Have you looked at the RasterBandNodataSetter? It will allow you to define the "black parts" as NODATA, rendering them transparent in most clients.

thanks ,it looks what i need and i did nodata value 0 and output in inspector looks great but when i write the output to pdf by pdf writer .it gives me error and unable to write it .

but without using nodata value ,pdf was able to write the image but with black parts .

another hint :i found also some parts of text deleted also after using nodata value . is there another way to remove blackparts only .

could u help me ,thanks again
