[JAVA2D] Compositing

I'm having trouble compositing transparent CMYK images with JAI, so I'm wondering how frightfully ill-advised it would be - performance-wise - to simply loop through the pixels on a BufferedImage and composite them manually. -Adam

I tried but nothing special happened, at least with my small test code. Cheers, Mik. [Message sent by forum member 'mikofclassx' (mikofclassx)] http://forums.java.net/jive/thread.jspa?messageID=206807 === To unsubscribe,

Re: [JAVA2D] java2d Compositing - OpenGL fragment shaders

Michele, you may wish to try turning on OpenGL extension limits in your nVidia Control Panel. I've found that my particular JRE (6.0) acts a little funky when given free reins with extension limits, and it works like a charm when the setting is changed from the default. I'm not sure it will

[JAVA2D] java2d Compositing - OpenGL fragment shaders

Hello all at java2d, Hello Chris, after bouncing my head for some time over OpenGL, alpha compositing, accumulated and premultiplied alpha I decided (curiosity) to take a look at the j2se6 source code just to see what happens behind the scenes. All I discovered (surprise ?) is that the OpenGL
