y + 1.40200 * Cr
- * G = Y - 0.34414 * Cb - 0.71414 * Cr
- * B = Y + 1.77200 * Cb
- * where Cb and Cr represent the incoming values less CENTERJSAMPLE.
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- * Notice that Y, being an integral input, does not contribute any fraction
- * so it need not participate in the rounding.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times Cb and Cr for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 12-bit samples it is still acceptable. It's not very reasonable for
- * 16-bit samples, but if you want lossless storage you shouldn't be changing
- * colorspace anyway.
- * The Cr=>R and Cb=>B values can be rounded to integers in advance; the
- * values for the G calculation are left scaled up, since we must add them
- * together before rounding.
