| [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). |
| |
| * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Redefine to rhyme |

| |
| [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'. |

| |
| [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... |
| * include/freetype/config/public-macros.h: ...this new file. |
| |
| * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, |

| by the library but not to be exposed to clients to... |
| * 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. |
| |
| * CMakeLists.txt, builds/unix/configure.raw: Updated. |

| |
| [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. |

| |
| [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' |
| fails to allocate one of the `internal->subfont' variables, make |
| sure to free `internal->topfont' and any successfully allocated |
| subfonts. |

| [cff, cid] Fix segfaults in case of error (#58621). |
| |
| * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c |
| (cid_slot_done): If `ft_glyphslot_init' fails to allocate |
| `internal', then the class' `done_slot' callback (called by |
| `ft_glyphslot_done') must not dereference the pointer to `internal'. |

| |
| Make macros for header file names optional. |
| |
| We no longer have to take care of the 8.3 file name limit; this |

| |
| */*: Replace |

| [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. |
| |
| Problem report in |
| |
| https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html |
| |
| * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to |
| `inflateInit2' depending on whether the system installation is |
| being used or the internal copy. |

| |
| [truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923). |
| |
| By resetting the blend as implemented with this commit fonts with |
| invalid `gvar' tables may keep calling into `ft_var_load_gvar' from |
| `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. |
| Reset the blend (particularly `blend->glyphoffsets') on failure. |

| The libs which cmake controls are commented out at |
| |
| include/freetype/config/ftoption.h |
| |
| and cmake un-comment each enabled library, but the brotli option was |
| not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained |

| call `get_x_mins' which does the necessary work. |

| [sfnt] Support `face->num_faces' for WOFF2 fonts. |
| |
| Set correct value of `face->num_faces' for WOFF2 fonts. This is |

| requested font face in `woff2_open_font' and create a single-face |
| sfnt stream. |

| changes. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Avoid too many calls to `FT_REALLOC'. |
| |
| We do this by using `totalSfntSize' as an initial reference, and |
| extending the buffer when required. This reduces rendering time |
| considerably. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add |
| `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. |
| |
| * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep |
| track of and update total size of stream. |
| |
| (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. |
| |
| (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, |
| reconstruct_font): Update parameters to accept `sfnt_size'. |
| |
| (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field |
| `totalSfntSize' as initial reference (if value makes sense) and |
| allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' |
| handles reallocation if and when required. Also resize the stream |
| to `actual_sfnt_size' after reconstruction. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Reconstruct `loca', `hmtx', and swap out stream. |
| |
| Add necessary functions to reconstruct loca and hmtx tables (the two |
| remaining tables that can have a transform). `woff2_open_font' is |
| now capable of loading a woff2 font face. This code may still need |
| more refining and better memory management. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total |
| (final) size of sfnt stream. |
| |
| (WOFF2_InfoRec): Add header checksum value. |
| |
| * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' |
| parameter to its pointer so its value can be modified by |
| `woff2_open_font'. |
| |
| * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into |
| sfnt buffer at given position. |
| |
| (write_buf): Add parameter `extend_buf' which allows caller to |
| specify whether buffer should be reallocated before copying data. |
| |
| (WRITE_SFNT_BUF): Updated. |
| |
| (pad4, store_loca, reconstruct_htmx): New functions. |
| |
| (reconstruct_glyf): Calculate loca values and store them. |
| |
| (reconstruct_font): Call `reconstruct_hmtx', write table record |
| entries, and calculate table checksums. Also calculate font |
| checksum and update `checksumAdjustment' entry in head table. |
| |
| (woff2_open_font): Open stream for sfnt buffer, swap out input |
| stream and return. |
| |
| * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept |
| pointer to `face_index'. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Reconstruct transformed `glyf' table. |
| |
| Reconstruct `glyf' table if it is transformed in the uncompressed |
| table stream. Also add necessary structures, macros and functions. |
| |
| * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, |
| WOFF2_SubstreamRec, WOFF2_PointRec): New structures. |
| (WOFF2_TableRec): s/OrigLength/dst_length/. |
| |
| * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use |
| `FT_SET_ERROR' to set implicit `error' variable. |
| |
| (WRITE_SHORT): New macro. |
| |
| (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, |
| COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to |
| refer to substreams of the transformed `glyf' tables. |
| |
| (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' |
| macros. |
| |
| (with_sign, safe_int_addition): New functions to add sign to values |
| based on a flag and perform safe addition respectively. |
| |
| (triplet_decode): Decode variable-length (flag, xCoordinate, |
| yCoordinate) triplet for a simple glyph. See |
| |
| https://www.w3.org/TR/WOFF2/#triplet_decoding |
| |
| (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): |
| New functions. |
| |
| (reconstruct_font): Call `reconstruct_glyf'. |
| |
| * src/sfnt/sfwoff2.h: Add required constants. |
| |
| * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. |

| [woff2] Copy un-transformed tables to sfnt stream. |
| |
| Copy un-transformed tables to the sfnt stream. |
| |
| * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. |
| (write_buf): New function. Extend memory of `dst' buffer and copy |
| bytes from `src'. |
| (compute_ULong_sum): New function. Calculate checksum of table. |
| (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** |
| sfnt_bytes'. This has been done because we reallocate memory to |
| `sfnt' multiple times, which may change the pointer value of `sfnt'. |
| This new pointer must be propogated back to the caller. Same reason |
| for using a double pointer in `write_buf'. |
| |
| * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for |
| overflow checking. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |

| |
| Perform basic checks and start iterating over tables. |

| New functions. |
| (reconstruct_font): Modify parameters and iterate over tables. |
| (woff2_open_font): Updated. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Handle TTCs and start reconstructing font. |
| |
| We `handle' TTCs by modifying the `indices' array to point to only |
| those tables that are part of the requested `face_index'. |
| |
| Set and use `num_tables' in `WOFF2_TtcFont'. |
| |
| * src/sfnt/sfwoff2.c (reconstruct_font): New function. |
| (woff2_open_font): Start reconstruction of font. |
| |
| 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> |
| |
| [woff2] Get known tags from function. |
| |
| Change `KnownTags' to a function (`woff2_known_tags'). This avoids |
| introducing a global constant array. This function returns the |
| specified index without *any* checks. The caller must ensure that |
| `index' is within array limits. |
| |
| * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' |
| notation to `woff2_known_tags( ... )'. |
| |
| * src/sfnt/woff2tags.c: Perform changes. |
| |
| * src/sfnt/woff2tags.h: Update definitions. |

| |
| [woff2] Uncompress Brotli streams and `face_index' support. |
| |
| WOFF2 compressed stream is now uncompressed if Brotli is available. |
| This data is stored in a separate buffer (uncompressed_buf) because |
| it does not contain direct table data. Certain tables have |
| transformations applied to them, and they must be reconstructed |
| before we can write those tables to the SFNT stream. |
| |
| `face_index' is now being passed as a parameter to |
| `woff2_open_font'. |
| |
| * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter |
| `face_instance_index'. |
| |
| * src/sfnt/sfwoff2.c (woff2_uncompress): New function. |
| (woff2_open_font): Call `woff2_uncompress'. |

| |
| [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). |
| |
| As originally intended, a Type 1 SEAC charstring would be used for |
| an accented glyph (like `acaron' or `uumlaut'), where the advance |
| width of the SEAC glyph is the same as that of the `base' glyph |
| (like `a' or `u'). In this case it is not uncommon for the SEAC |
| glyph to not use an (H)SBW opcode of its own but to rely on the |
| value from the base glyph. |
| |
| However, out-of-spec fonts also use SEAC glyphs for ligatures (like |
| `oe' or `fi'), and in those cases the overall advance width is |
| greater than that of the `base' glyph. For this reason we have to |
| allow that the SEAC glyph can have an (H)SBW value of its own, and |
| if it has, retain this value, rather than the one from the base |
| glyph. |
| |
| * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: |
| Implement it. |

| [smooth] Restore the span buffering for direct mode only. |
| |
| The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be |

| [smooth] Simplify cubic Bézier flattening. |
| |
| The previous implementation is correct but it is too complex. |
| The revised algorithm is based on the fact that each split moves |
| the control points closer to the trisection points on the chord. |
| The corresponding distances are good surrogates for the curve |
| deviation from the straight line. |
| |
| This cubic flattening algorithm is somewhat similar to the conic |
| algorithm based the distance from the control point to the middle of |
| the chord. The cubic distances, however, decrease less predictably |
| but are easy enough to calculate on each step. |
| |
| The new algorithm produces slightly larger number of splits, which is |
| compensated by its simplicity. The overall rendering performance is |
| improved by 1-2%. The larger number of splits does not necessarily |
| result in higher quality, which stays comparable. |
| |
| * src/smooth/ftgrays.c (gray_render_cubic): Replace the split |
| condition. |

| |
| Optimize Bézier bisections. |
| |
| This change makes bisections faster by 20-30%. When inlined into |
| `gray_render_cubic', this makes the function faster by 10% and is |

| [pcf] Fix handling of undefined glyph (#56067). |
| |
| This commit fixes the changes from 2018-07-21, which broke charmap |

| index 0, thus increasing the number of glyphs by one (as before). |

| |
| Fix handling of `FT_Bool'. |
| |
| Before this commit we had code like |
| |
| (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) |
| |
| Since `FT_Bool' is defined to be an `unsigned char', the code |
| evaluated to something like |
| |
| (unsigned char)( 0x8532 & 0x8000) |
| |
| which in turn expanded to |
| |
| (unsigned char)( 0x8000) |
| |
| and finally yielded 0x00 – i.e., false – not as expected. |
| |
| Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. |
| |
| * include/freetype/fttypes.h (FT_BOOL): Add a comparison against |
| zero so that we always have a Boolean expression. |
| |
| */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where |
| possible. |

| with continuous prediction. |
| |
| 2018-09-22 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Another tweak. |
| |
| This one should be clearer. When the rounded monochrome bbox collapses |
| we add a pixel that covers most if not all original cbox. |
| |
| 2018-09-21 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Further tweak. |
| |
| 2018-09-21 Ben Wagner <bungeman@google.com> |
| |
| Improve auto-hinter handling of bitmap fonts (#54681). |
| |
| For bitmap fonts, `FT_Load_Glyph' should either return an error or |
| not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this |
| case `FT_Load_Glyph' calls into the auto-hinter which calls back |
| into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which |
| marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path |
| (even though it doesn't have any path). It appears that the |
| auto-hinter should not be called when the face doesn't have |
| outlines. The current test for using the auto-hinter in |
| `FT_Load_Glyph' checks whether the driver supports scalable |
| outlines, but not if the face supports scalable outlines. |
| |
| * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have |
| scalable outlines. |
| |

| |
| [raster] Fix disappearing vertical lines (#54589). |

| |
| 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak. |
| |
| This adds pixels in case a contour goes through the center |
| and they need to be turned on in the b/w rasterizer. |
| |
| 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [pcf] Replace charmap implementation. |
| |
| PCF comes with charmap lookup table, aka PCF encodings. Using it |
| directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times |
| faster than the original BDF-like binary searches. |
| |
| * src/pcf/pcf.h (PCF_EncodingRec): Removed. |
| (PCF_FaceRec): Remove `nencodings' and `encodings'. |
