Interesting. The aberrations I've seen happen only when zooming in a lot and are present on the coverage that comes out of the resample (the operation that reprojects the coverage). That happens before java2d can kick in even in the standard path, so it seems odd java2d could cure them. I am inclined to think that may be a different problem, the fast path has indeed never been tested with 16bit color indexed image. But I may be of course wrong as well Having some test data, styles, and requests to make it fail would be good Cheers Andrea ----------------------------------------------------- Ing.
