| 4797b2ff | 2022-08-26 12:08:34 | [sfnt] Avoid undefined shifts in `COLR` v1 color line retrieval * src/sfnt/ttcolr.c (tt_face_get_colorline_stops): Disambiguate shift behavior by using multiplication using macros from ftcalc.h.

| 284956b5 | 2022-07-26 12:23:15 | [pfr] Fortify the kerning code. Any array index must be strictly less then the array size. Therefore, we must reject indexes that are equal to the array size. Alternatively, we should move the bounds check before the index decrement but that would be confusing. In addition, it is ok to decrement zero (.notdef) and get UINT_MAX, which is then automatically rejected in the bounds check. * src/pfr/pfrobjs.c (pfr_face_get_kerning): Fix the bounds checking. | ||
| 182295cb | 2022-07-26 16:08:00 | [pfr] Add some safety guards. * src/pfr/pfrload.c (pfr_phy_font_load): Check resolutions and number of characters. Fixes #1174. | ||
| 1f005c09 | 2022-07-26 16:05:35 | * src/pfr/*.c: Trivial improvements and formatting. | ||
| 0417e54b | 2022-07-22 16:22:19 | [base] Build outlines in amortized constant time. When resizing the loader's points and contours, resize them to at least 1.5 times their current size. The code currently only reserves as much space as is currently required, leading to O(n^2) runtime when adding points one at a time. This change does not attempt to ever shrink the loader's point and contour storage since this was not attempted previously either. The 1.5 multiple was chosen as a trade-off between potentially unused space and the runtime. * src/base/ftgloader.c (FT_GlyphLoader_CheckPoints): Implement it. Fixes #1173. | ||
| 275b116b | 2022-07-05 15:16:31 | [sfnt] Support variable 'COLR' v1 `PaintVarSkew*`. * src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration values `FT_COLR_PAINTFORMAT_INTERNAL_VAR_SKEW`, `FT_COLR_PAINTFORMAT_INTERNAL_SKEW_CENTER`, and `FT_COLR_PAINTFORMAT_INTERNAL_VAR_SKEW_CENTER`.

| 8ec531c2 | 2022-07-05 14:47:57 | [sfnt] Support for 'COLR' v1 variable transforms. * src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration value `FT_COLR_PAINTFORMAT_INTERNAL_VAR_TRANSFORM`. (read_paint): Handle new enumeration value. | ||
| 9c4ad2a9 | 2022-07-05 14:43:10 | [sfnt] Deltas for 'COLR' v1 gradient coordinates. * src/sfnt/ttcolr.c (read_paint) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Read and apply deltas to radial, linear, and sweep gradient coordinates such as 'p0', 'p1', 'p2', 'center', 'radii', and 'angles'. | ||

(read_color_line): New parameter `read_variable`; update callers. (read_paint): Handle new enumerations. | ||
| 7c151abb | 2022-07-04 12:44:06 | [sfnt] Apply variation deltas to `PaintVarSolid`. * src/sfnt/ttcolr.c (FT_PaintFormat_Internal_): New enumeration `FT_COLR_PAINTFORMAT_INTERNAL_VAR_SOLID`. (get_deltas_for_var_index_base) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to retrieve an array of delta values, which will be used for most of 'COLR' v1 variation formats (in follow-up commits). (read_paint): Add `face` parameter; update caller. Handle `FT_COLR_PAINTFORMAT_INTERNAL_VAR_SOLID`. | ||
| 8a9192f6 | 2022-07-07 13:02:10 | [sfnt] Check safety of cast to `TT_Driver` before accessing member. * src/sfnt/ttcolr.c (VARIABLE_COLRV1_ENABLED): Access `enable_variable_colrv1` only if driver class matches. | ||

(tt_face_load_colr, tt_face_free_colr) [VARIABLE_COLRV1_ENABLED]: Load and free variation store data using the functions from the Multiple Masters service. | ||
| 1a242558 | 2022-06-30 09:25:14 | [base] Improve error handling in `FT_GlyphLoader_CheckPoints`. If `FT_GlyphLoader_CreateExtra` returns an error (and a couple of other places), `FT_GlyphLoader_CheckPoints` would propagate the error immediately, rather than cleaning up the partially set up `FT_GlyphLoader`. As a consequence, a subsequent attempt to create a glyph could result in a crash. * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Ensure all the error conditions exits are consistent, eventually calling `FT_GlyphLoader_Reset`. | ||
| bec4ef41 | 2022-07-01 12:04:28 | [base] Round values in `FT_MulAdd_Fix`. This avoids regressing Blink layout tests and makes `FT_MulAdd_Fix` delta retrieval implementation consistent with the previous implementation, which used `FT_fixedToInt` and included rounding. * src/base/ftcalc.c (FT_MulAdd_Fix): Implement it. Also fix remaining `temp` initialization compilation issue. Fixes #1169. | ||
| de27955c | 2022-07-01 06:33:50 | Minor formatting. | ||
| 0607e0e9 | 2022-06-30 10:55:50 | Fix initialisation of temp variable in new FT_MulAddFix src/truetype/ttgxvar.c (FT_MulAddFix): Initialise `temp`. | ||

| 15fef219 | 2022-06-29 11:48:10 | New function `FT_MulAddFix` to compute the sum of fixed-point products. This function, based on the code of `FT_MulFix`, uses 64-bit precision internally for intermediate computations. * include/freetype/internal/ftcalc.h, base/ftcalc.c (FT_MulAddFix): Implement it. | ||
| 117df36b | 2022-06-22 09:33:20 | [sfnt] Upgrade stop_offset to FT_Fixed from FT_F2Dot14 | ||

| 47103b2f | 2022-06-18 23:09:17 | [truetype] Clean up phantom point accounting. This formalizes that the phantom points appended in the outline do not increase its point count, nor are they tagged or included in any additional contours. Only their coordinates are stored. They are counted in the glyph zone, however. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Infer `n_points` from the outline size plus four phantom points. * src/truetype/ttgxvar.h (TT_Vary_Apply_Glyph_Deltas): Remove this argument. * src/truetype/ttgload.c (tt_prepare_zone): Add phantom four. (TT_Process_Simple_Glyph, load_truetype_glyph): Update all callers. | ||
| 705f4161 | 2022-06-18 23:02:26 | [truetype/GX] Clean up phantom point adjustment. This moves phantom point and advance variation adjustment next to calculations. The logic stays the same, HVAR and VVAR take priority. * src/truetype/ttgload.c (load_truetype_glyph): Move it from here... * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): ... to here and check for HVAR and VVAR presence outside the main loop. | ||
| 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.

| 9c706dcc | 2022-06-16 16:11:51 | [truetype/GX] Clean up advance adjustment (Brrr). * src/truetype/ttgload.c (load_truetype_glyph): Remove remaining code. | ||
| 90795210 | 2022-06-15 16:07:22 | [type1] Directly search for eexec in private dict This code originally just searched for `eexec`. This was later modified to check that the `eexec` found is valid (not in a string or comment). This was done by searching for `eexec` as before and then, for each `eexec` found, searching from the beginning using the correct parsing to see if the `eexec` was still found. If the private dictionary is large and contains many copies of `eexec` which are not valid, the initial part of the private dictionary is scanned once for each, potentially leading to n^2 parsing time. Instead of finding an initial `eexec` and then re-parsing to discover if it is valid, drop the initial search for `eexec` and just parse to find a valid `eexec`. This is strictly faster since the validation must happen anyway and avoids restarting from the beginning each time an `eexec` is found in the data. * src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1328883 | ||

| 8bb7722a | 2022-06-13 15:09:36 | [gzip] Handle inflate returning Z_NEED_DICT When `inflate` returns `Z_NEED_DICT` this is currently not reported as an error and callers may assume that the decompression succeeded when it did not. In particular, a compressed table in a woff file may not actually be decompressed and written as expected, leaving the backing memory for the expanded table uninitialized. * src/gzlip/ftgzip.c (FT_Gzip_Uncompress): treat `Z_NEED_DICT` as indicating invalid data since there is no means to provide a dictionary.

| 360e2507 | 2022-03-04 16:58:50 | [sdf] Fix corner checks and improve performance. * src/sdf/ftsdf.c (sdf_generate_bounding_box): Always check for a corner if two distances (for different curves) are very close. (sdf_conic_to): Check whether the conic curve can be treated as a line (which happens if the control point coincides with any end point). | ||
| 2600ef63 | 2022-03-04 16:53:27 | [sdf] Implement deviation-based splitting for Bezier curves. * src/sdf/ftsdf.c (split_sdf_cubic, split_sdf_shape): Add checks to figure out the deviation of Bezier curves and stop splitting if the curve is flat enough. * src/sdf/ftsdfcommon.h (ONE_PIXEL): New macro. | ||
| 335224be | 2022-03-03 16:33:40 | [sfnt] Fix bounds check in SVG. The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not protected by parentheses. As a result, the expression `table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to `table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected `table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect bounds check which may lead to reading past the end of the `SVG ` table. * src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in parentheses. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179 | ||
| 034e5dbf | 2022-02-22 20:37:43 | [psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259 | ||
| 6c5522c6 | 2022-02-19 13:37:07 | * src/bdf/README: Updated. | ||

| 5b26e92a | 2022-02-19 05:26:53 | src/sfnt/ttkern.c (tt_face_load_kern): Micro-optimize. A kerning table can be handled by binary search if it has equal entries. Fixes #1132. | ||
| 00ae29fc | 2022-02-12 23:42:08 | [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value. Before the change, the hinting engine frequently confused horizontal stem and serif hints making some stems too thin and some serifs too thick. The value was tuned using serif fonts from the URW+ base 35 collection. * src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/. | ||
| 338b4e88 | 2022-02-11 19:32:49 | [type42] Fix `FT_Get_PS_Font_Private` for this format. Since Type42 fonts don't have a 'Private' dictionary, the return value should be `FT_Err_Invalid_Argument`. * src/type42/t42drivr.c (t42_ps_get_font_private): Removed. (t42_service_ps_info): Updated. | ||
| 1680885a | 2022-02-09 16:41:07 | [pshinter] Clear reused mask. In PS hinter, memory allocations persist until the module is done. Therefore, we have to clear reused masks. * src/pshinter/pshrec.c (ps_mask_table_alloc): Clear reused mask. | ||
| 0447df71 | 2022-02-09 15:04:58 | [pshinter] Use unsigned indices. This reduces casting and eliminates some checks. * src/pshinter/pshrec.c (ps_mask_test_bit, ps_mask_table_merge, ps_dimension_add_t1stem, ps_hints_t1stem3): Updated. (ps_dimension_add_counter): Updated, unnecessary checks removed. | ||
| ed0e2e76 | 2022-02-08 16:35:14 | [pshinter] Fix mask merging. We forgot to update the number of bits when merging a larger mask into a smaller one. This fix might have rendering effects. * src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number of bits from a larger mask. There is no need to zero unused bits, already zeroed during allocation. (ps_mask_clear_bit): Removed. (ps_mask_ensure): Minor. | ||
| 7c6b2f20 | 2022-02-08 14:37:34 | [pshinter] Revise the hint table handling. * src/pshinter/pshrec.c (ps_hint_table_ensure): Remove redundant size check; avoid array zeroing because it is fully initialized when used. (ps_hint_table_alloc): Fix off-by-one comparison and remove another zeroing of the array elements. |
