OK, so I'm guessing there's no way to decompress other compression
types, such as ARB compression, using OSG calls?

Thanks,
Greg

Hi Greg,

Unfortunately there isn't a means for converting DX* compressed
osg::Image out into uncompressed osg::Image's, to do this I'm afraid
you'll have to read up on the DX* formats and work out how to
recompress them.  Once you have the uncompress osg::Image's you'll be
able to use the OSG writeImageFile so this part of the equation will
be straight forward.
