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.

padding to CBox taking into account pecularities of LCD rendering.

`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'.

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/psobjs.c: ...Here.

2017-09-25 09:26:59 +02:00
Ewald Hew d52dd7f31d Fix Type 1 hinting.
Type 1 hinting breaks sometimes when mid-charstring hints should
have been in the initial hintmap.  This fix adds a preprocessing
pass that reads all hints and builds the correct initial hintmap
first, before proceeding to build the glyph outline.

* src/psaux/psintrp.c (cf2_interpT2CharString): New
`initial_map_ready' boolean flag.
Ignore outline commands and hint changes on first pass.
<cf2_cmdENDCHAR>: Add section to build hintmap and rewind.

results.
s/font->decoder/decoder/ where necessary.

offset parameter in `cf2_doStems' instead of doing correction for
left-sidebearing.

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.

implied seac for CFF.

* src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New
function to look up the glyph index.

Ewald Hew d55a701de6 Extend Adobe interpreter (flex in callothersubr).
* src/psaux/psintrp.c (cf2_interpT2CharString)
<cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1,
2).
<cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing
flex.  This is to avoid closing the current contour.
2017-09-25 09:26:59 +02:00
Ewald Hew 9668255965 Extend Adobe interpreter (callothersubr).
* src/psaux/psintrp.c (cf2_interpT2CharString)
<cf2_escCALLOTHERSUBR>: Copy code from
`t1_decoder_parse_charstrings' (in `t1decode.c').

new hints are applied.
Fix function calls and stack access.
2017-09-25 09:26:59 +02:00
Ewald Hew 77c1b331f6 Extend Adobe interpreter (pop).
* src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled
OtherSubr results are stored.  Implement the PostScript stack using
an array.
<cf2_escPOP>: Ensure that the stack is not cleared after getting
`OtherSubr' results.
Fix stack access.
2017-09-25 09:26:59 +02:00

Type 1 mode.

* src/psaux/psft.c (cf2_initLocalRegionBuffer): Add Type 1 mode.
2017-09-25 09:26:59 +02:00
Ewald Hew 4b58c518c9 Extend Adobe interpreter (div, four-byte numbers).
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add
Type 1 mode.  Type 1 requires large integers to be followed by
`div'; cf. `Adobe Type 1 Font Format', section 6.2.
<op == 255>: Push Type 1 four-byte numbers as `Int' always.  This is
to ensure `div' and `callsubr' get values they can use.
2017-09-25 09:26:59 +02:00
Ewald Hew 81b86c459c Extend Adobe interpreter (hstem, vstem, hstem3, vstem3).

cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode.
Allow adding hints mid-charstring.
<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands
for three normal stem hints.  This requires some recalculation of
stem positions.
Correction for left sidebearing.
2017-09-25 09:26:59 +02:00
Ewald Hew e180afa951 Extend Adobe interpreter (hsbw, sbw).

first operation in a Type 1 charstring.
(cf2_interpT2CharString): Remove unused variables.
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'
must be the first operation in a Type 1 charstring.

Ewald Hew 4ed1b98dbd Extend Adobe interpreter (closepath).
* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
Use the right builder function.  We can use the `haveWidth' boolean
already present, instead of implementing `parse_state'.
2017-09-25 09:26:59 +02:00
Ewald Hew 37ed70f628 Add Type 1 operations to Adobe CFF interpreter.
The following Type 1 specific ops have been added (copied from
`t1decode'):

  closepath
  vstem3
  hstem3
  seac
  sbw
  callothersubr
  pop
  setcurrentpoint
  hsbw

The following require a Type 1 mode, because of differences in
specification:

  hstem
  vstem
  vmoveto
  callsubr
  div
  rmoveto
  hmoveto
  Numbers

The subsequent commits will implement these changes and adapt
accesses of data and objects to the new interpreter.

NOTE: Will not compile in the meantime!

* src/psaux/psintrp.c: Add opcodes to enum.
(cf2_interpT2CharString): Copy relevant code over from
`t1_decoder_parse_charstrings' (in `t1decode.c').
2017-09-25 09:26:59 +02:00
Ewald Hew 283ef28505 Fixes for rendering.
The Type 1 advance width calculation passes null for glyph slot,
etc, which can cause null pointer access in the new interpreter.
Fall back to the old one for now.

Fix the large glyph retry code and ensure hinting and scaling flags
are set properly.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a
check for metrics_only.
Set the `force_scaling' flag.
(T1_Parse_Glyph): Updated.

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'.

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

* 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.

Updated with above changes.

Replace the `cf2' file name prefix with `ps' as the Adobe engine
