Yes. I am a co-maintainer so that I can release PDL::IO::GD with PDL. Judd Taylor is the author or primary maintainer. PDL and PDL::IO::GD are two different namespaces. > 2. (Minor point).

Documentation bugs are bugs. You'll need to provide more specific information for an official bug/problem report. See BUGS for what to include. > 3. (Major point).

There was a previous discussion on pdl-porters about making a LUT for image display. See the thread at http://mailman.jach.hawaii.edu/pipermail/pdl-porters/2006-December/000643.html Good luck, Chris
