COPPER

Purpose:

Generates a brownish colormap.

Syntax:

COPPER(len)

len

-

Optional. An integer, the colormap length. Defaults to the length of the current colormap.

Returns:

A table of RGB triples suitable for the SETCOLORMAP function.

Example:

clen = length(getcolormap());

density(ravel(rep(0..(clen-1), 32), clen)');

copper;

creates a table of 32 x N (where N == colormap length) RBG values and displays the resulting colors. The resulting image is a vertical plot of colors ranging from brown (lowest) to white (highest).

Remarks:

copper by itself sets the colormap and shading.

 

a = copper or setcolormap(copper) returns the RGB values. In this case, use SETSHADING to make the new colormap take effect on an existing density or 2D plot.
