Dave Arnold 010e0614 2016-12-15T11:22:15 [cff] Implement dynamic stack size for Adobe engine. This also adds `cf2_stack_setReal' and `cf2_stack_pop', needed for the forthcoming CFF2 support. * src/cff/cf2stack.c (cf2_stack_init): Add argument for stack size. (cf2_stack_free): Deallocate stack. (cf2_stack_count, cf2_stack_pushInt, cf2_stack_pushFixed, cf2_stack_popInt, cf2_stack_popFixed, cf2_stack_getReal, cf2_stack_clear): Updated. (cf2_stack_setReal, cf2_stack_pop): New functions. * src/cff/cf2stack.h (CF2_Stack): Add `stackSize' member. Update function declarations. * src/cff/cf2intrp.c (cf2_interpT2CharString): Updated. * src/cff/cffparse.c (cff_parser_init): Add parameter for stack size; return error code. (cff_parser_done): New function. (cff_parser_run): Updated. * src/cff/cffparse.h (CFF_Parser): Add `stackSize' member and make `stack' a pointer. Update function declarations. * src/cff/cffload.c (cff_load_private_dict, cff_subfont_load): Updated.
Werner Lemberg 3ebfe3c5 2016-09-05T10:55:07 [cff] Fix memory initialization. * src/cff/cf2stack.c (cf2_stack_init): Use `FT_NEW'. The `Q' variants of FreeType's memory allocation macros don't do zeroing.
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.
