Opcode Constants and Data Types

Modified Transform Data Opcodes

A constant from the gxTransformDataOpcode enumeration follows a gxSetDataOpcode operation opcode if transform data follows. The data stream bytes that follow describe one of the attributes specified in this enumeration.

enum  gxTransformDataOpcode{
   gxTransformReservedOpcode,
   gxTransformTagOpcode,
   gxTransformClipOpcode,
   gxTransformMappingOpcode,
   gxTransformPartMaskOpcode,
   gxTransformToleranceOpcode
};
