The ColorUtils class

The ColorUtils class provides some handy methods for fast pixel manipulation. The most important methods are getAlpha(int), getRed(int), getGreen(int), getBlue(int) and getARGB(int,int,int,int). These methods have the same effect of wrapping the RGB value into an instance of java.awt.Color but use less memory and are a little faster as they do not create objects with overhead.
