Fast but anti-aliased resizing in Java

Question

Hi!

I need an algorithm for resizing images in J2ME. The faster and lighter, the better. But nearest-neighbour is not an option as I need anti-aliasing. Something like Hermite interpolation sounds OK. I am not an expert there, so no need to laugh.

Note: I won't need colour unpacking as the data will be grayscale.

Thanks a lot!
