Detailed Description

This class extends osg::Image with an interface to support vtdata's Bitmap operations and use vtdata's vtDIB. It is useful for creating images in memory.

If you are going to use OSG to load an image from disk, you must use osg::Image instead, which can be loaded with osgDB::readImageFile.

A common use for an image is as a texture map for a textured material, by passing it to vtMaterial::SetTexture().
