-2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [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 <mpsuzuki@hiroshima-u.ac.jp>
-
- [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

- format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
-
-2017-09-05 Werner Lemberg <wl@gnu.org>
-
- 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 <wl@gnu.org>
-
- [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 <apodtele@gmail.com>

- scalars.
- (vector_shuffle): New macro to take care of a different built-in

-
- Patch applied from bug report.

-
- [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 <wl@gnu.org>
-
- [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 <wl@gnu.org>
-
- [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 <wl@gnu.org>
-
- [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 <apodtele@gmail.com>
-
- [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 <apodtele@gmail.com>

-
-2017-08-05 Werner Lemberg <wl@gnu.org>
-
- [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.

-
-2017-08-03 Nikolaus Waxweiler <madigens@gmail.com>
-
- [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 <madigens@gmail.com>
-
- [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 <wl@gnu.org>
-
- * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.

- while loading the `avar' table.
-
-2017-08-01 Werner Lemberg <wl@gnu.org>
-
- [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.
-
- * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add

- [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.

- [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%
- chance to use the wrong one. As a result, rendering at larger PPEM
- values could yield uneven lowercase glyph heights.

- [gzip] Improve building with external zlib (#49673).
-
- Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
- the following error.
-
- ftgzip.c
- zlib-1.2.8\zlib.h(86): error C2061:
- syntax error: identifier 'z_const'
- zlib-1.2.8\zlib.h(94): error C2054:
- expected '(' to follow 'z_const'
- zlib-1.2.8\zlib.h(94): error C2085:
- 'msg': not in formal parameter list
- ...
- zlib-1.2.8\zlib.h(877): fatal error C1003:
- error count exceeds 100; stopping compilation
-
- The error happens because FreeType keeps an own copy of zlib-1.1.4
- under `src/gzip'. When building `src/gzip/ftgzip.c' with
- FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
-
- #include <zlib.h>
-
- which correctly finds an external `zlib.h', but `zlib.h' itself has
- a line
-
- #include "zconf.h"
-
- which makes Visual Studio 2015 find `src/gzip/zconf.h' while
- compiling the files in `src/gzip'.
-
- * src/gzip/zconf.h: Rename to...
- * src/gzip/ftzconf.h: ... this.
- * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

-
- It's unavoidable to call the PNG engine, but to get the metrics it

- allocation of the glyph slot.
- * src/sfnt/pngshim.h: Updated.

-
- Introduce a way of quickly retrieving (embedded) bitmap metrics.
-
- `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
- until the user calls `FT_Render_Glyph'. However, it always
- allocates memory for bitmaps and copies or decodes the contents of a
- bitmap glyph, which can be quite slow for PNG data.
-
- * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New

-
- [pcf] Enrich family name with foundry name and glyph width info.
-
- This is a very old patch from openSuSE (from 2006, submitted to
- FreeType in 2011) that I forgot to apply.
-
- https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
-
- Prepend the foundry name plus a space to the family name. There are
- many fonts just called `Fixed' which look completely different, and
- which have nothing to do with each other. When selecting `Fixed' in
- KDE or Gnome one gets results that appear rather random, the style
- changes often if one changes the size and one cannot select some
- fonts at all.
-
- We also check whether we have `wide' characters; all put together,
- we get family names like `Sony Fixed' or `Misc Fixed Wide'.
-
- * src/pcf/pcfread.c (pcf_load_font): Implement it.
-
- * docs/CHANGES: Document it.

-
- * docs/CHANGES: Updated.
-
-2016-09-25 Werner Lemberg <wl@gnu.org>
-
- [truetype] Sanitize only last entry of `loca' table.
-
- Without this patch, a loca sequence like `0 100000 0 100000 ...',
- where value 100000 is larger than the `glyf' table size, makes
- FreeType handle the whole `glyf' table as a single glyph again and

-
- [smooth] Simplify span rendering more.
-
- It turns out that there is significant cost associated with `FT_Span'
- creation and calls to `gray_render_span' because it happens so
- frequently. This removes these steps from our internal use but leaves
- it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
- is about 5%.
-
- * src/smooth/ftgrays.c (gray_render_span): Removed. The code is
- migrated to...
- (gray_hline): ... here.
-
-2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [smooth] Streamline pixmap drawing a bit more.
-
- Zero coverage is unlikely (1 out of 256) to warrant checking. This
- gives 0.5% speed improvement in rendering simple glyphs.

-
- [sfnt] Fix `FT_Get_Advance' for bitmap strikes.
-
- `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
- advance value from the font table and then scales it by the
- `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
- set that value for bitmap fonts and the advance gets scaled to zero.

- [sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
-
- Since 2016-05-16 we detect infinite recursion directly.
-
- * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
- `maxComponentDepth'.
- * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
- `maxComponentDepth' is not valid. Instead, simply adjust its value
- and emit a tracing message.

-
- No functional change.

-
- [truetype] Record the end of IDEFs.
-
- To match the logic in FDEF. The value of the end is only used for
- bound-checking in `Ins_JMPR', so it may not have been obvious that
- it was not recorded. Tested (as part of Font Validator 2.0) all the
- fonts on Fedora and did not see any change.
-
- * src/truetype/ttinterp.c (Ins_IDEF): Updated.
-

-
- * src/truetype/ttinterp.c (opcode_name): Updated.
- (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'.
- (TT_RunIns): Updated.
-
-2016-07-17 Werner Lemberg <wl@gnu.org>
-
- [truetype] Add support for Apple's
-
- GETDATA[], opcode 0x92
-
- bytecode instruction. It always returns 17, and we have absolutely
- no idea what it is good for...
-
- * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
- (Ins_GETDATA): New function.
- (TT_RunIns): Add it.
-
-2016-07-16 Werner Lemberg <wl@gnu.org>
-
- [truetype] Add bytecode support for GX variation fonts.
-
- This commit implements undocumented (but confirmed) stuff from
- Apple's old bytecode engine.
-
- GETVARIATION[], opcode 0x91
- This opcode pushes normalized variation coordinates for all axes
- onto the stack (in 2.14 format). Coordinate of first axis gets
- pushed first.
-
- GETINFO[], selector bit 3
- If GX variation support is enabled, bit 10 of the result is set
- to 1.
-
- * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
- (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
- (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
- bit 3, checking support for variation glyph hinting.
- (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
- to implement opcode 0x91.
- (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
-
-2016-07-16 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix GETINFO bytecode instruction.
-
- * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for
- stretching information.
-
-2016-07-16 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] Make all glyphs in `Zycon' GX font work.
-
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
- tests.
-
-2016-07-16 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix GX delta tracing.
-
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
- relative point movements.
-
-2016-07-16 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] More fixes for GX.
-
- This finally fixes the rendering of the cyclist and the lizard in
- the `Zycon' font.
-
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
- index is always cumulative.
-
- (tt_handle_deltas): Rename to...
- (tt_interpolate_deltas): ... This.
- Add new parameter for output point array.
- Update caller.
-
- (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
- the intermediate results of `tt_interpolate_deltas' that are to be
- added to `outline->points'.
-
-2016-07-15 Werner Lemberg <wl@gnu.org>
-
- * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
-
- `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.
-
- Reported by Alexei.
-
-2016-07-16 Nikolaus Waxweiler <madigens@gmail.com>
-
- * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.
-
- Problem reported by Hin-Tak Leung.
-
-2016-07-15 Werner Lemberg <wl@gnu.org>
-
- [autofit] Update and improve segment and edge tracing.
-
- * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
- `delta' also.
- Don't show first point of segment as a replacement for `pos'; this
- is (a) misleading, since the difference to `pos' can be almost
- arbitrarily large in corner cases, and (b) it is better to have all
- segment data in font units instead of a single value given in output
- space coordinates.
- Improve layout.
- (af_glyph_hints_dump_edges): Show px->units and units->px conversion
- values for convenience.
- Improve layout.
-
-2016-07-15 Werner Lemberg <wl@gnu.org>
-
- [autofit] For edges, reject segments wider than 1px (#41334).
-
- * src/autofit/afhints.h (AF_SegmentRec): New member `delta'.
-
- * src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute
- `delta'.
- (af_latin_hints_compute_edges): Reject segments with a delta larger
- than 0.5px.
-
-2016-07-14 Werner Lemberg <wl@gnu.org>
-
- * include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.
-
-2016-07-14 Werner Lemberg <wl@gnu.org>
-
- [sfnt] Fix `face_index' value in `FT_Face' for named instances.
-
- * src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits.
-
-2016-07-14 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
-
-2016-07-14 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] Fix gxvar delta interpolation.
-
- The coordinates of the base font should be used for interpolation
- purposes, NOT the current points (i.e., the result of accumulation
- of previous deltas).
-
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
- `points_org' before looping over all tuples.
