Abstract
A method and apparatus, including a computer program product, implementing techniques for creating an indexed-color image from a direct-color image. The techniques include receiving a color lookup table and an associative data structure. The color lookup table comprises an indexed list of direct color values. For each pixel of the indexed-color image, the techniques include performing a lookup operation in the associative data structure to determine whether a corresponding direct color value was previously associated with an index value. If the lookup operation yields a positive result, then the associated index value is used as the pixel value. Otherwise, an entry in the color lookup table is selected for the corresponding direct color value of the pixel, the index value of the selected entry is used as the pixel value, and the index value of the selected entry is associated with the corresponding direct color value in the associative data structure.
