The GREPLAY Procedure

Creating Color Maps

Color maps are useful for assigning unavailable colors on your current device to your graph. A color map is a list of up to 256 pairs of colors. By mapping the original colors to a different list of colors, you can change the colors in your graphics output.

To create a color map named CLRMAP, perform the following actions:

Start the GREPLAY procedure with the NOFS option.
Assign a color map catalog with the CC= option.
Define the output catalog with the GOUT= option.
Define a color map with the CDEF statement.
Remap your colors.
End the GREPLAY procedure with the QUIT statement.

Before you create a color map, you must assign a color map catalog. The following example defines a color map named CLRMAP:

proc greplay cc=clrmap gout=work nofs;
   cdef clrmap 1 / cyan : blue;
quit;

When you assign a color map and replay graphics output the following occurs:

The stored GRSEG entry or entries, retain the original foreground colors.
The colors used to replay the graphics are not saved with the original graphics output.
Graphics output is not created when you replay graphics output using a color map.
