ABSTRACT:
The method of the invention performs logical operation on a pixel image, wherein pixels of the image comprise multi-bit color pixel values. The method performs the steps of: identifying a received image as an image type other than a raster image; and if such identified image type consists of fully saturated multi-bit color pixel values, performing logical combination operations on the multi-bit color pixel values through use of binary logical operators. If the received image is identified as including other than fully saturated multi-bit color pixel values, performing logical combination operations on the multi-bit color pixel values using arithmetic logical operators.
