Required Arguments

color-map-entry

identifies an existing or new color map. Color-map-entry is the name of a catalog entry.

If the color map name is not in the color map catalog, then the procedure creates a new color map. If the color map name is already in the color map catalog, then the procedure modifies or adds to that color map.

color-number / from-color:to-color

specifies a color pair and how it is defined.

color-number

specifies the number of a color pair.

from-color:to-color

defines the colors that are being mapped:

from-color: is the color to be mapped.
to-color: is the new color that replaces from-color in the replayed graphics output.

DES='entry-description'

specifies a description of the catalog entry for the color map. The maximum length for the entry-description is 40 characters. By default, the GREPLAY procedure assigns a description of **** NEW COLOR MAP **** to the color map.
