ABSTRACT:
A method, apparatus, and computer instructions for managing color maps in a data processing system. Responsive to a request to add a color map to a color table, a determination is made as to whether the color map is already installed in the color table. If the color map is not already installed in the color table, a decision is made as to whether a free block of color table entries sufficient to hold the color map is present in the color table. A determination is made as to whether existing blocks of color table entries in the color table can be rearranged to form a new free block of color table entries, if the free block of color table entries is insufficient to hold the color map. The existing blocks of color table entries in the color table are rearranged if the existing blocks of color table entries can be rearranged to form the new free block of color table entries. The color map is installed in the new free block of color table entries after the block of color table entries has been formed by rearranging the existing blocks of color table entries.
