[truetype] Quietly reject out-of-spec `hdmx` tables.
The `hdmx` table is optional and can be safely rejected without
an error if it does not follow specifications. The record size
must be equal to the number of glyphs + 2 + 32-bit padding.
* src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check
the record size and improve tracing.
2021-11-23 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[truetype] Partly revert 5b626281.
Fixes #1118.
* src/truetype/ttpload.c (tt_face_load_hdmx): Do not assume that
`record_size` is rounded even though the records are padded.
2021-11-23 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>

Define.
2021-11-20 Werner Lemberg <wl%gnu.org@localhost>
Avoid undefined left-shifts.
We really have to use double casts to avoid issues with C's and C++'s
signedness propagation rules in implicit casts.

(FT_STATIC_BYTE_CAST): ... this.
2021-11-18 Werner Lemberg <wl%gnu.org@localhost>
Provide C++ versions for public macros with casts.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.
* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,
FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`.
Correctly handle negative 'signed char' input.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto.
* include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use
`FT_REINTERPRET_CAST`.
* src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro.
[!STANDALONE]: Include `FT_CONFIG_CONFIG_H`.
Fixes #1116.

s/shortDeltaCount/wordDeltaCount/ (as done in the specification, too).
Recognize new format and reject it for now.
2021-11-16 Werner Lemberg <wl%gnu.org@localhost>
[truetype] Updates for the forthcoming OpenType 1.9 standard (1/2).
This is in preparation for implementing `DeltaSetIndexMap` format 1, which
is used by `COLR` v1 tables, and which allows 32bit indices.
https://docs.microsoft.com/en-us/typography/opentype/otspec190/delta/otvarcommonformats_delta.html
* src/truetype/ttgxvar.h (GX_DeltaSetIdxMapRec): Change type of `mapCount`

2021-11-13 Dominik Röttsches <drott%chromium.org@localhost>
[sfnt] Avoid undefined shifts in `COLR` v1 paint parsing
* src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Tighten shift
behavior by using multiplication, mostly using macros from ftcalc.h.
Fixes: https://bugs.chromium.org/p/chromium/issues/detail?id=1269168
2021-11-13 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>

from metarutaiga.
* include/freetype/internal/ftcalc.h [_MSC_VER] (FT_MSB): Updated.
2021-11-09 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[build/windows] Remove logging from default debug configurations.
DLG is rather costly for performance and should be used judiciously.
This removes it from the default configurations but gives an example
how to enable it using the `UserDefines` property.
* builds/windows/vc2010/freetype.vcxproj: Hide FT_DEBUG_LOGGING.
2021-11-08 Werner Lemberg <wl%gnu.org@localhost>

2021-11-08 Werner Lemberg <wl%gnu.org@localhost>
[sfnt] Reduce footprint if WOFF and WOFF2 support is not needed.
Based on a patch from metarutaiga (MR !106). The gist of this commit is
that it doesn't make sense to support WOFF without compression (which would
be only possible in WOFF 1.0 anyway).
* src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with
`FT_CONFIG_OPTION_USE_ZLIB` block.
Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block.
* src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with
`FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code.
* src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c,
src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks,
not parts of the code.
Fixes #1111.
2021-11-08 Werner Lemberg <wl%gnu.org@localhost>
[truetype] Make trickyness checks depend on TT_USE_BYTECODE_INTERPRETER.
Based on a patch from metarutaiga (MR !106).
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag,
tt_check_trickyness_family, tt_synth_sfnt_checksum, tt_get_sfnt_checksum,
tt_check_trickyness_sfnt_ids, tt_check_trickyness): Put functions into a
`TT_USE_BYTECODE_INTERPRETER` block.
(tt_face_init): Put trickyness checks into a `TT_USE_BYTECODE_INTERPRETER`
block.
Fixes #1111.
2021-11-08 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
* src/sfnt/ttload.c (tt_face_load_gasp): Fix a type mismatch warning.
2021-11-07 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[dlg] Define DLG_STATIC explicitly.
DLG_STATIC is intended to disable Windows DLL linking attributes.
It does not hurt to define it explicitly when we wrap DLG code.
This fixes tons of LNK4286 and C4273 warnings from MSVC if we
forget to define DLG_STATIC as a compiler option.
* builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option.
* src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC.
* include/freetype/internal/ftdebug.h [FT_DEBUG_LOGGING]: Ditto.
2021-11-07 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[dlg] Lighten up the inclusions.
The DLG wrapper needs to know if FT_DEBUG_LOGGING is defined in
`ftoption.h`. It does not need entire FreeType.
* src/dlg/dlgwrap.c: Include FT_CONFIG_OPTIONS_H directly.
2021-11-07 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[truetype] Avoid some memory zeroing in variations.
* src/truetype/ttgxvar.c (ft_var_readpackeddeltas, ft_var_load_avar,
ft_var_load_item_variation_store, ft_var_load_gvar): Use FT_QNEW_ARRAY
if memory immediately initialized or discarded otherwise.
2021-11-05 Jany Belluz <jany.belluz%daltonmaag.com@localhost>
[truetype] Fix handling of packed deltas in Variation Fonts.
* src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of
bytes used to encode the deltas to be higher than the number of encoded
values. The specification allows a very compact encoding; for example, a
list of 200 zeros can be encoded with just a couple of bytes.
We now count the consumed bytes to make sure to not read more than expected.
2021-11-04 Jany Belluz <jany.belluz%daltonmaag.com@localhost>
[truetype] Fix CVAR handling of tuples for all points.
* src/truetype/ttgxvar (tt_face_vary_cvt): Function
`ft_var_readpackedpoints`, when it returns `ALL_POINTS`, also sets
`point_count` to value 0. However, the CVAR code was incorrectly expecting
that `point_count` would be set to match the length of the CVT table.
2021-11-04 Jany Belluz <jany.belluz%daltonmaag.com@localhost>
* src/truetype/ttgxvar.c: Fix typos in macros that guard CVAR code.
2021-11-04 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
* docs/INSTALL: Mention Meson and MSBuild more prominently.
2021-11-03 Gabor Kertesz <gabor.kertesz%linaro.org@localhost>
[libpng] Update Meson wrap for win-arm64
1.6.37-5 released patches for win-arm64 to successfully build
libpng with Meson:
https://github.com/mesonbuild/wrapdb/pull/205
https://github.com/mesonbuild/wrapdb/pull/216
Updated by the following command:

Tested on win-arm64 and x64.
2021-11-03 Dominik Röttsches <drott%chromium.org@localhost>
[sfnt] Clarify `COLR` v1 FT_Paint* format representations
* include/freetype/ftcolor.h (FT_PaintLinearGradient,
FT_PaintRadialGradient, FT_PaintSweepGradient, FT_PaintTransform,
FT_PaintTranslate, FT_PaintScale, FT_PaintRotate, FT_PaintSkew): Clarify
16.16 fixed point representation of struct fields.
* src/sfnt/ttcolr.c (read_paint): Shift coordinates for
FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintSweepGradient
accordingly.

[builds/windows] Separate MSVC linker and librarian.
MSVC uses LIB for static and LINK for dynamic libraries. They are
related but the former has much smaller set of options.
* builds/windows/vc2010/freetype.vcxproj: Updated.
2021-10-29 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[builds/windows] Revise MSVC linking optimizations.
* builds/windows/vc2010/freetype.vcxproj: Optimize DLL linking only.

2021-10-26 Ben Wagner <bungeman%chromium.org@localhost>
[mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.
In the future it may be best to keep track of when these are actually
initialized and error if they are not.
* src/type1/t1load.c (t1_allocate_blend): Zero initiailize.
2021-10-26 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[builds/windows] Add MSVC linker optimazations.
We continue to build static libraries with statically linked C run-
time and add options to optimize references.
* builds/windows/vc2010/freetype.vcxproj: Sort entries, add options.
2021-10-23 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
* builds/windows/vc2010/freetype.vcxproj: Use MachineARM64.
2021-10-22 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>

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

https://bugs.chromium.org/p/chromium/issues/detail?id=1261762
* src/type1/t1load.c (t1_allocate_blend): Remove early allocation and
initialization.
(parse_blend_design_positions, parse_weight_vector): Parse into local
and assign to blend if valid.
(T1_Open_Face): Check that if a blend exists that it has the weight
vector and design positions.
2021-10-21 Ben Wagner <bungeman%chromium.org@localhost>
[cff] Commit vstore data and regions on allocation.
The vstore->regionCount and vstore->dataCount were read directly
from the data. However, vstore->varRegionList and vstore->varData
would still contain uninitialized entries with uninitialized
pointers in the event of an error, leading to issues when attempting
to clean up.
Reportd as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104
* src/cff/cffload.c (cff_vstore_load): Read the region and data counts
into locals and update the vstore counts immediately after each entry
becomes free-able.
2021-10-20 Ben Wagner <bungeman%chromium.org@localhost>
[sfnt] Delay setting gasp ranges and count until computed.
Previously, the gasp.numRanges was set and gasp.gaspRanges was
allocated and assigned before a possible early exit if the frame could
not be entered. It is also possible that the gaspRanges allocation
could fail but the numRanges still be set to non-zero. In such cases
an error would be returned, but the face would have a gasp in an
inconsistent state which may still be accessed.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1261450
* src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges
and gasp.gaspRanges until after the ranges are initialized.
2021-10-20 Ben Wagner <bungeman%chromium.org@localhost>
[sfnt] Delay setting names and langTags until computed.
Previously, the table->names and table->langTags fields were created
pointing to uninitialized memory and an early exit could happen if the
frame could not be entered. The caller would then be unable to properly
dispose of the memory as the string fields had not been initialized.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1261343
* src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags

When a different hinting mode from the current is selected, the `prep` table
must be re-executed with the new mode. After this happens the context must
be re-loaded in preparation for the glyph program to be run.
Fixes #1104.

meson.build (gen_docs): Use `current_source_dir` instead of `source_root`.
These two are not equal when FreeType is used as a subproject, such as in
`freetype-demos`. In that case, `source_root` points at the root project,
causing the docs build to fail.

2021-10-05 Hugh McMaster <hugh.mcmaster%outlook.com@localhost>
autogen.sh: Only copy submodules if building from a git branch.
`autogen.sh` fails if building from a standard source tarball. Firstly, git
expects to be called in a git repository, then `copy_submodule_files`
blindly attempts to copy files.
Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
before compiling to regenerate build files.
This patch ensures that various git commands are only called and 'dlg' files
are only copied if `autogen.sh` is called from a git repository.

* src/pshinter/pshalgo.c (psh_compute_dir): Modify return type.
(psh_glyph_init, psh_hint_table_find_strong_points,

[builds/unix] Do not use autoconf SIZEOF.
* builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed.
* builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update.
After this commit, autoconf builds will fully rely on <limits.h>
rather than falling back on it if AC_CHECK_SIZEOF failed for some
reason. There is a risk that misconfigured cross-compilation might
have wrong headers. Note that Meson and CMake builds always relied on
<limits.h> for sizes and availability of integer types.
2021-09-25 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
Propagate sign when reading OFF3.
Signed 24-bit values are extremely rare. FreeType only reads them in
PFR fonts with bitmap strikes conditionally. They have not been seen
in the known fonts. That is why this bug could never be discovered.
`FT_FRAME_OFF3` propagates sign correctly.
* include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE):
Propagate sign into 32-bit value.
(FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused.
2021-09-25 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[bdf] Simplify comment collection or lack thereof.
BDF comments are neither actually collected nor retrieved. There is
no need to be fancy with delimiters.
* src/bdf/bdflib.c (_add_bdf_comment): Delimit comments with zeros...
(bdf_load_font): ...and do not null-terminate comments additionally.
(_bdf_parse_glyphs): Check if comments are kept, which they are not.
(_bdf_parse_start): Minor clean up.
2021-09-24 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>

* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a comment.
2021-09-22 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[base] Initialize stream memory earlier.
With Windows memory management tracking heap, it is important to use
it during the stream opening fallback. In Unix, the argument is
unused, but it is better to set it correctly.
* src/base/ftobjs.c (FT_Stream_New): Set memory before calling
`FT_Stream_Open`.
* builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open,
ft_close_stream_by_free): Call `ft_alloc` and `ft_free` with proper
memory argumment.
2021-09-22 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[builds/windows] Revert back to `CreateFileA` only.
Calling `CreateFileW` without making sure that the patname is really
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
Windows CE, we impelemnt the missing API.
Fixes #1098 and !76 again.
* builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
[_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.
2021-09-21 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>

2021-09-17 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
[builds/windows] Try both wide and narrow `CreateFile`
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
filenames using alternative -A and -W API. We'll try them both
when opening a file. This means that you should not worry about
about conversions.
Fixes #1098 and !76.
* builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
`CreateFile` in the case of failure.
2021-09-17 Edwin Steiner <edwin.steiner%gmail.com@localhost>

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

[truetype] New function to skip the randomization tag.
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
New function to skip the randomization tag in the names of the

[autofit] Split `afwrtsys.h`.
The header file `afwrtsys.h` has two distinct functions: to include the
required writing system headers and also to generate code for each writing
system. At each current use site only one or the other is used, with
various macro trickery selecting one or the other. Split this header into
`afws-decl.h` for the required writing system declarations and `afws-iter.h`
for iterating over the writing systems to generate code.
The motivation for this change is that the Visual C++ compiler treats the
standard include guard idiom like `#pragma once` 'if no non-comment code or
preprocessor directive comes before or after the standard form of the
idiom'. It appears to check this after macro expansion, so if
`WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and
looks like the standard include guard idiom which is treated like `#pragma
once`, so subsequent inclusion of `afwrtsys.h` is elided.
Fixes #1075.

* src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined.
The code assumed that if `__SSE2__` is defined, then 64-bit integer
types are available. This is not the case apparently for certain
multilib compiler targets like 'x86_32.x86' used by Gentoo.
This patch fixes the issue by disabling the special code path when
64-bit integer types are not available.
Fixes #1071.

[tests] Allow arbitrary build directories.
* tests/issue-1063/main.c (main): I am building with a build

[smooth] Minor fixes.
* src/smooth/ftgrays.c (gray_render_conic): Move variable and
structure declarations to beginning of function. Inspite of C99
compliance we still do this for the sake of backward compatibility.
This also avoids a shadowing declaration of `count`.
(gray_convert_glyph_inner): Fix typo.

* src/smooth/ftgrays.c: Guard inclusion of `emmintrin.h`.
Guard inclusion of `emmintrin.h` with `#ifdef __SSE2__`. The gcc
version of this header, `xmmintrin.h`, and `mmintrin.h` check that
the appropriate defines are set before defining anything (are
internally guarded). However, the clang versions of these includes
are not internally guarded. As a result of this, externally guard
the inclusion of these headers.

[smooth] Implement Bézier quadratic arc flattening with DDA.
Benchmarking shows that this provides a very slighty performance
boost when rendering fonts with lots of quadratic Bézier arcs,
compared to the recursive arc splitting, but only when SSE2 is

[smooth] Minor speedup to smooth rasterizer.
This speeds up the smooth rasterizer by avoiding conditional
branches in the hot path.
- Define a fixed 'null cell', which will be pointed to whenever the
current cell is outside of the current target region. This avoids
a `ras.cell != NULL` check in the `FT_INTEGRATE` macro.
- Also use the null cell as a sentinel at the end of all `ycells`
linked-lists, by setting its x coordinate to `INT_MAX`. This
avoids a `if (!cell)` check in `gray_set_cell` as well.
- Slightly change the worker struct fields to perform a little less
operations during rendering.
Example results (on a 2013 Corei5-3337U CPU)

Support architectures where `long` is smaller than pointers.
I am currently trying to compile FreeType for CHERI-extended ISAs
(CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings
from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI
Clang compiler, not using `uinptr_t` for casts between integers an
pointers results in the following `-Werror` build failures:
```
In file included from .../src/truetype/truetype.c:22:
.../src/truetype/ttgload.c:1925:22: error:
cast from provenance-free integer type to pointer type will
give pointer that can not be dereferenced
[-Werror,-Wcheri-capability-misuse]
node->data = FT_UINT_TO_POINTER( glyph_index );
^
.../include/freetype/internal/compiler-macros.h:79:34: note:
expanded from macro 'FT_UINT_TO_POINTER'
```
* include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER):
The ISO C standard compliant fix for this would be to use
`uintptr_t` from `stdint.h`, but I am not sure if this is supported
by the minimum compiler version. Therefore, use the
compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and
Clang since about 3.0) before checking for `_WIN64` and falling back
to `unsigned long`.
2021-07-13 Oleg Oshmyan <chortos%inbox.lv@localhost>
[base] Fix `FT_Open_Face`'s handling of user-supplied streams.
This was already true (though undocumented) most of the time, but
not if `FT_NEW` inside `FT_Stream_New` failed or if the
`FT_OPEN_XXX` flags were bad.
Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the
user-supplied stream unchanged, and in case of any subsequent error
in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`.
Up to now, however, `FT_Stream_New` allocates a new stream even if
it is already given one by the user. If this allocation fails, the
user-supplied stream is not returned to `FT_Open_Face` and never
closed. Moreover, the user cannot detect this situation: all they
see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that
can also happen after a different allocation fails within the main
body of `FT_Open_Face`, when the user's stream has already been
closed by `FT_Open_Face`. It is plausible that the user stream's
`close` method frees memory allocated for the stream object itself,
so the user cannot defensively free it upon `FT_Open_Face` failure
lest it ends up doubly freed. All in all, this ends up leaking the
memory/resources used by user's stream.
Furthermore, `FT_Stream_New` simply returns an error if the
`FT_OPEN_XXX` flags are unsupported, which can mean either an
invalid combination of flags or a perfectly innocent
`FT_OPEN_STREAM` on a FreeType build that lacks stream support.
With this patch, the user-supplied stream is closed even in these
cases, so the user can be sure that if `FT_Open_Face` failed, the
stream is definitely closed.
* src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer
unnecessarily.
Move error-handling code to make the control flow more obvious.
Close user-supplied stream if the flags are unsupported.
`FT_Stream_Open` always sets `pathname.pointer`, so remove the
redundant (re)assignment. None of the `FT_Stream_Open...` functions
uses `stream->memory`, so keep just one assignment at the end,
shared among all possible control flow paths.
('Unsupported flags' that may need a stream closure can be either an
invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean
`FT_OPEN_STREAM` flag on a FreeType build that lacks stream
support.)
2021-07-13 Oleg Oshmyan <chortos%inbox.lv@localhost>
[base] Reject combinations of incompatible `FT_OPEN_XXX` flags.
The three modes are mutually exclusive, and the documentation of the
`FT_OPEN_XXX` constants notes this. However, there was no check to
validate this in the code, and the documentation on `FT_Open_Args`
claimed that the corresponding bits were checked in a well-defined
order, implying it was valid (if useless) to specify more than one.
Ironically, this documented order did not agree with the actual
code, so it could not be relied upon; hopefully, nobody did this and
nobody will be hurt by the new validation.
Even if multiple mode bits were allowed, they could cause memory
leaks: if both `FT_OPEN_STREAM` and `stream` are set along with
either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New`
allocated a new stream but `FT_Open_Face` marked it as an 'external'
stream, so the stream object was never released.
* src/base/ftobjs.c (FT_Stream_New): Reject incompatible
`FT_OPEN_XXX` flags.
2021-07-12 Alex Richardson <Alexander.Richardson%cl.cam.ac.uk@localhost>
* meson.build: Fix build for other UNIX systems (e.g., FreeBSD).
Without this change the build of `unix/ftsystem.c` fails because the
`ftconfig.h` header that defines macros such as `HAVE_UNISTD_H` and
`HAVE_FCNTL_H` is only being generated for Linux, macOS, and Cygwin
systems:
```
.../builds/unix/ftsystem.c:258:32: error:
use of undeclared identifier 'O_RDONLY'
file = open( filepathname, O_RDONLY );
```
Instead of hardcoding a list of operating systems for this check,
update the logic that decides whether to build the file and set a
boolean flag that can be checked instead.

* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`.
It is undefined behavior to pass `NULL` to `memcpy`. `coords' is
passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design`
explictly call `tt_set_mm_blend` with `coords` as `NULL`. In
addition, `TT_Set_MM_Blend` has a similar possible issue.

2021-06-30 Dominik Röttsches <drott%chromium.org@localhost>
[sfnt] Handle fonts without layer list in 'COLR' v1.
'COLR' v1 fonts do not necessarily need to have a layer list; for
this reason, 'fontTools' recently started generating fonts in a way
that drops the layer list if there are no layers in it. This
results in the layer list offset becoming zero, which FreeType
treated as an invalid table. Fix that and handle the case for layer
list offset being 0. This slightly changes how we need to calculate
the starting offset for paints.
* src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list
offset being zero without outright rejecting table.

2021-06-28 Dominik Röttsches <drott%chromium.org@localhost>
[sfnt] Improve paint limit checks
Paint tables can appear before the `base_glyphs_v1` offset if the
font is produced with the layer list before the base glyph list. In
this case paint tables can occur after the layer list but before the
base glyph list. Checks in the 'COLR' v1 code were rejecting fonts
with this layout. Improve these checks by calculating a minimum
offset after which paint tables can occur and use that in safety
checks.
* src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare
`paint_start_v1` and calculate that as the minimum of the end of
layer list and base glyph list.
(get_child_table_pointer, read_paint, tt_face_get_paint_layers):
Use that in safety checks.

[raster] Adjust sub-band bisecting limits.
We can bisect a band until it is just a single scan line. This might
be slow and cause time-outs but if we need to impose limits it should
be elsewhere.

* src/raster/ftraster.c (Render_Single_Pass): Remove dead code.
2021-06-25 Werner Lemberg <wl%gnu.org@localhost>
[base] Add trace level to logging output.
Some practical debugging work has shown that displaying level X of
an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be
very helpful to find out which trace level should be selected. As
an example, we now get output like
```
[ttobjs:2] TTF driver
[ttobjs:2] SFNT driver
[sfobjs:2] not a font using the SFNT container format
[t1objs:2] Type 1 driver
[stream:7] FT_Stream_EnterFrame: 14 bytes
```
* include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro.

[smooth, raster] Fix up and align error codes.
FT_Render_Glyph picked up FAILURE or 1 returned from the raster
function, which became a confusing error code. Instead, return
Raster_Overflow in the unlikely event that banding does not help or
another meaningful error.
* src/smooth/ftgrays.c (gray_convert_glyph_inner, gray_convert_glyph):
Use Raster_Overflow when the rendering pool is exhausted and return it

successful, but -1 is still returned by the function. The fix is to
set `error` to 0 appropriately.

[sdf] Use 8 bits for final SDF output instead of 16bits.
Since 8-bits is enough to represent SDF data we no longer require
16-bits for this purpose. Also, we now normalize the output data

3.5 format with a spread of 1 we basically only use the starting
5-bits. By normalizing we can use the entire 8-bit range.

[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`.
While a function pointer may be cast to another function pointer
type, it is required to cast the function pointer back to the
original function pointer type before calling it. If a parameter is
a pointer the exact pointer type is required. Using a pointer to a
different underlying type is technically undefined behavior. The
wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took
`FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so
when gzip calls these callbacks through `alloc_func` or `free_func`
it invokes undefined behavior. On most platforms this works out as
expected, but newer undefined behavior detectors and targets like
wasm can detect this and will produce an error.
* src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures
to exactly match `alloc_func` and `free_func`, respectively.
Internally, cast the `void*` opaque pointer to `FT_Memory`.

[base] Complete `ft_glyphslot_clear`.
* src/base/ftobjs.c (ft_glyphslot_clear): This function is intended
to reset all the values of a glyph slot. However, it was not
resetting the values of the advances and `glyph_index`. Reset the
advances and `glyph_index` to zero.
2021-04-02 Ben Wagner <bungeman%chromium.org@localhost>
[truetype] Prevent glyph program state from persisting.
`FDEF` instructions are specified as allowed only in 'prep' or
'fpgm'. FreeType has attempted to prevent their use in the glyph
program, but they were still allowed in glyph programs if defined in
a function defined in 'prep' or 'fpgm' and called from the glyph
program.
Similarly, `IDEF` instructions are specified not to be able to
modify any existing instruction. FreeType has attempted to prevent
their use in the glyph program, but they can still be used like
`FDEF`.
This change stores the initial bytecode range type and disallows the
use of `FDEF` and `IDEF` while running the glyph program.
Most other state is copied from the `TT_Size` into the execution
context. However, it is possible for a glyph program to use `WS` to
write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to
write to the control value table.
Allowing any change to the global state from the glyph program is
problematic as the outlines of any given glyph may change based on
the order the glyphs are loaded or even how many times they are
loaded. There exist fonts that write to the storage area or the
control value table in the glyph program, so their use should not be
an error.
Possible solutions to using these in the glyph program are
* ignore the writes;
* value-level copy on write, discard modified values when finished;
* array-level copy on write, discard the copy when finished;
* array-level copy up-front.
Ignoring the writes may break otherwise good uses. A full copy
up-front was implemented, but was quite heavy as even well behaved
fonts required a full copy and the memory management that goes along
with it. Value-level copy on write could use less memory but
requires a great deal more record keeping and complexity. This
change implements array-level copy on write. If any attempt is made
to write to the control value table or the storage area when the
initial bytecode range was in a glyph program, the relevant array
will be copied to a designated storage area and the copy used for
the rest of the glyph program's execution.

[sfnt] Fix memory leak in png loading.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1182552
Memory is allocated and the pointer assigned to `rows` inside a
'setjmp' scope. This memory must be freed outside the 'setjmp'
scope after a 'longjmp'. Since `rows` is a local and modified
inside the 'setjmp' scope it must be marked volatile or it will have
an indeterminate value after the 'longjmp'.

2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build: s/freetype2_dep/freetype_dep/.
Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep`
variable name to use FreeType as subproject because that was the
variable name in Centricular's Meson port of FreeType. While they
should stop hardcoding that variable name, it does not cost us
anything to keep using that name to ease transition.
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
[meson] Fix handling of HarfBuzz library.
* meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by
default.
Otherwise it causes a dependency cycle:
cairo => fontconfig => freetype2 => harfbuzz => cairo
Meson will still fall back to HarfBuzz subprojects if the `harfbuzz`
option is set to `enabled` instead of `auto` and a
`subprojects/harfbuzz.wrap` file is present. In that case it is the
responsibility of the main project to set the proper options on each
subproject to break the dependency cycle.
Fixes: #1028.

[meson] Fix dependency lookup and generate `ftconfig.h`.
- zlib: If not found on the system, meson can build it as a
subproject. We thus never use the (outdated) zlib support that
comes with FreeType. Doing so has the additional advantage that
the zlib code can be shared with other projects like GLib if both
are subprojects of an application.
- harfbuzz: Build as a subproject if not found on the system.
- 'QUESTION: What if the compiler doesn't support `-D` but uses `/D`
instead as on Windows?' Answer: Meson translate arguments for us.
- visibility: Replace self-made code with meson-specific solution.
* meson.build (ft2_defines): Rewrite logic to set and handle it.
(process_header_command): New variable, previously called
`ftoption_command`.
(ftoption_command, ftconfig_command): New variables.
(zlib_option): Removed.
(zlib_dep): New variable.
(ft2_deps): Updated.
(harfbuzz_dep): Updated.
(ftconfig_h_in, ftconfig_h): New variables.
(ft2_sources): Updated.
(ft2_lib): Updated, handle visibility.
(summary): Updted.
* meson_options.txt (zlib): Updated.
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build: Fix resource compilation on Windows.
This is copied from GStreamer's meson port of FreeType.
(ft2_sources): Add both debug and resource file (the latter for
Windows only).
(ft2_debug_src): Removed.
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/.
(freetype2_dep): Use it.
`ft2_libtool_version` would be the shared library version, not the
one we should use in file `freetype2.pc`.
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build: Use `meson.override_dependency`.
This is a new meson mechanism to avoid other projects to hard-code
the `freetype2_dep` variable name in their build definition. It
also ensures that meson does not mix system and subproject versions
of FreeType inside of the same project.
Also remove outdated TODO because `declare_dependency` was already
there.
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build (bzip2_dep): Simplify.
We remove `static:false` from `find_library('bz2')`.
I don't know whether the previous code was a workaround for an old
meson bug, but at least with version >=0.55.0 (which FreeType uses)
it picks the shared library when both are available.
File `freetype2.pc` still contains the full path to file `libbz2.so`
instead of `-lbz2` – that we need to do this is a meson bug even
present in the current version (0.57.0).
2021-02-09 Xavier Claessens <xavier.claessens%collabora.com@localhost>
* meson.build: Set project version.
2021-02-04 Werner Lemberg <wl%gnu.org@localhost>
[base] Fix Netpbm tracing message.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Don't emit Netpbm
warning if there is nothing to output.
2021-02-04 Werner Lemberg <wl%gnu.org@localhost>
* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.

modify `ftexport.sym` conditionally.
Problem reported by Alexei.
* src/base/ftdebug.c: Include `ftlogging.h`.
(FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler,

* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are

2020-08-16 Anuj Verma <anujv%iitbhilai.ac.in@localhost>
[sdf] Add files for new 'sdf' module.
Here is a breakdown of what the files will contain.
* src/sdf/ftsdfrend.c, src/sdf/ftsdfrend.h: The 'sdf' and 'bsdf'
renderers.
* src/sdf/ftsdf.c, src/sdf/ftsdf.h: The rasterizer for the 'sdf'
renderer.
* src/sdf/ftbsdf.c, src/sdf/ftbsdf.h: The rasterizer for the 'bsdf'
renderer.
* src/sdf/ftsdfcommon.h: Commmon properties and functions for both
rasterizers.
* src/sdf/ftsdferrs.h: Common error defines.
* src/sdf/sdf.c: For building a single object of the entire module.
2020-08-16 Anuj Verma <anujv%iitbhilai.ac.in@localhost>
[base] Allow renderers of different formats.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the
glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming
'bsdf' renderer will require bitmaps for processing.
* src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove
renderer's glyph format check before adding and removing them. The
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.
2020-08-16 Anuj Verma <anujv%iitbhilai.ac.in@localhost>
Add data types required for the forthcoming 'sdf' module.
* include/freetype/freetype.h (FT_Render_Mode): Add new render mode
`FT_RENDER_MODE_SDF`, which will be used to generate SDF.
* include/freetype/ftimage.h (FT_Pixel_Mode): Add new pixel mode
`FT_PIXEL_MODE_GRAY16`, which will be the output of the 'sdf'
module.
(FT_RASTER_FLAG_SDF): New raster flag to be used internally by the
'sdf' module.
* include/freetype/fttypes.h (FT_F6Dot10): New data type.
2020-08-16 Anuj Verma <anujv%iitbhilai.ac.in@localhost>
[base] Allow renderers of different formats.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the
glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming
'bsdf' renderer will require bitmaps for processing.
* src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove
renderer's glyph format check before adding and removing them. The
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.
2020-12-23 Werner Lemberg <wl%gnu.org@localhost>
* builds/windows/detect.mk (COPY): Make it work with `shell`.
Without this patch, we get the error
builds/toplevel.mk:127: *** missing separator. Stop.
Reported by Anuj, with a solution from Alexei.
2020-12-23 Ignacio Casal Quinteiro <qignacio%amazon.com@localhost>
* meson.build (ft2_defines): Fix builds on Windows.
2020-12-18 Tatsuyuki Ishi <ishitatsuyuki%gmail.com@localhost>
[autofit] Fix double division in stem darkening.
The old code used to divide the darkening amount by em_ratio twice,
leading to unnecessarily bold stems on certain fonts with higher
units per em (e.g. Inter). This patch fixes it.
The return value of af_loader_compute_darkening was also changed to
use 16.16 fixed point to get rid of a redundant truncation operation.
This should slightly improve the precision, although it's still
bottlenecked by the emboldening function, which uses 26.6 fixed point.
* src/autofit/afloader.[ch]
(af_loader_compute_darkening): Return FT_Fixed.
(af_loader_embolden_glyph_in_slot): Revise calculations.
2020-12-17 Alexei Podtelezhnikov <apodtele%gmail.com@localhost>
* include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): New public macro.
The driver name is needed for `FT_Property_Set' and `FT_Property_Get'.
2020-12-16 Chris Liddell <chris.liddell%artifex.com@localhost>
[truetype] Fix incremental metrics (#59503).
* src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph):
Previously, the code would populate the phantom points before
calling the `get_glyph_metrics` callback. For formats like PCL XL
format 1, class 2 downloaded fonts (where metrics are removed from
the TTF header), this causes problems when the hinting program uses
the phantom points (misplaced and distorted glyphs) due to the
metrics being unset (all zeros).
(tt_get_metrics_incr_overrides): Renamed to...
(tt_get_metrics_incremental): ... this. Updated caller
* include/freetype/ftincrem.h: Update the documentation to make it
clearer that `get_glyph_metrics` is to retrieve metrics from a
non-standard source, but *not* for the purpose of imposing custom
metrics.
2020-12-14 Werner Lemberg <wl%gnu.org@localhost>
[type42] Pacify static analysis tools (#59682).
* src/type42/t42objs.c (T42_Size_Init, T42_GlyphSlot_Init): Avoid
warnings about uninitialized variables.

* src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`.
2020-12-07 Werner Lemberg <wl%gnu.org@localhost>
*/*: s/FT_LOGGING/FT_DEBUG_LOGGING/.
2020-12-05 Werner Lemberg <wl%gnu.org@localhost>
* builds/toplevel.mk (do-dist): Remove `submodules` directory.
2020-12-02 Werner Lemberg <wl%gnu.org@localhost>

prefix (if requested).
2020-12-02 Werner Lemberg <wl%gnu.org@localhost>
[base] Don't close 'stderr' after logging.

Also make file copying work with non-Unix platforms (untested).
2020-12-01 Werner Lemberg <wl%gnu.org@localhost>
[build] Use gcc (and clang) in C99 mode.
Other compilers are unchanged.
* builds/compiler/gcc-dev.mk, builds/compiler/gcc.mk (ANSIFLAGS):
s/-ansi/-std=c99/.
* builds/freetype.mk (FT_CFLAGS): Remove `-std=c99`.
* builds/unix/configure.raw: Handle C99.
Remove no longer needed test for gcc 4.6 and earlier.
2020-12-01 Werner Lemberg <wl%gnu.org@localhost>
[dlg] Fix compiler warnings.
* src/dlg/dlgwrap.c: Duplicate some feature test macros from
`dlg.c`, which must come first before loading standard headers. For
example, `freetype.h` loads `stdio.h` if compiled in debug mode.
2020-12-01 Werner Lemberg <wl%gnu.org@localhost>
* src/type42/t42parse.c: Fix `-Wformat` warnings.
2020-12-01 Priyesh Kumar <priyeshkkumar%gmail.com@localhost>
[builds/unix] Check for 'pthread' library.
* builds/unix/ax_pthread.m4: New file, taken from 'autoconf-archive'
git repository.
