   Maybe you should have a look at JAI, I came across the following example for scaling images with it:

   ParameterBlock pb = new ParameterBlock();
   pb.addSource(im);
   pb.add((float)selrect.x);
   pb.add((float)selrect.y);
   pb.add((float)selrect.width);
   pb.add((float)selrect.height);
   RenderedOp opCrop = JAI.create(“crop”, pb, null);
   PlanarImage imgScale = JAI.create(“scale”,
   opCrop,
   scale,
   scale,
   (float)-selrect.x * scale,
   (float)-selrect.y * scale,

   Interpolation.getInstance(Interpolation.INTERP_BILINEAR));

   Might just work!

   You’re right, but it adds the extra requirement of having JAI installed, which I’m quite hesitant to do right now. I might look in to it though.
