textures. Near the top of the function that implements texture subloading, osg::Texture::applyTexImage2D_subload(), the local variable compressed_image examines the _image's_ pixel format to see if it is compressed. However, further on, in calls to getCompressedSize() the _texture's_ pixel format is used. In my application's Texture2D class, I use osg::Texture::USE_ARB_COMPRESSION to osg::Texture2D::setInternalFormatMode(), which causes the internal format to become one of the generic ARB_COMPRESSED types, which do not have a specific size. Thus the recent warning message added to osg::Texture::getCompressedSize() is triggered. The correct behavior is to use the format mode from the Image class instead of the Texture class within the subload implementation, and then the size is calculated correctly."
