[geotk] Looking for Java APIs to create a PNG from a double[][]

[Robert Nix]

I see. Good to know. Yea, it's no problem converting them to integers, so i can go that route. Or, if there's some format typical of GIS systems for storing double matrices, that's probably a worthwhile approach too.
Thanks
