ABSTRACT:
A graphics data processing apparatus having graphic image operations on two images. Two graphic images are formed into a single combined image based upon a predetermined combination of the multibit color codes representing corresponding pixels of the two images. A transparent color code is permitted for the first of the graphic images. The combination of a transparent color code from the first graphic image with any color code from the second graphic image yields the color code of the second graphic image. This innovation enables the use of color codes having selectable numbers of bits set by the number stored in a pixel size register. In particular the transparent color code, which is detected by a transparent color code detection device independent of the image operation, has a selectable number of bits set by the pixel size register in a manner like any other color code. This enables the same graphics data processing apparatus to be applicable to a wide variety of applications having images using differing lengths of color codes while preserving the transparency function.
