 2018-10-08 15:05:36 -07:00
Michiharu Ariza 76e54d2bd8 fixed subroutinized CFF2 flattening 
and some code cleanup

Michiharu Ariza ebeccf3e63 fixed char widths & standard Encoding in subset CFF 
also merged flush_n_args to flush_args into one
takes start index of the arguments on stack instead of count
 2018-09-18 17:24:30 -07:00
Michiharu Ariza c0c85b852d implemented get_glyph_extents with CFF1 
Implemented path operators in a new struct PathProc hooked up to CSOpSet
Added current point to CSInterpEnv
 2018-09-17 11:14:56 -07:00
Michiharu Ariza 5ea03d2951 fix build by untemplatizing DictOpSet & DictVal 
as they aren't instantiated with BlendArg (yet)
 2018-09-04 11:29:15 -07:00
Michiharu Ariza f2d299b0b7 Drop hints from CFF2 charstrings 
Templatized ArgStack so it may store the default value along with blend deltas as BlendArg while parsing blend operator arguments in CFF2 charstring
Added get_region_count() method to VarRegionList & VariationStore
 2018-09-04 10:25:21 -07:00
Michiharu Ariza fcf177885b templatized ArgStack as a prep to store blends 2018-08-31 16:28:47 -07:00

renamed confusing Stack.size to Stack.count

Michiharu Ariza 9fd08cc238 CFF2 subroutine flattner 
Factored out CFF1 & CFF2 common subsetting code in hb-subset-cff-common.hh

Michiharu Ariza 8af9690ac7 Merge branch 'master' into cff-subset

 2018-08-29 13:26:17 -07:00
Michiharu Ariza a11420b48c Subroutine flattener for CFF1 
Subr-flattened charstrings are temporarily re-encoded in ByteStrBuff during "plan" phase, then copied to hb_serialize_context_t during "write" phase

CSOpSet may callback opcode processing "virtual" functions via CRTP

Numer struct may store a value as fixed optionally in addition to int and float
 2018-08-29 12:14:30 -07:00
Michiharu Ariza cef75ea41a Added CFF2 Subr nullifier 
along with CFF2 charstring interpreter
