Abstract
A method, apparatus, and article of manufacture for converting images to an arbitrary palette in a computer. A map table is created from the palette, wherein index entries referencing color values in the palette are stored at nodes in the table having coordinates derived from the referenced color values. For each pixel of an input datastream, the coordinates of the node in the map table representing a color value closest to the color value of the pixel are calculated from the color value for the pixel. An output datastream is created using the color value in the palette referenced by the index entry stored in the node.
