Document

Constructs an IndexColorModel from an array of ints where each int is comprised of red, green, blue, and optional alpha components in the default RGB color model format.

Usage

From source file:ConvertUtil.java

/**
 * Converts the source image to 4-bit colour using the given colour map. No
 * transparency./* ww  w  .  j a  v a  2s . co m*/
 * 
 * @param src
 *            the source image to convert
 * @param cmap
 *            the colour map, which should contain no more than 16 entries
 *            The entries are in the form RRGGBB (hex).
 * @return a copy of the source image with a 4-bit colour depth, with the
 *         custom colour pallette
