Alexei Podtelezhnikov 884e4e67ee [base] Implement fast vector normalization.
The function uses Newton's iterations instead of dividing vector
components by its length, which needs a square root. This is,
literally, a bit less accurate but a lot faster.

Werner Lemberg 7cdc77f229 * CMakeLists.txt: Always create `ftconfig.h'.
For non-UNIX builds, the file stays unmodified.  However, it's
better to have the main configuration files at the same place
regardless of the OS.

Werner Lemberg 8502c98b15 Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include).  After this commit, only `ft2build.h' stays in
the compiler's include path.

No visible changes for the user who follows the standard FreeType
header inclusion rules.

* include/*: Move to ...
* include/freetype2/*: This directory, except `ft2build.h'.

* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/install.mk (install, uninstall),
builds/unix/freetype2.in: Updated.

* builds/unix/freetype-config.in: Updated.
Emit -I directory only if it is not `/usr/include'.

* devel/ft2build.h, include/ft2build.h: Updated.

* include/freetype2/config/ftheader.h,
include/freetype2/internal/ftserv.h,

macros.

* src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated.

* docs/*: Updated.

Werner Lemberg 31d97df99f Make Jam support work again.
This is just very basic stuff and just a little bit tested on
GNU/Linux only.  I won't delve into this since I'm not a Jam user.

* Jamfile: Call `HDRMACRO' for `ftserv.h' also.
(DEFINES): Replace with...
(CCFLAGS): ... this.

* src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is
already handled in the top-level Jamfile.

* src/autofit/Jamfile (DEFINES): Replace with...
(CCFLAGS): ... this.
(_sources): Add missing files.

* src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no
longer contains macro header definitions.

* src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile,
src/truetype/Jamfile (_sources): Add missing files.

Werner Lemberg 75534a0432 [truetype] Fix memory leak.
Problem reported by Grissiom <chaos.proton@gmail.com>; in

  http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html

there is an example code to trigger the bug.

* src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
data before allocating again.  Bug most probably introduced four
years ago in version 2.4.3.

(TT_RunIns): Implement display of code position and stack.

Werner Lemberg 764ddcc164 Update `CHANGES' file. 2015-05-31 12:32:11 +02:00
Werner Lemberg e9df4e47e3 [truetype] In GX, make private point numbers work correctly.
This is completely missing in Apple's documentation: If a `gvar'
tuple uses private point numbers (this is, deltas are specified for
some points only), the uncovered points must be interpolated for
this tuple similar to the IUP bytecode instruction.  Examples that
need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.

* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
tt_handle_deltas): New functions.
(TT_Vary_Get_Glyph_Deltas): Renamed to...
(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
points and does no longer return an array of deltas.
Add tracing information.
Call `tt_handle_deltas' to interpolate missing deltas.
Also fix a minor memory leak in case of error.

* src/truetype/ttgxvar.h: Updated.

* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Updated.
2015-05-31 12:21:34 +02:00
Werner Lemberg 9845c1d4e9 [truetype] In GX, make intermediate tuplets work at extrema.
* src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.

Werner Lemberg cdee7d1423 [truetype] Add tracing information to GX code.
* src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
TT_Set_Var_Design, tt_face_vary_cvt): Do it.

Werner Lemberg a5e1f6f39b [truetype] Fix commit from 2015-05-22.
* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code

Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
2015-05-24 23:29:23 +02:00
Werner Lemberg 7f0994820b [truetype] Fix return values of GETINFO bytecode instruction.
* src/truetype/ttinterp.h (TT_ExecContextRec): New fields
`vertical_lcd' and `gray_cleartype'.

* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
Change `symmetrical smoothing' to TRUE, since FreeType produces
exactly this.

* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
values for symmetrical smoothing, namely 11/18.
Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
(12/19).

Werner Lemberg bb435da213 [truetype] Minor.
* src/truetype/ttinterp.h (TT_ExecContext):
 s/subpixel/subpixel_hinting.

* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
2015-05-23 07:21:25 +02:00
Werner Lemberg c61cad868b [truetype] Support selector index 3 of the INSTCTRL instruction.
This flag activates `native ClearType hinting', disabling backwards
compatibility mode as described in Greg Hitchcocks whitepaper.  In
other words, it enables unrestricted functionality of all TrueType
instructions in ClearType.

* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
unconditionally.
(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
`GS.instruct_control' is active.

* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
(Ins_GETINFO): Updated.

* docs/CHANGES: Document it.

Werner Lemberg 790b8dfbff [truetype] Minor. 2015-05-20 12:33:40 +02:00
Werner Lemberg 0a6b6ff7c6 [truetype] Fix loading of composite glyphs.
* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
ARGS_ARE_XY_VALUES flag is not set, handle argument values as
unsigned.  I trust `ttx' (which has exactly such code) that it does
the right thing here...

The reason that noone has ever noticed this bug is probably the fact
that point-aligned subglyphs are rare, as are subglyphs with a
number of points in the range [128;255], which is quite large (or
even in the range [32768;65535], which is extremely unlikely).
2015-05-17 22:54:48 +02:00
Chris Liddell a87fb8ccf3 [cff] Make the `*curveto' operators more tolerant.
* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
pulling values off the stack until the stack is exhausted.
Implicitly the stack must be a multiple (or for subtly different
behaviour) a multiple plus a specific number of extra values deep.
If that's not the case, enforce it (as the old code did).
2015-05-12 07:27:35 +02:00
Chris Liddell d65bf72c3e [cff] fix incremental interface with new cff code.
* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
interface to retrieve glyph data for a SEAC, it be left to the
incremental interface callback to apply the encoding to raw
character index (as it was in the previous code).
2015-05-12 07:16:46 +02:00
Alexei Podtelezhnikov 4091495271 [autofit] Speed up IUP.
* src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
