David Turner a25e85ed 2021-08-17T15:20:25 [gzip] Update sources to zlib 1.2.11 This can be tested by building with the Unix development build make setup devel make or by building the freetype-demos programs with meson setup build -Dfreetype2:zlib=internal meson compile -C out and trying to run `ftview` with a `.pcf.gz` font file. * src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also remove the temporary fix introduced in commit 6a431038 to work around the fact that the internal sources were too old. * src/gzip/README.freetype: New file describing the origin of the sources and how they were modified. * src/gzip/patches/*: Patch files applied to original sources. * src/gzip/*: Updated zlib sources with the patch file(s) from `src/gzip/patches/` applied, followed by a conversion with zlib's `zlib2ansi` script.
Alexei Podtelezhnikov 49270c17 2021-09-14T21:32:43 Replace boolean allocation macros with MEM ones. * src/base/ftbitmap.c (FT_Bitmap_Copy): Use MEM-macro. * src/base/ftobjs.c (ft_glyphslot_alloc_bitmap): Ditto. * src/bzip2/ftbzip2.c (ft_bzip2_alloc): Ditto. * src/cache/ftccache.c (ftc_cache_init): Ditto * src/gzip/ftgzip.c (ft_gzip_alloc): Ditto. * src/psnames/psmodule.c (ps_unicodes_init): Ditto. * src/sfnt/sfobjs.c (sfnt_load_face): Ditto. * src/sfnt/ttload.c (tt_face_load_name): Ditto.
Werner Lemberg c2fa51d9 2021-07-24T20:32:16 Fix some `cppcheck` warnings. * src/bzip2/ftbzip2.c (ft_bzip2_file_skip_output), src/gzip/ftgzip.c (ft_gzip_file_skip_output): Reduce scope of `delta`. * src/psaux/psintrp.c, src/psaux/psintrp.h (cf2_interpT2CharString): Add `const` to `buf` parameter. * src/raster/ftraster.c (DelOld): Add `const` to `profile` parameter. (Vertical_Sweep_Span): Reduce scope of `target`. (FT_Outline_Get_CBox): Reduce scope of `xMin`, `xMax`, `yMin`, `yMax`. * src/smooth/ftgrays.c (gray_render_conic): Reduce scope of `split`. (gray_sweep, gray_sweep_direct): Reduce scope of `area`. * src/tools/apinames.c (names_dump) <OUTPUT_WATCOM_LBC>: Reduce scope of `temp`.
Ben Wagner 06e21ffe 2021-05-18T14:49:50 [gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.
Alexei Podtelezhnikov 4e1c6a12 2021-04-30T09:35:21 * src/gzip/ftgzip.c (ft_gzip_alloc): Zero out memory again.
Alexei Podtelezhnikov 1e525c62 2021-04-23T08:24:22 [bzip2,gzip] s/FT_ALLOC/FT_QALLOC/ for initialized buffers. * src/bzip2/ftbzip2.c (ft_bzip2_alloc): Do not zero out the buffer. * src/gzip/ftgzip.c (ft_gzip_alloc, FT_Stream_OpenGzip): Ditto.
Werner Lemberg b6e8a712 2021-01-17T07:18:48 Update all copyright notices.
Werner Lemberg 16586859 2020-06-13T21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.
Moazin Khatti 6a431038 2020-03-02T18:21:27 [gzip] Support `gzip' encoded header conditionally. In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used. Problem report in https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to `inflateInit2' depending on whether the system installation is being used or the internal copy.

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
Werner Lemberg 95149592 2018-05-02T20:27:48 Remove FT_CONFIG_OPTION_PIC and related code. */* [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. */*: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed.

Werner Lemberg 602be7c8 2016-12-01T11:36:37 [gzip] Improve building with external zlib (#49673). Building FreeType with external zlib 1.2.8 makes msvc 14 stop with the following error. ftgzip.c zlib-1.2.8\zlib.h(86): error C2061: syntax error: identifier 'z_const' zlib-1.2.8\zlib.h(94): error C2054: expected '(' to follow 'z_const' zlib-1.2.8\zlib.h(94): error C2085: 'msg': not in formal parameter list ... zlib-1.2.8\zlib.h(877): fatal error C1003: error count exceeds 100; stopping compilation The error happens because FreeType keeps an own copy of zlib-1.1.4 under `src/gzip'. When building `src/gzip/ftgzip.c' with FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses #include <zlib.h> which correctly finds an external `zlib.h', but `zlib.h' itself has a line #include "zconf.h" which makes Visual Studio 2015 find `src/gzip/zconf.h' while compiling the files in `src/gzip'. * src/gzip/zconf.h: Rename to... * src/gzip/ftzconf.h: ... this. * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

Werner Lemberg 37412ff9 2016-01-12T21:37:13 Don't use macro names that contain `__' [1/2]. Such macro names are reserved for both C and C++. */*: Replace macros of the form `__XXX_H__' with `XXX_H_'.
Werner Lemberg c12956e7 2015-10-09T09:38:32 * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use real stream size.
Werner Lemberg b260dc9f 2015-10-04T07:39:22 [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_input), src/gzip/ftgzip.c (ft_gzip_file_fill_input): In case of an error, adjust the limit to avoid copying uninitialized memory.
Werner Lemberg 53838ce0 2015-10-03T21:12:25 [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_output), src/gzip/ftgzip.c (ft_gzip_file_fill_output): In case of an error, adjust the limit to avoid copying uninitialized memory.
Werner Lemberg 41877539 2015-09-26T15:19:54 [bzip2, gzip, lzw] Harmonize function signatures with prototype. Suggested by Hin-Tak Leung. * src/bzip2/ftbzip2.c (ft_bzip2_stream_io), src/gzip/ftgzip.c (ft_gzip_stream_io), src/lzw/ftlzw.c (ft_lzw_stream_io): Do it.
Werner Lemberg e40e8b33 2015-09-13T08:05:50 [gzip] Fix access of small compressed files (#45937). * src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak. (ft_gzip_get_uncompressed_file): Correct byte order while reading unsigned long value. Without this change, the whole optimization of accessing small files in `FT_Stream_OpenGzip' is never executed! As a consequence, access to PCF files in general (which are normally small files) should be much improved now as originally intended.
Werner Lemberg 851e8151 2015-03-01T19:27:09 Various compiler warning fixes for `make multi'. * src/autofit/afcjk.c (af_cjk_hints_compute_blue_edges), src/autofit/aflatin.c (af_latin_hint_compute_blue_edges, af_latin_hint_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_blue_edges, af_latin2_hint_edges): Declare as `static'. * src/cache/ftccmap.c (FTC_CMAP_QUERY_HASH, FTC_CMAP_NODE_HASH): Removed.

Werner Lemberg f34f1925 2014-11-26T21:59:21 * src/*: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'. (FT_Outline_Done_Internal): Change return value for invalid `outline' parameter to `Invalid_Outline'.
Werner Lemberg dc240524 2013-08-29T17:53:24 [gzip] New function `FT_Gzip_Uncompress'. This is modeled after zlib's `uncompress' function. We need this for WOFF support. * include/freetype/ftgzip.h, src/gzip/ftgzip.c (FT_Gzip_Uncompress): New function. * src/gzip/rules.mk: Rewrite to better reflect dependencies.
Werner Lemberg 3f6e0e0c 2013-06-07T18:10:40 Add and improve pragmas for MSVC compiler. * include/freetype/internal/ftdebug.h: Remove pragmas. * include/freetype/internal/ftserv.h: Use push and pop for pragmas. * include/freetype/internal/ftvalid.h: Handle warning C4324. * src/base/ftobjs.c: Use push and pop for pragmas. * src/gzip/ftgzip.c: Handle warning C4244.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Vinnie Falco 26dfeb6d 2012-03-08T06:04:03 Prepare source code for amalgamation. * src\autofit\aferrors.h, src\bdf\bdferror.h, src\bzip2\ftbzip2.c, src\cache\ftcerror.h, src\cff\cfferrs.h, src\cid\ciderrs.h, src\gxvalid\gxverror.h, src\gzip\ftgzip.c, src\lzw\ftlzw.c, src\otvalid\otverror.h, src\pcf\pcferror.h, src\pfr\pfrerror.h, src\psaux\psauxerr.h, src\pshinter\pshnterr.h, src\psnames\psnamerr.h, src\raster\rasterrs.h, src\sfnt\sferrors.h, src\smooth\ftsmerrs.h, src\truetype\tterrors.h, src\type1\t1errors.h, src\type42\t42error.h, src\winfonts\fnterrs.h: Add #undef FT_ERR_PREFIX before #define FT_ERR_PREFIX.

suzuki toshiya e62c876b 2011-06-15T02:48:33 Fix g++4.6 compiler warnings in module drivers. The background is same with previous commit. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Init `points'. (TT_Vary_Get_Glyph_Deltas): Init `delta_xy'.

Kan-Ru Chen 21b1a0de 2011-04-12T09:26:43 Fix reading of signed integers from files on 64bit platforms. Previously, signed integers were converted to unsigned integers, but this can fail because of sign extension. For example, 0xa344a1eb becomes 0xffffffffa344a1eb. We now do the reverse which is always correct because the integer size is the same during the cast from unsigned to signed. * include/freetype/internal/ftstream.h, src/base/ftstream.c (FT_Stream_Get*): Replace with... (FT_Stream_GetU*): Functions which read unsigned integers. Update all macros accordingly. * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.
Werner Lemberg c8f5b98b 2010-07-12T21:13:22 Remove C++ warnings. */*: Initialize pointers where necessary to make g++ happy.
Werner Lemberg f765e440 2010-06-24T10:34:29 */*: Use module specific error names where appropriate.

David Turner 281679de 2006-05-17T13:34:21 * include/freetype/internal/tttypes.h, src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c, src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c, src/type1/t1gload.c: this is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.
David Turner de271ab8 2006-02-25T14:53:02 * builds/unix/ftsystem.c, include/freetype/config/ftheader.h, include/freetype/internal/services/svotval.h, include/freetype/internal/services/svpfr.h, src/base/ftsystem.c, src/bdf/bdfdrivr.c, src/cache/ftcbasic.c, src/cff/cffcmap.c, src/gzip/ftgzip.c, src/lzw/ftlzw.c, src/lzw/ftlzw2.c, src/psaux/t1cmap.c, src/sfnt/ttbdf.c, src/smooth/ftgrays.c: solved -Wmissing-prototypes warnings with GCC

David Turner 6a681fa8 2006-01-27T12:11:22 * src/autofit/afwarp.c: simple #ifdef to prevent compilation when the warp hinter isn't active (it shouldn't, still experimental) * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid" and "otvalid" from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the "ftvalid" CVS module. note also that current Make-based build system still compiles the modules though... * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING, which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. this macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: disable macro to use the memory debugger. this will be fixed later !!
Werner Lemberg ebf5585d 2005-03-16T01:49:54 Formatting.
David Turner 68df4f73 2005-03-15T18:18:57 * src/bdf/bdflib.c: various improvements to the bdf loader, mainly used to reduce the amount of heap size required to only test wether we're dealing with a BDF font (the old code allocated 64 Kb right before any test). * src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check the LZW header before doing anything else. This helps avoid un-necessary heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !) * src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder, though the code savings is smaller.

Werner Lemberg dfa46199 2004-03-05T09:26:24 * Jamfile, vms_make.com, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype/vcproj, include/freetype/ftmoderr.h: Add LZW module. * Jamfile.in: Removed. * docs/CHANGES: Updated. * include/freetype/internal/ftobjs.h: s/MIN/FT_MIN/, s/MAX/FT_MAX/, s/ABS/FT_ABS/. Updated all callers. * src/type1/t1load.c (parse_dict), src/pcf/pcfdrivr.c (PCF_Face_Init): Use FT_ERROR_BASE. Add support for PCF fonts compressed with LZW (extension .pcf.Z, created with `compress'). * include/freetype/config/ftoption.h, devel/ftoption.h (FT_CONFIG_OPTION_USE_LZW): New macro. * include/freetype/ftlzw.h: New file. * include/freetype/config/ftheader.h (FT_LZW_H): New macro for ftlzw.h. * src/lzw/*: New files. * src/pcf/pcfdrivr.c: Include FT_LZW_H. (PCF_Face_Init): Try LZW also. * src/gzip/ftgzip.c: s/0/Gzip_Err_Ok/ where appropriate. Beautify.
Werner Lemberg 779afe4b 2003-06-22T15:33:53 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in computation of glyph_index. (FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Size): Assign value to `metrics' after validation of arguments. Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/.
Werner Lemberg a7d6b4da 2003-06-09T20:55:04 * src/gzip/ftgzip.c: (inflate_mask): Replaced with... (NO_INFLATE_MASK): This. * src/gzip/infutil.h: Declare `inflate_mask' conditionally by NO_INFLATE_MASK.
Werner Lemberg 0240d29c 2003-06-09T15:54:18 * src/gzip/ftgzip.c (ft_gzip_file_fill_output): Handle Z_STREAM_END correctly. * src/pshinter/pshglob.c (psh_globals_new): Change calculation of dim->stdw.count to avoid compiler problem. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Move the block variables to the beginning of the function to avoid compiler problems. Add casts necessary for 16bit compilers. * src/pfr/rules.mk (PFR_DRV_SRC): Add pfrsbit.c. (PFR_DRV_H): Add pfrtypes.h. * include/freetype/config/ftconfig.h: s/__MWKS__/__MWERKS__/. * src/pfr/pfrsbit.c (pfr_bitwriter_init): Change type of third argument to FT_Bool. (pfr_lookup_bitmap_data): Change type of third and fourth argument to FT_UInt. Updated caller. (pfr_load_bitmap_bits): Change type of fourth argument to FT_Bool.
Werner Lemberg 756655bd 2003-06-07T05:13:22 * src/base/ftmac.c (FT_New_Face_From_SFNT): s/rlen/sfnt_size/ to make it compile. * include/freetype/internal/psaux.h, src/truetype/ttgload.h: s/index/idx/ to fix compiler warnings. * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Use more `volatile' to fix compiler warning. * src/gzip/ftgzip.c (BUILDFIXED): Removed. * src/gzip/inftrees.c (inflate_trees_fixed) [!BUILDFIXED]: Use FT_UNUSED to remove compiler warning.
Werner Lemberg f79a7ae0 2003-05-21T21:47:25 * src/gzip/ftgzip.c (ft_gzip_fil_io): Revert change from yesterday; it has already been fixed differently. * src/truetype/ttinterp.c (DO_SFVTL): Add missing braces around if-clause.
Werner Lemberg 77c34b82 2003-05-20T22:06:38 * t1load.c (parse_blend_axis_types): Fix compiler warning. * src/gzip/ftgzip.c (ft_gzip_file_io): Avoid zero value of `delta' to prevent infinite loop. * docs/VERSION.DLL: Provide better autoconf snippet to check FreeType version. * src/base/ftobjs.c (open_face): Free `internal' not `face->internal' in case of error to avoid possible segfault. * src/pshinter/pshalgo3.c (ps3_hints_apply): Check whether we actually have an outline.
Werner Lemberg 428c2e4f 2003-04-25T05:35:04 * src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first argument. (bdf_get_font_property): Use `const' for third argument. Updated all callers. * src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height similar to the PCF driver. * src/bdf/bdf.h (_hashnode): Use `const' for `key'. Updated. * src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask' is declared twice. It is perhaps better to modify the zlip source files directly instead of this hack. (zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts to make build with g++ successful.
Werner Lemberg 917a5937 2003-04-23T07:13:54 * src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]: Convert K&R format to modern C usage. (FT_Stream_OpenGzip): Use long constant. Cleanups.
David Turner a3c37802 2003-02-28T08:32:46 * src/gzip/ftgzip.c (ft_gzip_file_done): fixed memory leak, the ZLib stream was not properly finalized
David Turner 229d122e 2003-02-25T19:20:12 * src/gzip/ftgzip.c: fixed a bug that caused FreeType to loop endlessly when trying to read certain compressed gzip files. The following test could be used to reveal the bug: touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz * src/pfr/pfrobjs.c, src/pfr/pfrload.c, src/pfr/pfrtypes.h: several fixes to the PFR font driver: - the list of available embedded bitmaps was not correctly set in the root FT_FaceRec structure describing the face - the glyph loader always tried to load the outlines when FT_LOAD_SBITS_ONLY was specified - the table loaded now scans for *undocumented* elements of a physical font's auxiliary data record, this is necessary to retrieve the "real" family and style names. NOTE THAT THIS CHANGES THE FAMILY NAME OF MANY PFR FONTS !!
David Turner 4bdf4350 2003-01-30T23:24:18 various improvements for 2.1.4. see ChangeLog, I've got problems with copy & paste on my desktop !!
David Turner 619d62d9 2003-01-15T23:01:02 * src/gzip/ftgzip.c: bugfix: couldn't read certain gzip-ed font files
David Turner 621e4886 2002-12-16T21:51:24 2002-12-16 David Turner <david@freetype.org> * docs/VERSION.DLL: updating document to better explain the differences between the three version numbers being used on Unix, as well as provide the AutoConf fragment provided by Lars Clausen * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that prevented bezier arcs with negative vertical coordinates to be rendered appropriately 2002-11-27 Vincent Caron <v.caron@zerodeux.net> * builds/unix/unix-def.in, builds/unix/freetype-config.in, builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c: adding support for system zlib installations when available on the target platform (Unix only)
David Turner 60b32e16 2002-11-06T22:32:54 2002-11-05 David Turner <david@freetype.org> * include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify the use of system-wide zlib. Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore. This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings in optimized mode relative to the "volatile" local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same than a volatile pointer to a variable :-) the fix was to change "volatile FT_Byte* p" into "FT_Byte* volatile p" * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed compiler warnings in optimized modes * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting any zlib function names outside of the component. This prevents linking problems on some platforms, when applications want to link FreeType _and_ ZLib together. 2002-11-05 Juliusz <jch@pps.jussieu.fr> * src/psaux/psobjs.c (ps_table_add): modified increment loop in order to implement exponential behaviour
David Turner 54b0bca5 2002-10-31T22:19:27 * include/freetype/ftgzip.h, src/gzip/ftgzip.c: adding support for gzip compressed streams !! * src/pcf/pcfdriver.c: adding automatic support for gzip-compressed PCF files
