I was looking for a simple way to load DDS files in python.
I found this: http://pyffi.sourceforge.net/ (but I am using pythin 2.7 so I can’t use it, it requires python3) Has anyone used that, or have another way of easily dealing with DDS file loading/viewing?
I also noticed, that pyglet appears might have some ability to load DDS (I didn’t try this): https://github.com/agileperception/pyglet/blob/master/tools/ddsview.py
I found this reference here: https://gist.github.com/bjorn/4635382
For anyone else looking … I converted that to python (made it a simple class) that returns a QImage - Most tools, I am often displaying stuff in Pyside/PyQT anyway.
