The TrueType Engine¶

Synopsis¶

This section contains a function used to query the level of TrueType bytecode support compiled in this version of the library.

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	Deprecated and removed.
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).

FT_Get_TrueType_Engine_Type¶

Defined in FT_MODULE_H (freetype/ftmodapi.h).

  FT_EXPORT( FT_TrueTypeEngineType )
  FT_Get_TrueType_Engine_Type( FT_Library  library );

Return an FT_TrueTypeEngineType value to indicate which level of the TrueType virtual machine a given library instance supports.

input

library

A library instance.

return

A value indicating which level is supported.
