Once you have a handle of the image (ie you read it into memory) you can use java.awt.Image to do this. http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Image.html

SYS Exception caught java.awt.color.CMMException: General CMM error517

without seeing what you did, no clue why you get an exception. you should be able to pass null as the observer.

I tried null also.. even it gives Exception..only for some images..
and i saw in sun website that it is a bug in jdk..
