Ciao Thomas,
I was looking at the ColorMapNode class and It might be that I have
added a bug while trying to make it more leanient towards bad band
numbers.
I am trying to reproduce your problem, anyway, would it be possible to
have some sample data to try this out. You mention that you write this
geotiff out, can you send me one of this geotiff or part of it?
SImone.
