Color Descriptor

Draw regions store color information in a color descriptor:



 
typedef struct TQ3XColorDescriptor {

    unsigned long       redShift;

    unsigned long       redMask;

    unsigned long       greenShift;

    unsigned long       greenMask;

    unsigned long       blueShift;

    unsigned long       blueMask;

    unsigned long       alphaShift;

    unsigned long       alphaMask;

} TQ3XColorDescriptor;
