* include/internal/ftrfork.h (CONST_FT_RFORK_RULE_ARRAY_BEGIN): Fix
generated function name.
* src/base/basepic.c (FT_Init_Table_raccess_guess_table): Rename
to ...
(FT_Init_Table_ft_raccess_guess_table): ... this so that the
function name correctly corresponds to what the macro framework
expects.
* src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so
that PIC functions are compiled also.
This is the first commit of a series to create a new top-level
structure (a `style') for handling scripts, writing_systems, and
soon-to-be-added coverages.
This patch unifies the subpixel and non-subpixel cases.
* src/truetype/ttinterp.h (TT_ExecContextRec): Remove
`grayscale_hinting'; all code should refer to `grayscale' instead.
Remove unused `native_hinting' member.
Rename `subpixel_hinting' member to `subpixel.
* src/truetype/ttgload.c (TT_LOADER_SET_PP): Updated.
(tt_loader_init): Updated.
* src/truetype/ttinterp.c (Ins_GETINFO): Simplify.
Updated.
Problem reported by David Kastrup <dak@gnu.org>.
Surprisingly, a description how to do that was completely missing in
the API reference.
* include/freetype.h, include/ftchapters.h: New documentation
section `header_inclusion'.
Problem reported by Nigel Tao <nigeltao@golang.org>.
* src/truetype/ttgload.c (TT_Hint_Glyph): Remove code that shifts
the glyph (component) by a fractional value computed from the LSB
phantom point. This is wrong, since the horizontal phantom points
get rounded horizontally later on.
Greg Hitchcock provided very interesting insights into the
complicated history of the horizontal positions of the TSB and BSB
phantom points.
* src/truetype/ttgload.c (TT_LOADER_SET_PP)
[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
`grayscale_hinting' flags as conditionals for the x position of TSB
and BSB.
This corrects the commit from 2013-11-21. Problem reported by
Andrey Panov <panov@canopus.iacp.dvo.ru>.
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Fix logic to
detect excessive bytes for bit-aligned bitmaps.
This is a further improvement to the changes from 2013-11-06.
* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
are rounded horizontally, vertical ones are rounded vertically.
(TT_LOADER_SET_PP): The horizontal position of vertical phantom
points in pre-ClearType mode is zero, as shown in the OpenType
specification.
Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
`IS_HINTED' clause.
Also remove redundant check using `maxSizeOfInstructions' – in
simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
* src/sfnt/sfobjs.c (sfnt_load_face): Return correct `bsize->width'
value if the font lacks an `OS/2' table.
We are now able to successfully load `AppleMyoungJo.ttf'.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Don't trust glyph
format.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see
http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html
for details.
* src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep'
tables also for setting `autohint'.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from
`TT_Process_Composite_Glyph' for handling unreliable values of
`maxSizeOfInstructions'.
We now follow the `official' announcement from Microsoft (on the
OpenType mailing list, which unfortunately hasn't a public archive).
* include/freetype/tttables.h (TT_OS2):
s/usLowerPointSize/usLowerOpticalPointSize/,
s/usUpperPointSize/usUpperOpticalPointSize/.
* src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct
default values.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level. Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.
Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like
#include <ft2build.h>
#include FT_FREETYPE_H
...
don't need any change to the source code.
* include/freetype/*: Move up to...
* include/*: ... this directory.
* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.
*/*: Essentially do `s@/freetype/@/@' where appropriate.
* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.
Problem reported by Nigel Tao <nigeltao@golang.org>.
This is a follow-up commit to the previous one.
* src/truetype/ttgload.c (load_truetype_glyph): Call
`tt_get_metrics' after loading the glyph header.
This commit also improves the start values of vertical phantom
points. Kudos to Greg Hitchcock for help.
* src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass
`yMax' value. Replace code with fixed Microsoft definition.
(tt_get_metrics): Updated.
(TT_LOADER_SET_PP): Add explanation how to initialize phantom
points, taken from both the OpenType specification and private
communication with Greg (which will eventually be added to the
standard).
Fix horizontal position of `pp3' and `pp4'.
* src/truetype/ttgload.h: Updated.
* src/truetype/ttdriver.c (tt_get_advances): Updated.
* docs/CHANGES: Updated.
Simply apply the patch from the bug report.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: The used #pragma directives only
work with gcc versions 4.6 and higher.
Two benefits: The allocated FDEF (and IDEF) array gets slightly
smaller, and the `ttdebug' demo program has access to function
numbers without additional costs.
Fortunately, no changes to FontForge are necessary – this is the
only external TrueType debugger I know of, but others may exist and
should check the code accordingly.
* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
`Cur_End' with a pointer to the corresponding `TT_DefRecord'
structure.
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,
Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>):
Updated.
See
http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism
for the announcement.
* include/freetype/tttables.h (TT_OS2): Add fields
`usLowerPointSize' and `usUpperPointSize'. Since FreeType returns
this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.
* src/sfnt/ttload.c (tt_face_load_os2): Implement it.
* docs/CHANGES: Updated.
