Tom, It has been a while since I looked into this. I did not find a solution in OSG, and the problem was not important enough to warrant spending more time on it. If I had to revisit this problem today, I would look into using Boost.GIL (Generic Image Library) for the conversion. http://www.boost.org/doc/libs/1_39_0/libs/gil/doc/index.html GIL is a header-only library that allows you to generically convert between different pixel and packing formats. With this library, you could convert an osg::Image object containing .dds data into an osg::Image object containing .jpg data. Alternately, you could create a Boost.GIL image using the .dds osg::Image data and use Boost.GIL I/O to output the Boost.GIL image as a .jpg file. Hopefully, someone can chime in with a simple solution.
