73318c86 | 2025-01-08 15:45:32 | [cff] Remove size/slot checks. After the previous commit, cff_glyph_load is no longer called without first checking for valid size and glyph objects in FT_Glyph_Load and these checks can be removed downstream. * src/cff/cffdrivr.c (cff_glyph_load): Remove `size` and `glyph` checks. * src/cff/cffgload.c (cff_slot_load): Ditto. | |
|
c7a255b4 | 2025-01-07 19:52:29 | * src/cff/cffdrivr.c (cff_get_advances): Do only fast advances. Otherwise, let TT_Get_Advances fall back on cff_load_glyph to do slow advances. This avoids unchecked access to cff_load_glyph and this is how tt_get_advances is implemented. | |
|
5245fd69 | 2025-01-03 21:26:10 | Delay FT_GLYPH_FORMAT_OUTLINE assignmets. This assignmets used to be done prematurely before errors were checked and outlines were actually loaded. Delaying the assignment provides certain protection against careless usage of malformed input that should now remain FT_GLYPH_FORMAT_NONE. * src/cff/cffgload.c (cff_slot_load): Ditto. * src/cid/cidgload.c (cid_slot_load_glyph): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Ditto. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. | |
|
64f8b7fb | 2025-01-02 18:22:24 | Remove superfluous outline zeroing. This is already done by `ft_glyphslot_clear`. * src/cff/cffgload.c (cff_slot_load): Do not zero outline fields. * src/cid/cidgload.c (cid_slot_load_glyph: Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Ditto. * src/truetype/ttgload.c (load_sbit_image): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. | |

59320b2d | 2024-12-04 16:55:10 | [cff] Fix leak of cmap data When `sfnt->load_face` succeeds it has already loaded any (optional) cmap data. As a result, a subsequent call to `sfnt->load_cmap` will overwrite the cmap data pointer with a new copy of the data but not free the old, leading to a leak. This is a fix for "* src/cff/cffobjs.c (cff_face_init): Better handling of Type0 fonts.". This still allows the cmap to be missing but avoids the leak by only calling `sfnt->load_cmap` when there is no `head` table (the font data is not being loaded as OpenType/CFF). * src/cff/cffobjs.c (cff_face_init): Fix leak Fixes: #1306 | |
 |
3f3e3de3 | 2024-11-06 06:28:41 | * src/cff/cffobjs.c (cff_face_init): Better handling of Type0 fonts. This issue relates to the PDF specification and its usage of CFF-based embedded Type0 fonts. For Type0 fonts containing CID-keyed descendant CFF-based fonts, the glyph index is the CID present in the content stream. As a result, there is no requirement for a 'cmap' table to be present in the font since the glyph indices are derived directly from the CIDs. FreeType throws an error when it doesn’t find a 'cmap' table for such an Open Type font containing CFF outlines. This commit relaxes this requirement for a 'cmap' table for such fonts. | |

5f131cfd | 2024-05-21 16:24:43 | [cff, truetype] Validate variation axes immediately. Instead of validating variation axes in every access, OpenType specs suggest that peak = 0 be used to tag invalid ranges. This implements just that once during loading. * src/cff/cffload.c (cff_blend_build_vector): Move the range checks... (cff_vstore_load): ... here. * src/truetype/ttgxvar.c (tt_var_get_item_delta): Ditto... (tt_var_load_item_variation_store): ... ditto. | |
|
99be2b31 | 2024-05-21 18:26:09 | [cff, truetype] Rearrange variation range checks. This should achieve quicker results for common cases. * src/cff/cffload.c (cff_blend_build_vector): Rearrange conditionals. * src/truetype/ttgxvar.c (tt_var_get_item_delta): Ditto. | |
|
4ccdc9f9 | 2024-05-20 18:53:57 | [cff] Optimize the blend vector computations. * src/cff/cffload.c (cff_blend_build_vector): Use FT_MulDiv and skip multiplying by 1. | |
 |
2a790a9f | 2024-02-28 17:45:19 | [cff, truetype] Always set up default variable instance. For default variable instances `cff_face_init` did not set the blend. This mostly worked as later use of the unset blend produced the default variation. However, if a user called `TT_Get_MM_Var` the blend would be partially set up, but not fully. In particular the number of axes, the axis definitions, and the instance locations would be set up, but not the current instance location (`coords` and `normalizedcoords`). This could lead to the default instances of CFF2 fonts erroring on any use of `blend`. Ensure the default variable instance is fully set up by always calling `FT_Set_Named_Instance` on a variable face. * src/cff/cffobjs.c (cff_face_init): Call `FT_Set_Named_Instance` on default instances. * src/truetype/ttobjs.c (tt_face_init): Ditto. Fixes #1268. | |

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_make_private_dict): Use it. * src/cff/cffparse.h (cff_kind_delta_fixed): New enum value. * src/cff/cffparse.c (do_fixed): Updated. (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. | |

3c92e7bf | 2023-07-14 18:58:55 | [cff] Fix compiler warning. * src/cff/cffparse.c, src/cff/cffparse.h: Make `cff_parse_fixed` a local function. | |
|
26a7f047 | 2023-07-11 01:40:25 | [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. | |
|
2fb8eda5 | 2023-06-01 19:38:36 | */*: 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. | |
|
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. | |
|
e02a40a4 | 2023-05-08 20:12:26 | * 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 | |
|
5edd6d52 | 2023-05-08 07:22:59 | 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`. | |

c0414119 | 2023-05-06 18:57:42 | * src/cff/*: Clean up interface. Ensure that all driver functions use the signature of the service or driver. This avoids pointer mismatches, which are technically undefined behaviour. Recent compilers are more picky in catching them as part of Control Flow Integrity tests. | |

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. (TT_Set_Named_Instance): Return -1 if axis values haven't changed. Don't set `face_index`. (tt_construct_ps_name): New function. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. * src/type1/t1driver.c (t1_service_multi_masters): Updated. * src/type1/t1load.c (T1_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. | |

966ff5a5 | 2023-04-28 15:25:20 | * 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. | |

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`.

4f0a55d1 | 2023-03-19 10:13:52 | [cff] Rework the stream limit checks. The old stream limit checks, before 6986ddac1ece, were good but pointless for the crafted t2_strings. Checking limits there is not necessary as they are created to hold all data. By using two conditions, we can detect the actual crossing of the stream boundary as appropriate for the stream pointer only. The t2_strings parsing will not be triggering these checks. * src/cff/cffparse.c (cff_parser_within_limits): Removed. (cff_parse_real, cff_parse_integer): Redesign the stream limit check.

a4434747 | 2020-06-20 05:31:34 | [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. | |
|
f594ffdc | 2020-06-19 18:55:49 | [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. | |
|
8ed5a247 | 2020-06-19 10:35:57 | [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'. | |
|
575b78d9 | 2020-06-18 15:12:03 | [cff] Fix memory leak (#58610). * src/cff/cffobjs.c (cff_size_init): When the call to `funcs->create' fails, make sure to free `internal'. | |

|
16586859 | 2020-06-13 21:15:45 | Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. | |
 |
e1339133 | 2020-06-08 13:31:55 | 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 | 2020-05-18 09:16:12 | 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. | |

 |
1e9229f0 | 2019-10-09 15:37:19 | [cff] Fix FT_FACE_FLAG_GLYPH_NAMES for CFF2 based fonts (#57023). * src/cff/cffobjs.c (cff_face_init): Don't set FT_FACE_FLAG_GLYPH_NAMES for CFF2 based fonts. | |

6986ddac | 2019-03-31 11:08:49 | [cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine. Bounds checks have never been updated, however, leading to pointless comparisons of pointers in some cases. This commit presents a solution for bounds checks in the CFF module with an extended logic for the "old" engine while staying as concise as possible for the "new" one. * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and the additional field `t2_strings' within `CFF_ParserRec'. * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary checks into this new function and update the rest of `cffparse.c' to use it.
