Werner Lemberg 950f1696 2016-02-07T11:39:54 [cff] Implement missing operators in new engine (except `random'). * src/cff/cf2font.h (CF2_STORAGE_SIZE): New macro. * src/cff/cf2intrp.c (cf2_interpT2CharString): Implement the following operators: abs, add, and, div, drop, dup, eq, exch, get, ifelse, index, mul, neg, not, or, put, roll, sqrt, sub. * src/cff/cf2stack.h, src/cff/cf2stack.c (cf2_stack_roll): New auxiliary function for `roll' operator.
Werner Lemberg 1a95d002 2016-02-07T00:39:03 Whitespace.
Jered Gray f53bab93 2016-01-10T12:03:36 [cff] Fix usage of `|' operator. * src/cff/cf2intrp.c (cf2_interpT2CharString) [cf2_cmdEXTENDEDNMBR, default]: `|' is not guaranteed to be processed from left to right by the compiler. However, the code repeatedly calls `cf2_buf_readByte' to get the arguments to `|' ... Fix this.
Werner Lemberg f1c93439 2015-10-22T10:11:23 [cff] Avoid overflow/module arithmetic. This modifies the addition of subroutine number to subroutine bias from unsigned to signed, but does not change any results. * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer, cf2_initLocalRegionBuffer): Change variable names from (unsigned) `idx' to (signed) `subrNum', since it is not an index until after the bias is added. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Updated similarly.
Dave Arnold 3cfd5123 2015-10-21T14:07:25 [cff] Fix limit in assert for max hints. * src/cff/cf2interp.c (cf2_hintmask_setAll): Allow mask equal to the limit (96 bits).
Werner Lemberg eb1bba9b 2015-06-30T09:46:39 Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues.
Chris Liddell a87fb8cc 2015-05-12T07:27:35 [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).
Werner Lemberg 8ce30263 2015-03-27T08:33:47 [cff] Trace charstring nesting levels. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLGSUBR, cf2_cmdCALLSUBR, cf2_cmdRETURN>: Implement it. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_callsubr, cff_op_callgsubr, cff_op_return>: Ditto.
