What sort of image are you zooming on?  For arbitrary data, I suppose some
interpolation scheme would be the best you can do, but if it's possible to
rebuild your image, that might be preferable.  In my case, I work with
seismic data (surprise!), so I dsimply rebuild the image as I zoom on it.
It is reasonably fast, considering that any kind of interpolation is also
going to be computation intensive.
