Hi Sean,
There is a osg::Image::readImageFromCurrentTexture(..) method that you
could use, you'll need to do the call within a graphics thread, such
as by using an draw callback, and as the method reads from the current
OpenGL texture you'll need to do a texture->apply(..) prior to calling
image->readImageFromCurrentTexture(..).
Robert.
