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;
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.
