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.
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;
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.
