Hi Yefei, I don't have available time to investigate right now, but I can suggest you look at src/osg/Texture2D.cpp and src/osg/Texture.cpp for the code that uploads the imagery to the OpenGL texture objects. In the case of the format change this would need to be detected and a new OpenGL object created rather than the old one reused, this would probably be quite a straight forward change as there is already code in place to force a new texture object in case like dimension changes.
