Hi, I have tried to use the CoverageCrop processor at an png image with a color table. I haven't specified a destnodata parameter, and from looking at the code I see that it will be set to 0,0,0. I want to mask the image with a multipolygon geometry. In the resulting image, and the original, there is no color black. And the areas outside the given ROI has instead a blue color. A color that is part of the original color table. Is it a bug in this processor that doesn't extend the color table of the resulting image with the black color?
To get a transparent background I suppose I should make sure that the Source coverage is of the type ARGB, and that I specify a color for destnodata parameter. Is this the right approach. Could this be part of the documentation for the processor? Cheers, Roar Brænden
