Does anyone have an example of adding a mask while creating a NITF file? I can create NITF files OK but can't figure out from the "RFC 15: Band Masks" documentation how to include a rectangular mask area. When I call CreateMaskBand on the dataset, where does it go? Calling GetMaskBand from any of the existing bands, after CreateMaskBand, always returns an error. I was intending to use RasterIO to write a black rectangle into the middle of the mask band (assuming I can find it) in order to hide the centre of the NITF output image.
I don't even seem to be able to find an example NITF file with a mask in it - can anyone point me to a good example? Thanks in advance Gary
