Alexei Podtelezhnikov 5b7e45ac 2023-07-27T15:06:38 [truetype] Remove Infinality for good. Remove everything `#ifdef TT_SUPPORT_SUBPIXEL_HINTING_INFINALITY`, which was undefined for a while now. * include/freetype/internal/tttypes.h: Ditto. * src/truetype/truetype.c: Ditto. * src/truetype/ttdriver.c: Ditto. * src/truetype/ttgload.c: Ditto. * src/truetype/ttinterp.c: Ditto. * src/truetype/ttinterp.h: Ditto. * src/truetype/ttobjs.c: Ditto. * src/truetype/ttsubpix.[ch]: Remove files. * src/truetype/rules.mk: Don't mention "ttsubpix.c".
Jouk Jansen 9e3c5d7e 2023-07-21T21:36:57 * vms_make.com: Provide separate library compiled with C++. Some types on OpenVMS x86_64 (for example, `long') have different sizes depending on whether compiled with either C or C++. In particular, X-Windows applications crash if linked with the C++ version. This patch makes `vms_make.com` create a second version of the FreeType library compiled with C++ if OpenVMS is running on the x86_64 platform.
Jouk Jansen f7ae7e88 2023-07-21T21:33:20 * vms_make.com: Fix typos.
Jouk Jansen 7c542d02 2023-07-21T21:31:28 * src/smooth/ftgrays.c (FT_SSE2): Fix definition for VMS.
Jouk Jansen 5769f13a 2023-07-19T13:37:48 vms_make.com: Make use of additional libraries optional. Check whether `.olb` files are present. Also check for the HarfBuzz library.
Jouk Jansen e8aa5af9 2023-07-19T13:34:45 vms_make.com: Add `/warn=noinfo` to `CFLAGS`. This reduces enormously the informationals while compiling on x86_64 (i.e., which `.h` file is inluded form where).
Ben Wagner dd3c9c5f 2023-07-18T13:25:57 [woff2] Clean up on large brotli expansion * src/sfnt/sfwoff2.c (woff2_open_font): set error and goto cleanup Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60711
Werner Lemberg 336503df 2023-07-16T07:36:01 [woff2] Avoid allocation bomb. This is a fix for commit 85167dbd5, reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60615 * src/sfnt/sfwoff2.c (MAX_SFNT_SIZE): New macro. (woff2_open_font): Use it to limit the maximum size of an uncompressed WOFF2 font.
Werner Lemberg 3c92e7bf 2023-07-14T18:58:55 [cff] Fix compiler warning. * src/cff/cffparse.c, src/cff/cffparse.h: Make `cff_parse_fixed` a local function.
Ben Wagner 85167dbd 2023-07-13T16:49:34 [woff2] Remove sfnt size guess check In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value is now just a hint and a conforming implementation must not reject otherwise valid data if the `totalSfntSize` turns out not to be exact. * src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed woff2 data would fit in the sfnt size guess. Fixes: #1235
Skef Iterum 26a7f047 2023-07-11T01:40:25 [cff] Make blend operator work with floats in private dicts. The CFF2 blend operator takes N default values and corresponding sets of deltas and pushes N values specific to a designspace location. CFF has a floating point numeric type and the FreeType blending code was not converting those into its internal 16.16 Fixed type format. Fixes #1243. * src/cff/cffparse.c (do_fixed): Handle floating point numbers. Also fix scaling overflow check for integer-to-fixed conversion. * src/cff/cffload.c (cff_blend_doBlend): Updated.
Hin-Tak Leung dec2743e 2023-07-07T19:24:48 * src/truetype/ttgload.c (TT_Hint_Glyph): More mostly cosmetic update. This is a follow-up to commit 49c74ac02, which creates a new local variable "exec = loader->exec", and shortening a lot of "loader->exec". This commit does two more such changes missed in that first commit. Signed-off-by: Hin-Tak Leung <htl10@users.sourceforge.net>
Hugh McMaster 355e9197 2023-07-06T21:07:16 [gzip] Don't compile internal zlib development files when using system zlib. `src/gzip/rules.mk` compiles the internal zlib sources even when using the zlib development files provided by a host system. If the internal zlib development files are not present, FreeType fails to build from source. This patch ensures the internal zlib development files are only prerequisites when not using zlib development files on a host system. * src/gzip/rules.mk (GZIP_DRV_SRCS): Define conditionally.
Werner Lemberg e4586d96 2023-06-24T05:18:54 * Version 2.13.1 released. ========================== Tag sources with `VER-2-13-1'. * docs/VERSION.TXT: Add entry for version 2.13.1. * docs/CHANGES: Updated. * docs/release, docs/README, builds/macs/README: Updated. * README, 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/2.13.0/2.13/1/, s/2130/2131/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 26:0:20. * CMakeLists.txt (VERSION_PATCH): Set to 1. * subprojects/libpng.wrap, subprojects/zlib.wrap, subprojects/dlg: Updated.
suzuki toshiya 5c00a468 2023-05-17T01:29:40 Comment fixes.
Werner Lemberg 86d0ca24 2023-06-09T05:13:47 [sdf] Correct handling of empty glyphs. This is a refinement of commit 7b3ebb9. * src/sdf/ftsdfrend.c (ft_sdf_render): Goto 'Exit' instead of directly returning. (fd_bsdf_render): Ditto, also taking care of setting `FT_GLYPH_OWN_BITMAP` correctly.
Ben Wagner 4e1c0e8f 2023-06-05T11:53:34 Mark FT_Renderer_Class::raster_class as pointer to const The `FT_DEFINE_RASTER_FUNCS` macro declares a `const FT_Raster_Funcs`. The address of the definition is taken and assigned to `FT_Renderer_Class::raster_class` which is currently `FT_Raster_Funcs*`. Until recently the `const` was cast away and with the removal of the cast there are now warnings about dropping this `const`. Instead of adding back the casts, make `FT_Renderer_Class::raster_class` a pointer to const, as is done with pointers in other interfaces. * include/freetype/ftrender.h (FT_Renderer_Class_): mark `raster_class` as const.
Ben Wagner 7bed7a02 2023-06-01T21:05:32 Fix some `FT_Fixed` vs. `FT_Long` confusion. `FT_Fixed` and `FT_Long` are both typedef'ed to be `signed long`. However, `FT_Fixed` implies that the lower 16 bits are being used to express fractional values and so these two types should not be confused. * include/freetype/internal/services/svmm.h (FT_Set_MM_Blend_Func): Use `FT_Fixed` for `coords`. Users are passing `FT_Fixed` and implementations are taking `FT_Fixed`. (FT_Get_MM_Blend_Func): Ditto. * src/autofit/afcjk.c (af_cjk_metrics_check_digits): Use `FT_Long` for `advance` and `old_advance`. `advance`'s address is passed as `FT_Long*` to `af_shaper_get_elem`, which writes the advance in em units (not fixed). The exact value is not important here as it is only compared to check whether it has changed. * src/autofit/aflatin.c (af_latin_metrics_check_digits): Ditto.
Ben Wagner 2fb8eda5 2023-06-01T19:38:36 */*: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type.
Werner Lemberg b641b607 2023-06-03T06:09:30 Minor formatting.
Werner Lemberg 80a507a6 2023-05-23T13:13:56 Replace `sprintf` with `snprintf`. Fixes #1233. * include/freetype/config/ftstdlib.h (ft_sprintf): Replace with... (ft_snprintf): This new macro. * src/autofit/afhints.c (af_print_idx): Add argument to pass the buffer size. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Updated. * src/bdf/bdflib.c (BUFSIZE): New macro. (bdf_parse_properties_, bdf_parse_start_): Use `ft_snprintf`. * src/tools/ftrandom/ftrandom.c (do_test): Use `snprintf`.
Werner Lemberg 66cc4619 2023-05-23T12:54:48 docs/DEBUG: Formatting.
suzuki toshiya 562f3481 2023-05-20T12:52:25 [doc] Type1 GX (sfnt-wrapped Type1) is not supported. * docs/formats.txt: Clarify the reference of Type1 GX, and state that this format is not supported. This is because the content `TYP1' table is not exactly same with the Type1 font format specification; no eexec encryption is used. For detail and concrete examples, see the analysis on: https://gitlab.freedesktop.org/freetype/freetype/-/issues/1231
Craig White 2342a03a 2023-05-19T14:11:57 Add missing end quote of a string in the example code of FT_Trace_Set_Level
Seigo Nonaka 115e9275 2023-05-19T12:11:45 [truetype] Reduce heap allocation of `deltaSet` variation data. `deltaSet` is an array of packed integers that can be 32 bits, 16 bits, or 8 bits. Before this change, these values were unpacked to 32-bit integers. However, this can cause big heap allocations, e.g., around 500 KByte for 'NotoSansCJK'. To reduce this amount, store the packed integers and unpack them just before passing to the calculation. At calculation time, due to the variable length of region indices, temporary heap allocations are necessary. This heap allocation is not negligible and visible in `ftbench` results. So, use stack-allocated arrays for short array calculations. Fixes #1230. * include/freetype/internal/ftmmtypes.h (GX_ItemVarDataRec): New fields `wordDeltaCount` and `longWords`. * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Load packed data. (tt_var_get_item_delta): Unpack data before applying.
Jouk Jansen 99dadd56 2023-05-17T12:40:59 vms_make.com: Create shared executable for x86 version of OpenVMS.
Werner Lemberg 416d4c25 2023-05-15T15:44:36 Add new load flag `FT_LOAD_NO_SVG`. Modern color fonts often contain both an 'SVG' and 'COLR' table. FreeType always preferred 'SVG' over 'COLR' (this was a design decision), however, this might not be the right choice for the user. The new flags makes FreeType ignore the 'SVG' table while loading a glyph. Fixes #1229. * include/freetype/freetype.h (FT_LOAD_NO_SVG): New macro. * src/base/ftobjs.c (FT_Load_Glyph), src/cff/cffgload.c (cff_slot_load), src/truetype/ttgload.c (TT_Load_Glyph): Use it.

Alexei Podtelezhnikov ad708d70 2023-05-11T17:41:49 [cache] Revise the dynamic hash table accounting. Instead of counting entries relative to the middle of the hash table, this switches to the absolute counter with the full index range mask. As a result, some calculations become a bit simpler. The cache resizing logic stays largely the same. * src/cache/ftccache.h (FTC_NODE_TOP_FOR_HASH): Revised with new counter. * src/cache/ftccache.c (ftc_get_top_node_for_hash): Ditto. (ftc_cache_resize): Simplify reallocations and stop their zeroing. (ftc_cache_init): Stop over-allocating but keep zeroing initially. (FTC_Cache_Clear, FTC_Cache_RemoveFaceID): Updated accordingly.
suzuki toshiya 6ca0a935 2023-05-11T14:31:23 [t1cid] Set FT_FACE_FLAG_CID_KEYED. * cidobjs.c (cid_face_init): Set FT_FACE_FLAG_CID_KEYED. * cidriver.c (cid_get_is_cid): Comment about the case that is_cid cannot guarantee the glyph collection specification.

Werner Lemberg e02a40a4 2023-05-08T20:12:26 * src/cff/cffdrivr.c (cff_glyph_load): Fix guard for `size`. This was forgotten to change in commit 2b54eba36b (in May 2004). Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=58739
Werner Lemberg 5edd6d52 2023-05-08T07:22:59 Minor compiler warning fixes. * src/autofit/afcjk.c (af_cjk_get_standard_widths), src/autofit/aflatin.c (af_latin_get_standard_widths): Use `FT_CALLBACK_DEF`. * src/cff/cffparse.c (cff_parser_run): Initialize and fix allocation of `q`.

It is equivalent to `ftc_gnode_compare` and becomes completely meaningless with fixed signatures. Update all callers. * src/cache/ftcsbits.c, src/cache/ftcsbits.h (FTC_SNode_Compare): Remove redundant function.

Werner Lemberg 8fe50c2a 2023-04-27T23:06:51 [truetype] Fix style name handling for variation fonts. * include/freetype/internal/tttypes.h (TT_FaceRec): New field `non_var_style_name`. * src/sfnt/sfobjs.c (sfnt_load_face): Initialize `non_var_style_name`. (sfnt_done_face): Free `non_var_style_name`. * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Restore non-VF style name if switching back to non-VF mode.
Werner Lemberg c8a24209 2023-04-27T11:40:46 [truetype] Fix PostScript name handling for variation fonts. A variation font's PostScript name of a named instance is usually different from the PostScript name of an unnamed instance. However, if a change between a named instance and an unnamed instance with exactly the same design axis values happened, it was possible that the PostScript name wasn't correctly updated. This commit reorganizes the code to handle this issue within the top-level API functions, using a new service to trigger recomputation of the PostScript name. * include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New typedef. (FT_Service_MultiMasters): New field `construct_ps_name`. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Call `mm->construct_ps_name` to handle `postscript_name`. (FT_Set_Named_Instance): Call `mm->construct_ps_name` to handle `postscript_name`. Use shortcut. * src/cff/cffdrivr.c (cff_construct_ps_name): New function. (cff_service_multi_masters): Updated. * src/truetype/ttgxvar.c (tt_set_mm_blend): Don't handle `postscript_name`. (TT_Set_MM_Blend): Simplify. (TT_Set_Named_Instance): Return -1 if axis values haven't changed. Don't set `face_index`.

Werner Lemberg 6713b1e4 2023-04-26T12:03:04 [truetype] Fix deactivation of variation font handling. According to the documentation, the functions `FT_Set_Named_Instance`, `FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and `FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag. (The same is true for `FT_Set_MM_WeightVector` but this information was accidentally omitted from the documentation.) However, if a call of these functions didn't change the axis values this could fail because internal shortcuts exited too early. This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the top-level API functions, also taking care of the issue at hand. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design, TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector, T1_Set_MM_Design): Ditto. * src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of low-level functions. * src/truetype/ttobjs.c (tt_face_init): Ditto.

suzuki toshiya be15811c 2023-05-03T01:31:37 [t1cid] Improve cid_get_cid_from_glyph_index(). Update cid_get_cid_from_glyph_index() to return an error and CID=0 in the case that the specified glyph index points to an invalid entry. cidgload.h (cid_compute_fd_and_offsets): Declare new helper function to set the fd_select and 2 offsets to access the glyph description data. cidgload.c (cid_compute_fd_and_offsets): Move the part loading fd_select and 2 offsets from cid_load_glyph() to here. If the loaded parameters are broken, return the Invalid_Offset error. This function does not load the glyph data, only fills these parameters. (cid_load_glyph): Use new helper function in above. cidriver.c (cid_get_cid_from_glyph_index): Check whether the requested glyph index points to a valid entry, by calling cid_compute_fd_and_offsets(). If it is valid, fill the cid by the glyph index (=CID). If it is invalid, return an error and fill the cid by 0.
Werner Lemberg 77bbfc59 2023-04-24T09:48:09 API documentation: Re-organize chapters and sections * Split the very long 'Base Interface' section into smaller sections. * Split the 'Core API' chapter into two chapters. * Remove single enumeration values from `@order` fields since they have no effect.

Werner Lemberg 966ff5a5 2023-04-28T15:25:20 * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash. The situation can happen if `FT_New_Face` (or one of its siblings) is called with a negative index to get the number of contained faces, followed immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid use of the FreeType library there is no need for a crash. Fixes #1219.
Werner Lemberg 17a0c5df 2023-04-28T10:40:41 * src/cff/cffdrivr.c (cff_ps_get_font_info): Reject 'CFF2' format.

suzuki toshiya f312b340 2023-04-22T02:11:21 [t1cid] Change the trace messages of the charstrings retrieval errors. The t1cid driver catches 3 types of errors in the charstrings retrieval; A) The invalid FD number, there are 2 subtypes; A-1) FD number is the maximum number fitting to FDBytes. A-2) FD number is greater than num_dicts. B) Declared length is overrunning. C) Declared length is invalid (its end is before its head). Considering that some widely distributed fonts (e.g., "CJKV" book by O'Reilly) have A-1 errors in the unimplemented glyphs, the trace level for A-1 is calmed to level 1. The errors A-2, B, and C would be irregular; their trace levels are kept at level 0, but the updated trace messages include the CID number.
suzuki toshiya 9806414c 2023-04-24T13:36:30 [truetype] Fix `make multi'. * src/truetype/ttgxvar.c: Include freetype/internal/services/svmetric.h for the FT_Service_MetricsVariations type definition.
Ben Wagner 8154d8e2 2023-04-19T13:48:59 [services] FT_Size_Reset_Func to return FT_Error The `MetricsVariations` `FT_Size_Reset_Func` is currently defined to return `void`, but the implementations return `FT_Error`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * include/freetype/internal/services/svmetric.h (FT_Size_Reset_Func): return `FT_Error` instead of `void`.
Ben Wagner c4fe77c3 2023-04-17T11:17:16 [truetype] tt_size_reset_height to take FT_Size The `MetricsVariations` `FT_Size_Reset_Func` is defined to take an `FT_Size`. Because `tt_size_reset_height` is to be used as such a function, it must also take an `FT_Size` instead of a `TT_Size`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * src/truetype/ttobjs.h (tt_size_reset_height): take `FT_Size` * src/truetype/ttobjs.c (tt_size_reset_height): take `FT_Size` and update documentation
Werner Lemberg ea9fca0a 2023-04-13T06:34:32 * src/truetype/ttinterp.c: Remove outdated comments.
Ben Wagner e78e2d29 2023-04-06T11:16:29 [sfnt, truetype] Add `size_reset` to `MetricsVariations`. This is a generalization of commit ``` commit e6699596af5c5d6f0ae0ea06e19df87dce088df8 Author: Werner Lemberg <wl@gnu.org> Date: Thu Feb 2 11:38:04 2017 +0100 [truetype] Fix MVAR post-action handling. ``` It is also possible for plain `CFF ` style fonts to contain an `fvar` and `MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be called with `TT_Size` and never with `CFF_Size`. Allow the "metrics-variations" service to specify the correct function (if any) to reset `FT_Size`s after adjusting metrics. * src/truetype/ttobjs.c (tt_size_reset): Split off some functionality into... (tt_size_reset_height): ... this new function. * src/truetype/ttdriver.c (tt_service_metrics_variations): Add `size_reset`. (tt_size_select, tt_size_request): Updated. * src/truetype/ttobjs.h: Updated. * include/freetype/internal/services/svmetric.h (MetricsVariations): Add `size_reset`. (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec_): Rename `var` to `tt_var` and add `face_var`. * src/cff/cffdrivr.c (cff_service_metrics_variations): Add `size_reset`. (cff_hadvance_adjust, cff_metrics_adjust): Updated. * src/cff/cffobjs.c (cff_face_init): Use `face_var`. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `face_var`. * src/sfnt/ttmtx.c (tt_face_get_metrics): Use `tt_var`. * src/truetype/ttgxvar.c (tt_size_reset_iterator): Renamed to... (ft_size_reset_iterator): ... this new function. Call `size_reset`. (tt_apply_mvar): Pass `size_reset` to `ft_size_reset_iterator`. Fixes #1211
Alexei Podtelezhnikov e77d8ba8 2023-04-10T15:17:17 * src/cff/cffcmap.c (cff_cmap_encoding_char_next): Abbreviate.
Alexei Podtelezhnikov 1a4c18f7 2023-04-10T15:30:43 Align `char_next` return types. This is mostly cosmetic because FT_UInt and FT_UInt32 are likely identical. * src/sfnt/ttcmap.c, src/cff/cffcmap.c, src/psaux/t1cmap.c, src/psnames/psmodule.c, include/freetype/internal/service/svpcsmap.h, src/pfr/pfrcmap.c, src/winfonts/winfnt.c (*_char_next): return FT_UInt.
Alexei Podtelezhnikov d2544433 2023-04-08T23:15:41 [sfnt] Clean up CMAP{4,12,13} handling. This moves the charcode overflow checks upstream and turns some while-loops into the do-while ones to avoid the uninitialized warnings. This should slightly reduce the number of checks and jumps. * src/sfnt/ttcmap.c (tt_cmap{4,12,13}_next, tt_cmap{4.12.13}_char_map_linear): Remove the charcode overflow check. (tt_cmap{4,12,13}_char_map_binary): Ditto and use do-while. (tt_cmap{12,13}_char_next): Add the overflow check.
Alexei Podtelezhnikov b0a4f992 2023-04-02T22:45:48 * src/sfnt/ttpost.c (load_format_25): Do not abort frame reading.
