Alexei Podtelezhnikov f4a3255d45 [unix] Use -fvisibility=hidden.
It is now widely recommended that ELF shared libraries hide symbols
except those with explicit __attribute__((visibility("default"))).
This is supported by all major compilers and should rather be an
option in libtool.

* builds/unix/configure.raw: Add -fvisibility=hidden to CFLAGS.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h (FT_EXPORT): Use visibility
attribute.

attributes with _DLL and FT2_DLLIMPORT.

Werner Lemberg 3758aed760 Add `FT_Done_MM_Var'.
This is necessary in case the application's memory routines differ

and define.

Werner Lemberg 8f4851997b [unix] Install a massaged `ftoption.h' file (#51780).
* builds/unix/configure.raw (ftoption_set, ftoption_unset): New
auxiliary functions to construct...
(FTOPTION_H_SED): ... this new variable.
Apply it as a sed argument while copying `ftoption.h' to the
`builds/unix' directory (using `AC_CONFIG_FILES').
Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted
it immediately afterwards); without this change, it can happen on my
GNU/Linux box that `configure's execution of `config.status' doesn't
create `ftoption.h' (no idea why this happens).

* builds/unix/install.mk (install): Install
`builds/unix/ftoption.h'.

* builds/unix/unix-def.in (DISTCLEAN): Updated.

* builds/unix/.gitignore: Updated.

Ewald Hew b9bd2d14e2 [psaux] Fix CFF advance widths. (#52466)
Glyph advance widths were being written to the new `PS_Decoder' but not
saved to the underlying format specific decoder. This caused pure CFF
fonts to have bad advance width.

* include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width'
field to pointer.
Remove unused fields.
* src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy
to reference.
Remove unused.
* src/psaux/psft.c (cf2_setGlyphWidth): Update code.

Ewald Hew dff40d03df Add T1_CONFIG_OPTION_OLD_ENGINE configuration option.
This controls whether the old Type 1 engine gets compiled into FreeType.
It is disabled by default.

* devel/ftoption.h, include/freetype/config/ftoption.h
(T1_CONFIG_OPTION_OLD_ENGINE): New macro.

* include/freetype/internal/psaux.h (PS_Decoder): Remove unused field.

src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround
relevant code with macro.
Minor code changes.
2017-10-12 18:32:50 +08:00
Ewald Hew 78df3c27b6 Extract width parsing from Type 1 parser.
Duplicate the fast advance width calculations from the old parser. This
is to facilitate adding options for compiling out the old parser.

* include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry

Werner Lemberg 7bfcaacaf5 [sfnt] Adjust behaviour of PS font names for variation fonts.
* src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Use a named instance's
PS name only if no variation is applied.
2017-10-07 13:14:38 +02:00
Werner Lemberg f89c67f043 [cff, truetype] Adjust behaviour of named instances.
This commit completely separates the interaction between named
instances and variation functions.  In particular, resetting the
variation returns to the current named instance (if set) and not to
the base font.

As a side effect, variation functions no longer change the named
instance index.

* src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance'
function.
Also apply `MVAR' table to named instances.

* src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast.
(tt_set_mm_blend): No longer check whether requested variation
coincides with a named instance.
(TT_Set_Var_Design): Use current named instance for default
coordinates.
* src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.
2017-10-07 13:10:53 +02:00
Werner Lemberg 8c92f7622c Make `FT_FACE_FLAG_VARIATION' work.
* include/freetype/internal/tttypes.h (TT_Face): Remove
`is_default_instance'; this can be replaced with a combination of
`FT_IS_VARIATION' and `FT_IS_INSTANCE'.

* src/cff/cffdrivr.c (cff_get_advances): Updated.

* src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/sfobjs.c
(sfnt_init_face): Updated.

(TT_Process_Simple_Glyph, load_truetype_glyph, IS_DEFAULT_INSTANCE),
src/truetype/ttgxvar.c (tt_set_mm_blend): Updated.
* src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design):
Handle `FT_FACE_FLAG_VARIATION'.

* src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design): Handle
`FT_FACE_FLAG_VARIATION'.
2017-10-07 12:12:49 +02:00

2017-10-07 11:25:04 +02:00
John Tytgat 1df35d94c7 [cff] Add support for `FSType'.
* include/freetype/internal/cfftypes.h (CFF_FontRec): Add
`font_extra' entry.

* src/cff/cffdrivr.c (cff_ps_get_font_extra): New function to
retrieve FSType info from the embedded PostScript data.
(cff_service_ps_info): Register function.

* include/freetype/freetype.h (FT_GlyphSlotRec): Document the change.
2017-09-29 00:13:19 -04:00
Alexei Podtelezhnikov 61d1818b5e Bitmap metrics presetting [1/2].
This mainly just extracts the code for presetting the bitmap metrics
from the monochrome, grayscale, and LCD renderers into a separate
function.

* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that
calculates prespective bitmap metrics for the given rendering mode.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Declare it.

* src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds
padding to CBox taking into account pecularities of LCD rendering.
* include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it.

* src/raster/ftrend1.c (ft_raster1_render): Reworked to use
`ft_glyphslot_preset_bitmap'.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
(ft_smooth_render_lcd, ft_smooth_render_lcd): The pixel_mode setting
is moved to `ft_glyphslot_preset_bitmap'.

notice for `SubFont' in Type 1 mode.

Ewald Hew ebb1735aa7 Move `psdecode' into `psobjs'.
As the former only contains a single procedure, move it into
`psobjs' for simplicity.  Also change the parameter order to the
conventional one.

* src/psaux/psdecode.c (ps_decoder_init): Moved to...
* src/psaux/psobjs.c: ...Here.
* src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto.

Ewald Hew 93e3cffddf Change subfont synthesis for CID fonts.
Change `t1_make_subfont' to take in the Private dict record as an
argument.  This is because Type 1 and CID font records in FreeType
have this in different places.

* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
`FT_Face' so that CID is also accepted.
Take `PS_Private' as an argument and let caller figure out where the
Private dict actually is.
Update references.

* include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update
declaration.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update
call.
2017-09-25 09:26:59 +02:00
Ewald Hew 6eb03f8f5a Add missing objects (2/2).
Synthesize a `SubFont' object for Type 1 fonts.  This is used in the
interpreter to access Private dict data, which are stored in
different places for Type 1 and CFF.  This allows the same data to
be used in either mode.

* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
required values to a dummy `CFF_SubFont' object.  This is similar to
`cff_make_private_dict'.
* src/psaux/psobjs.h: Add the new declaration.

* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto.
Add this to the PSAux Service for future use with CID fonts.

* src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H.
(T1_Parse_Glyph_And_Get_Char_String): Add the call.
2017-09-25 09:26:59 +02:00
Ewald Hew cb3f4c610d Add missing objects for Type 1 (1/2).
Move `CF2_Font' instance to `PS_Decoder'.  This is the context for
the interpreter and since it is currently stored in `CFF_Font', is
unavailable in Type 1 mode.

* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New
`cf2_instance' field.

* src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to
`PS_Decoder'.

* src/psaux/t1decode.c (t1_decoder_done): Add finalization code.

* src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses.
2017-09-25 09:26:59 +02:00
Ewald Hew 7e185dcd79 Allow `type1' module to use the Adobe engine.
Add the callback and some conditionals to switch between the two
engines.
