What you ideally want here is to use ome.util.ImageUtil to make a  
buffered image from the rendering engine's packed integer format, this  
is the fastest way to get a buffered image we've found in Java and  
requires *no* data copies:

PlaneDef planeDef = new PlaneDef(PlaneDef.XY, 0);
int[] buf = renderingEngine.renderAsPackedInt(planeDef);
BufferedImage i = ome.util.ImageUtil.createBufferedImage(buf, 512, 512);

The code for ImageUtil can be seen here:

http://svn.openmicroscopy.org.uk/svn/omero/trunk/components/model/src/ome/util/ImageUtil.java

I don't see how you can do what you want with the raw data as it has  
not been rendered to the device space yet.

Let me know if this doesn't help Jost.

Ciao.
