The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++. (FT_UNUSED): Define here instead of... * include/freetype/config/compiler-macros.h: ... here. (FT_FUNCTION_DECLARATION): Remove special definition for C++. (FT_LOCAL_ARRAY_DEF): Fix definition. * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h, src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'. 2020-07-06 David Turner <[email protected]> [build] Fix multi and C++ builds. The following builds were failing due to previous changes: make multi make multi CC="c++" * include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'. * include/freetype/config/ftheader.h (FT_BEGIN_HEADER, FT_END_HEADER): Protect against redefinition. * src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h, src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h, src/sfnt/woff2tags.h: Include `compiler-macros.h'. * src/sfnt/woff2tags.c: Include `woff2tags.h'. 2020-07-06 Werner Lemberg <[email protected]> [psaux] Improve `t1_decoder_parse_metrics' (#58646). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function to handle `op_callsubr' and `op_return'. 2020-07-05 David Turner <[email protected]> [build] Improve visibility support of library function names. * include/freetype/config/public-macros.h (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as public (and thus exportable). (FT_EXPORT): Use it. * include/freetype/config/compiler-macros.h (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as internal to the library (and thus hidden). Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros. 2020-07-05 David Turner <[email protected]> [build] Split off more stuff from `ftconfig.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/*.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed. 2020-07-05 David Turner <[email protected]> [build] Move mac support code to `mac-support.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off mac-specific stuff to... * include/freetype/config/mac-support.h: ...this new file. * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> #undef' string replacement; the affected code is no longer part of the `ftconfig.h' template. 2020-07-05 David Turner <[email protected]> [build] Put integer type definitions into `integer-types.h'. Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path. 2020-07-05 David Turner <[email protected]> [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'. Since we are no longer limited to 8.3 file names, it is simpler to follow the usual conventions for template files. * builds/unix/ftconfig.in: Renamed to... * builds/unix/ftconfig.h.in: ...this. * CMakeLists.txt, builds/unix/configure.raw: Updated. 2020-07-03 Alexei Podtelezhnikov <[email protected]> [smooth] Introduce direct oversampling for overlaps. This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them. 2020-07-03 Alexei Podtelezhnikov <[email protected]> [smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function. 2020-07-03 Alexei Podtelezhnikov <[email protected]> [smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's. 2020-06-20 Sebastian Rasmussen <[email protected]> [cff] Fix handling of `style_name == NULL' (#58630). * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails by returning NULL in `cff_face_init', `remove_style' is still called. This means that the NULL pointer is dereferenced, causing a crash. 2020-06-19 Sebastian Rasmussen <[email protected]> [cff] Fix another two memory leaks (#58629). * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' fails to allocate one of the `internal->subfont' variables, make sure to free `internal->topfont' and any successfully allocated subfonts. 2020-06-19 Sebastian Rasmussen <[email protected]> [psaux] Fix memory leak (#58626). * src/psaux/psstack.c (cf2_stack_init): If `cf2_stack_init' fails to allocate the stack, return error early. 2020-06-19 Sebastian Rasmussen <[email protected]> [base] Fix memory leak (#58624). * src/base/ftobjs.c (FT_New_Size): Avoid trying to free `size->internal' unless `size' has been allocated. This mistake appeared in the fix for issue #58611. 2020-06-19 Alexei Podtelezhnikov <[email protected]> [base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines. 2020-06-19 Sebastian Rasmussen <[email protected]> [cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'. 2020-06-19 Werner Lemberg <[email protected]> [base] Fix UBSAN error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23166 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Avoid values larger than 32 bits. 2020-06-19 Werner Lemberg <[email protected]> [woff2] Fix segfault. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23402 * src/sfnt/sfwoff2.c (get_x_mins): Check whether `loca' table exists. 2020-06-19 Stephen McDowell <[email protected]> [sfnt] Support Intel compilers. * src/sfnt/pngshim.c (premultiply_data): Intel compilers do not currently support `__builtin_shuffle'. 2020-06-19 Sebastian Rasmussen <[email protected]> [base] Fix memory leak (#58611). * src/base/ftobjs.c (FT_New_Size): When the call to `clazz->init_size' fails, make sure to free `size->internal'. 2020-06-19 Sebastian Rasmussen <[email protected]> [cff] Fix memory leak (#58610). * src/cff/cffobjs.c (cff_size_init): When the call to `funcs->create' fails, make sure to free `internal'. 2020-06-19 Werner Lemberg <[email protected]> * src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'. 2020-06-19 Sebastian Rasmussen <[email protected]> [cff] Free table upon error allocating other data (#58609). * src/cff/cffload.c (cff_index_get_pointers): When new_bytes fails to allocate, make sure to free the table. Do the same for both allocations if there is a later error. 2020-06-13 Werner Lemberg <[email protected]> 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'. 2020-06-08 David Turner <[email protected]> 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. 2020-06-02 Werner Lemberg <[email protected]> * src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps. 2020-05-18 David Turner <[email protected]> Remove obsolete HAVE_STDINT_H probing macro. This macro was updated by the unix configure script and the `CMakeLists.txt' one, but is never used in the source tree (nor is <stdint.h> included anywhere). * CMakeLists.txt, builds/unix/ftconfig.in: Don't handle `HAVE_STDINT_H'. 2020-05-18 David Turner <[email protected]> Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete. 2020-05-12 Alexei Podtelezhnikov <[email protected]> [smooth] Turn on LCD filtering during FreeType initialization. * src/smooth/ftsmooth.c (ft_smooth_init): Enable LCD filtering. * include/freetype/ftlcdfil.h: Document it, remove patent warnings. * include/freetype/freetype.h (FT_Render_Mode): Updated. * include/freetype/config/ftoption.h, devel/ftoption.h [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Do not mention patents. 2020-05-11 Alexei Podtelezhnikov <[email protected]> [smooth] Stop using dedicated LCD modules and classes. The LCD modules were never truly independent. They mostly served as a way to disable patented LCD rendering, which is no longer necessary. The `smooth' module now handles LCD modes as well. * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class. ft_smooth_lcdv_renderer_class): Deleted. (ft_render_smooth): Reworked from `ft_render_smooth_generic'. * src/smooth/ftsmooth.h: Remove dedicated LCD classes. * src/smooth/module.mk: Remove dedicated LCD modules. * include/freetype/config/ftmodule.h: Ditto. * builds/amiga/include/config/ftmodule.h: Ditto. * include/freetype/ftmodapi.h: Do not mention LCD modules. 2020-05-09 Werner Lemberg <[email protected]> * Version 2.10.2 released. ========================== Tag sources with `VER-2-10-2'. * docs/VERSION.TXT: Add entry for version 2.10.2. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.10.1/2.10.2/, s/2101/2102/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 2. * builds/unix/configure.raw (version_info): Set to 23:2:17. * CMakeLists.txt (VERSION_PATCH): Set to 2. * docs/CHANGES: Updated. 2020-05-08 Jakub Alba <[email protected]> * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000. 2020-05-03 Alexei Podtelezhnikov <[email protected]> * builds/freetype.mk: Refactor for readability. 2020-05-02 Alexei Podtelezhnikov <[email protected]> [builds] Clean up Windows CE project files. Remove version from filenames that caused a lot of polution in the release process. Use VERSIONINFO resource instead. * builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2008-ce/freetype.vcproj, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/freetype.dsp: s/2101//g, but add `ftver.rc'. * builds/wince/vc2008-ce/index.html, builds/wince/vc2005-ce/index.html, builds/windows/visualce/index.html: s/2101//g. 2020-05-01 Alexei Podtelezhnikov <[email protected]> * devel/ft2build.h: Override FT_CONFIG_MODULES_H here as well. 2020-05-01 Alexei Podtelezhnikov <[email protected]> [builds/unix] Consolidate marco overrides (for the demos to see them). * builds/unix/unix-cc.in (FT_CONFIG_MODULES_H, FT_CONFIG_OPTIONS_H): Override them here... * builds/freetype.mk: ... instead of here. 2020-04-08 Werner Lemberg <[email protected]> Allow setting `CC' in Unix build (#58051). * builds/unix/unix-cc.in (CC): Use `override'. The command line value of `CC' (if any) is stored already in `CCraw'. 2020-04-04 Nikhil Ramakrishnan <[email protected]> [woff2] Return if single stream operation fails. * src/sfnt/sfwoff2.c (get_x_mins): Do it. * src/sfnt/woff2tags.c: Remove unused include. 2020-03-22 Nikhil Ramakrishnan <[email protected]> [docs] Fix building docs if `srcdir' != `builddir'. `docs/reference/*' was moved one directory up in commit 237fed6. * builds/unix/unix-def.in (PIP): Remove variable. * configure: Create `docs' directory and copy assets from `docs/markdown'. * docs/README: Output directory is `reference'. 2020-03-21 Nikhil Ramakrishnan <[email protected]> [docwriter] Drop support for Python < 3.5. Python versions < 3.5 have reached end-of-life and as such, no security or bug fixes will be provided for those versions. See https://devguide.python.org/#status-of-python-branches for more information. * Jamfile (RefDoc): Add `site' parameter. * builds/detect.mk (std_setup): Update Python version requirement. * builds/freetype.mk (refdoc-venv): Use pip as `python -m pip'. * builds/unix/ax_compare_version.m4, builds/unix/ax_prog_python_version.m4: Macros to detect Python version. New files. * builds/unix/configure.raw: Check for Python >= 3.5 and remove check for `pip'. * docs/CHANGES, docs/INSTALL.GNU, docs/README: Updated. 2020-03-02 Moazin Khatti <[email protected]> [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. 2020-02-29 Ben Wagner <[email protected]> [truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure. 2020-03-01 Nikhil Ramakrishnan <[email protected]> [docs] Update docwriter stylesheet. This change is required to support docwriter 1.2.1. See https://github.com/freetype/docwriter/issues/36 for more information. * docs/markdown/stylesheets/extra.css: (.md-typeset code) -> (.md-typeset pre>code) (pre) -> (pre>code) (p, .md-typeset p, h4): Remove commented styles. (table.index): Remove unused styles. 2020-02-28 Ben Wagner <[email protected]> [truetype] Add better checks for loading `gvar' table (#57905). * src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any `blend->xxxcount' values until the corresponding data has been checked. Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message. 2020-02-27 Werner Lemberg <[email protected]> Make `FT_HAS_*' and `FT_IS_*' really return true (#57906). * include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Implement it. 2020-02-25 Dominik Röttsches <[email protected]> Fix for CFF space glyph regression (#57541). * src/psaux/psft.c (cf2_decoder_parse_substrings): Replace early-out with FT_OFFSET. 2020-02-22 Werner Lemberg <[email protected]> [woff2] Fix font table access. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20778 * src/sfnt/sfwoff2.c (get_x_mins): Explicitly check for presence of `head' table, which might not have been processed yet. 2020-02-21 Werner Lemberg <[email protected]> [psaux] Make `t1_decoder_parse_metrics' handle `op_div' (#57519). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function. 2020-02-19 Nikolaus Waxweiler <[email protected]> [autofit] Add support for Hanifi Rohingya script. * src/autofit/afblue.dat: Add blue zone data for Hanifi Rohingya. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Hanifi Rohingya standard character. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Hanifi Rohingya data. 2020-02-19 Werner Lemberg <[email protected]> Require HarfBuzz 1.8. * builds/unix/configure.raw, CMakeLists.txt: Request HarfBuzz 1.8.0 or newer. We are going to add auto-hinter support for Hanifi Rohingya, which was introduced in Unicode 11.0. 2020-02-12 Werner Lemberg <[email protected]> * src/sfnt/ttcmap.c (tt_face_build_cmaps): Ignore version (#57708). 2020-02-04 Werner Lemberg <[email protected]> * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001. 2020-01-04 Werner Lemberg <[email protected]> [base] Fix `FREETYPE_PROPERTIES=type1:hinting-engine=adobe`. * src/base/ftpsprop.c (ps_property_set) [hinting-engine]: Avoid an incorrect return value that caused a warning. The function did the right thing, though. 2020-01-03 Werner Lemberg <[email protected]> [woff2] Fix memory leaks and a runtime warning. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19773 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=18101 * src/sfnt/sfwoff2.c (compute_ULong_sum): Add missing cast. (reconstruct_hmtx): Add missing deallocation calls. 2020-01-02 Dominik Röttsches <[email protected]> [truetype] Fix UBSan warning on offset to nullptr (#57501). * src/truetype/ttinterp.c (Ins_CALL): Fail if `exc->FDefs' is null. 2019-12-31 Nikhil Ramakrishnan <[email protected]> [woff2] Allow bitmap-only fonts (#57394). * src/sfnt/sfwoff2.c (reconstruct_font): Fix test for `glyf' and `loca' tables. 2019-12-21 Hugh McMaster <[email protected]> [docs] (2/2) Fix generation of API documentation (#56745). Creating the API Reference in the (new) `reference' sub-directory is consistent with other documentation sub-topics, such as `design', `glyphs' and `tutorial'. This patch fixes broken hyperlinks in the documentation pointing to and from the API Reference. It also allows web assets to load from their relative paths. * builds/freetype.mk (DOC_DIR): Adjust. (refdoc, refdoc-venv): Add `--site' argument. * builds/toplevel.mk (do-dist): Updated. 2019-12-21 Hugh McMaster <[email protected]> [docs] (1/2) Move static web assets (#56745). * docs/reference/*: Move ... * docs: ... one directory up. 2019-12-21 Dominik Röttsches <[email protected]> Fix more UBSan warnings on adding offset to nullptr (#57432). * src/truetype/ttinterp.c (Ins_LOOPCALL), src/psaux/psft.c (cf2_initLocalRegionBuffer): Use `FT_OFFSET'. 2019-12-16 Werner Lemberg <[email protected]> [truetype] Fix UBSan warnings on adding offsets to nullptr.

This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'.

We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables. (woff2_open_font): Updated. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Handle TTCs and start reconstructing font. We `handle' TTCs by modifying the `indices' array to point to only those tables that are part of the requested `face_index'. Set and use `num_tables' in `WOFF2_TtcFont'. * src/sfnt/sfwoff2.c (reconstruct_font): New function. (woff2_open_font): Start reconstruction of font. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Get known tags from function. Change `KnownTags' to a function (`woff2_known_tags'). This avoids introducing a global constant array. This function returns the specified index without *any* checks. The caller must ensure that `index' is within array limits. * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' notation to `woff2_known_tags( ... )'. * src/sfnt/woff2tags.c: Perform changes. * src/sfnt/woff2tags.h: Update definitions. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'. 2019-08-27 Nikhil Ramakrishnan <[email protected]> [woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'.

The same as previous commit but for the old engine. * src/psaux/t1decode.c (t1operator_seac): Implement it. 2019-07-04 Chris Liddell <[email protected]> [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. 2019-07-01 Werner Lemberg <[email protected]> * Version 2.10.1 released. ========================== Tag sources with `VER-2-10-1'. * docs/VERSION.TXT: Add entry for version 2.10.1. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.10.0/2.10.1/, s/2100/2101/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 23:1:17. * CMakeLists.txt (VERSION_PATCH): Set to 1. * include/freetype/fterrors.h (FT_Error_String): Fix C++ compilation. 2019-06-26 Alexei Podtelezhnikov <[email protected]> * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Fix inequality.

Update copyright notices. 2019-04-29 Alexei Podtelezhnikov <[email protected]> [smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. The new algorithm produces slightly larger number of splits, which is compensated by its simplicity. The overall rendering performance is improved by 1-2%. The larger number of splits does not necessarily result in higher quality, which stays comparable. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition. 2019-04-26 Alexei Podtelezhnikov <[email protected]> [smooth] Bithacks and cosmetics. * src/smooth/ftgrays.c (gray_record_cell, gray_set_cell, gray_hline, gray_render_conic, gray_convert_glyph_inner): Updated. 2019-04-25 Alexei Podtelezhnikov <[email protected]> Optimize Bézier bisections.

Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected.

For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines.

AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them.

This is the option making Sun / Oracle C compilers hide the symbols from global scope. * include/freetype/config/ftconfig.h: Use "__global" prefix for FT_EXPORT() macro, if SunPro C is newer than Sun ONE Studio 8 (2003). * builds/unix/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. 2018-05-02 Nikolaus Waxweiler <[email protected]> Unbreak CMake Windows installation * CMakeLists.txt: Generate ftconfig.h on non-UNIX. 2018-05-02 Werner Lemberg <[email protected]> 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. ---------------------------------------------------------------------------- Copyright (C) 2018-2020 by David Turner, Robert Wilhelm, and Werner Lemberg.
