The anser would be...
AffineTransform t = new AffineTransform();
...
t.setToScale(dx,dy); // here you set your magnification level ...
if (mode ==1) to = new AffineTransformOp
(t,AffineTransformOp.TYPE_BILINEAR);
else to = new AffineTransformOp
(t,AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
res = to.filter(bi,null);
Hope that helps ...
