d0cfb4e1	2022-01-11T10:54:10	Update all copyright notices.
afb4ca01	2022-01-06T12:54:15	[truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742
0da2a115	2021-12-13T11:44:24	[truetype] Upstream the hdmx binary search. * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx widths. * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even though it might never be used by the interpreter. * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches in the hdmx table.
fd03dcc1	2021-12-12T12:29:04	[truetype] Reset the IUP-called flags for each subglyph. This fixes fall-out from 7809007a5b88b15, where the composite accents were no longer hinted. * src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag initialization from here... * src/truetype/ttinterp.c (TT_Run_Context): ... to here.
7add5b2b	2021-12-11T22:54:06	[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances.
a8ef33e3	2021-12-11T22:42:46	[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut.
6c831d65	2021-12-11T22:34:27	[truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded.
7809007a	2021-12-11T22:22:57	[truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here.
a35b081e	2021-12-11T22:12:25	[truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program.
012b00f3	2021-12-07T10:19:06	[truetype] Reduce Infinality footprint again. * src/truetype/ttgload.c (compute_glyph_metrics): Streamline and prioritize the Infinality checks to use `hdmx`.
36a905e1	2021-11-26T09:15:46	* src/truetype/ttpload.c (tt_face_load_hdmx): Added comments.
32f13c11	2021-11-25T22:38:40	[truetype] Quietly reject out-of-spec `hdmx` tables. The `hdmx` table is optional and can be safely rejected without an error if it does not follow specifications. The record size must be equal to the number of glyphs + 2 + 32-bit padding. * src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check the record size and improve tracing.
cff026d4	2021-11-23T16:05:12	[truetype] Partly revert 5b626281. Fixes #1118. * src/truetype/ttpload.c (tt_face_load_hdmx): Do not assume that `record_size` is rounded even though the records are padded.
3cabd142	2021-11-22T19:36:45	Update `CHANGES` files, other minor whitespace and documentation issues.
a11650d7	2021-11-21T07:51:31	* src/truetype/ttinterp.c (Ins_MD): Avoid `FT_ABS`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=38562
e4f7673e	2021-11-13T21:11:00	[truetype] Updates for the forthcoming OpenType 1.9 standard (2/2). * src/truetype/ttgxvar.c (ft_var_load_item_variation_store): s/shortDeltaCount/wordDeltaCount/ (as done in the specification, too). Recognize new format and reject it for now.
93e6b3e8	2021-11-13T14:41:40	[truetype] Updates for the forthcoming OpenType 1.9 standard (1/2). This is in preparation for implementing `DeltaSetIndexMap` format 1, which is used by `COLR` v1 tables, and which allows 32bit indices. https://docs.microsoft.com/en-us/typography/opentype/otspec190/delta/otvarcommonformats_delta.html * src/truetype/ttgxvar.h (GX_DeltaSetIdxMapRec): Change type of `mapCount` to `FT_ULong`. * src/truetype/ttgxvar.c (ft_var_load_delta_set_index_mapping): Add argument for passing the table size; update caller. Implement new format.
c5cd2a3d	2021-11-10T08:46:26	* src/truetype/ttgxvar.c (ft_var_to_normalized): Edge optimization.
bb4e049a	2021-11-04T08:58:13	[truetype] Make trickyness checks depend on TT_USE_BYTECODE_INTERPRETER. Based on a patch from metarutaiga (MR !106). * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag, tt_check_trickyness_family, tt_synth_sfnt_checksum, tt_get_sfnt_checksum, tt_check_trickyness_sfnt_ids, tt_check_trickyness): Put functions into a `TT_USE_BYTECODE_INTERPRETER` block. (tt_face_init): Put trickyness checks into a `TT_USE_BYTECODE_INTERPRETER` block. Fixes #1111.
cb9e7b7a	2021-11-06T22:59:31	[truetype] Avoid some memory zeroing in variations. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas, ft_var_load_avar, ft_var_load_item_variation_store, ft_var_load_gvar): Use FT_QNEW_ARRAY if memory immediately initialized or discarded otherwise.
fc55291b	2021-11-04T11:07:43	[truetype] Fix handling of packed deltas in Variation Fonts. * src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of bytes used to encode the deltas to be higher than the number of encoded values. The specification allows a very compact encoding; for example, a list of 200 zeros can be encoded with just a couple of bytes. We now count the consumed bytes to make sure to not read more than expected.
9ed5332f	2021-11-04T08:56:59	[truetype] Fix CVAR handling of tuples for all points. * src/truetype/ttgxvar (tt_face_vary_cvt): Function `ft_var_readpackedpoints`, when it returns `ALL_POINTS`, also sets `point_count` to value 0. However, the CVAR code was incorrectly expecting that `point_count` would be set to match the length of the CVT table.
23d1d8ad	2021-11-04T08:55:39	* src/truetype/ttgxvar.c: Fix typos in macros that guard CVAR code.
94cb3a2e	2021-10-29T10:31:59	* src/truetype/ttgload.c (load_truetype_glyph): Fix MSVC warning C4312.
8406ae53	2021-10-15T14:16:30	[truetype] Reload context after re-executing `prep`. When a different hinting mode from the current is selected, the `prep` table must be re-executed with the new mode. After this happens the context must be re-loaded in preparation for the glyph program to be run. Fixes #1104. * truetype/ttgload.c (tt_loader_init): Add call to `TT_Load_Context`.
0b92c56c	2021-10-15T19:02:41	[truetype] Minor documentation improvements.
22befeef	2021-10-07T22:41:56	Signedness revisions. This eliminates explicit casting by switching to unsigned fields. The revisions mostly impact the handling of CID fonts. * include/freetype/fttypes.h (FT_Data): Change to unsigned `length`. * include/freetype/t1tables.h (CID_FaceDictRec): Ditto for `sd_bytes`. (CID_FaceInfoRec): Ditto for `gd_bytes` and `gd_bytes`. * include/freetype/internal/tttypes.h (TT_LoaderRec): Ditto for `byte_len`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.h (cid_get_offset): Update argument. * src/cid/cidload.c (cid_get_offset, cid_read_subrs, cid_face_open): Updated. * src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): Updated. * src/psaux/psft.c (cf2_getT1SeacComponent): Updated. * src/truetype/ttgload.c (TT_Process_Composite_Glyph, load_truetype_glyph): Updated.

073ff2d7	2021-09-13T00:04:45	[truetype] Clean up `exec` initialization. * src/truetype/ttinterp.c (Init_Context): Absorbed into... (TT_New_Context): ... this function.
fab94f9f	2021-09-12T23:30:07	[truetype] Avoid some memory zeroing. * src/truetype/ttgload.c (load_truetype_glyph): Use Q-macro. * src/truetype/ttinterp.c (Update_Max): Ditto. * src/truetype/ttpload.c (src/truetype/ttpload.c): Ditto.
5b626281	2021-09-10T10:19:07	[truetype] Tweak `hdmx` checking. Fixes #1096. * src/truetype/ttpload.c (tt_face_load_hdmx): Account for padding.
e942a310	2021-09-09T22:17:46	[truetype] Tweak `loca` clamping. Fixes #1095. * src/truetype/ttpload.c (tt_face_load_loca): Fix up clamping. * include/freetype/internal/tttypes.h (TT_Face): Correct docs.
d1c20005	2021-08-28T07:29:05	[truetype] Fix compilation if !TT_CONFIG_OPTION_BYTECODE_INTERPRETER. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): Compile function conditionally. (tt_face_vary_cvt) [!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Add code. Fixes #1091.
50318357	2021-08-25T00:31:26	[truetype] Fix for the family name shorter than 8 characters. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): If the family name to be checked is shorter than 8 characters, do not check its syntax.
c4fc0e69	2021-08-24T12:29:47	[truetype] Simplify `trick_names'. * src/truetype/ttobjs.c (tt_check_trickyness_family): For the case that the beginning part of a long tricky family name is already registered as another tricky family name, no need to double-check the longer one. Such long tricky family names are removed from the `trick_names'.
992382ba	2021-08-24T12:11:46	[truetype] Add 2 tricky font names. Additional fix for the issue #1087. * src/truetype/ttobjs.c (tt_check_trickyness_family): Add 2 tricky font names reported in #1087.
2b3ccd6e	2021-08-24T11:43:11	[truetype] New function to skip the randomization tag. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): New function to skip the randomization tag in the names of the fonts embedded in a PDF. It is used by tt_check_trickyness_family(), to keep from mistaking "DLC" in the randomization tag as a tricky font name. See discussion in: https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html For technical detail about the randomization tag, please find PDF Reference 5.5.3 "Font Subsets". Thanks to Justyna Wawrzynska for pointing out the issue caused by the randomization tag.
1c23982d	2021-08-24T10:25:22	[truetype] Add checksums for 2 tricky fonts. Thanks to Ting717 for providing sample PDF. Fixes #1087. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Add checksums for 2 tricky fonts `DFHei-Bd-WIN-HK-BF' and `DFMing-Md-WIN-HK-BF'.
78f2bd0b	2021-08-22T22:32:07	Whitespace formatting.
f11f3ed1	2021-08-18T06:54:34	[base] Fix ppem size overflow. Fixes #1086. * src/base/ftobjs.c (FT_Request_Metrics): Add return value. Check whether ppem values fit into unsigned short values. (FT_Request_Size): Updated. * include/freetype/internal/ftobjs.h: Updated. * src/cff/cffobjs.c (cff_size_request), src/cid/cidobjs.c (cid_size_request), src/truetype/ttdriver.c (tt_size_request), src/type1/t1objs.c (T1_Size_Request): Updated.
d3dc2da9	2021-06-30T18:22:29	* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue.
b460a506	2021-06-19T07:03:40	[truetype] Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35312 * src/truetype/ttinterp.c (Ins_JMPR): Use `ADD_LONG`.
9bfecfd2	2021-06-09T23:34:04	* src/truetype/ttinterp.c (TT_RunIns): Optimize tracing.
a50c39aa	2021-05-29T09:50:29	Fix compilation errors and (some) warnings for clang++. * src/autofit/afmodule.c (AF_GlyphHintsRec): Make it static. * src/cache/ftcache.c (FTC_Cache_NewNode), src/cache/ftcsbits.c (ftc_snode_compare): Remove semicolon. * src/cff/cffparse.c (cff_parser_run): Add `break` statement. * src/cid/cidload.c (cid_hex_to_binary): Add cast. * src/sdf/ftbsdf.c (CHECK_NEIGHBOR): Use `do {} while(0)` loop. (bsdf_init_distance_map, finalize_sdf, bsdf_raster_render): Add casts. * src/sdf/ftsdf.c (sdf_generate_bounding_box, sdf_generate_with_overlaps): Ditto. * src/sdf/ftsdfcommon.h (square_root): Ditto. * src/sdf/ftsdfrend.c (sdf_property_get, ft_sdf_render, ft_bsdf_render): Ditto. * src/sfnt/ttcolr.c (find_base_glyph_record, find_base_glyph_v1_record): Fix variable signedness. (read_color_line): Add cast. (read_paint): Add casts. Fix signedness issue. (tt_face_get_colorline_stops) Fix signedness issues. * src/sfnt/ttpost.c (load_format_20): Add casts. * src/truetype/ttsubpix.c (TWEAK_RULES, TWEAK_RULES_EXCEPTIONS): Remove final semicolons.
56ae9430	2021-05-01T09:14:04	[truetype] Avoid some memory zeroing. * src/truetype/ttinterp.c (Init_Context): Tweak allocation macro. * src/truetype/ttpload.c (tt_face_load_cvt): Ditto.
52f2a008	2021-04-01T09:33:47	Update TT_New_Context documentation In commit 531d463aed365b [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. the `TT_ExecContext` was moved from being on the driver to being on the size to make it easier to use FreeType in a multi-threaded environment. However, the documentation for `TT_New_Context` was not updated and still reflects the old behavior and parameter list. This change updates `TT_New_Context` documentation to reflect the current parameters and usage.
369d8be9	2021-03-31T22:31:44	[truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`. (Write_CVT, Write_CVT_Stretched, Move_CVT, Move_CVT_Stretched): Use it. (Ins_WS): Handle `exc->glyfStorage`. (Ins_FDEF, Ins_IDEF): Updated. (TT_RunIns): Updated. (TT_Done_Context): Free 'glyf' CVT working and storage area. (TT_Load_Context): Fix/add casts. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Fix cast.
2149b51f	2021-03-13T19:08:09	Handle various VC++ compiler warnings. Fixes #1039. * src/base/ftstroke.c (ft_stroker_inside, ft_stroker_outside): Initialize `sigma`. * src/sdf/ftsdf.c (sdf_generate_with_overlaps): Exit immediately if function arguments are invalid. * src/sdf/ftsdfrend.c (sdf_property_set) <"overlaps">: Fix cast. * src/sfnt/sfwoff2.c (woff2_decompress) [!FT_CONFIG_OPTION_USE_BROTLI]: Use `FT_UNUSED`. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Initialize `fvar_head`.
d924a66a	2021-02-04T07:44:06	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested). This is a continuation of a similar patch from 2020-12-02, which missed some locations.
b6e8a712	2021-01-17T07:18:48	Update all copyright notices.
c6ff2556	2020-12-26T10:50:21	[sdf] Use 'counter-clockwise', not 'anti-clockwise'. We prefer US nomenclature. * src/sdf/ftsdf.c (SDF_Contour_Orientation): s/SDF_ORIENTATION-ACW/SDF_ORIENTATION_CCW/. Update all users.
f6be9276	2020-12-16T06:03:10	[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but not for the purpose of imposing custom metrics.
272ae5ee	2020-12-07T10:29:24	* src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`.
a6adb256	2020-12-02T14:15:07	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).
6d9e6b21	2020-08-28T09:56:38	* src/*: Fix `-Wformat` warnings.
1286f58c	2020-11-20T14:54:35	Downgrade property tracing.
804e625d	2020-10-28T13:34:52	[truetype] Minor update to forthcoming OpenType 1.8.4 standard. * src/truetype/ttgxvar.c (ft_var_load_item_variation_store): Limit size of `regionCount`.
600d59e3	2020-09-02T15:48:03	[truetype] Reduce Infinality footprint (cont'd). * src/truetype/ttinterp.c (Ins_DELTAP): Shrink variable scope. (Ins_SHPIX, Ins_MIRP): Revise if-logic.
51a5e338	2020-09-02T00:02:28	[truetype] Reduce Infinality footprint. * src/truetype/ttinterp.c (Ins_SHPIX, Ins_MSIRP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Shrink variable scopes and consolidate ifdefs.
e6c7e4b4	2020-09-01T21:49:52	[truetype] Refactor compensation color. * src/truetype/ttinterp.h (TT_Round_Func): Change the last argument. * src/truetype/ttinterp.c (Ins_ROUND, Ins_NROUND, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Move compensation retrieval from here... (Round_): ... to here. src/truetype/ttobjs.c (tt_size_init_bytecode): Reserve zero compensation at color index 3.
cdc009c2	2020-08-22T13:30:11	* src/truetype/ttgload.c (TT_Get_VMetrics): Add tracing message.
f9f6adb6	2020-08-05T08:24:15	[truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND. For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set FT_OUTLINE_OVERLAP to render them with direct oversampling, which mitigates artifacts (see 3bb512bc9f62). * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Redefine to rhyme with OVERLAP_SIMPLE. * src/base/ftgloadr.c (FT_GlyphLoader_Rewind): Reset outline flags. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Retain OVERLAP_SIMPLE. (load_truetype_glyph): Retain OVERLAP_COMPOUND.

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.
4eee1340	2020-05-18T09:16:12	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.

11975fe9	2020-02-29T20:18:00	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.

Up to now, only the unscaled CVT values were varied; in other words, the `CVAR' data was never used for bytecode hinting. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary function. (tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
37580053	2019-05-16T12:15:54	[truetype] Use 26.6 format for storing unscaled CVT values. If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro.

[truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742

[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances.

2021-12-11T22:42:46

[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut.

(tt_loader_init): ... to here, before the glyph is loaded.

2021-12-11T22:22:57

[truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here.

[truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program.

[truetype] Quietly reject out-of-spec `hdmx` tables. The `hdmx` table is optional and can be safely rejected without an error if it does not follow specifications. The record size must be equal to the number of glyphs + 2 + 32-bit padding. * src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check the record size and improve tracing.

[truetype] Fix handling of packed deltas in Variation Fonts. * src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of bytes used to encode the deltas to be higher than the number of encoded values. The specification allows a very compact encoding; for example, a list of 200 zeros can be encoded with just a couple of bytes. We now count the consumed bytes to make sure to not read more than expected.

[truetype] New function to skip the randomization tag. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): New function to skip the randomization tag in the names of the fonts embedded in a PDF. It is used by tt_check_trickyness_family(), to keep from mistaking "DLC" in the randomization tag as a tricky font name. See discussion in: https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html For technical detail about the randomization tag, please find PDF Reference 5.5.3 "Font Subsets". Thanks to Justyna Wawrzynska for pointing out the issue caused by the randomization tag.

In addition, `TT_Set_MM_Blend` has a similar possible issue.

Update TT_New_Context documentation In commit 531d463aed365b [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. the `TT_ExecContext` was moved from being on the driver to being on the size to make it easier to use FreeType in a multi-threaded environment. However, the documentation for `TT_New_Context` was not updated and still reflects the old behavior and parameter list. This change updates `TT_New_Context` documentation to reflect the current parameters and usage.

[truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`.

[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but *not* for the purpose of imposing custom metrics.
