8f286c86 | 2024-01-19 16:42:48 | Add support for kerning from 'GPOS' tables. This commit adds support for kerning from 'GPOS' tables, while maintaining support for basic 'kern' tables. `FT_HAS_KERNING` will be true for a font with either available and `FT_Get_Kerning` will still use the basic 'kern' table data if avilable, otherwise check the GPOS 'kern' feature. This feature is disabled by default; it can be enabled with the `TT_CONFIG_OPTION_GPOS_KERNING` flag. Only basic kerning (pair positioning with just an x advance) is supported from the GPOS layout features; support for that was added to make the existing `FT_Get_Kerning` API more consistently functional. FreeType does not intend to extend itself to further GPOS functionality though; a higher-level library like HarfBuzz can be used instead for that. * include/freetype/config/ftoption.h, include/devel/ftoption.h (TT_CONFIG_OPTION_GPOS_KERNING): New configuration option. * include/freetype/internal/fttrace.h: Add `ttgpos` trace handler. * include/freetype/internal/sfnt.h (SFNT_Interface): Add `load_gpos` and `get_gpos_kerning` fields. (FT_DEFINE_SFNT_INTERFACE): Updated. * include/freetype/internal/tttypes.h: Include `fttypes.h`. (TT_FaceRec) [TT_CONFIG_OPTION_GPOS_KERNING]: Add `gpos_table` and `gpos_kerning_available` fields. * src/sfnt/ttgpos.c, src/sfnt/ttgpos.h: New files. * src/sfnt/sfdriver.c [TT_CONFIG_OPTION_GPOS_KERNING]: Include `ttgpos.h`. (sfnt_interface): Updated. * src/sfnt/sfnt.c: Include `ttgpos.c`. * src/sfnt/sfobjs.c [TT_CONFIG_OPTION_GPOS_KERNING]: Include `ttgpos.h`. (sfnt_load_face) [TT_CONFIG_OPTION_GPOS_KERNING]: Load and free GPOS kerning data; check GPOS kerning availability. * src/truetype/ttdriver.c (tt_get_kerning): Use GPOS kerning if there's no 'kern' table. | |

8eab5110 | 2023-12-14 06:59:05 | [CFF] Extract `BlueValues` as `Fixed` rather than `Int`. This is a follow-up to commit 26a7f047, [cff] Make blend operator work with floats in private dicts. which addressed the 'party baseline' bug. However, the reporting user indicated that the default location and some other points in design space rendered OK, but other points in design space still had problems. The most obvious issue being that the x-heights of lower-case letters did not align; see https://github.com/adobe-fonts/source-serif/issues/121#issuecomment-1773794136 After some analysis we determined that this was due to an interaction between `BlueValue` rounding and the zone-based algorithm. In short, for a point to be considered in a zone it must fall within the bounds of the zone. (There is a slop factor in some cases, but only a very small one.) In the Adobe-contributed side of the code, point values are not integer-rounded, instead they're kept as (some form of) fixed. Rounding just the `BlueValues` means that points that need to be considered within a zone will fall outside of it at some points in design space. The majority of this patch changes the storage and parsing of `BlueValues` to keep them as `FT_Fixed`. No significant code changes were needed because the values are converted to `Fixed` anyway when stored in `CF_BlueRec`. No attempt was made to address problems in the older pshinter code beyond converting the values from `FT_Fixed` to `FT_Short` when copying the private dictionary. (However, as the point values are also rounded in that code, the problem is much less likely to occur, although inconsistency between rounding and truncation could cause an analogous problem.) * include/freetype/internal/cfftypes.h (CFF_PrivateRec): Use `FT_Fixed` for `blue_values`, `other_blues`, `family_blues`, and `family_other_blues`. * src/cff/cffload.c (cff_blend_doBlend): Updated. * src/cff/cffobjs.c (CFF_fixedToInt): New macro.

(CFF_FIELD_DELTA, CFF_FIELD_DELTA_FIXED, CFF_DELTA_KIND): New set of macros, replacing `CFF_FIELD_DELTA`. (cff_parser_run): Updated to handle fixed-float deltas. * src/cff/cfftoken.h: Updated to use `CFF_FIELD_DELTA_FIXED` for blue values. * src/psaux/psblues.c (cf2_blueToFixed): Removed, no longer needed. (cf2_blues_init): Updated. * src/pxaux/psft.c, src/pxaux/psft.h (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated signatures. * src/psaux/psobjs.c (t1_make_subfont): Updated. | |

4e1c0e8f | 2023-06-05 11:53:34 | 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. | |
|
7bed7a02 | 2023-06-01 21:05:32 | 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. | |
|
80a507a6 | 2023-05-23 13:13:56 | 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`. | |

115e9275 | 2023-05-19 12:11:45 | [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. | |
|
416d4c25 | 2023-05-15 15:44:36 | 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. | |

c8a24209 | 2023-04-27 11:40:46 | [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.

6713b1e4 | 2023-04-26 12:03:04 | [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. | |

8154d8e2 | 2023-04-19 13:48:59 | [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`. | |

e78e2d29 | 2023-04-06 11:16:29 | [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 | |
|
1a4c18f7 | 2023-04-10 15:30:43 | 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. | |

d5d048bb | 2022-07-03 20:26:31 | doc: Clarify description of `FT_Stream_IoFunc`. The existing documentation comments on `FT_Stream_IoFunc` hinted at the dual seek/read behavior required for custom stream implementations to work, but it didn't explicitly explain it. Without looking at the internals of FreeType, it was easy for someone to assume their implementation should handle both seek and read operations all the time. If this is done, you get a variety of errors, but mostly just `Unknown_File_Format` (error code 0x02). | |

f7daf9d2 | 2022-06-17 12:37:02 | [stream] Fix reading s32 when long is s64 `FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return negative values when `long` is more than 32 bits. `FT_Stream_ReadULong` would read four bytes into the LSB of an `FT_ULong` and return that. Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is more than 32 bits the cast to `FT_Long` never resulted in a negative value. Fix this by modifying `FT_Stream_Read*` to return a type of the same size as the bytes it is reading and changing the `FT_READ_*` and `FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*` but with the correctly signed type (instead of casting to what is assumed to be the type of `var` which will happen automatically anyway). There exist a few cases like with the `OFF3` variants where there isn't generally a type with the correct size. `FT_PEEK_OFF3` works around this loading the bytes into the three most significant bits and then doing a signed shift down. `FT_NEXT_OFF3` also already worked correctly by casting this signed value to another signed type. `FT_Stream_GetUOffset` works correctly but one must be careful not to attempt to cast the returned value to a signed type. Fortunately there is only `FT_GET_UOFF3` and no `FT_GET_OFF3`. All of these cases are handled correctly when reading values through `FT_Stream_ReadFields` since it generically computes the signed value through an `FT_Int32`. This change is essentially doing the same for these macros. * include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*): Update macros and return types to use fixed size types for fixed size values. * src/base/ftstream.c (FT_StreamGet*, FT_StreamRead*): Dito.
