FT_Forget_Frame blocks to avoid leaving the stream in an incorrect state when encountering an invalid PCF font). * src/pcf/pcfdriver.c (PCF_Done_Face): Renamed to ... (PCF_Face_Done): This. (PCF_Init_Face): Renamed to ... (PCF_Face_Init): This. (PCF_Get_Char_Index): Renamed to ... (PCF_Char_Get_Index): This. (PCF_Get_Next_Char): Renamed to ... (PCF_Char_Get_Next): This. (pcf_driver_class): Updated. * src/pcf/pcf.h (PCF_Done_Face): Removed. 2002-02-06 Detlef Würkner * src/pcf/pcfdriver.c (FT_Done_Face): Fixed small memory leak. * src/pcf/pcfread.c (pcf_load_font): Now handles the `AVERAGE_WIDTH' property to return correct character pixel (width/height) pairs for embedded bitmaps. 2002-02-04 Keith Packard Adding the function `FT_Get_Next_Char', doing the obvious thing w.r.t. the selected charmap. * include/freetype/freetype.h: Add prototype. * include/freetype/internal/ftdriver.h: Add `FTDriver_getNextChar' typedef. (FT_Driver_Class): Use it. * include/freetype/internal/psnames.h: Add `PS_Next_Unicode_Func' typedef.

(t1_driver_class): Add it. * src/winfonts/winfnt.c (FNT_Get_Next_Char): New function. (winfnt_driver_class): Add it. * src/pcf/pcfread.c (pcf_load_font): For now, report Unicode for Unicode and Latin 1 encodings. 2002-02-02 Keith Packard * builds/unix/freetype-config.in: Add missing `fi'. * Version 2.0.7 released. ========================= 2002-02-01 David Turner * include/freetype/freetype.h: Increasing FREETYPE_PATCH to 7 for the new release. 2002-01-31 David Turner * README, README.UNX, docs/CHANGES: Updating documentation for the 2.0.7 release. 2002-01-30 David Turner * INSTALL: Moved to ... * docs/INSTALL: Here to avoid conflicts with the `install' script on Windows, where the filesystem doesn't preserve case. 2002-01-29 David Turner * configure: Fixed the script. It previously didn't accept more than one argument correctly. For example, when typing: ./configure --disable-shared --disable-nls the `--disable-nls' was incorrectly sent to the `make' program. 2002-01-29 Werner Lemberg * README.UNX: Fix typo. * builds/unix/install.mk (uninstall): Fix library name for libtool. 2002-01-28 Francesco Zappa Nardelli * src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of the face object (face->toc.tables, face->root.family_name, face->root.available_size, face->charset_encoding, face->charset_registry are now freed). Thanks to Niels Moseley. 2002-01-28 Roberto Alameda * src/type1/t1load.c (parse_encoding): Set `loader->num_chars'. 2002-01-28 Werner Lemberg * src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy of `base' string for decrypting to not modify the original data. Based on a patch by Jakub Bogusz . 2002-01-27 Giuliano Pochini * src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused bad rendering of thin lines (less than one pixel thick). 2002-01-25 Werner Lemberg * src/cff/cffdrivr.c (cff_get_name_index): Make last patch work actually. 2002-01-25 Martin Zinser * src/cache/ftccache.c (ftc_node_done, ftc_node_destroy): Fix compilation warnings. * src/base/descrip.mms (OBJS): Add `ftmm.obj'. * src/cache/descrip.mms (ftcache.obj): Dependencies added. 2002-01-25 WANG Yi * src/cff/cffdrivr.c (cff_get_name_index): Fix deallocation bug. 2002-01-21 Antoine Leca * docs/PATENTS: Typo fixed (thanks to Detlef `Hawkeye' Würkner) in the URL for the online resource. 2002-01-18 Ian Brown * builds/win32/ftdebug.c: New file. * builds/win32/visualc/freetype.dsp: Updated. 2002-01-18 Detlef Würkner * builds/amiga/src/base/ftsystem.c: Updated for AmigaOS 3.9. * builds/amiga/README: Updated. 2002-01-18 Ian Brown * builds/win32/visualc/freetype.dsp: Updated. 2002-01-13 Werner Lemberg * builds/unix/freetype2.a4: The script was still buggy. * builds/unix/freetype-config.in: Make it really work for any install prefix. 2002-01-10 Werner Lemberg * builds/unix/freetype2.a4: Fix some serious bugs. 2002-01-09 David Turner * builds/unix/configure.ac: Build top-level Jamfile. 2002-01-09 Maxim Shemanarev * src/smooth/ftgrays.c (gray_render_line): Small optimization to the smooth anti-aliased renderer that deals with vertical segments. This results in a 5-7% speedup in rendering speed. 2002-01-08 David Turner Added some wrapper scripts to make the installation more Unix-friendly. * configure, install: New files. * INSTALL, README.UNX: Updated installation documentation to use the new 'configure' and 'install' scripts. 2002-01-07 David Turner * Version 2.0.6 released. ========================= * docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release. * src/tools/docmaker.py: Fixed HTML quoting in sources. (html_format): Replaced with ... (html_quote): New function. (html_quote0): New function. (DocCode::dump_html): Small improvement. (DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote. * include/freetype/config/ftoption.h: Setting default options for a release build (debugging off, bytecode interpreter off). * src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c, src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c, src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler warnings (in pedantic compilation modes). 2002-01-05 David Turner * src/autohint/ahhint.c (ah_align_linked_edge): Modified computation of auto-hinted stem widths; this avoids color fringes in `ClearType-like' rendering. * src/truetype/ttgload.c (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph): Modified the TrueType loader to make it more paranoid; this avoids nasty buffer overflows in the case of invalid glyph data (as encountered in the output of some buggy font converters). 2002-01-04 David Turner * README.UNX: Added special README file for Unix users. * builds/unix/ftsystem.c (FT_New_Stream): Fixed typo. * src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid of compiler warnings. * src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning. 2002-01-03 Werner Lemberg * src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler warning. 2002-01-03 Keith Packard * builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that all FreeType input streams are closed in child processes of a `fork' on Unix systems. This is important to avoid (potential) access control issues. 2002-01-03 David Turner * src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the library when dealing with certain weird fonts like `Stalingrad', in `sadn.pfb' (this font has no full font name entry). * src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check): New function to check the consistency of outline data. * src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to ensure that loaded glyphs are valid. This allows certain fonts like `tt1095m_.ttf' to be loaded even though it appears they contain really funky glyphs. There still is a bug there, though. * src/truetype/ttgload.c (load_truetype_glyph): Fix error condition. 2001-12-30 David Turner * src/autohint/ahhint.c (ah_hinter_load): Fix advance width computation of auto-hinted glyphs. This noticeably improves the spacing of letters in KDE and Gnome. 2001-12-25 Antoine Leca * builds/dos/detect.mk: Correcting the order for Borland compilers: 16-bit bcc was never selected, always overridden by 32-bit bcc32. 2001-12-22 Francesco Zappa Nardelli * src/pfc/pcfread.c (pcf_load_font): Handle property `POINT_SIZE' and fix incorrect computation of `available_sizes'. 2001-12-22 David Turner * src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an incorrect glyph advance in the case of mono-width fonts (like Courier, Andale Mono, and others). 2001-12-22 Detlef Würkner * builds/amiga/*: Adaptations to latest changes. Support added for MorphOS. 2001-12-22 Werner Lemberg * src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'. (ps_mask_table_merge, ps_hints_open, ps_hints_stem, ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix FT_ERROR messages. * src/pshinter/pshalgo1.c (FT_COMPONENT): Define as `trace_pshalgo1'. * src/pshinter/pshalgo2.c (FT_COMPONENT): Define as `trace_pshalgo2'. * include/freetype/internal/ftdebug.h (FT_Trace): Updated. * docs/modules.txt: New file. 2001-12-21 David Turner * src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter): Ignore invalid `hintmask' and `cntrmask' operators (instead of returning an error). Glyph 2028 of the CFF font `MSung-Light-Acro' couldn't be rendered otherwise (it seems its charstring is buggy, though this requires more analysis). (FT_COMPONENT): Define. * src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a bug where the X and Y axis where inverted in the postscript hinter. This caused problem when displaying on non-square surfaces. * src/pshinter/pshalgo2.c: s/vertical/dimension/. * src/pshinter/pshglob.c (psh_globals_new): Replaced a floating point constant with a fixed-float equivalent. For some reasons not all compilers are capable of directly computing a floating pointer constant casted to FT_Fixed, and will link a math library instead. 2001-12-20 Werner Lemberg * src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix tracing strings. * src/cache/ftccmap.c (ftc_cmap_family_init): Ditto. * src/cache/ftcmanag.c (ftc_family_table_alloc, ftc_family_table_free, FTC_Manager_Check): Ditto. * src/cache/ftcsbits.c (ftc_sbit_node_load): Ditto. * src/base/ftobjs.c (FT_Done_Library): Remove compiler warning. 2001-12-20 David Turner Added PostScript hinter support to the CFF and CID drivers. * include/freetype/internal/cfftypes.h (CFF_Font): New member `pshinter'. * src/cff/cffload.c (CFF_Get_Standard_Encoding): New function. * src/cff/cffload.h: Updated. * src/cff/cffgload.c (CFF_Init_Builder): Renamed to ... (CFF_Builder_Init): This. Added new argument `hinting'. (CFF_Done_Builder): Renamed to ... (CFF_Builder_Done): This. (CFF_Init_Decoder): Added new argument `hinting'. (CFF_Parse_CharStrings): Implement vstem support. (CFF_Load_Glyph): Updated. Add hinting support. (cff_lookup_glyph_by_stdcharcode): Use CFF_Get_Standard_Encoding(). (cff_argument_counts): Updated. * src/cff/cffgload.h: Updated. * src/cff/cffobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_Size_Get_Globals_Funcs, CFF_Size_Done, CFF_Size_Init, CFF_Size_Reset, CFF_GlyphSlot_Done, CFF_GLyphSlot_Init): New functions. (CFF_Init_Face): Renamed to ... (CFF_Face_Init): This. Add hinter support. (CFF_Done_Face): Renamed to ... (CFF_Face_Done): This. (CFF_Init_Driver): Renamed to ... (CFF_Driver_Init): This. (CFF_Done_Driver): Renamed to ... (CFF_Driver_Done): This. * src/cff/cffobjs.h: Updated. * src/cff/cffdrivr.c (cff_driver_class): Updated. * include/freetype/internal/t1types.h (CID_FaceRec): New member `pshinter'. * src/cid/cidgload.c (CID_Load_Glyph): Add hinter support. * src/cid/cidobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CID_GlyphSlot_Done, CID_GlyphSlot_Init, CID_Size_Get_Globals_Funcs, CID_Size_Done, CID_Size_Init, CID_Size_Reset): New functions. (CID_Done_Face): Renamed to ... (CID_Face_Done): This. (CID_Init_Face): Renamed to ... (CID_Face_Init): This. Add hinting support. (CID_Init_Driver): Renamed to ... (CID_Driver_Init): This. (CID_Done_Driver): Renamed to ... (CID_Driver_Done): This. * src/cid/cidobjs.h: Updated. * src/cidriver.c: Updated. * src/pshinter/pshrec.c (t2_hint_stems): Fixed. * src/base/ftobjs.c (FT_Done_Library): Fixed a stupid bug that crashed the library on exit. * src/type1/t1gload.c (T1_Load_Glyph): Enable font matrix transformation of hinted glyphs. * src/cid/cidload.c (cid_read_subrs): Fix error condition. * src/cid/cidobjs.c (CID_Face_Done): Fixed a memory leak; the subrs routines were never released when CID faces were destroyed. * src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated to move the definition of encoding tables back within `cffload.c' instead of making them part of a shared header (causing problems in `multi' builds). This reverts change 2001-08-08. * docs/CHANGES: Updated for 2.0.6 release. * docs/TODO: Added `stem3 and counter hints support' to the TODO list for the Postscript hinter. * docs/BUGS: Closed the AUTOHINT-NO-SBITS bug. 2001-12-19 David Turner * include/freetype/cache/ftcache.h: Added comments to indicate that some of the exported functions should only be used by applications that need to implement custom cache types. * src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug that prevented composites from loading correctly, due to missing parentheses around macro parameters. * src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name' tables optional to load PCL fonts properly. * src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c (FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY): `Fixed' the bug that prevented embedded bitmaps to be loaded when the auto-hinter is used. This actually is a hack but will be enough until the internal re-design scheduled for FreeType 2.1. * src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline shifting bug in the monochrome renderer. * README: Updated version numbers to 2.0.6. 2001-12-17 Werner Lemberg * src/truetype/ttgload.c (load_truetype_glyph): Fix test for invalid glyph header. 2001-12-15 Werner Lemberg * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Remove compiler warning. * include/freetype/ftcache.h (FTC_Node_Unref): Removed. It is already in ftcmanag.h. * src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused variable `gfam'. * src/cache/ftcmanag.c (ftc_family_table_alloc, * ftc_family_table_free): Use FT_EXPORT_DEF. * include/freetype/cache/ftcmanag.h: Updated. * src/cache/ftccache.c (ftc_node_destroy): Use FT_EXPORT_DEF. * src/cache/ftccmap.c (ftc_cmap_node_init): Remove unused variable `cfam'. Remove compiler warning. (FTC_CMapCache_Lookup): Remove compiler warnings. (ftc_cmap_family_init): Ditto. (FTC_CMapCache_Lookup): Ditto. * builds/unix/configure.ac: Increase `version_info' to 8:0:2. * builds/unix/configure: Regenerated. 2001-12-14 Werner Lemberg * builds/mac/README: Updated. 2001-12-14 Scott Long * src/truetype/ttgload.c (load_truetype_glyph): Fixing crash when dealing with invalid fonts (i.e. glyph size < 10 bytes). 2001-12-14 Sam Latinga * builds/mac/freetype.make: A new Makefile to build with MPW on MacOS classic. 2001-12-14 David Turner * src/truetype/ttgload.c (TT_Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph), src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to all font drivers (the advance width was never hinted when it should). * include/freetype/freetype.h (FREETYPE_PATCH): New macro. * src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't use `extern' keyword. 2001-12-12 David Turner * src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem psh_globals_new): Adding correct BlueScale/BlueShift support, plus family blues processing. * src/pshinter/pshglob.h (PSH_BluesRec): Updated.

We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I didn't modify builds/unix/install.mk yet. * INSTALL: Updated the instructions to build shared libraries with Jam. They were simply wrong. * src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused slightly improper results for `FT_Cos' and `FT_Sin' (example: FT_Sin(0) == -1!). 2001-12-11 Detlef Würkner * include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE): Fixed incorrect argument types. 2001-12-10 Francesco Zappa Nardelli * src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts by setting the `face->metrics.max_advance' correctly. 2001-12-07 David Turner * include/freetype/cache/ftccmap.h, src/cache/ftccmap.c: Added new charmap cache. * src/cache/ftcache.c: Updated. * src/autohint/ahhint.c (ah_hinter_hint_edges): s/UNUSED/FT_UNUSED/. 2001-12-06 Leonard Rosenthol Added support for reading .dfont files on Mac OS X. Also added a new routine which looks up a given font by name in the Mac OS and returns the disk file where it resides. * src/base/ftmac.c: Include and . (is_dfont): New auxiliary function. (FT_New_Face_From_dfont): New function. (FT_GetFile_From_Mac_Name): New exported function. (FT_New_Face): Updated. * include/freetype/ftmac.h: Updated. 2001-12-06 David Turner * src/cache/Jamfile, src/cache/rules.mk: Updated. 2001-12-06 Werner Lemberg * INSTALL: Small update. 2001-12-05 David Turner * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for debugging purposes. Comment out use of `origin'. * src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug where outline shifting wasn't correctly undone after bitmap rasterization. This created problems with certain glyphs (like '"' of certain fonts) and the cache system. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo. * src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo. (ps2_hints_apply): Small fix. 2001-12-05 David Turner * src/pshinter/pshalgo2.c (psh2_hint_table_init), src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler warnings. * include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*: Yet another massive rewrite of the caching sub-system in order to both increase performance and allow simpler cache sub-classing. As an example, the code for the image and sbit caches is now much simpler. I still need to update the documentation in www/freetype2/docs/cache.html to reflect the new design though. * include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New macro. (FT_CACHE_INTERNAL_CACHE_H): Updated. 2001-12-05 David Krause * docs/license.txt: s/X Windows/X Window System/. 2001-12-04 Werner Lemberg * src/raster/ftraster.c: Fix definition condition of MEM_Set(). * src/smooth/ftgrays.c (M_Y): Change value to 192. * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter. Remove unused variable. * src/cache/ftcimage.c (ftc_image_node_init, ftc_image_node_compare): Remove unused variables. * src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused variable. * src/raster/ftraster.c (MEM_Set): Move definition down to avoid compiler warning. * src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to avoid compiler warnings. * src/pcf/pcfread.c (tableNames): Use `const'. (pcf_read_TOC): Change counter name to avoid compiler warning. Use `const'. * src/pshinter/pshrec.c (ps_hints_close): Remove redundant declaration. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables to avoid shadowing. * src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto. * src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()' and `T1_Size_Done()'. 2001-11-20 Antoine Leca * include/freetype/ttnameid.h: Added some new Microsoft language codes and LCIDs as found in MSDN (Passport SDK). Also added comments about the meaning of bit 57 of the `OS/2' table (TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is a character beyond 0xFFFF in this font'. Thanks to Detlef Würkner for noticing this. 2001-11-20 David Turner * src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting routine that created nasty alignment artefacts. * src/pshinter/pshrec.c, tests/gview.c: Debugging updates. * src/smooth/ftgrays.c: De-activated experimental gamma support. Apparently, `optimal' gamma tables depend on the monitor type, resolution and general karma, so it's better to compute them outside of the rasterizer itself. (gray_convert_glyph): Use `volatile' keyword. 2001-10-29 David Turner Adding experimental `gamma' support. This produces smoother glyphs at small sizes for very little cost. * src/smooth/ftgrays.c (grays_init_gamma): New function. (gray_raster_new): Use it. Various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters). * src/autohint/ahglyph.c (ah_outline_load, ah_outline_link_segments): Implement it. Fix typos. (ah_outline_save, ah_outline_compute_segments): Fix typos. * src/autohint/ahhint.c (ah_align_serif_edge): New argument `vertical'. Implement improvement. (ah_hint_edges_3, ah_hinter_hint_edges): Implement it. Fix typos. (ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix typos. (ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined. * src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro. * src/autohint/ahtypes.h: Ditto. (AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges' (making them global as `ah_debug_disable_horz' and `ah_debug_disable_vert'). Fix typos. * tests/gview.c: Updated the debugging glyph viewer to show the hints generated by the `autohint' module. 2001-10-27 David Turner * src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that considerably lowered the performance of the abstract chunk cache. 2001-10-26 David Turner * include/freetype/ftcache.h, include/freetype/cache/*.h, src/cache/*.c: Major re-design of the cache sub-system to provide better performance as well as an `Acquire'/`Release' API. Seems to work well here, but probably needs a bit more testing. 2001-10-26 Leonard Rosenthol * builds/mac/README: Updated to reflect my taking over the project and that is now being actively maintained. * src/base/ftmac.c (parse_fond): Applied patches from Paul Miller to support loading a face other than the first from a FOND resource. (FT_New_Face_From_FOND): Updated. 2001-10-25 Leonard Rosenthol * builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac OS for latest version (7) of CWPro and for recent changes to the FT source tree. 2001-10-25 David Turner * include/freetype/config/ftoption.h: Updated comments to explain precisely how to use project-specific macro definitions without modifying this file manually. (FT_CONFIG_FORCE_INT64): Define. (FT_DEBUG_MEMORY): New macro. 2001-10-24 Tom Kacvinsky * builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'. 2001-10-23 David Turner * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: Improvements to the memory debugger to report more information in case of errors. Also, some allocations that occurred through REALLOC couldn't be previously caught correctly. * src/autohint/ahglyph.c (ah_outline_compute_segments, ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new), src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced liberal uses of memset() by the MEM_Set() macro. 2001-10-23 David Turner * src/raster/ftraster.c (Update): Removed to be inlined in ...

You must define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it. It will record every memory block allocated and report simple errors like memory leaks and double deletes. * src/base/Jamfile: Include ftdbgmem. * src/base/rules.mk: Ditto. * src/base/ftbase.c: Include ftdbgmem.c. * include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY macro definition. * src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the base component to use the debugging memory manager when the macro FT_DEBUG_MEMORY is defined. 2001-10-21 Tom Kacvinsky * src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if we are working with a CID keyed CFF font. Otherwise, a variable that was never allocated memory might freed. This is a correction to the previous patch for freeing subfonts. 2001-10-21 Tom Kacvinsky * src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to avoid a memory leak. 2001-10-21 David Turner * src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c, src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes (in multi-object compilation mode, mainly). 2001-10-20 Tom Kacvinsky * src/type1/t1load.c (parse_encoding): Add a test to make sure that custom encodings (i.e., neither StandardEncoding nor ExpertEncoding) are not loaded twice when the Type 1 font is synthetic. * src/type1/t1load.c (parse_font_name, parse_subrs): Added a test for when loading synthetic fonts to make sure that the font name and subroutines are not loaded twice. This is to remove a memory leak that occurred because the original memory blocks for these objects were not deallocated when the objects were parsed the second time. 2001-10-19 David Turner * src/smooth/ftgrays.c, src/pshinter/pshglob.h, src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of compiler warnings. * src/pshinter/module.mk, src/pshinter/rules.mk: Adding control files to build the PostScript hinter with the `old' build system. 2001-10-19 Jacob Jansen * descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build files. 2001-10-18 David Turner * src/psnames/pstables.h, src/tools/glnames.py: Rewrote the `glnames.py' script used to generate the `pstables.h' header file. The old one contained a serious bug that made FreeType return incorrect glyph names for certain glyphs. * src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of pixel size from character size to use rounding. This is an experiment to see whether this gives values similar to Windows for scaled ascent/descent/etc. * src/base/ftcalc.c (FT_Div64by32): Changed the implementation slightly since the original code was mis-compiled on Mac machines using the MPW C compiler. * src/base/ftobjs.c (FT_Realloc): When a memory block was grown through FT_Realloc(), the new bytes were not set to 0, which created some strange bugs in the PostScript hinter. (destroy_face): Don't deallocate unconditionally. * src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph): Adding support to new PostScript hinter. * include/freetype/internal/psglobal.h, include/freetype/internal/pshints.h, include/freetype/config/ftmodule.h, src/pshinter/Jamfile, src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshglob.h, src/pshinter/pshglob.c, src/pshinter/pshinter.c, src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c, src/pshinter/pshrec.h: Adding new PostScript hinter module. * include/freetype/internal/ftobjs.h, include/freetype/internal/internal.h, include/freetype/internal/psaux.h, include/freetype/internal/t1types.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c, src/type1/t1objs.h: Updates to use the new PostScript hinter. * tests/Jamfile, tests/gview.c: Adding a new glyph hinting viewer/debugger to the source tree. Note that you will _not_ be able to compile it since it depends on an unavailable graphics library named `Nirvana' to render vector images. 2001-10-17 David Turner * Version 2.0.5 released. ========================= * include/freetype/freetype.h, include/internal/ftobjs.h, src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named 'FT_Get_Postscript_Name' to retrieve the PostScript name of a given font.

ANSI C doesn't (explicitly) allow macro expansion in arguments using `##'. (FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory names directly. Make them configurable. Use `##' to strip leading and trailing spaces from arguments. * builds/unix/ft2unix.h: Adapted. * src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream, ft_close_stream): Use FT_CALLBACK_DEF. * builds/unix/ftsystem.c: Use new header scheme. (FT_Done_Memory): Use free() from FT_Memory structure. * src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes. 2000-12-11 Werner Lemberg * include/freetype/config/ft2build.h (FT2_CONFIG_ROOT, FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE, FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant. 2000-12-09 Werner Lemberg * builds/unix/detect.mk: Remove unused USE_CFLAGS variable. 2000-12-08 Werner Lemberg * */*.h: Changed body inclusion macro names to start and end with `__' (those which haven't converted yet). Fixed minor conversion issues. * src/winfonts/winfnt.c: Updated to new header inclusion scheme. * src/truetype/ttinterp.c: Remove unused CALC_Length() macro. 2000-12-07 David Turner * */*.[ch]: Changed source files to adhere to the new header inclusion scheme. Not completely tested but works for now here. * src/cff/t2driver.c: Renamed and updated to... * src/cff/cffdrivr.c: New file. * src/cff/t2driver.h: Renamed and updated to... * src/cff/cffdrivr.h: New file. * src/cff/t2load.c: Renamed and updated to... * src/cff/cffload.c: New file. * src/cff/t2load.h: Renamed and updated to... * src/cff/cffload.h: New file. * src/cff/t2objs.c: Renamed and updated to... * src/cff/cffobjs.c: New file. * src/cff/t2objs.h: Renamed and updated to... * src/cff/cffobjs.h: New file. * src/cff/t2parse.c: Renamed and updated to... * src/cff/cffparse.c: New file. * src/cff/t2parse.h: Renamed and updated to... * src/cff/cffparse.h: New file. * src/cff/t2tokens.h: Renamed and updated to... * src/cff/cfftoken.h: New file. * src/cff/cff.c, src/cff/rules.mk: Updated. 2000-12-06 David Turner * src/cache/ftlru.c (FT_Lru_Done): Fixed memory leak. 2000-12-06 Werner Lemberg * builds/module.mk: Replaced `xxx #' with `xxx$(space). * builds/os2/detekt.mk, builds/win32/detekt.mk: Moved comment to avoid trailing spaces in variable. * builds/freetype.mk: Use $(D) instead of $D to make statement more readable. * docs/docmaker.py: Formatting. 2000-12-05 David Turner * src/psaux/psauxmod.c: Fixed a broken inclusion of component header files (an FT_FLAT_COMPILE test was missing). * src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused an occasional crash when the function was called (due to a dangling pointer). * src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug: The ANSI `free()' function was called instead of `memory->free()'. * docs/docmaker.py: Added section filtering, multi-page generation (index page generation is still missing though). 2000-12-04 David Turner * builds/unix/install.mk, builds/unix/ft2unix.h: The file `ft2unix.h' is now installed as for Unix systems. Note that we still use the `freetype2/freetype' installation path for now. * */*.[ch]: Now using as the default build and setup configuration file in all public headers. Internal source files still need some changes though. * builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new directory to hold all development options for both the Unix and Win32 developer builds. * builds/win32/detect.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Changed the developer build targets to `devel-gcc' and `devel-bcc' in order to be able to develop with the Borland C++ compiler. 2000-12-01 David Turner * Version 2.0.1 released. ========================= * builds/unix/configure.in, builds/unix/configure, builds/cygwin/configure.in, builds/cygwin/configure: Setting `version_info' to 6:1:0 for the 2.0.1 release. * CHANGES: Added a summary of changes between 2.0.1 and 2.0. * builds/unix/ftconfig.in, builds/cygwin/ftconfig.in: Changes to allow compilation under Unix with the Unix-specific config files. 2000-12-01 Werner Lemberg * INSTALL: Revised. * builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk, builds/compiler/bcc.mk, builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk: Revised. * include/freetype/config/ftbuild.h, include/freetype/internal/internal.h: Revised. * include/freetype/ftimage.h: Updated to new header inclusion scheme. 2000-11-30 Werner Lemberg * builds/toplevel.mk (.PHONY): Adding `distclean'. * builds/unix/detect.mk (.PHONY): Adding `devel', `unix', `lcc', `setup'. 2000-11-30 David Turner * INSTALL: Slightly updated the quick starter documentation to include IDE compilation, prevent against BSD Make, and specify `make setup' instead of a single `make' for build configuration. * include/config/ftbuild.h, include/internal/internal.h: Added new configuration files used to determine the location of all public, configuration, and internal header files for FreeType 2. Modified all headers under `include/freetype' to reflect this change. Note that we still need to change the library source files themselves though. * builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk, builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk, builds/win32/detect.mk: Added new files to support compilation with the free Borland C++ command-line compiler. Modified the detection rules to recognize the new `bcc32' target in `make setup bcc32'. * src/sfnt/ttcmap.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c, src/truetype/ttobjs.c, src/truetype/ttgload.c, src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++ didn't really like. Basically, this compiler complains when FT_UInt is compared to FT_UShort (apparently, it promotes `UShort' to `Int' in these cases). 2000-11-30 Tom Kacvinsky * t2objs.c (T2_Init_Face): Added calculation of `face->height' for pure CFF fonts. * t1objs.c (T1_Init_Face): Fixed computation of `face->height'. 2000-11-29 David Turner * src/base/ftbbox.c (BBox_Conic_Check): Fixed a really stupid bug in the formula used to compute the conic Bézier extrema of non-monotonous arcs. 2000-11-29 Werner Lemberg * src/base/ftcalc.c (FT_SqrtFixed), src/base/ftobjs.c (FT_Set_Renderer): Use FT_EXPORT_DEF. * src/cache/ftcimage.c (FTC_Image_Cache_Lookup), src/cache/ftcmanag.c (FTC_Manager_Done, FTC_Manager_Reset, FTC_Manager_Lookup_Face, FTC_Manager_Lookup_Size, FTC_Manager_Register_Cache), src/cache/ftcsbits.c (FTC_SBit_Cache_Lookup): Ditto. * src/include/freetype/cache/ftcglyph.h (FTC_GlyphNode_Init), src/include/freetype/ftmac.h (FT_New_Face_From_FOND): Use FT_EXPORT. 2000-11-29 Werner Lemberg * src/sfnt/sfdriver.c: Include ttsbit.h and ttpost.h only conditionally. * src/truetype/ttdriver.c (Set_Char_Sizes, Set_Pixel_Sizes): Set `size->strike_index' only conditionally. * src/type1/t1driver.c, src/type1/t1objs.c: Include t1afm.h only conditionally. * src/winfonts/winfnt.h: Move all type definitions to... * src/include/freetype/internal/fnttypes.h: New file. * src/winfonts/winfnt.c: Use it. 2000-11-29 ??? ??? * include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT with a direct solution (which also satisfies picky compilers). 2000-11-28 YAMANO-UCHI Hidetoshi * src/truetype/ttobjs.c (TT_Init_Size): Fix #ifdef's to work with disabled interpreter also. * src/base/ftnames.c (FT_Get_Sfnt_Name_Count): Fix incorrect parentheses. 2000-11-26 Tom Kacvinsky * src/cff/t2gload.c (T2_Parse_CharStrings): Added logic to glyph width setting code to take into account even/odd argument counts and glyph width operand before endchar/hmoveto/vmoveto. 2000-11-26 Werner Lemberg * builds/ansi/ansi.mk: Fix inclusion order of files. 2000-11-26 Keith Packard * src/type1/t1objs.c (T1_Init_Face): Compute style flags. 2000-11-26 Werner Lemberg * builds/compiler/ansi-cc.mk (CLEAN_LIBRARY): Fix rule and conditional. 2000-11-23 Werner Lemberg * src/type1/t1load.c (parse_subrs, parse_charstrings): Use decrypt function from PSAux module. * src/type1/t1parse.c (T1_Done_Parse): Renamed to... (T1_Finalize_Parser): New function (to avoid name clash with a function in the PSAux module). (T1_Decrypt): Removed since it is duplicated in the PSAux module. (T1_Get_Private_Dict): Added `psaux' as new parameter; use decrypt function from PSAux module. * src/type1/t1parse.h: Adapted. 2000-11-22 Tom Kacvinsky * src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set `root->num_faces' to `cff->num_faces' and set `units_per_EM' to 1000. * src/cff/t2parse.c (parse_t2_real): Fixed real number parsing loop. * src/cff/t2load.c (T2_Get_String): Called T2_Get_Name with a sid that was off by one. 2000-11-16 David Turner * src/autohint/ahtypes.h (AH_Hinter): Added new fields to control auto-hinting of synthetic Type 1 fonts. * src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph): Added auto-hinting support of synthetic Type 1 fonts. 2000-11-12 Tom Kacvinsky * src/sfnt/ttload.c (TT_LookUp_Table, TT_Load_Generic_Table): Change tracing output. * src/sfnt/sfobjs.c (SFNT_Load_Face): Set boolean variable `has-outline' to true only if the font has a `glyf' or `CFF ' table. 2000-11-11 Werner Lemberg * builds/win32/visualc/freetype.dsp: Fix raster1->raster and type1z->type1. 2000-11-11 Tom Kacvinsky * builds/unix/freetype-config.in, builds/cygwin/freetype-config.in: Added a --libtool option. When freetype-config --libtool is invoked, the absolute path to the libtool convenience library is returned. 2000-11-11 Werner Lemberg * builds/cygwin/cygwin-def.in: Same fix as previous. 2000-11-10 Tom Kacvinsky * builds/unix/unix-def.in: Add INSTALL_PROGRAM := @INSTALL_PROGRAM@ INSTALL_SCRIPT := @INSTALL_SCRIPT@ so that installation of freetype-config does not fail. 2000-11-10 Werner Lemberg * builds/cygwin/freetype-config.in, builds/unix/freetype-config.in: Move test down for empty --exec-prefix. Fix --version. * builds/cygwin/install.mk, builds/unix/install.mk: Use $(INSTALL_SCRIPT) for installation of freetype-config. * builds/cygwin/install.mk: Fix clean target names. 2000-11-09 David Turner * Version 2.0 released. ======================= ---------------------------------------------------------------------------- Copyright 2000, 2001, 2002, 2007 by David Turner, Robert Wilhelm, and Werner Lemberg.
