Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg 0a0c22569d Update copyright year. 2018-01-02 09:33:57 +01:00
Werner Lemberg 98ba0c4a37 New `ftdriver.h' file, covering all driver modules.
This reduces redundancy and increases synergy; it also reduces the
number of header files.

* include/freetype/config/ftheader.h (FT_DRIVER_H): New macro.
(FT_AUTOHINTER_H, FT_CFF_DRIVER_H, FT_TRUETYPE_DRIVER_H,
FT_PCF_DRIVER_H, FT_TYPE1_DRIVER_H): Make them aliases to
FT_DRIVER_H.

* include/freetype/ftautoh.h, include/freetype/ftcffdrv.h,
include/freetype/ftpcfdrv.h, include/freetype/ftt1drv.h,
include/freetype/ftttdrv.h: Replaced with...
* include/freetype/ftdriver.h: ...this new file.
(FT_CFF_HINTING_ADOBE, FT_T1_HINTING_ADOBE): Renamed to...
(FT_HINTING_ADOBE): ... this new macro.
(FT_CFF_HINTING_FREETYPE, FT_T1_HINTING_FREETYPE): Renamed to...
(FT_HINTING_FREETYPE): ... this new macro.

* src/*/*: Updated accordingly.

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.

2017-11-22 12:38:36 +08:00
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.

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.

* include/freetype/internal/psaux.h (PSAux_ServiceRec): Update
`ps_decoder_init' function signature.

2017-09-25 09:26:59 +02:00
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

function declarations.
* src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the
callbacks.

* src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for
number conversion.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code
to choose which renderer to use.

* src/cid/cidgload.c (cid_load_glyph): Update call.
* src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update
includes.
2017-09-25 09:26:59 +02:00
Ewald Hew 645d1b86ad Move and rename `CFF_Driver'.
This is so that we can use the same hinting engine parameters for
Type 1.

* include/freetype/internal/cffotypes.h (CFF_Driver): Rename and
move to...
* include/freetype/internal/psaux.h (PS_Driver): ...here.

* src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c,
src/cff/cffobjs.c, src/cff/cffobjs.h, src/psaux/psft.c,
src/psaux/psobjs.c: Update references.
2017-09-25 09:26:59 +02:00
Ewald Hew d23affe1ef Reorganize object fields.
Make some fields more generic, so that we can access them the same
way regardless of Type 1 or CFF.

* include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face'
to `FT_Face'.
Remove unused fields.

* src/psaux/psft.c: Update all accesses of `PS_Builder.face'.
Add some asserts to guard against casting `T1_Face' as `TT_Face'.

* src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow
`CFF_GlyphSlot', so that we can pretend they are the same in the
interpreter.

* src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point):
Updated with above changes.
2017-09-25 09:26:59 +02:00
Ewald Hew 43c015823f Objects for new interpreter (part 2).
Make the new objects copy over values.  They are essentially wrapper
types for the different decoders/builders.

* include/freetype/internal/psaux.h: Update declarations.
(PS_Builder): Add `is_t1' flag.
(PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to...
(CFF_Decoder_{Get,Free}_Glyph_Callback: ... this.

* src/psaux/psdecode.c, src/psaux/psobjs.c: Implement copy with two
modes.

service.

2017-09-25 09:26:59 +02:00
Ewald Hew b624868b8e Move `cff_random' into `psaux' service.
NOTE: Does not compile!

Minor fix to allow both `cff' and `psaux' to use `cff_random'.

* src/cff/cffload.c (cff_random): Move to...
* src/psaux/psobjs.c: Here.
* src/cff/cffload.h: Move corresponding declaration to
`src/psaux/psobjs.h'.

structure with a single field `module_data'.

* src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of
`FT_Size' structure.

* src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use
`size->internal->module_data' instead of `size->internal'.

This is a purely mechanical conversion.
2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

Werner Lemberg 2ef0a19842 [type1] Fix handling of /FontBBox in MM fonts.
Problem reported by Del Merritt <del@alum.mit.edu>

If we have

              { 41 42 43 44 45 46 47 48 } }

in the /Blend dictionary,  then the first BBox is { 11 21 31 41 },
the second { 12 22 32 42 }, etc.
