Image Color Tints

How would I go about adjusting the RBG values of an Image to give it different color tints?!?

I read an article of Sun's Java website, they used ToneAdjustmentOp to accomplish this ... funny thing is that it doesn't exists in their API documentation!! So *** do I import?

Here's the link: Java Tutorial

Yeah i cant seem to find any Java 2D API documentation either. Here is the closest thing i could find. http://java.sun.com/products/java-me...java2dfaq.html
