FT_TrueTypeEngineType

Defined in FT_MODULE_H (freetype/ftmodapi.h).

  typedef enum  FT_TrueTypeEngineType_
  {
    FT_TRUETYPE_ENGINE_TYPE_NONE = 0,
    FT_TRUETYPE_ENGINE_TYPE_UNPATENTED,
    FT_TRUETYPE_ENGINE_TYPE_PATENTED

  } FT_TrueTypeEngineType;

A list of values describing which kind of TrueType bytecode engine is implemented in a given FT_Library instance. It is used by the FT_Get_TrueType_Engine_Type function.

values

FT_TRUETYPE_ENGINE_TYPE_NONE	The library doesn't implement any kind of bytecode interpreter.
FT_TRUETYPE_ENGINE_TYPE_UNPATENTED	The library implements a bytecode interpreter that doesn't support the patented operations of the TrueType virtual machine. Its main use is to load certain Asian fonts that position and scale glyph components with bytecode instructions. It produces bad output for most other fonts.
FT_TRUETYPE_ENGINE_TYPE_PATENTED	The library implements a bytecode interpreter that covers the full instruction set of the TrueType virtual machine (this was governed by patents until May 2010, hence the name).
