217 [base] 'close' callback may not use `stream->memory`.
219 The documentation for `FT_StreamRec::memory` states that it 'shouldn't be
220 touched by stream implementations'. This is true even for internal
221 implementations of the 'close' callback, since it is not guaranteed that
222 `memory` will even be set when the 'close' callback occurs.
224 * src/base/ftobjs.c (new_memory_stream): stash current `memory` in
225 `stream->descriptor`.
226 (memory_stream_close): Use it.
228 2023-01-17 Ben Wagner <bungeman@chromium.org>
230 [base] Always close user-provided stream.
232 The `FT_Open_Face` documentation states
234 > If `FT_OPEN_STREAM` is set in `args->flags`, the stream in `args->stream`
235 > is automatically closed before this function returns any error (including
236 > `FT_Err_Invalid_Argument`).
238 However, if the user provides a stream in `args.stream` with
239 `FT_OPEN_STREAM` set and a `close` function, but then for some reason passes
240 NULL for `aface` and a non-negative `face_index`, the error
241 `Invalid_Argument` is returned but the `close` callback will not be called
242 on the user-provided stream. This may cause resource leaks if the caller is
243 depending on the `close` callback to free resources.
245 The difficulty is that a user may fill out a `FT_StreamRec` and pass its
246 address as `args.stream`, but the stream isn't really 'live' until
247 `FT_Stream_New` is called on it (and `memory` is set). In particular, it
248 cannot really be cleaned up properly in `ft_open_face_internal` until the
249 stream pointer has been copied into the `stream` local variable.
251 * src/base/ftobj.c (ft_open_face_internal): Ensure that user-provided
252 `args.stream.close` is called even with early errors.
254 2023-01-17 Ben Wagner <bungeman@chromium.org>
256 [base] Fix leak of internal stream marked external.
258 `open_face_from_buffer` allocates a new `FT_Stream` to pass to
259 `ft_open_face_internal`. Because this is an `FT_OPEN_STREAM`,
260 `ft_open_face_internal` will mark this as an 'external stream', which the
261 caller must free. However, `open_face_from_buffer` cannot directly free it
262 because the stream must last as long as the face. There is currently an
263 attempt at this by clearing the 'external stream' bit after
264 `open_face_from_buffer` returns successfully. However, this is too late as
265 the original stream may have already been closed and the stream on the face
266 may not be the same stream as originally passed.
268 It is tempting to use `FT_OPEN_MEMORY` and let `ft_open_face_internal`
269 create the stream internally. However, with this method there is no means
270 to pass through a 'close' function to the created stream to free the
271 underlying data, which must be owned by the stream.
273 A possibility is to check on success if the stream of the face is the same
274 as the original stream. If it is then unset the external flag. If not,
275 then free the original stream. Unfortunately, while no current
276 implementation does so, it is possible that the face still has the original
277 stream somewhere other than as the `FT_FaceRec::stream`. The stream needs
278 to remain available for the life of the face or until it is closed,
279 whichever comes earlier.
281 The approach taken here is to let the stream own itself. When the stream is
282 closed it will free itself.
284 * src/base/ftobjs.c (memory_stream_close): Free `stream`.
285 (open_face_from_buffer): Simplify error handling, since
286 `ft_open_face_internal` always closes `args.stream` on any error.

331 [truetype] Reset cvt and storage in context load.
333 Currently the cvt and storage are saved and restored in `TT_RunIns`.
334 However, this is too granular as the cvt and storage area should be set to
335 the original cvt and storage area only when setting up the hinting context.
336 This allows for the cvt and storage area to be modified while parsing
337 multiple glyphs, as is the case with composite glyphs.
339 * src/truetype/ttinterp.h (TT_ExecContextRec): Remove `origCvt` and
340 `origStorage`.
342 * src/truetype/ttinterp.c (TT_RunIns): Don't save and restore the cvt and
343 storage area.
344 (Modify_CVT_Check, Ins_WS): Switch from "if in glyph and using original data
345 do copy on write" to "if in glyph and not using glyph specific data do copy
346 on write".
348 2023-01-06 Matthias Clasen <mclasen@redhat.com>
350 [autofit] Don't depend on 'hb-ft'.
352 The circular dependency is still there, but at least we no longer depend on
353 the HarfBuzz API that is only present if HarfBuzz has been built with
354 FreeType support, making the bootstrapping a bit easier.
356 * src/autofit/ft-hb.c, src/autofit/ft-hb.h: New files, providing
357 `_hb_ft_font_create`, which is more or less a verbatim copy of the
358 corresponding HarfBuzz code from file `hb-ft.cc`.
360 * src/autofit/afglobal.c (af_face_globals_new): Use it.
361 * src/autofit/afshaper.h: Don't include `hb-ft.h` but `ft-hb.h`.
362 * src/autofit/autofit.c: Include `ft-hb.c`.
364 * LICENSE.TXT: Updated.
366 2023-01-06 Ben Wagner <bungeman@chromium.org>
368 [truetype] Keep variation store consistent.
370 `tt_var_load_item_variation_store` fills out a `GX_ItemVarStore`. While it
371 may return an error, the item store must be left in a consistent state so
372 that any use or destruction of the item store can properly use or free the
373 data in it. Before this change the counts from the font data were read
374 directly into the item store before the actual allocation of the arrays to
375 which they referred. There exist many opportunities between the time the
376 counts are read and the arrays are allocated to return early due to invalid
377 data. When this happened the item store claimed to have entires it actually
378 did not, leading to crashes later when it was used.
380 Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54449
382 * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Read the counts
383 into local variables and store them in the item store only after the related
384 arrays are actually created on the item store.
386 2023-01-05 Ben Wagner <bungeman@chromium.org>
388 [base] Report used stream's external status.
390 In `open_face` the initial stream is set on the face, along with the
391 information about if FreeType is the owner of the stream object itself. The
392 loaders may in the course of their work replace this stream with a new
393 stream (as is the case for 'woff' and 'woff2'), which may have a different
394 ownership than the initial stream object (likely the original stream object
395 is owned by the user and is external, while the new stream object is created
396 internally to FreeType and is internal). When the stream is replaced, the
397 face's flags are updated with the new ownership status.
399 However, `open_face` cannot itself free this stream as its caller
400 `ft_open_face_internal` is responsible for this. In addition, in the case
401 of an error `open_face` cannot return an actual face with the new stream and
402 its ownership status to the caller. As a result, it must pass this
403 information back to the caller as a sort of "failed face" so that the caller
404 can clean up.
406 `open_face` was already passing back the new stream but was not passing back
407 the stream ownership information. As a result the stream may not have been
408 free'd when needed.
410 Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54700
412 * src/base/ftobjs.c (open_face): Pass back the ownership information as

613 [truetype] Restore behavior of ft_var_load_hvvar
615 * src/truetype/ttgcvar.c (ft_var_load_hvvar): restore previous behavior
617 In a previous change [0] the behavior of `ft_var_load_hvvar` was changed
618 to not load the item variation store if it was at offset 0, but not
619 return an error when this happened. This broke any users, like
620 `tt_hvadvance_adjust`, that rely on successful completion of
621 `ft_var_load_hvvar` to imply that returned table's `itemStore` had been
622 initialized. This lead such users to dereference NULL.
624 This change appears to have been unintentional and unrelated to the
625 actual avar2 changes. As a result, fix these NULL dereferences by
626 restoring the code to always attempt to initialize the `itemStore`.

656 * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Accelerate the search.
658 This is mostly for consistency because PFR fonts with bitmap strikes
659 do not seem to exist.
661 2022-11-06 Alexei Podtelezhnikov <apodtele@gmail.com>
663 [bdf, pfr, psnames] Accelarate charmap searches.
665 The binary searches within charmaps can be accelerated because they
666 often contain dense continuous blocks of character codes. Within such
667 blocks, you can predict matches based on misses. This method has been
668 deployed in `bdf` since 0f122fef34; we only refactor it there. We now
669 use it in `pfr` and `psnames`, which speeds up the unicode charmap
670 access by about 50% in PFR and Type 1 fonts.
672 * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Refactor.
673 * src/pfr/pfrcmap.c (pfr_cmap_char_{index,next}): Predict `mid` based

681 See
683 https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
685 for the specification.
687 Currently, this is implemented only in most recent OS versions on Apple
688 platforms and in the HarfBuzz library, but it is expected to be added to the
689 OpenType standard soon.
691 * src/truetype/ttgxvar.h (GX_AVarTableRec): New structure.
692 (GX_BlendRec): Use it to replace `avar_segment` with `avar_table`.
694 * src/truetype/ttgxvar.c (ft_var_load_avar): Load new table version.

755 whether it allows reading the format byte, each successive paint table field
756 read need to be bounds-checked before reading further values.

1142 [pfr] Fortify the kerning code.
1144 Any array index must be strictly less then the array size. Therefore,
1145 we must reject indexes that are equal to the array size. Alternatively,
1146 we should move the bounds check before the index decrement but that
1147 would be confusing.
1149 In addition, it is ok to decrement zero (.notdef) and get UINT_MAX,
1150 which is then automatically rejected in the bounds check.
1152 * src/pfr/pfrobjs.c (pfr_face_get_kerning): Fix the bounds checking.

1175 [base] Build outlines in amortized constant time.
1177 When resizing the loader's points and contours, resize them to at least 1.5
1178 times their current size. The code currently only reserves as much space as
1179 is currently required, leading to O(n^2) runtime when adding points one at a
1180 time.
1182 This change does not attempt to ever shrink the loader's point and contour
1183 storage since this was not attempted previously either. The 1.5 multiple
1184 was chosen as a trade-off between potentially unused space and the runtime.
1186 * src/base/ftgloader.c (FT_GlyphLoader_CheckPoints): Implement it.
1188 Fixes #1173.

1267 of 'COLR' v1 variation formats (in follow-up commits).
1269 (read_paint): Add `face` parameter; update caller.

1281 doc: Clarify description of `FT_Stream_IoFunc`.
1283 The existing documentation comments on `FT_Stream_IoFunc` hinted at the dual
1284 seek/read behavior required for custom stream implementations to work, but
1285 it didn't explicitly explain it. Without looking at the internals of
1286 FreeType, it was easy for someone to assume their implementation should
1287 handle both seek and read operations all the time. If this is done, you get
1288 a variety of errors, but mostly just `Unknown_File_Format` (error code
1289 0x02).
1291 2022-07-04 Dominik Röttsches <drott@chromium.org>
1293 [sfnt] Load variation store for 'COLR' v1.

1299 (tt_face_load_colr, tt_face_free_colr) [VARIABLE_COLRV1_ENABLED]: Load and
1300 free variation store data using the functions from the Multiple Masters
1301 service.
1303 2022-07-03 Chris Liddell <chris.liddell@artifex.com>
1305 [base] Improve error handling in `FT_GlyphLoader_CheckPoints`.
1307 If `FT_GlyphLoader_CreateExtra` returns an error (and a couple of other
1308 places), `FT_GlyphLoader_CheckPoints` would propagate the error immediately,
1309 rather than cleaning up the partially set up `FT_GlyphLoader`. As a
1310 consequence, a subsequent attempt to create a glyph could result in a crash.
1312 * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Ensure all the error
1313 conditions exits are consistent, eventually calling `FT_GlyphLoader_Reset`.
1315 2022-07-03 Thomas Sondergaard <thomas@sondergaard.cc>
1317 CMakeLists.txt: Provide both 'freetype' and 'Freetype::Freetype' targets.
1319 FreeType can be located by consuming projects that use
1320 `find_package(Freetype)` either via the old `MODULE` path (which uses
1321 `FindFreetype.cmake` supplied by CMake), or via the new `CONFIG` path (which
1322 uses `freetype-config.cmake` as supplied by this project). Up to this point
1323 the CMake module has supplied the target `Freetype::Freetype` and the config
1324 file provided by this project the target `freetype`. Now we supply both
1325 `freetype` and `Freetype::Freetype` so that consuming projects can always
1326 use the target `Freetype::Freetype` regardless of what path was taken by
1327 `find_package(Freetype)`.

1422 [meson] Disable FreeType in HarfBuzz fallback.
1424 This avoids cyclic subproject configuration when the 'harfbuzz' feature is
1425 enabled, or `--wrap-mode=forcefallback` is used, but HarfBuzz is built as a
1426 subproject. HarfBuzz does the same and disables HarfBuzz support when
1427 configuring FreeType as a subproject.
1429 * meson.build (harfbuzz_dep): Implement it.
1431 * subprojects/harfbuzz.wrap: New file.
1433 * .gitlab-ci.yml [windows meson]: Use latest version of the meson 0.59
1434 series, which has a necessary bug fix to make CI work.

1438 [truetype] Clean up phantom point accounting.
1440 This formalizes that the phantom points appended in the outline
1441 do not increase its point count, nor are they tagged or included
1442 in any additional contours. Only their coordinates are stored.
1443 They are counted in the glyph zone, however.
1445 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Infer `n_points`
1446 from the outline size plus four phantom points.
1447 * src/truetype/ttgxvar.h (TT_Vary_Apply_Glyph_Deltas): Remove this
1448 argument.

1463 2022-06-18 Ben Wagner <bungeman@chromium.org>
1465 [stream] Fix reading s32 when long is s64
1467 `FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return
1468 negative values when `long` is more than 32 bits. `FT_Stream_ReadULong`
1469 would read four bytes into the LSB of an `FT_ULong` and return that.
1470 Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is
1471 more than 32 bits the cast to `FT_Long` never resulted in a negative
1472 value.
1474 Fix this by modifying `FT_Stream_Read*` to return a type of the same
1475 size as the bytes it is reading and changing the `FT_READ_*` and
1476 `FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*`
1477 but with the correctly signed type (instead of casting to what is
1478 assumed to be the type of `var` which will happen automatically anyway).
1480 There exist a few cases like with the `OFF3` variants where there isn't
1481 generally a type with the correct size. `FT_PEEK_OFF3` works around this
1482 loading the bytes into the three most significant bits and then doing a
1483 signed shift down. `FT_NEXT_OFF3` also already worked correctly by
1484 casting this signed value to another signed type. `FT_Stream_GetUOffset`
1485 works correctly but one must be careful not to attempt to cast the
1486 returned value to a signed type. Fortunately there is only
1487 `FT_GET_UOFF3` and no `FT_GET_OFF3`.
1489 All of these cases are handled correctly when reading values through
1490 `FT_Stream_ReadFields` since it generically computes the signed value
1491 through an `FT_Int32`. This change is essentially doing the same for
1492 these macros.
1494 * include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*):
1495 Update macros and return types to use fixed size types for fixed size
1496 values.

1517 [type1] Directly search for eexec in private dict
1519 This code originally just searched for `eexec`. This was later modified
1520 to check that the `eexec` found is valid (not in a string or comment).
1521 This was done by searching for `eexec` as before and then, for each
1522 `eexec` found, searching from the beginning using the correct parsing to
1523 see if the `eexec` was still found. If the private dictionary is large
1524 and contains many copies of `eexec` which are not valid, the initial
1525 part of the private dictionary is scanned once for each, potentially
1526 leading to n^2 parsing time.
1528 Instead of finding an initial `eexec` and then re-parsing to discover if
1529 it is valid, drop the initial search for `eexec` and just parse to find
1530 a valid `eexec`. This is strictly faster since the validation must
1531 happen anyway and avoids restarting from the beginning each time an
1532 `eexec` is found in the data.
1534 * src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing

1551 [gzip] Handle inflate returning Z_NEED_DICT
1553 When `inflate` returns `Z_NEED_DICT` this is currently not reported as
1554 an error and callers may assume that the decompression succeeded when it
1555 did not. In particular, a compressed table in a woff file may not
1556 actually be decompressed and written as expected, leaving the backing
1557 memory for the expanded table uninitialized.

1619 document the ownership flag on the glyph slot was set to true but never
1620 set to false. As a result after loading a compressed document a glyph
1621 from an uncompressed document would load fine, but when this glyph slot

1658 [truetype] Handle 0xFFFF special value inside delta retrieval function
1660 * truetype/ttgxvar.c (tt_hvadvance_adjust, tt_apply_mvar,
1661 tt_var_get_item_delta): Remove special 0xFFFF handling in favor of less
1662 redundant handling inside the tt_var_get_item_delta function, as it is
1663 equivalent to returning a 0 delta. Avoids code-duplication checking for
1664 special value 0xFFFF.
1666 2022-05-19 Dominik Röttsches <drott@chromium.org>
1668 [truetype, snft] Add service methods for `DeltaSetIdxMap` and `VarStore`.
1670 This will be needed for 'COLR' v1 variation support.
1672 * src/truetype/ttgxvar.h (GX_ItemVarData, GX_AxisCoords, GX_VarRegion,
1673 GX_VarItemStore, GX_DeltaSetIdxMap): Move structures to...
1674 * include/freetype/internal/ftmmtypes.h: ... this new file.
1676 * include/freetype/internal/service/svmm.h (MultiMasters): Include
1677 `ftmmtypes.h`.
1678 (FT_Var_Load_Delta_Set_Idx_Map_Func, FT_Var_Load_Item_Var_Store_Func,
1679 FT_Var_Get_Item_Delta_Func, FT_Var_Done_Item_Var_Store_Func,
1680 FT_Var_Done_Delta_Set_Idx_Map_Func): New function typedefs.
1681 (MultiMasters): Add them.
1682 (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated.
1684 * src/cff/cffdrivr.c (cff_load_item_variation_store,
1685 cff_load_delta_set_index_mapping, cff_get_item_delta,
1686 cff_done_item_variation_store, cff_done_delta_set_index_map): New wrapper
1687 methods calling into mm service.
1688 (cff_service_multi_masters): Updated.
1690 * src/truetype/ttgxvar.c (ft_var_load_item_variation_store,
1691 ft_var_load_delta_set_index_mapping, ft_var_get_item_delta,

1706 [truetype] Move deallocation of `DeltaSetIdxMap` into own function.
1708 This is a preparation for handling `DeltaSetIdxMap` and `VarStore` as a
1709 FreeType service.
1711 * src/truetype/ttgxvar.c (ft_var_done_delta_set_index_map): New function.
1712 (tt_done_blend): Use it.
1714 2022-05-18 Werner Lemberg <wl@gnu.org>
1716 * builds/toplevel.mk (do-dist): Don't remove meson wrap files.
1718 Fixes #1157.
1720 2022-05-18 Werner Lemberg <wl@gnu.org>
1722 * subprojects/zlib.wrap: Update to zlib version 1.2.12.
1724 2022-05-18 Werner Lemberg <wl@gnu.org>
1726 REAMDE: Mention that gitlab's 'download' button doesn't work.
1728 This is because the `git archive` command doesn't preserve submodules.
1730 Note that currently there is no support for disabling the 'download' button
1731 in gitlab (https://gitlab.com/gitlab-org/gitlab/-/issues/17032).
1733 Fixes issue #1158.
1735 2022-05-11 Werner Lemberg <wl@gnu.org>
1737 [truetype] Handle inner/outer index values 0xFFFF/0xFFFF.
1739 This was introduced in OpenType 1.8.4.

1768 2022-04-30 Anuj Verma <anuj@posteo.net>
1770 [sdf] Do not throw errors for invisible glyphs.
1772 * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Return `FT_Err_Ok` if
1773 width or height is zero, since some glyphs do not generate visible bitmaps.
1775 Fixes #1150.
1777 2022-04-30 Werner Lemberg <wl@gnu.org>
1779 * src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_COLOR` for SVG fonts.
1781 Fixes #1151.
1783 2022-04-27 Brendan Shanks <bshanks@codeweavers.com>
1785 autogen.sh: Fix building when freetype is itself a git submodule.
1787 There are situations where .git is not a directory, like when
1788 freetype is a submodule in another repository.
1790 2022-04-26 Alexei Podtelezhnikov <apodtele@gmail.com>
1792 [builds/windows] Simplify non-desktop UWP check.
1794 Fixes mingw compilation described in !159.
1796 * builds/windows/ftsystem.c: Do not use WINAPI_FAMILY_PARTITION macro.
1798 2022-04-25 Alexei Podtelezhnikov <apodtele@gmail.com>
1800 [truetype] Reset IUP flags in `TT_RunIns`.
1802 Fixes #1148 by moving the flag initialization back, partly reverting
1803 7809007a and fd03dcc1. Initializing these flags elsewhere skips 'cvt'.
1805 * src/truetype/ttinterp.c (TT_RunIns): Initialize the IUP flag here...
1806 (TT_Run_Context): ... instead of here.
1808 2022-04-24 Xavier Claessens <xavier.claessens@collabora.com>
1810 [meson] Remove `default_library=both` from `default_options`.
1812 It is inconsistent with what all other Meson projects do.
1814 It also prevents static linking to FreeType when it is a subproject because
1815 `default_options` in a subproject takes precedence on values set on the main
1816 project. For example, building 'GStreamer' with `-Ddefault_library=static`
1817 would still dynamically link on FreeType unless the user also sets
1818 `-Dfreetype2:default_library=static`.
1820 * meson.build: Updated.
1822 * .gitlab-ci.yml: Retain `both` option for testing.
1824 2022-04-19 Werner Lemberg <wl@gnu.org>
1826 * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Integer overflow.
1828 Reported as
1830 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=46792
1832 2022-04-16 Georg Brandl <georg@python.org>
1834 * src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_SVG]: Fix segfault.
1836 This can happen if the function is called with `size` being `NULL`.
1838 Fixes #1147.
1840 2022-04-14 Steve Lhomme <robux4@ycbcr.xyz>
1842 .gitlab-ci.yml: Add a Universal Windows build target
1844 It's compiled for Windows 10 and up, ensuring UNICODE is set (default for UWP)
1845 and selecting the proper WINAPI_FAMILY (WINAPI_FAMILY_APP).
1847 Do not try to run the UWP exe in the Docker as it doesn't work.
1849 2022-04-04 Ben Wagner <bungeman@chromium.org>
1851 [sfnt] Correct FT_ColorStopIterator documentation.
1853 * include/freetype/ftcolor.h (FT_ColorStopIterator): the user should not
1854 set `p` to NULL before calling `FT_Get_Colorline_Stops`. `p` and
1855 `num_color_stops` are set by `FT_Get_Paint`. `p` and
1856 `current_color_stop` are updated by `FT_Get_Colorline_Stops`.
1858 2022-04-01 Werner Lemberg <wl@gnu.org>
1860 * builds/unix/configure.raw: Add option `--with-librsvg`.
1862 Since 'librsvg' is written in Rust, this option allows distributions to
1863 avoid a dependency on the entire Rust toolchain to provide the FreeType demo
1864 programs.
1866 Suggested by Lars Wendler in !156.
1868 2022-04-01 Werner Lemberg <wl@gnu.org>
1870 * src/sfnt/sfwoff.c (reconstruct_glyf): Fix gcc 10 warning.

1876 2022-04-01 Eric Jing <@CPUcontrol>
1878 CMakeLists.txt: Fix `Info.plist` path.
1880 When building a framework using CMake with `add_subdirectory`, CMake must be
1881 able to find `freetype-Info.plist` when configuring the framework
1882 properties.
1884 Fixes #1145.

1950 Whitespace.
1952 2022-03-30 Werner Lemberg <wl@gnu.org>
1954 [builds] Fix creation of `freetype2.pc` for static-only builds.
1956 We have to help `pkg-config` since it can't recognize that there is no
1957 shared library installed.
1959 Note that meson already does exactly the same.
1961 * builds/unix/configure.raw (REQUIRES_PRIVATE, LIBS_PRIVATE): Rename to...

1983 This is another bit to handle 'sbix' tables as described in the OpenType
1984 specification.
1986 * include/freetype/ftparams.h (FT_PARAM_TAG_IGNORE_SBIX): New macro.
1988 * src/sfnt/sfobjc.c (is_apple_sbix): Rename to...
1989 (has_sbix): ... this.
1990 Check for more sbit tables.
1991 Handle `FT_PARAM_TAG_IGNORE_SBIX` to eventually control `has_sbix`.
1992 Only call sbit table loader if an sbit table is present.
1994 2022-03-25 Werner Lemberg <wl@gnu.org>
1996 [truetype] Fix 'sbix' table handling.
1998 * src/sfnt/ttsbit.c (tt_face_load_sbix_image): Correct calculation of
1999 'metrics->horiBearingY'.
2000 Set vertical metrics.

2013 2022-03-25 Werner Lemberg <wl@gnu.org>
2015 Add `FT_FACE_FLAG_SBIX` and `FT_HAS_SBIX`.
2017 Fonts with 'sbix' tables need special handling by the application.

2021 * src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix'
2022 table is present.
2024 2022-03-25 Werner Lemberg <wl@gnu.org>
2026 * include/freetype/freetype.h (FT_LOAD_SBITS_ONLY): Tag macro as public.

2047 2022-03-20 Ben Wagner <bungeman@chromium.org>
2049 [woff2] Support overlap flag for simple glyphs.
2051 In the woff2 spec it has been proposed to allow the OVERLAP_SIMPLE flag
2052 to be retained through the woff2 format [0].
2054 [0] https://www.w3.org/TR/WOFF2/#glyf_table_format
2056 * src/sfnt/sfwoff2.h (GLYF_OVERLAP_SIMPLE): add glyf flag.
2058 * src/sfnt/sfwoff2.c (reconstruct_glyf): parse optionFlags and
2059 overlapSimpleBitmap[]. (store_points): set OVERLAP_SIMPLE on first point's
2060 flag if the overlap bit is set.
2062 2022-03-19 Werner Lemberg <wl@gnu.org>
2064 [cff] Synchronize `cff_slot_load` with `TT_Load_Glyph`.

2108 [sdf] Fix corner checks and improve performance.
2110 * src/sdf/ftsdf.c (sdf_generate_bounding_box): Always check for a corner if
2111 two distances (for different curves) are very close.
2113 (sdf_conic_to): Check whether the conic curve can be treated as a line
2114 (which happens if the control point coincides with any end point).
2116 2022-03-05 Anuj Verma <anuj@womp.xyz>
2118 [sdf] Implement deviation-based splitting for Bezier curves.
2120 * src/sdf/ftsdf.c (split_sdf_cubic, split_sdf_shape): Add checks to figure

2130 2022-03-03 Ben Wagner <bungeman@chromium.org>
2132 [sfnt] Fix bounds check in SVG.
2134 The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not
2135 protected by parentheses. As a result, the expression
2136 `table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
2137 `table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
2138 `table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
2139 bounds check which may lead to reading past the end of the `SVG ` table.
2141 * src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in
2142 parentheses.
2144 Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179
2146 2022-02-23 Ben Wagner <bungeman@chromium.org>
2148 [psaux] Full bounds check for OtherSubr 19.
2150 It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
2151 NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
2152 `blend->num_designs` set to 2, and the user supplied `idx` to be large (for
2153 example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds
2154 check overflows in a well defined manner, allowing for an invalid call to
2155 `memcpy`.
2157 In addition, it is possible to call OtherSubr 19 with
2158 `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
2159 that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes
2160 the bounds check (it is logically always fine to copy nothing starting at
2161 index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
2162 by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is
2163 undefined behavior (even if `count` is zero).
2165 * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
2166 `blend->num_designs` can be copied to `decoder->buildchar[idx]`.
2167 Also avoid passing NULL to `ft_memcpy`.

2173 [cmake] Drop the support of CMake 2.x.
2175 * CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer.
2177 The issue #1059 reports the difficulty to support both of
2178 CMake 2.x and newer one by single CMakeLists.txt without
2179 the inflation of cmake_policy() workarounds.

2216 [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value.
2218 Before the change, the hinting engine frequently confused horizontal
2219 stem and serif hints making some stems too thin and some serifs too
2220 thick. The value was tuned using serif fonts from the URW+ base 35
2221 collection.

2266 We forgot to update the number of bits when merging a larger mask
2267 into a smaller one. This fix might have rendering effects.
2269 * src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number
2270 of bits from a larger mask. There is no need to zero unused bits,
2271 already zeroed during allocation.

2407 Document `FT_Outline_Decompose` degenerate segments.
2409 `FT_Outline_Decompose` does not filter out and can return degenerate
2410 segments in an outline. This can be surprising when attemping to
2411 stroke such an outline. Clarify the existing documentation on this
2412 matter to cover all forms of degeneracy (without specifying exactly
2413 how they will be reported), why they might arise, and better explain in
2414 what cases they may be an issue.
2416 * include/freetype/ftoutlin.h (FT_Outline_Decompose): update

2659 2022-01-20 Alexei Podtelezhnikov <apodtele@gmail.com>
2661 [base] Undefined scale means no scale.
2663 It might be surprising that FreeType does not have default ppem and
2664 the size has to be set explicitly or face undefined behavior with
2665 undefined variables and errors. This offers an alternative to
2666 missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined
2667 behavior is bettr than undefined one.
2669 This is alternative to !132 and discussed in
2670 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708

2702 [pshinter] Avoid accessing uninitialized zone.
2704 The `normal_top.count` may be 0, implying no `normal_top.zones` exist.
2705 The code must not access these (non-existent) `normal_top.zones`.
2707 * src/pshinter/pshalgo.c (ps_hints_apply): Do not assume that

2796 Revert "[bzip2] Avoid use of uninitialized memory."
2798 This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6.
2800 The original commit did avoid the use of uninitialized memory. However,
2801 it appears that the original commit is no longer required. The
2802 underlying issue was resolved by a change in freetype2-testing "Build
2803 bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so
2804 bzip2 writes were not tracked or considered initialized. Clearing
2805 `buffer` in the original commit allowed msan to see the `buffer` content
2806 initialized once in FreeType code, but msan saw no writes into buffer
2807 from bzip2. With bzip2 now built with msan, the bzip2 writes are
2808 properly instrumented and msan sees the bzip2 writes into the buffer. As
2809 a result the original commit can be safely reverted to allow for better
2810 detection of other uninitialized data scenarios.

2818 [type42] Track how much type42 ttf data is available.
2820 Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header
2821 data which it expects `t42_parse_sfnts` to fill out from /sfnts data.
2822 However, there is no guarantee that `t42_parse_sfnts` will actually be
2823 called while parsing the type42 data as the /sfnts array may be missing
2824 or very short. This is also confusing behavior as it means
2825 `T42_Open_Face` is tightly coupled to the implementation of the very
2826 distant `t42_parse_sfnts` code which requires at least 12 bytes to
2827 already be reserved in `face->ttf_data`.
2829 `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how
2830 much space is reserved for ttf data instead of traking how much data has
2831 actually been written into `face->ttf_data`. It will also act strangely
2832 in the presense of multiple /sfnts arrays.
2834 * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized
2835 to NULL. Free `ttf_data` on error.
2837 * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and
2838 set it to the actual number of bytes read. Ensure `ttf_data` is freed

3068 [truetype] Reset localpoints when varying cvt.
3070 When iterating over the cvt tuples and reading in the points it is necessary

3072 existing code did not reset `localpoints` to `NULL` when there were no
3073 private point numbers. If the previous tuple did have private point numbers

3107 * meson.build: Optimize lookup for `python3` program.
3109 The python module's `find_installation` method is intended to provide
3110 routines for compiling and installing python modules into the
3111 `site-packages` directory. It does a couple of slow things, including run
3112 an introspection command to scrape sysconfig info from the detected
3113 interpreter, which are not needed for the sole use case of invoking the
3114 found installation as an executable.
3116 Furthermore, when invoked without the name or path of a python binary, it is
3117 hardcoded to always look for `python3` corresponding to the interpreter
3118 meson itself uses to run. So using `find_installation` did not even allow
3119 detecting `python2` as a fallback.
3121 Instead, switch to a simple `find_program` lookup that finishes as soon as
3122 the program is found.
3124 2021-12-17 Eli Schwartz <eschwartz@archlinux.org>
3126 * builds/meson/*.py: Fix name of python executable for auxiliary scripts.
3128 The previous change to check the return code of `run_command` invocations
3129 caused the CI to fail. Although most scripts used `python_exe` as the
3130 program command, the script to determine the project version did not.
3132 But, all scripts used `python` as the shebang, and this is not available on
3133 all systems. Particularly Debian does not provide a `python` command,
3134 though `python3` does exist. This meant that formerly the version number
3135 was lacking, and now the build simply fails.
3137 Instead, rely on `python3` since it is guaranteed to exist when running
3138 meson, and `python2` is end of life anyway.
3140 2021-12-17 Eli Schwartz <eschwartz@archlinux.org>
3142 * meson.build: Check the return value of `run_command`.
3144 By default, errors are not checked and a command that is somehow broken will
3145 just capture incorrect output (likely an empty string). Current development
3146 versions of meson now raise a warning for this implicit behavior, and advise
3147 explicitly setting the `check:` keyword argumend to determine whether a
3148 failing return code should be considered an error.
3150 Since none of the commands in this project are expected to fail, mark them
3151 as required to succeed.

3236 [bdf] Fix use of uninitialized value.
3238 In _bdf_readstream if the data contained no newline then the buffer
3239 would continue to grow and uninitialized data read until either the
3240 uninitialized data contained a newline or the buffer reached its
3241 maxiumum size. The assumption was that the line was always too long and
3242 the buffer had been filled, however this case can also happen when there
3243 is not enough data to fill the buffer.
3245 Correct this by properly setting the cursor to the end of the available

3322 [truetype] Quietly reject out-of-spec `hdmx` tables.
3324 The `hdmx` table is optional and can be safely rejected without
3325 an error if it does not follow specifications. The record size
3326 must be equal to the number of glyphs + 2 + 32-bit padding.

3418 Provide C++ versions for public macros with casts.
3420 Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
3421 macros with C-style casts even for system header files; this also affects
3422 directories included with `-isystem`. While this could be seen as a problem
3423 with g++, the problem is more a philosophical one: Over the time, C and C++
3424 diverged more and more, and some features of C are no longer the 'right'
3425 solution in C++.
3427 * include/freetype/config/public-macros.h (FT_STATIC_CAST,
3428 FT_REINTERPRET_CAST): New macros.

3457 2021-11-16 Werner Lemberg <wl@gnu.org>
3459 [truetype] Updates for the forthcoming OpenType 1.9 standard (1/2).
3461 This is in preparation for implementing `DeltaSetIndexMap` format 1, which

3550 [sfnt] Reduce footprint if WOFF and WOFF2 support is not needed.
3552 Based on a patch from metarutaiga (MR !106). The gist of this commit is
3553 that it doesn't make sense to support WOFF without compression (which would
3554 be only possible in WOFF 1.0 anyway).
3556 * src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with

3590 [dlg] Define DLG_STATIC explicitly.
3592 DLG_STATIC is intended to disable Windows DLL linking attributes.
3593 It does not hurt to define it explicitly when we wrap DLG code.
3594 This fixes tons of LNK4286 and C4273 warnings from MSVC if we
3595 forget to define DLG_STATIC as a compiler option.
3597 * builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option.
3598 * src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC.

3605 The DLG wrapper needs to know if FT_DEBUG_LOGGING is defined in

3620 [truetype] Fix handling of packed deltas in Variation Fonts.
3622 * src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of
3623 bytes used to encode the deltas to be higher than the number of encoded
3624 values. The specification allows a very compact encoding; for example, a
3625 list of 200 zeros can be encoded with just a couple of bytes.
3627 We now count the consumed bytes to make sure to not read more than expected.

3634 `ft_var_readpackedpoints`, when it returns `ALL_POINTS`, also sets
3635 `point_count` to value 0. However, the CVAR code was incorrectly expecting
3636 that `point_count` would be set to match the length of the CVT table.

3729 [mm] Tolerate missing Blend dictionary entries
3731 In a Multiple Master font, the Blend dictionary must contain valid
3732 Private, FontInfo, and FontBBox. The current code will error if any of
3733 these are present and invalid, but will not error and will provide
3734 uninitialized data if the Blend dictionary exists but does not contain
3735 one of these entries. This change reverts to the older behavior of
3736 treating any missing entries as containing all zero data and not
3737 returning an error.
3739 In the future it may be best to keep track of when these are actually
3740 initialized and error if they are not.

3773 [mm] Delay setting blend weight and design position.
3775 Previously the `blend->weight_vector`, `blend->default_weight_vector`,
3776 and `blend->design_pos` were set early to allocated but uninitialized
3777 memory under the assumption that the memory would eventually be
3778 initialized. However, it is possible that some of the required
3779 keywords may not actually be present, leaving the memory uninitialized.
3780 This is different from a present but invalid table, which would produce
3781 an error.

3804 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104
3806 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts
3807 into locals and update the vstore counts immediately after each entry
3808 becomes free-able.
3810 2021-10-20 Ben Wagner <bungeman@chromium.org>
3812 [sfnt] Delay setting gasp ranges and count until computed.
3814 Previously, the gasp.numRanges was set and gasp.gaspRanges was
3815 allocated and assigned before a possible early exit if the frame could
3816 not be entered. It is also possible that the gaspRanges allocation
3817 could fail but the numRanges still be set to non-zero. In such cases
3818 an error would be returned, but the face would have a gasp in an
3819 inconsistent state which may still be accessed.
3821 Reported as
3822 https://bugs.chromium.org/p/chromium/issues/detail?id=1261450
3824 * src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges
3825 and gasp.gaspRanges until after the ranges are initialized.
3827 2021-10-20 Ben Wagner <bungeman@chromium.org>
3829 [sfnt] Delay setting names and langTags until computed.
3831 Previously, the table->names and table->langTags fields were created
3832 pointing to uninitialized memory and an early exit could happen if the
3833 frame could not be entered. The caller would then be unable to properly
3834 dispose of the memory as the string fields had not been initialized.
3836 Reported as
3837 https://bugs.chromium.org/p/chromium/issues/detail?id=1261343
3839 * src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags
3840 and table->names until after the memory they will point to is fully
3841 initialized.
3843 2021-10-20 Alexei Podtelezhnikov <apodtele@gmail.com>
3845 * tests/issue-1063/main.c: s/PATH_MAX/FILENAME_MAX/.
3847 Closes !97 for Windows by using a standard macro.
3849 2021-10-19 Werner Lemberg <wl@gnu.org>
3851 [bdf, cid, pfr, winfonts] Improve rejection of other font formats.
3853 This is mainly for better diagnostics of malformed fonts.
3855 * src/bdf/bdflib.c (_bfd_readstream): Stop font format testing if the first
3856 input line is too long or doesn't end with `\r` or `\n`.
3858 * src/cid/cidparse.c (cid_parser_new): Don't handle too short input as an
3859 error but as an unknown format.
3861 * src/pfr/pfrobjs.c (pfr_face_init): Ditto.
3863 * src/winfonts/winfnt.c (fnt_font_load, fnt_face_get_dll_font): Ditto.
3865 2021-10-19 Alexei Podtelezhnikov <apodtele@gmail.com>
3867 [pcf] Zero out the allocated properties.
3869 Fallout reported as
3870 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40033
3872 * src/pcf/pcfread.c (pcf_get_properties): Use FT_NEW_ARRAY and zero
3873 out `properties` in case of failure.
3875 2021-10-18 Werner Lemberg <wl@gnu.org>
3877 configure: Use string comparison for directory inodes.
3879 Inode values might be larger than integers supported by the shell.
3881 Fixes #1105.
3883 2021-10-17 Alexei Podtelezhnikov <apodtele@gmail.com>
3885 * src/sfnt/ttload.c (tt_face_load_name): NULL-initialize langTag.

3897 * src/bdf/bdflib.c (_bdf_add_property): Cosmetic NULL.
3898 (bdf_create_property): Limit allocations to customary signed
3899 FT_Long and NULL-initialize unused storage.
3900 (bdf_free_font): Do not free unused storage.
3902 2021-10-17 Alexei Podtelezhnikov <apodtele@gmail.com>
3904 * src/sfnt/ttload.c (tt_face_load_name): Accounting fix.

3909 2021-10-16 Ben Wagner <bungeman@chromium.org>
3911 Fix typos in memory macros.
3913 FT_QNEW_ARRAY and FT_QRENEW_ARRAY were using the non-Q
3914 FT_MEM_NEW_ARRAY and FT_MEM_RENEW_ARRAY. Change these to use the Q
3915 versions. Also fix the one issue discovered in tt_face_load_name
3916 where table->names is created with FT_QNEW_ARRAY but the extra
3917 string member is not initialized to NULL.
3919 * include/freetype/internal/ftmemory.h (FT_Q(RE)NEW_ARRAY):
3920 Use FT_MEM_Q(RE)NEW_ARRAY as needed.
3922 * src/sfnt/ttload.c (tt_face_load_name): Initialize `entry->string`.
3924 2021-10-15 Ben Wagner <bungeman@chromium.org>
3926 [truetype] Reload context after re-executing `prep`.
3928 When a different hinting mode from the current is selected, the `prep` table
3929 must be re-executed with the new mode. After this happens the context must
3930 be re-loaded in preparation for the glyph program to be run.
3932 Fixes #1104.
3934 * truetype/ttgload.c (tt_loader_init): Add call to `TT_Load_Context`.
3936 2021-10-15 Werner Lemberg <wl@gnu.org>
3938 [truetype] Minor documentation improvements.

3962 2021-10-11 Alexei Podtelezhnikov <apodtele@gmail.com>
3964 [psaux] Signedness revisions.
3966 Unsigned indexes are easier to check.
3968 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings): Updated.

3973 2021-10-11 Alexei Podtelezhnikov <apodtele@gmail.com>
3975 [cid] Signedness revisions.
3977 Unsigned checks are simpler.
3979 * include/freetype/t1tables.h (CID_FaceInfoRec): Change to unsignd
3980 `num_dicts`.
3981 * src/cid/cidparse.h (CID_Parser): Change to unsigned `num_dict`.

3984 * src/cid/cidload.c (cid_load_keyword, parse_fd_array,
3985 parse_expansion_factor, parse_font_name, cid_read_subrs,
3986 cid_face_open): Updated.
3987 * src/cid/cidobjs.c (cid_face_done): Updated.

4002 2021-10-08 Alexei Podtelezhnikov <apodtele@gmail.com>
4004 Signedness revisions.
4006 This eliminates explicit casting by switching to unsigned fields.
4007 The revisions mostly impact the handling of CID fonts.
4009 * include/freetype/fttypes.h (FT_Data): Change to unsigned `length`.
4010 * include/freetype/t1tables.h (CID_FaceDictRec): Ditto for `sd_bytes`.
4011 (CID_FaceInfoRec): Ditto for `gd_bytes` and `gd_bytes`.
4012 * include/freetype/internal/tttypes.h (TT_LoaderRec): Ditto for
4013 `byte_len`.
4015 * src/cid/cidgload.c (cid_load_glyph): Updated.
4016 * src/cid/cidload.h (cid_get_offset): Update argument.

4022 * src/truetype/ttgload.c (TT_Process_Composite_Glyph,
4023 load_truetype_glyph): Updated.
4025 2021-10-07 Jan Alexander Steffens (heftig) <jan.steffens@gmail.com>
4027 meson.build (gen_docs): Use `current_source_dir` instead of `source_root`.
4029 These two are not equal when FreeType is used as a subproject, such as in
4030 `freetype-demos`. In that case, `source_root` points at the root project,
4031 causing the docs build to fail.
4033 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com>
4035 * src/smooth/ftgrays.c (FT_DIV_MOD): Limit the ARM workaround.
4037 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com>
4039 [builds/unix, builds/vms] Standardize `mmap` failure.
4041 * builds/unix/ftsystem.c (FT_Stream_Open): Check for MAP_FAILED.
4042 * builds/vms/ftsystem.c (FT_Stream_Open): Ditto.
4044 This should cover https://savannah.nongnu.org/patch/?5909 as well.
4046 2021-10-05 Hugh McMaster <hugh.mcmaster@outlook.com>
4048 autogen.sh: Only copy submodules if building from a git branch.
4050 `autogen.sh` fails if building from a standard source tarball. Firstly, git
4051 expects to be called in a git repository, then `copy_submodule_files`
4052 blindly attempts to copy files.
4054 Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
4055 before compiling to regenerate build files.
4057 This patch ensures that various git commands are only called and 'dlg' files
4058 are only copied if `autogen.sh` is called from a git repository.
4060 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com>
4062 * include/freetype/internal/ftgloadr.h: Add missing header.
4064 Noticed by Jouk Jansen.
4066 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com>
4068 [pshinter] Additional clean-ups.
4070 * src/pshinter/pshalgo.h (psh_hint_table_find_strong_points): Streamline code.
4071 * src/pshinter/pshalgo.h (PSH_Glyph): Remove unused fields.
4073 2021-10-04 Alexei Podtelezhnikov <apodtele@gmail.com>
4075 [pshinter] More convenient direction definition.
4077 It is easier to check directions using flags than integer values.
4079 * src/pshinter/pshalgo.h (PSH_Dir): Redefine directions.
4080 (PSH_PointRec): Use them as an enum type.
4082 * src/pshinter/pshalgo.c (psh_compute_dir): Modify return type.
4083 (psh_glyph_init, psh_hint_table_find_strong_points,
4084 psh_glyph_find_blue_points): Update users.
4086 2021-10-04 Alexei Podtelezhnikov <apodtele@gmail.com>
4088 [pshinter] Remove unnecessary check.
4090 * src/pshinter/pshalgo.c (psh_hint_table_find_strong_points): Do not
4091 check if direction is defined before checking how.
4093 2021-10-02 AnuthaDev <anuthadev@gmail.com>
4095 CI: Hardcode meson version to fix build failure on windows
4097 2021-10-01 Alexei Podtelezhnikov <apodtele@gmail.com>
4099 Additional `FT_MSB` macro definitions.
4101 * include/freetype/internal/ftcalc.h [__DECC,_CRAYC]: Use builtins
4102 and intrinsics.
4104 2021-10-01 Alexei Podtelezhnikov <apodtele@gmail.com>
4106 * src/autofit/afhints.c (af_glyph_hints_reload): Decrease casting.
4108 2021-09-30 Alexei Podtelezhnikov <apodtele@gmail.com>
4110 * src/tools/apinames.c: Facilitate OpenVMS linker options.
4112 2021-09-29 Alexei Podtelezhnikov <apodtele@gmail.com>
4114 * src/winfonts/winfnt.c (FNT_Face_Init): Correct reallocation.
4116 2021-09-25 Alexei Podtelezhnikov <apodtele@gmail.com>
4118 [builds/unix] Do not use autoconf SIZEOF.
4120 * builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed.
4121 * builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update.
4123 After this commit, autoconf builds will fully rely on <limits.h>
4124 rather than falling back on it if AC_CHECK_SIZEOF failed for some
4125 reason. There is a risk that misconfigured cross-compilation might
4126 have wrong headers. Note that Meson and CMake builds always relied on
4127 <limits.h> for sizes and availability of integer types.
4129 2021-09-25 Alexei Podtelezhnikov <apodtele@gmail.com>
4131 Propagate sign when reading OFF3.
4133 Signed 24-bit values are extremely rare. FreeType only reads them in
4134 PFR fonts with bitmap strikes conditionally. They have not been seen
4135 in the known fonts. That is why this bug could never be discovered.
4136 `FT_FRAME_OFF3` propagates sign correctly.
4138 * include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE):
4139 Propagate sign into 32-bit value.
4140 (FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused.
4142 2021-09-25 Alexei Podtelezhnikov <apodtele@gmail.com>
4144 [bdf] Simplify comment collection or lack thereof.
4146 BDF comments are neither actually collected nor retrieved. There is
4147 no need to be fancy with delimiters.
4149 * src/bdf/bdflib.c (_add_bdf_comment): Delimit comments with zeros...
4150 (bdf_load_font): ...and do not null-terminate comments additionally.
4151 (_bdf_parse_glyphs): Check if comments are kept, which they are not.
4152 (_bdf_parse_start): Minor clean up.
4154 2021-09-24 Alexei Podtelezhnikov <apodtele@gmail.com>
4156 Use NULL for pointers only.
4158 * src/bdf/bdflib.c (*): Code changes.
4159 * include/freetype/freetype.h: Comments only.
4160 * src/cff/cffload.c, src/cff/cffobjs.c: Ditto.
4161 * src/winfonts/winfnt.c: Ditto.
4163 2021-09-23 Werner Lemberg <wl@gnu.org>
4165 Minor documentation fixes and improvements.
4167 2021-09-23 Alexei Podtelezhnikov <apodtele@gmail.com>
4169 Reference `fopen` in the docs.
4171 2021-09-23 Alexei Podtelezhnikov <apodtele@gmail.com>
4173 [bdf, pcf] Minor optimization.
4175 * src/pcf/pcfread.c (pcf_load_font): Do not call `FT_MulDiv` for a
4176 small job.
4177 * src/bdf/bdfdrivr.c (BDF_Face_Init): Ditto.
4178 * src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a comment.
4180 2021-09-22 Alexei Podtelezhnikov <apodtele@gmail.com>
4182 [base] Initialize stream memory earlier.
4184 With Windows memory management tracking heap, it is important to use
4185 it during the stream opening fallback. In Unix, the argument is
4186 unused, but it is better to set it correctly.
4188 * src/base/ftobjs.c (FT_Stream_New): Set memory before calling
4189 `FT_Stream_Open`.
4190 * builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open,
4191 ft_close_stream_by_free): Call `ft_alloc` and `ft_free` with proper
4192 memory argumment.
4194 2021-09-22 Alexei Podtelezhnikov <apodtele@gmail.com>
4196 [builds/windows] Revert back to `CreateFileA` only.
4198 Calling `CreateFileW` without making sure that the patname is really
4199 `wchar_t` is a bad idea and can lead to unpredictable overreads. For
4200 Windows CE, we impelemnt the missing API.
4202 Fixes #1098 and !76 again.
4204 * builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
4205 [_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.
4207 2021-09-21 Alexei Podtelezhnikov <apodtele@gmail.com>
4209 * src/bdf/bdflib.c (_bdf_parse_{start,glyphs}): Use appropriate scanner.
4211 2021-09-21 Alexei Podtelezhnikov <apodtele@gmail.com>
4213 Minor.
4215 2021-09-20 Alexei Podtelezhnikov <apodtele@gmail.com>
4217 * src/cff/cffdrivr.c (cff_ps_get_font_{info,extra}): Use FT_QNEW.
4219 2021-09-18 Alexei Podtelezhnikov <apodtele@gmail.com>
4221 [cache] Minor clean-ups.
4223 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Remove parantheses.
4224 * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
4225 (FTC_Cache_RemoveFaceID): Remove unnecessary variable.
4227 2021-09-17 Alexei Podtelezhnikov <apodtele@gmail.com>
4229 [builds/windows] Try both wide and narrow `CreateFile`
4231 Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
4232 filenames using alternative -A and -W API. We'll try them both
4233 when opening a file. This means that you should not worry about
4234 about conversions.
4236 Fixes #1098 and !76.
4238 * builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
4239 `CreateFile` in the case of failure.
4241 2021-09-17 Edwin Steiner <edwin.steiner@gmail.com>
4243 [cff] Explicitly set StandardEncoding or ExpertEncoding offsets.
4245 Fixes #1097.
4247 * src/cff/cffload.c (cff_encoding_load): Set special offset values.
4249 2021-09-16 Alexei Podtelezhnikov <apodtele@gmail.com>

4396 (ft_mem_debug_done): ... to here.
4398 2021-09-08 Alexei Podtelezhnikov <apodtele@gmail.com>
4400 Fortify memory debugging.
4402 These changes are neccessary to properly recover `memory->user` that
4403 holds the Windows heap handle now.
4405 * src/base/ftdbgmem.c (ft_mem_debug_init): Handle all table allocations,
4406 initializations, and sizing instead of...
4407 (ft_mem_table_new): ... this function removed.
4408 (ft_mem_debug_done): Better check for the active debugger and free the
4409 debugger table here instead of...

4493 [smooth] Reduce shift in multiply-shift optimization.
4495 * src/smooth/ftgrays.c (FT_UDIVPREP, FT_UDIV): Reduce shift.
4497 Smaller shifts that keep the division operands of FT_UDIVPREP within
4498 32 bits result in slightly faster divisions, which is noticeable in
4499 the overall performance. The loss of precision is tolerable until the
4500 divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
4501 PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
4502 that we refuse to render anyway.

4526 2021-08-27 Ben Wagner <bungeman@chromium.org>
4528 [smooth] Detect SSE2 with MSVC for x86
4530 MSVC does not set `__SSE2__`. Instead one must check whether `_M_IX86_FP` is
4531 defined and greater than or equal to 2.
4533 * src/smooth/ftgrays.c (FT_SSE2): New macro.
4534 Use it where appropriate.

4558 [truetype] Simplify `trick_names'.
4560 * src/truetype/ttobjs.c (tt_check_trickyness_family): For the case
4561 that the beginning part of a long tricky family name is already
4562 registered as another tricky family name, no need to double-check
4563 the longer one. Such long tricky family names are removed from
4564 the `trick_names'.
4566 2021-08-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

4577 [truetype] New function to skip the randomization tag.
4579 * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
4580 New function to skip the randomization tag in the names of the
4581 fonts embedded in a PDF. It is used by tt_check_trickyness_family(),
4582 to keep from mistaking "DLC" in the randomization tag as a
4583 tricky font name. See discussion in:
4585 https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html
4587 For technical detail about the randomization tag, please find

4615 [smooth] Clean up the null cell usage.
4617 Put the null cell at the end of the pool and store it explicitly so that
4618 we can use it as both the limit and the dumpster.
4620 * src/smooth/ftgrays.c (gray_TWorker): Store the last `cell_null` and
4621 remove unnecesary fields.
4622 (NULL_CELL_PTR, CELL_IS_NULL): Remove in favor of explicit `cell_null`.
4623 (gray_dump_cells, gray_set_cell, gray_sweep{,_direct}): Update callers.

4656 defined in <limits.h>.
4657 * include/freetype/config/integer-types.h: Check `long long` size and
4658 use it to typedef FT_Int64.
4660 2021-08-19 Dominik Röttsches <drott@chromium.org>
4662 [sfnt] Fix format expectation for `COLR` v1 ClipList
4664 * src/sfnt/ttcolr.c (tt_face_get_color_glyph_clipbox): Change ClipList
4665 format expectation to 1 instead of 0 to make it compliant with the
4666 latest spec.
4668 2021-08-19 Alexei Podtelezhnikov <apodtele@gmail.com>
4670 Readily use `long long` as a 64-bit type in C99 mode.
4672 * include/freetype/config/integer-types.h (FT_INT64):
4673 FT_CONFIG_OPTION_FORCE_INT64 is no longer required to use `long long`.
4675 2021-08-19 Alexei Podtelezhnikov <apodtele@gmail.com>
4677 Use FT_INT64 instead of FT_LONG64.
4679 * include/freetype/config/integer-types.h: Remove synonymous FT_LONG64.
4680 * include/freetype/internal/ftcalc.h: s/FT_LONG64/FT_INT64/.

4748 (FT_INTEGRATE): Use ADD_INT.
4750 2021-08-07 Dominik Röttsches <drott@chromium.org>
4752 [sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table.
4754 The optional 'COLR' v1 glyph-specific clip box helps upstream graphics
4755 libraries allocate a sufficiently large bitmap for a glyph without having to
4756 traverse the glyph graph for that. See
4758 https://github.com/googlefonts/colr-gradients-spec/issues/251
4760 for background on the introduction of this specification change.
4762 * include/freetype/ftcolor.h (FT_ClipBox): New structure.
4763 (FT_Get_Color_Glyph_ClipBox): New function declaration.
4765 * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_ClipBox_Func):
4766 New function type.

4769 * src/base/ftobjs.c (FT_Get_Color_Glyph_ClipBox): New function to link API
4770 with SFNT implementation.
4772 * src/sfnt/sfdriver.c (sfnt_interface): Updated.

4788 (gray_render_conic) [BEZIER_USE_DDA]: Use it.
4790 2021-08-02 Werner Lemberg <wl@gnu.org>
4792 * meson.build: Fix zlib support.
4794 This commit synchronizes zlib support with both autotools and cmake: If no
4795 external zlib is found (or intentionally disabled on the command line), use
4796 the internal zlib by undefining `FT_CONFIG_OPTION_SYSTEM_ZLIB` without
4797 modifying `FT_CONFIG_OPTION_USE_ZLIB`.
4799 Also improve summary output.
4801 Problem reported by Moazin.
4803 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in>
4805 [sdf] Fix out-of-range-access.

4810 Fixes issue #1077.
4812 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in>
4814 Fix invalid memory access in `bsdf` rasterizer.
4816 Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not
4817 set. In some cases the bitmap buffer is freed but still points to a valid
4818 address; to handle those cases check the flag before accessing the memory.
4820 * src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case.
4821 Also, return an error message if the bitmap's rows/pitch is invalid,
4822 otherwise `slot->buffer` might be assigned to some invalid memory location.
4823 (ft_sdf_render): Same as above.
4824 Plus, move the outline back to original state after rasterization and not if
4825 any error occurs.
4827 2021-07-29 Heiko Becker <heirecka@exherbo.org>
4829 * meson.build: Honor `--includedir` instead of hard-coding 'include'.

4837 [sfnt] 'COLR' v1 PaintSweepGradient spec update
4839 * src/sfnt/ttcolr.c (read_paint): PaintSweepGradient follows other
4840 spec changes and now has the angles specified as F2DOT14, reflect
4841 that in the implementation.
4842 * include/freetype/ftcolor.h (FT_PaintSweepGradient): Update
4843 documentation.
4845 2021-07-29 Dominik Röttsches <drott@chromium.org>
4847 [sfnt] Retrieve affine matrix from offset in 'COLR' v1 parsing.
4849 * src/sfnt/ttcolr.c (read_paint): Implement spec change where

4851 being placed inline in the PaintTransform table.
4853 2021-07-29 Dominik Röttsches <drott@chromium.org>
4855 [sfnt] 'COLR' v1 PaintSkew related spec updates
4857 * src/sfnt/ttcolr.c (read_paint): Implement spec changes around
4858 PaintSkew, PaintSkewAroundCenter. Update parsing to read shorter
4859 values as changed in the spec.

4862 2021-07-29 Dominik Röttsches <drott@chromium.org>
4864 [sfnt] PaintRotate/PaintRotateAroundCenter spec updates
4866 * src/sfnt/ttcolr.c (read_paint): Implement spec change where
4867 PaintRotate and PaintRotateAroundCenter were split for a more
4868 compact format definition. Update parsing to read shorter values
4869 as changed in the spec.
4870 * include/freetype/ftcolor.h (FT_PaintRotate): Update documentation.
4872 2021-07-29 Dominik Röttsches <drott@chromium.org>
4874 [sfnt] 'COLR' v1 PaintTranslate and PaintScale precision
4876 * src/sfnt/ttcolr.c (read_paint): Implement spec changes in

4886 ChangeLog housekeeping.
4888 Archive old `ChangeLog` file.
4890 We no longer write ChangeLog entries manually; instead, the file will be
4891 created from commit messages (which should be formatted in GNU's ChangeLog
4892 style) by a call to

4935 [autofit] Split `afwrtsys.h`.
4937 The header file `afwrtsys.h` has two distinct functions: to include the
4938 required writing system headers and also to generate code for each writing
4939 system. At each current use site only one or the other is used, with
4940 various macro trickery selecting one or the other. Split this header into
4941 `afws-decl.h` for the required writing system declarations and `afws-iter.h`
4942 for iterating over the writing systems to generate code.
4944 The motivation for this change is that the Visual C++ compiler treats the
4945 standard include guard idiom like `#pragma once` 'if no non-comment code or
4946 preprocessor directive comes before or after the standard form of the
4947 idiom'. It appears to check this after macro expansion, so if
4948 `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and
4949 looks like the standard include guard idiom which is treated like `#pragma
4950 once`, so subsequent inclusion of `afwrtsys.h` is elided.
4952 Fixes #1075.
4954 * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h
4955 (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated.
4957 * src/autofit/afwrtsys.h: Split into...
4958 * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.
