Details

Generates a color ramp of RGB colors that fill the RGB color spectrum, given a specified number of red, green, and blue shades to use. This method generates a color map of reds×greens×blues colors, with a maximum of 256 colors allowed. You can generate a color map consisting only of reds, greens, or blues by specifying that only one shade be used for the other two colors.

Example

This example generates a ramp of five shades of green and lists the color map:

   call send(cmap_id, '_generateColorRamp',
             1,5,1);
   call send(cmap_id, '_putCmap');

These lines are written to the Message window:
