I think you should change your tack, instead of trying to modify the output of a component, instead, modify the input...

So all this does, is apply a circular (alpha based) mask to another image

BufferedImage master = ImageIO.read(new File("/Volumes/Disk02/Dropbox/MegaTokyo/thumnails/megatokyo_omnibus_1_3_cover_by_fredrin-d4oupef.jpg"));

int diameter = Math.min(master.getWidth(), master.getHeight());

BufferedImage mask = new BufferedImage(master.getWidth(), master.getHeight(), BufferedImage.TYPE_INT_ARGB);
