-
- [base] Remove a check for resource ID in the resource fork driver.
-
- LastResort.dfont has a marginal resource ID 0xFFFF for sfnt
- resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs'
- (1-46), tells that some IDs are reserved and should not be used.
- FreeType2 just uses resource ID to sort the fragmented resource.
- To accept the marginal fonts, the checking is removed.
-
- * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id
- validity check, fix a trace message format.
-
-2017-09-08 suzuki toshiya <[email protected]>
-
- [sfnt, truetype] Register the tags for marginal fonts.
-
- The first 32bit of standard TrueType variants is 0x00010000,
- `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
- OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
- starting 0xA5 followed by `kbd' or `lst'. Considering the following
- data could be parsed as conventional TrueType fonts, the header
- checking is updated to allow these tags. It seems that recent Mac
- OS X has already switched to normal TTF for these fonts.
-
- See the discussion at
- http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
-
- * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
- tags for Keyboard.dfont and LastResort.dfont.
- * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
- starts with TTAG_0xA5kbd or TTAG_0xA5lst.
- * src/truetype/ttobjs.c (tt_face_init): Accept the face with the
- format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

-2017-09-05 Werner Lemberg <[email protected]>
-
- Fix multiple calls of `FT_Bitmap_Convert'.
-
- The documentation of `FT_Bitmap_Convert' says that multiple calls do
- proper reallocation of the target FT_Bitmap object. However, this
- failed for the sequence
-
- non-empty bitmap
- empty bitmap
- non-empty bitmap
-
- Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
- buffer if it became too small; it didn't make the buffer smaller.
- For an empty bitmap following a non-empty one, only the buffer
- dimension got set to zero, without deallocation. If the next call
- was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
- triggered.
-
- * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
- buffer to the correct size.
-
- * docs/CHANGES: Document it.
-
-2017-09-05 Werner Lemberg <[email protected]>
-
- [bdf] Fix size and resolution handling.
-
- * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if
- `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are
- missing.
-
- * docs/CHANGES: Document it.
-

- * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of
- scalars.
- (vector_shuffle): New macro to take care of a different built-in

-2017-08-15 Behdad Esfahbod <[email protected]>
-
- [sfnt] Speed up PNG image loading.
-
- This reduces the overhead of `premultiply_data' by 60%.
-
- * src/sfnt/pngshim.c (premultiply_data): Provide code which uses
- gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a
- time.
-
-2017-08-11 Werner Lemberg <[email protected]>
-
- [sfnt, truetype] Improve handling of missing sbits.
-
- Requested by Behdad.
-
- Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
- entries in the bitmap strike(s) for empty glyphs. Instead, they
- rely that a space glyph gets created from the font's metrics data.
- This commit makes FreeType behave accordingly.
-
- * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
- code.
-
- * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
- to make a distinction between a missing bitmap in a composite and a
- simple missing bitmap.
-
- * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
- bitmap-only font), synthesize an empty bitmap glyph if metrics are
- available.
-
-2017-08-10 Werner Lemberg <[email protected]>
-
- [base] Minor API improvement for default variation axis setting.
-
- * src/base/ftmm.c (FT_Set_MM_Design_Coordinates,
- FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,
- FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0.
-
- * docs/CHANGES: Updated.
-
-2017-08-08 Werner Lemberg <[email protected]>
-
- [psnames] Really fix issue #49949.
-
- We now use a separate preprocessor macro to handle both definition
- and declaration of the glyph name arrays.
-
- * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.
-
- * src/tools/glnames.py (StringTable::dump,
- StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.
- (dump_encoding): Ditto.
- (main): Use `wb' mode for writing the output file, which works on
- Windows also.
-
- * src/psnames/pstables.h: Regenerated.
-
-2017-08-08 Alexei Podtelezhnikov <[email protected]>
-
- [smooth] Harmony LCD rendering.
-
- This is a new technology for LCD-optimized rendering. It capitalizes
- on the fact that each color channel grid is shifted by a third of a
- pixel. Therefore it is logical to render 3 separate monochrome
- bitmaps shifting the outline by 1/3 pixel, and then combine them.
- Importantly, the resulting output does not require additional LCD
- filtering.
-
- * src/smooth/ftsmooth.c (ft_smooth_render_generic)
- [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
- rendering.
-
- * include/freetype/ftlcdfil.h, include/freetype/freetype.h,
- include/freetype/config/ftoption.h, devel/ftoption.h: Updated
- documentation.
-
-2017-08-08 Alexei Podtelezhnikov <[email protected]>
-
- * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.
-

-
-2017-08-05 Werner Lemberg <[email protected]>
-
- [base, truetype] New function `FT_Get_Var_Axis_Flags'.
-
- The reserved `flags' field got a value in OpenType version 1.8.2;
- unfortunately, the public `FT_Var_Axis' structure misses the
- corresponding element. Since we can't add a new field, we add an
- access function.
-
- * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.
-
- * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.
- Updated.
-
- * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory
- of `mmvar' to hold axis flags.
- Fill the axis flags array.
-
- * docs/CHANGES: Updated.
-
-2017-08-03 Nikolaus Waxweiler <[email protected]>
-
- [truetype] Fix metrics of B/W hinting in v40 mode.
-
- Phantom points are now saved outside v40 backwards compatibility
- mode. This fixes the jumping glyphs when switching between v35 and
- v40 monochrome mode.
-
- * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.
-
-2017-08-03 Nikolaus Waxweiler <[email protected]>
-
- [truetype] Do not set any ClearType flags in v40 monochrome mode.
-
- This fixes weird behavior of instructions that resulted in rendering
- differences between v35 and v40 in monochrome mode, e.g., in
- `timesbi.ttf'.
-
- * src/truetype/ttinterp.c (Ins_GETINFO)
- [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check
- `subpixel_hinting_lean'.
-
-2017-08-01 Werner Lemberg <[email protected]>
-
- * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
-
-2017-08-01 Behdad Esfahbod <[email protected]>
-
- [truetype] Fix loading of named instances.
-
- * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position
- while loading the `avar' table.
-
-2017-08-01 Werner Lemberg <[email protected]>
-
- [sfnt, truetype] Minor adjustments for OpenType 1.8.2.
-
- * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now
- (tighter) limits.
-
- * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType
- version explicitly allows all negative values for the number of
- contours if we have a composite glyph (this is for better backwards
- compatibility I guess), but it still recommends value -1.

-
- Handle some integer overflow run-time errors (#46149, #48979).
-
- This commit (mainly for 32bit CPUs) is the first of a series of
- similar commits to handle known integer overflows. Basically, all
- of them are harmless, since they affect rendering of glyphs only,
- not posing security threats. It is expected that fuzzying will show
- up more overflows, to be fixed in due course.
-
- The idea is to mark places where overflows can occur, using macros
- that simply cast to unsigned integers, because overflow arithmetic
- is well defined in this case. Doing so suppresses run-time errors
- of sanitizers without adding computational overhead.

- warning because the macro itself uses `double' literals).

- [smooth] Implement minimal dynamic padding for LCD filtering.
-
- Extra bitmap padding for LCD filtering depends on the filter. The
- default 5-tap filter needs 2 extra subpixels. The light 3-tap filter
- needs only 1 extra subpixel. This space could be already available
- due to rounding. In order to optimize the padding, we now expand
- CBox for the given filter weights before rounding.

- [truetype] Make `IUP' gvar deltas do the same as Apple (#50832).
-
- When points are not touched by gvar interpolation deltas, FreeType
- gave a slightly different result than Apple's CoreText.
-
- The OpenType working group will update the specification to document
- the following behaviour: If the two points with deltas to the `left'
- and `right' of the untouched point have the same coordinate, then
- the inferred delta for the untouched point should be zero.

-
- Add new `slight' auto-hinting mode.
-
- This mode uses fractional advance widths and doesn't scale glyphs
- horizontally, only applying vertical scaling and hinting.
-
- At the same time, the behaviour of the `light' auto-hinter gets
- restored for backward compatibility: Both vertical and horizontal
- scaling is again based on rounded metrics values (this was changed
- in a commit from 2017-03-30 as a side effect). To be more precise,
- the behaviour is restored for TrueType fonts only; for other font
- formats like Type 1, this is a new feature of the `light' hinting
- mode.
-
- * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
- (FT_RENDER_MODE_SLIGHT): New render mode.

- [autofit] Prevent overlapping blue zones.
-
- Problem reported as
-
- https://github.com/google/fonts/issues/632
-
- The font in question (Nunito) has values 705 and 713 for the
- reference and overshoot values, respectively, of the first blue
- zone. Blue zone 2, however, has value 710 for both the reference
- and overshoot. At 12ppem, reference and overshoot of blue zone 0
- becomes 8px, while blue zone 2 becomes 9px.
-
- A peculiarity of this font is that the tops of isolated vertical
- stems like `N' have a slight overshoot also. The auto-hinter tries
- to find the nearest blue zone using the *original* coordinates. For
- vertical stems, this is value 713. For normal horizontal tops like
- in character `E', this is value 710. Since value 713 is mapped to
- 8px but value 710 to 9px, `N' and similar characters are one pixel
- higher than `E', which looks very bad.
-
- This commit sanitizes blue zones to avoid such a behaviour.
-
- * src/autofit/aflatin.c (af_latin_sort_blue): New function.

- [autofit] Use better blue zone characters for lowercase latin.
-
- The number of lowercase characters for computing the top flat blue
- zone value was too small (in most cases only `x' and `z'). If one
- of the two characters has a large serif, say, it can happen that
- FreeType must select between two different values, having a 50%

+
+ [base] Remove a check for resource ID in the resource fork driver.
+
+ LastResort.dfont has a marginal resource ID 0xFFFF for sfnt
+ resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs'
+ (1-46), tells that some IDs are reserved and should not be used.
+ FreeType2 just uses resource ID to sort the fragmented resource.
+ To accept the marginal fonts, the checking is removed.
+
+ * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id
+ validity check, fix a trace message format.
+
+2017-09-08 suzuki toshiya <[email protected]>
+
+ [sfnt, truetype] Register the tags for marginal fonts.
+
+ The first 32bit of standard TrueType variants is 0x00010000,
+ `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
+ OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
+ starting 0xA5 followed by `kbd' or `lst'. Considering the following
+ data could be parsed as conventional TrueType fonts, the header
+ checking is updated to allow these tags. It seems that recent Mac
+ OS X has already switched to normal TTF for these fonts.
+
+ See the discussion at
+ http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
+
+ * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header

+ * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource

+ format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
+
+2017-09-05 Werner Lemberg <[email protected]>
+
+ Fix multiple calls of `FT_Bitmap_Convert'.
+
+ The documentation of `FT_Bitmap_Convert' says that multiple calls do
+ proper reallocation of the target FT_Bitmap object. However, this
+ failed for the sequence
+
+ non-empty bitmap
+ empty bitmap
+ non-empty bitmap
+
+ Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
+ buffer if it became too small; it didn't make the buffer smaller.
+ For an empty bitmap following a non-empty one, only the buffer
+ dimension got set to zero, without deallocation. If the next call
+ was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
+ triggered.
+
+ * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
+ buffer to the correct size.
+
+ * docs/CHANGES: Document it.
+
+2017-09-05 Werner Lemberg <[email protected]>
+
+ [bdf] Fix size and resolution handling.
+
+ * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if
+ `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are
+ missing.
+
+ * docs/CHANGES: Document it.
+
+2017-08-25 Alexei Podtelezhnikov <[email protected]>

+
+ [sfnt] Fix clang compilation (#51788).
+
+ * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of
+ scalars.
+ (vector_shuffle): New macro to take care of a different built-in

+
+2017-08-22 Werner Lemberg <[email protected]>
+
+ [base] Don't zero out allocated memory twice (#51816).
+
+ Patch applied from bug report.
+
+ * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to

+
+ * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.
+
+2017-08-15 Behdad Esfahbod <[email protected]>
+
+ [sfnt] Speed up PNG image loading.
+
+ This reduces the overhead of `premultiply_data' by 60%.
+
+ * src/sfnt/pngshim.c (premultiply_data): Provide code which uses
+ gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a
+ time.
+
+2017-08-11 Werner Lemberg <[email protected]>
+
+ [sfnt, truetype] Improve handling of missing sbits.
+
+ Requested by Behdad.
+
+ Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
+ entries in the bitmap strike(s) for empty glyphs. Instead, they
+ rely that a space glyph gets created from the font's metrics data.
+ This commit makes FreeType behave accordingly.
+
+ * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
+ code.
+
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
+ to make a distinction between a missing bitmap in a composite and a
+ simple missing bitmap.
+
+ * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
+ bitmap-only font), synthesize an empty bitmap glyph if metrics are
+ available.
+
+2017-08-10 Werner Lemberg <[email protected]>
+
+ [base] Minor API improvement for default variation axis setting.
+
+ * src/base/ftmm.c (FT_Set_MM_Design_Coordinates,
+ FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,
+ FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0.
+
+ * docs/CHANGES: Updated.
+
+2017-08-08 Werner Lemberg <[email protected]>
+
+ [psnames] Really fix issue #49949.
+
+ We now use a separate preprocessor macro to handle both definition
+ and declaration of the glyph name arrays.
+
+ * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.
+
+ * src/tools/glnames.py (StringTable::dump,
+ StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.
+ (dump_encoding): Ditto.
+ (main): Use `wb' mode for writing the output file, which works on
+ Windows also.
+
+ * src/psnames/pstables.h: Regenerated.
+
+2017-08-08 Alexei Podtelezhnikov <[email protected]>
+
+ [smooth] Harmony LCD rendering.
+
+ This is a new technology for LCD-optimized rendering. It capitalizes
+ on the fact that each color channel grid is shifted by a third of a
+ pixel. Therefore it is logical to render 3 separate monochrome
+ bitmaps shifting the outline by 1/3 pixel, and then combine them.
+ Importantly, the resulting output does not require additional LCD
+ filtering.
+
+ * src/smooth/ftsmooth.c (ft_smooth_render_generic)
+ [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
+ rendering.
+
+ * include/freetype/ftlcdfil.h, include/freetype/freetype.h,
+ include/freetype/config/ftoption.h, devel/ftoption.h: Updated
+ documentation.
+
+2017-08-08 Alexei Podtelezhnikov <[email protected]>
+
+ * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.
+
+2017-08-08 Alexei Podtelezhnikov <[email protected]>

+
+ * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG.
+
+2017-08-05 Werner Lemberg <[email protected]>
+
+ [base, truetype] New function `FT_Get_Var_Axis_Flags'.
+
+ The reserved `flags' field got a value in OpenType version 1.8.2;
+ unfortunately, the public `FT_Var_Axis' structure misses the
+ corresponding element. Since we can't add a new field, we add an
+ access function.
+
+ * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.
+
+ * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.
+ Updated.
+
+ * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory
+ of `mmvar' to hold axis flags.
+ Fill the axis flags array.
+
+ * docs/CHANGES: Updated.
+
+2017-08-03 Nikolaus Waxweiler <[email protected]>
+
+ [truetype] Fix metrics of B/W hinting in v40 mode.
+
+ Phantom points are now saved outside v40 backwards compatibility
+ mode. This fixes the jumping glyphs when switching between v35 and
+ v40 monochrome mode.
+
+ * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.
+
+2017-08-03 Nikolaus Waxweiler <[email protected]>
+
+ [truetype] Do not set any ClearType flags in v40 monochrome mode.
+
+ This fixes weird behavior of instructions that resulted in rendering
+ differences between v35 and v40 in monochrome mode, e.g., in
+ `timesbi.ttf'.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO)
+ [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check
+ `subpixel_hinting_lean'.
+
+2017-08-01 Werner Lemberg <[email protected]>
+
+ * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
+
+2017-08-01 Behdad Esfahbod <[email protected]>
+
+ [truetype] Fix loading of named instances.
+
+ * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position
+ while loading the `avar' table.
+
+2017-08-01 Werner Lemberg <[email protected]>
+
+ [sfnt, truetype] Minor adjustments for OpenType 1.8.2.
+
+ * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now
+ (tighter) limits.
+
+ * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType
+ version explicitly allows all negative values for the number of
+ contours if we have a composite glyph (this is for better backwards
+ compatibility I guess), but it still recommends value -1.

+
+ Handle some integer overflow run-time errors (#46149, #48979).
+
+ This commit (mainly for 32bit CPUs) is the first of a series of
+ similar commits to handle known integer overflows. Basically, all
+ of them are harmless, since they affect rendering of glyphs only,
+ not posing security threats. It is expected that fuzzying will show
+ up more overflows, to be fixed in due course.
+
+ The idea is to mark places where overflows can occur, using macros
+ that simply cast to unsigned integers, because overflow arithmetic
+ is well defined in this case. Doing so suppresses run-time errors
+ of sanitizers without adding computational overhead.

+ [smooth] Implement minimal dynamic padding for LCD filtering.

+ Add new `slight' auto-hinting mode.

+ This mode uses fractional advance widths and doesn't scale glyphs

+ restored for backward compatibility: Both vertical and horizontal
+ scaling is again based on rounded metrics values (this was changed
+ in a commit from 2017-03-30 as a side effect). To be more precise,
+ the behaviour is restored for TrueType fonts only; for other font
+ formats like Type 1, this is a new feature of the `light' hinting
+ mode.

+ [autofit] Prevent overlapping blue zones.
+
+ Problem reported as
+
+ https://github.com/google/fonts/issues/632
+
+ The font in question (Nunito) has values 705 and 713 for the
+ reference and overshoot values, respectively, of the first blue
+ zone. Blue zone 2, however, has value 710 for both the reference
+ and overshoot. At 12ppem, reference and overshoot of blue zone 0
+ becomes 8px, while blue zone 2 becomes 9px.
+
+ A peculiarity of this font is that the tops of isolated vertical
+ stems like `N' have a slight overshoot also. The auto-hinter tries
+ to find the nearest blue zone using the *original* coordinates. For
+ vertical stems, this is value 713. For normal horizontal tops like
+ in character `E', this is value 710. Since value 713 is mapped to
+ 8px but value 710 to 9px, `N' and similar characters are one pixel
+ higher than `E', which looks very bad.
+
+ This commit sanitizes blue zones to avoid such a behaviour.
