Quick update. The samplemodel of the image is modified by the styling operation. Ad since b&white map was in MultiPixelPackedSampleModel, it resulted nicely handled (those images are heavily compressed). After the styling the image has a PixelInterleavedSampleModel model, which very probably makes it explode.
Hmmm, so for these types of maps, it is better not to play with style. Is there a way to make just a color transparent?
