Package: pslib1
Version: 0.2.6-2
Severity: normal
Tags: patch
pslib's png importing routines aren't aware of how to correctly handle the
presence of the alpha channel i.e. on RGBA png's. My choise was (since the
lack of support for it anyway) to instruct libpng to strip off the alpha
channel, which leads to a working import.
