OSG does not do 2D drawing to images. You can do your own by getting the
data pointer from an osg::Image and drawing pixels into that (if you
feel the need to write your own line, circle, flood-filling etc.
algorithms :-) ), or you can use an imaging library (ImageMagick, etc.)
to make the image and then get the data from that library and copy it
into an osg::Image (or perhaps even use the same pointer if it's a raw
format). No need to save the image to disk and re-read it with OSG.
Hope this helps,
