| |
| * 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 |
| directory that is not directly inside the source tree, so the path |
| `../tests/data/As.I.Lay.Dying.ttf` does not resolve to the test |
| input file. This change passes the test data directory as an |
| environment variable to allow arbitrary build directories. |
| |
| * tests/meson.build: Updated. |
| |
| 2021-07-16 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> |
| |
| * tests/issue-1063/main.c (main): Fix uninitialized variable. |
| |
| I tried running `meson test` but the test just crashed and gdb |
| reported that the face argument to `FT_Get_Char_Index` was nonsense. |
| With this change the test prints 'Could not open file: ' as it |
| should. |

| |
| [smooth] Minor fixes. |
| |
| * src/smooth/ftgrays.c (gray_render_conic): Move variable and |
| structure declarations to beginning of function. In spite 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. |
| |
| 2021-07-15 Ben Wagner <bungeman@chromium.org> |
| |
| * 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 |
| available, or on 64-bit CPUs. |
| |
| On a 2017 Core i5-7300U CPU on Linux/x86_64: |
| |
| ftbench -p -s10 -t5 -cb DroidSansFallbackFull.ttf |
| |
| Before: 4.033 us/op (best of 5 runs for all numbers) |
| After: 3.876 us/op |
| |
| ftbench -p -s60 -t5 -cb DroidSansFallbackFull.ttf |
| |
| Before: 13.467 us/op |
| After: 13.385 us/op |
| |
| * src/smooth/ftgrays.c (gray_render_conic): New implementation |
| based on DDA and optionally SSE2. |

| |
| [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) |

| |
| Before: 17.988 us/op |
| After: 17.389 us/op |
| |
| * src/smooth/ftgrays.c (gray_TWorker): Replace `num_cells` field with |
| `cell_free` and `cell_limit`. |
| (NULL_CELL_PTR, CELL_MAX_X_VALUE, CELL_IS_NULL): New macros. |
| (gray_dump_cells, gray_set_cell, gray_sweep, gray_sweep_direct, |

| [tests] Rewrite download script in Python3. |
| |
| This commit replaces the bash script with a Python script that does |
| the same work, plus avoiding to download anything if the files are |
| already installed with the right content. |
| |
| We now use the first 8 bytes of each file's sha256 hash for the |
| digest. |

| * tests/scripts/download-test-fonts.sh: Removed. |
| * tests/scripts/download-test-fonts.py: New script. |

| |
| 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`. |

| |
| [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> |
| |
| [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> |
| |
| * 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. |

| [autofit] More clean-ups. |
| |

| src/autofit/afloader.c (af_loader_load_glyph): Updated. |
| |
| 2021-07-12 Werner Lemberg <wl@gnu.org> |
| |
| Small clean-ups for the last few commits. |

| |
| 2021-07-12 David Turner <david@freetype.org> |
| |
| Remove experimental auto-hinting 'warp' mode. |
| |
| This feature was always experimental, and probably never worked |
| properly. This patch completely removes it from the source code, |
| except for a documentation block describing it for historical |
| purposes. |
| |
| * devel/ftoption.h, include/freetype/config/ftoption.h: Remove |
| `AF_CONFIG_OPTION_USE_WARPER`. |
| |
| * include/freetype/ftdriver.h: Document 'warping' property as |
| obsolete. |
| |
| * src/autofit/afwarp.c, src/autofit/afwarp.h: Files removed. |
| * src/autofit/*: Remove any code related to warp mode. |
| |
| 2021-07-12 David Turner <david@freetype.org> |
| |
| Remove experimental 'Latin2' writing system (`FT_OPTION_AUTOFIT2`). |
| |
| This code has always been experimental and was never compiled anyway |
| (`FT_OPTION_AUTOFIT2` does not appear in `ftoption.h` or even any of |
| our build files). |
| |
| * include/freetype/internal/fttrace.h (aflatin2): Removed. |
| * src/autofit/aflatin2.h, src/autofit/aflatin2.c: Files removed. |
| * src/autofit/afloader.c: Remove undocumented hook to activate |

| |
| * 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` |
| explicitly call `tt_set_mm_blend` with `coords` as `NULL`. In |
| addition, `TT_Set_MM_Blend` has a similar possible issue. |

| [sfnt] Support PaintScale in 'COLR' v1 parsing. |
| |

| |
| [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. |

| |
| The second pass also fixes horizontal lines through the pixel centers. |

| |
| 2021-06-28 Dominik Röttsches <drott@chromium.org> |
| |
| [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. |
| |
| 2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [raster] Clean up vertical sweep. |
| |

| |
| [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 |

| [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 |

| [smooth, raster] Fix up and align error codes. |
| |
| FT_Render_Glyph picked up FAILURE or 1 returned from the raster |

| [autofit] Fix return value of `FT_Load_Glyph`. |
| |
| * src/autofit/afglobal.c (af_face_globals_get_metrics): The issue is |
| that `style_metrics_init` sometimes returns -1 without clearing |
| `error`. While looping to `Again`, the next operation is |
| successful, but -1 is still returned by the function. The fix is to |
| set `error` to 0 appropriately. |
| |
| Fixes #1063. |

| |
| [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 |
| to use the entire 8-bit range efficiently. For example: if we use |
| 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. |
| |

| required. |
| |
| * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit |
| bitmap instead of 16-bit buffer. |
| |
| * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert |

| |
| * src/sdf/ftsdf.c (sdf_generate_with_overlaps, |

| |
| * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead |
| of 16-bit buffer. |

| |
| [type42] Fix auto-hinting. |
| |
| The autohinter could not access the base (unscaled) outline in the |

| |
| * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts |

| required. This is based on HALX99's merge request at |
| https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests/31 |
| 2. Update FindHarfBuzz.cmake from |
| https://github.com/WebKit/WebKit/blob/1ce32454/Source/cmake/FindHarfBuzz.cmake |
| and guard post-CMake-3.1 features to keep the minimum version unchanged |
| 3. Update FindBrotliDec.cmake to stop the warnings, based on what |
| https://github.com/google/woff2/blob/a0d0ed7d/cmake/FindBrotliDec.cmake |
| is doing |
| |
| * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Implement 1 and 2. |

| |
| [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`. |
| |
| 2021-05-18 Alexei Podtelezhnikov <apodtele@gmail.com> |

| * src/smooth/ftgrays.c (FT_MAX_GRAY_SPANS): Increase from 10 to 16. |
| |
| Ten was barely enough for two slanted stems. Sixteen can actually fit |
| a bit more complicated scanlines. |
| |

| |
| [smooth] Faster bitmap sweeping. |
| |
| Selecting the fill rule or checking the direct mode each time we call |
| `gray_hline' is sub-optimal. This effectively splits the direct mode |
| into a separate code path while inlining `gray_hline' and saving 5-7% |
| of rendering time. |
| |
| * src/smooth/ftgrays.c (gray_hline): Eliminated in favor of... |
| (FT_FILL_RULE, FT_GRAY_SET): ... these new macros... |
| (gray_sweep): ... inlined here. |
| (gray_sweep_direct): New function that handles the direct span buffer. |
| (gray_TWorker): Remove the span buffer. |
| (gray_raster_render, gray_convert_glyph): Updated. |

| [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. |

| |
| [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. |
| |
| * src/truetype/ttinterp.h (TT_ExecContextRec): New fields |
| `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, |
| `glyfStorage`, and `origStorage`. |

| [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'. |
| |
| * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak of `rows`. |

| |
| * src/sfnt/sfwoff2.c (woff2_open_font): Reject fonts that have |

| reliably if table tags are unique. |
| |

| |
| [unix] Updates for autoconf 2.71. |

| |
| * builds/toplevel.mk: Fix previous commit. |
| |
| <top_level>: Use `TOP_DIR` in `wildcard` function. |
| (check_out_submodule, copy_submodule): Move down to come after |
| definition of `all` rule. |
| Call `mkdir` conditionally. |
| |
| 2021-02-16 Werner Lemberg <wl@gnu.org> |
| |
| * builds/toplevel.mk: Use rules for handling 'dlg'. |
| |
| Suggested by Alexei. |
| |
| (check_out_submodule, copy_submodule): New targets. |
| <top-level>: Replace calls to `shell` with rules. |
| |
| 2021-02-16 Werner Lemberg <wl@gnu.org> |
| |
| * builds/toplevel.mk: Avoid side effects of `shell`. |
| |
| We use a dummy variable to catch its output. Otherwise the `make` |
| program is going to interpret the return value of `shell`; this can |
| cause obscure warning or error messages or even be harmful. |
| |
| 2021-02-16 Werner Lemberg <wl@gnu.org> |
| |
| Move 'dlg' submodule to `subprojects` directory. |
| |
| This is for future changes with Meson, which doesn't allow a |
| different name for its `subprojects` directory. Having both a |
| `submodules` and a `subprojects` directory is confusing. |
| |
| * .gitmodules, autogen.sh (copy_submodule_files, DLG_INC_DIR, |
| DLG_SRC_DIR): Updated. |
| |
| * builds/toplevel.mk (<top-level>, do-dist), |

| |
| 2021-02-16 Dominik Röttsches <drott@chromium.org> |
| |
| [sfnt] Update paint format values to support non-variable paints. |
| |
| * freetype.h (FT_PaintFormat): Update paint format identifiers after |
| a specification change. The specification was updated to have |
| sibling formats, variable and non-variable variants for each. |
| Reflect that here. |
| |
| * sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as |
| the non-variable formats no longer have them. |
| |
| 2021-02-15 Daniel E <daniel.engberg.lists@pyret.net> |
| |
| * CMakeLists.txt: Improve 'bz2' support. |
| |
| Not all distributions such as FreeBSD provide a `.pc` file for |
| '(lib)bz2' so follow autotools and add it to `Libs.private` instead. |
| |
| 2021-02-13 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/update-copyright-year: Fix single-year entry handling. |
| |
| The fix from 2021-01-17 didn't cover the case where the year to be |
| updated is identical to the current year. |
| |
| 2021-02-13 Werner Lemberg <wl@gnu.org> |
| |
| Add new function `FT_Get_Transform`. |
| |
| See |
| |
| https://github.com/harfbuzz/harfbuzz/issues/2428 |
| |
| for some reasons to introduce this function. |
| |
| * include/freetype/freetype.h, src/base/ftobjs.c (FT_Get_Transform): |
| Implement it. |
| |
| 2021-02-12 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| Decorate `qsort` callbacks with `cdecl`. |
| |
| * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): |

| |
| * src/base/ftrfork.c, src/bdf/bdflib.c, src/gxvalid/gxvcommn.c, |
| src/psaux/afmparse.c, src/psnames/psmodule.c, src/type1/t1afm.c, |
| src/sfnt/sfwoff.c, src/sfnt/sfwoff2.c: Update `qsort` callbacks. |
| |
| Fixes #1026 when compiling FreeType with an unusual calling |
| convention while the C library function `qsort` still expects |
| `cdecl`. |
| |
| 2021-02-10 Dominik Röttsches <drott@chromium.org> |
| |
| [sfnt] Implement 'COLR' v1 sweep gradients. |
| |
| * freetype.h (FT_PaintSweepGradient): Add `FT_PaintSweepGradient` to |

| Update format. |
| (FT_PaintFormat): Update shifted paint formats. |
| Sync with spec. |
| * sfnt/ttcolr.c (read_paint): Logic to parse sweep gradients. |

| |
| 2021-02-09 Dominik Röttsches <drott@chromium.org> |
| |
| [sfnt] Provide optional root transform for 'COLR' v1 glyph graph. |
| |
| * include/freetype/freetype.h (FT_Get_Color_Glyph_Paint): |
| Additional function argument `root_transform` to control whether |
| root transform should be returned. |
| (FT_OpaquePaint): Additional tracking field to denote whether |
| root transform is to be returned. |
| * include/freetype/internal/sfnt.h |
| (TT_Get_Color_Glyph_Paint_Func): Propagate additional argument. |
| * src/base/ftobjs.c (FT_Get_Color_Glyph_Paint): Ditto. |
| * src/sfnt/ttcolr.c (tt_face_get_colr_glyph_paint): Return root |
| transform reflecting the size and tranform configured on |
| `FT_Face`. |
| (read_paint): Initialize and track status of insert_root_transform |
| flag. |
| |
| 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> |
| |
| * 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> |
| |
| [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. |
| |
| 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> |
| |
| [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. |

| 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> |
| |
| * 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> |
| |
| * 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> |
| |
| * 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> |
| |
| * 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> |
| |
| * meson.build: Set project version. |

| |
| [base] Fix Netpbm tracing message. |

| warning if there is nothing to output. |
| |
| 2021-02-04 Werner Lemberg <wl@gnu.org> |
| |
| * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. |
| |
| This ensures good logging output, with all lines having a proper |
| prefix (if requested). |
| |
| This is a continuation of a similar patch from 2020-12-02, which |
| missed some locations. |

| modify `ftexport.sym` conditionally. |
| |
| Problem reported by Alexei. |
| |
| * src/base/ftdebug.c: Include `ftlogging.h`. |

| a temporary solution until 'COLR' v1 support is released in a |
| FreeType version and such a check can be made by using the version |
| number instead. |

| |
| 2020-08-16 Anuj Verma <anujv@iitbhilai.ac.in> |
| |
| [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> |
| |
| 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> |
| |
| [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> |
| |
| * 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> |
| |
| * meson.build (ft2_defines): Fix builds on Windows. |
| |
| 2020-12-18 Tatsuyuki Ishi <ishitatsuyuki@gmail.com> |
| |
| [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> |

| |
| 2020-12-16 Chris Liddell <chris.liddell@artifex.com> |
| |
| [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> |
| |

| warnings about uninitialized variables. |
| |
| 2020-12-07 Werner Lemberg <wl@gnu.org> |
| |
| * builds/unix/configure.raw: Don't set `FT_DEBUG_LOGGING`. |

| All debug options are handled exclusively in `ftoption.h`. |
| |
| 2020-12-07 Werner Lemberg <wl@gnu.org> |
| |

| |
| 2020-12-02 Werner Lemberg <wl@gnu.org> |
| |
| * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. |
| |
| This ensures good logging output, with all lines having a proper |
| prefix (if requested). |
| |
| 2020-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [base] Don't close 'stderr' after logging. |
| |

| |
| * autogen.sh (copy_submodule_file), builds/toplevel.mk: Redirect |
| stderr to `/dev/null`. |
| |
| * builds/toplevel.mk: Move code block to handle 'dlg' stuff into |
| `check_platform` conditional. |
| Also fix wildcard expressions for guarding `git submodule` commands. |
| Also make file copying work with non-Unix platforms (untested). |
| |
| 2020-12-01 Werner Lemberg <wl@gnu.org> |
| |
| [build] Use gcc (and clang) in C99 mode. |
| |

| it works. |
| |
| 2020-12-01 Werner Lemberg <wl@gnu.org> |

| |
| [builds/windows] Changes to build 'dlg' with FreeType on Windows. |
| |
| We only support Visual C++ 2010 and newer. |
| |
| * builds/windows/vc2010/script.bat: New windows batch file to copy |

| platforms. |
| (DisableLanguageExtensions): We need to disable the `/Za` option |
| when building 'dlg' with FreeType as 'dlg' strictly follows the C99 |
| standard. Visual C++ produces behaves unexpectedly when |
| compiling a C99 file with `/Za` option enabled. |

| |
| [autofit] Synchronize with ttfautohint. |
| |
| This corresponds to the following commits in the ttfautohint git |
| repository: |
| |
| bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting. |
| d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script. |
| |
| * src/autofit/afblue.dat: Add blue zone data for Medefaidrin. |
| * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. |
| |
| * src/autofit/afscript.h: Add Medefaidrin standard characters. |
| |
| * src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin |
| data. |
| |
| 2020-09-25 Werner Lemberg <wl@gnu.org> |
| |
| Move `scripts/make_distribution_archives.py` to `src/tools`. |
| |
| * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR, |
| _SCRIPT_DIR): Updated to new location. |
| (main): s/shutils.copyfile/shutils.copy/ to preserve file |
| permissions. |
| (main): Prefix source file paths with `git_dir` while copying files |
| to allow calls of the script from other places than the top-level |
| directory. |
| |
| 2020-09-24 Werner Lemberg <wl@gnu.org> |
| |
| * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. |
| |
| Towards the end of the the function there is a call to |
| `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. |
| That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` |
| is left alone, and is not scaled. |
| |
| Patch from Eric Muller <emuller@amazon.com>. |
| |
| 2020-09-24 Werner Lemberg <wl@gnu.org> |
| |
| * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. |
| |
| 2020-09-22 Werner Lemberg <wl@gnu.org> |
| |
| [meson] Move auxiliary scripts to `builds/meson`. |
| |
| Suggested by Alexei. |
| |
| * scripts/*.py: Move meson scripts to... |
| * builds/meson/*.py: ... this new location. |
| |
| * meson.build: Updated. |
| |
| 2020-09-21 David Turner <david@freetype.org> |
| |
| Add python script for building tarballs. |
| |
| * scripts/make_distribution_archives.py: New file. |
| |
| This standalone Python script should be equivalent to running `make |
| dist` with the Make-based build system, with the following minor |
| differences: |
| |
| - Since `make distclean` doesn't always clean up `objs/` properly, |
| `make dist` archives may contain some stale binaries like |
| `objs/.libs/libfreetype.so.6` or others. |
| |
| - `config.guess` and `config.sub` are not updated unless option |
| `--gnu-config-dir=DIR` is used to specify the location of these |
| files. |
| |
| - Some bits of the auto-generated reference documentation may |
| appear in slightly different order, probably due to issues related |
| to mkdocs and docwriter. |
| |
| As an example, the call |
| |
| scripts/make_distribution_archives.py /tmp/freetype2-dist |
| |
| creates the following files under `/tmp/freetype2-dist`: |
| |
| freetype-<version>.tar.gz |
| freetype-<version>.tar.xz |
| ft<winversion>.zip |
| |
| 2020-09-21 Werner Lemberg <wl@gnu.org> |
| |
| * scripts/extract_freetype_version.py: Fix regex typos. |
| |
| 2020-09-21 David Turner <david@freetype.org> |
| |
| Add Meson build project file. |
| |
| Example usage: |
| |
| # Configure Meson build in directory `build-meson` to generate |
| # release binaries comparable to to the ones from the |
| # autotools/make build system. |
| meson setup build-meson \ |
| --prefix=/usr/local \ |
| --buildtype=debugoptimized \ |
| --strip \ |
| -Db_ndebug=true |
| |
| # After configuring the Meson build with the above command, |
| # compile and install to `/usr/local/`; this includes a pkg-config |
| # file. |
| ninja -C build-meson install |
| |
| # Alternatively, compile and install to `/tmp/aa/usr/local/...` |
| # for packaging. |
| DESTDIR=/tmp/aa ninja -C build-meson install |
| |
| # Generate documentation under `build-meson/docs`. |
| ninja -C build-meson docs |
| |
| Library size comparison for stripped `libfreetype.so` generated by |
| all three build systems: |
| |
| - Default build (autotools + libtool): 712 KiB |
| - CMake build (RelWithDebInfo): 712 KiB |
| - Meson build: 712 KiB |
| |
| |
| * meson.build: New top-level Meson build file for the library. |
| |
| * meson_options.txt: New file. It holds user-selectable options for |
| the build, which can be printed with `meson configure`, and selected |
| at `meson setup` or `meson --reconfigure` time with |
| `-D<option>=<value>`. |
| |
| * scripts/parse_modules_cfg.py: A script invoked by `meson.build` to |
| parse `modules.cfg` and extract important information out of it |
| (i.e., the list of modules). |
| |
| * scripts/process_ftoption_h.py: New script invoked by `meson.build` |
| to process the original `ftoption.h` file. It enables or disables |
| configuration macro variables based on the available dependencies. |
| This is similar to what other build systems are using (i.e., Meson's |
| `configure_file()` command is not used here). |
| |
| * scripts/extract_freetype_version.py: New script invoked by |
| `meson.build` to extract the FreeType version number from |
| `<freetype/freetype.h>`. |
| |
| * scripts/extract_libtool_version.py: New script invoked by |
| `meson.build` to extract the libtool `revision_info` data from |
| `builds/unix/configure.raw`, and to generate the corresponding |
| shared library suffix. |
| |
| * scripts/generate_reference_docs.py: New script invoked by |
| `meson.build` to generate the FreeType 2 reference documentation |
| (using the `docwriter` and `mkdocs` packages, which must be already |
| installed). |
| |

| |
| [raster] Improve the second pass (#58373). |
| |
| Besides dropout control the second horizontal sweep is supposed to |
| clean up straight horizontal edges that are mishandled by the first |
| vertical sweep when a line passes through pixel centers. This line |
| would present as perfectly aligned span edges in the second sweep. |
| |
| * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old |
| implementation with a better one focusing on aligned span edges only. |
| |
| 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [raster] Tune SMART macro (#58352). |
| |
| Windows seems to perform smart dropout control at 26.6 precision. |
| To mimick Windows independent of increased precision, we need to tweak |
| the macro so that some close calls break down rather than up. |
| |
| * src/raster/ftraster.c (SMART): Tweak the macro. |
| |
| 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> |

| [truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND. |
| |
| For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set |
| FT_OUTLINE_OVERLAP to render them with direct oversampling, which |
| mitigates artifacts (see 3bb512bc9f62). |
| |

| [build] Really fix multi and C++ builds. |
| |
| The following builds were still failing due to previous changes: |
| |
| make multi |
| make multi CC="c++" |
| make CC="c++" |
| |
| This patch fixes the issues, which were missing includes to get the |
| right macro definitions in multi-build mode. |
| |
| Also, `FT_UNUSED' is actually used by third-party code, so move it |
| back to `public-macros.h' to avoid breaking it. |
| |
| * include/freetype/config/public-macros.h (FT_EXPORT): Remove |
| special definition for C++. |
| (FT_UNUSED): Define here instead of... |
| * include/freetype/config/compiler-macros.h: ... here. |
| (FT_FUNCTION_DECLARATION): Remove special definition for C++. |
| (FT_LOCAL_ARRAY_DEF): Fix definition. |
| |
| * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h, |
| src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'. |

| [psaux] Improve `t1_decoder_parse_metrics' (#58646). |
| |
| * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy |

| |
| [build] Improve visibility support of library function names. |
| |
| * include/freetype/config/public-macros.h |
| (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as |
| public (and thus exportable). |
| (FT_EXPORT): Use it. |
| |
| * include/freetype/config/compiler-macros.h |
| (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as |
| internal to the library (and thus hidden). Note that on ELF |
| systems, all internal functions have hidden visibility, which avoids |
| the need to enforce this when invoking the compiler (e.g., with an |
| option like `-fvisibility=hidden'). |
| |
| (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros |
| to deal with C and C++ linkage issues at the same time. |
| |
| (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, |
| FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, |
| FT_BASE_CALLBACK_DEF): Redefined using new macros. |

| [build] Split off more stuff from `ftconfig.h'. |
| |
| * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, |
| include/freetype/config/ftconfig.h: Split off macro definitions |
| required by the FreeType API headers to... |

| |
| * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, |

| * include/freetype/config/compiler-macros.h: ...this new file. |
| |
| * include/freetype/internal/*.h, src/raster/ftraster.h: Include |

| [build] Move mac support code to `mac-support.h'. |
| |
| * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, |

| to... |
| * include/freetype/config/mac-support.h: ...this new file. |
| |
| * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> |
| #undef' string replacement; the affected code is no longer part of |
| the `ftconfig.h' template. |
| |
| 2020-07-05 David Turner <david@freetype.org> |
| |
| [build] Put integer type definitions into `integer-types.h'. |
| |
| Refactor some of the `ftconfig.h' headers and template to move the |
| definition of the FreeType integer types (e.g., `FT_Int16') to a |
| common header file `freetype/config/integer-types.h'. |
| |
| * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, |

| definition stuff to... |
| * include/freetype/config/integer-types.h: ...this new file. |
| |
| * builds/unix/ftconfig.h.in: Control the definition of |
| `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro |
| `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto |
| detection happens in `integer-types.h' as usual based on `INTXX_MAX' |
| values. Otherwise the autoconf-detected values are used. |
| |
| * builds/unix/configure.raw (CPPFLAGS): Don't include path to |
| `config' directory. Instead, ... |
| (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path. |
| |
| 2020-07-05 David Turner <david@freetype.org> |
| |
| [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'. |
| |
| Since we are no longer limited to 8.3 file names, it is simpler to |
| follow the usual conventions for template files. |
| |
| * builds/unix/ftconfig.in: Renamed to... |
| * builds/unix/ftconfig.h.in: ...this. |

| |
| [smooth] Introduce direct oversampling for overlaps. |
| |
| This implements oversampling to mitigate artifacts in pixels partially |
| covered by overlapping contours. It turns out that the 4x4 |
| oversampling is sufficient but, at least, quadruples the rendering |
| time. The outline has to set FT_OUTLINE_OVERLAP to use this method. |
| |
| * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. |
| * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... |
| (ft_smooth_raster_overlap): ... inflate outline and set up direct |
| rendering for oversampling with... |
| (ft_smooth_overlap_spans): ... new span function that integrates them. |
| |
| 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [smooth] Use direct rendering mode in Harmony. |
| |
| Instead of rendering 3 bitmaps side by side and reshuffling, we use |
| direct rendering to deliver the bitmaps on each third byte. |
| |
| * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) |
| [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... |

| |
| 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [smooth] Separate LCD paths from gray rendering. |
| |
| This makes `ft_smooth_render' a lot smaller and easier to follow. It |
| also cleanly separates Harmony and ClearType-style LCD rendering |
| algorithms. Now I only wish to move LCD filtering and geometry from |
| FT_Library to FT_Renderer. |
| |
| * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... |
| (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. |
| [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's. |
| |
| 2020-06-20 Sebastian Rasmussen <sebras@gmail.com> |
| |
| [cff] Fix handling of `style_name == NULL' (#58630). |
| |
| * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails |
| by returning NULL in `cff_face_init', `remove_style' is still |
| called. This means that the NULL pointer is dereferenced, causing a |
| crash. |
| |
| 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> |
| |
| [cff] Fix another two memory leaks (#58629). |
| |
| * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' |

| sure to free `internal->topfont' and any successfully allocated |
| subfonts. |
| |
| 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> |
| |
| [psaux] Fix memory leak (#58626). |

| [gzip] Support `gzip' encoded header conditionally. |
| |
| In order to support `gzip' encoded header the call to |
| `inflateInit2' was modified in commit 6a92b1fadde26477a9179. |
| However, this code breaks with the outdated internal version |
| of zlib. This is a temporary fix to conditionally support |
| `gzip' encoded header whenever a system installation of zlib |
| is being used. |

| `tt_set_mm_blend' and failing, but the font was invalid anyway and |
| we want to keep seeing the failure in `tt_set_mm_blend'. |
| |
| * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of |
| offset array once. |
| Allocate arrays after `FT_FRAME_ENTER' (extra check before |
| allocating and avoid needing to free array later if error entering |
| frame). |
| Always call `FT_FRAME_EXIT'. |
| Consistently set counts immediately after array initialized. |

| [base] Fix `NULL + offset' sanitizer warnings (#57194). |
| |
| * src/base/ftgloadr.c (FT_GlyphLoader_Adjust_Points, |
| FT_GlyphLoader_Adjust_Subglyphs): Use `FT_OFFSET'. |
| (FT_GlyphLoader_CreateExtra): Add short cut if some values are zero. |
| |

| |
| * include/freetype/internal/ftmemory.h (FT_OFFSET): New macro. |
| |
| Use this for `base + offset' pointer calculations where `base' can |
| be NULL (triggering a sanitizer warning even if the resulting |
| pointer gets never dereferenced since it is undefined behaviour |
| in C). |
| |
| Suggested by Ben Wagner. |

| Minor fixes for recent compilers. |

| |
| * CMakeLists.txt: Minor additions to the notes, compile |
| builds/unix/ftsystem.c instead of src/base/ftsystem.c on UNIX. |
| |
| The latter change is based on the code proposed by rim in #55235. |
