Hi Blake, There isn't a convenience method built into osg::Image to do this, but you could easily use gluScaleImage to convert the data. The new inbuilt glu lib within the OSG-3.x has the ability to work without a graphics context, this is enabled by passing in a PixelStorageModes structure in the gluScaleImage call. See the implementation of osg::Image::scaleImage(..) for an example of how this is done.
