ColorRamp

class ColorRamp extends AnyRef

* List of colors for rendering a raster.

In order to select colors for a raster, one often divides the values in the raster into distinct ranges and selects a color for each range. A ColorRamp provides the colors from which to select.

NB: The list of colors are RGBA values, which are usually represented as 8 character hex string, like "0x0000FFFF" where the last two character encode an alpha (transparency/opacity) value.

Usually on the web, you see "RGB" or "hex" color values, like 0x0000FF (blue). If you have a list of RGB values, use the method ColorRamp.createWithRGBColors.

    Generate n new colors using the existing color ramp as a guide.

    The first and last colors of the existing ramp will be preserved in the output ColorRamp. For example, given a color ramp of two colors, red and yellow, a request for 5 colors would return Red, Yellowish-Red, Orange, Reddish-Yellow, Yellow.
