i'm not sure what you're asking, actually.

are you wanting to draw annotations on the image without altering the 
pixbuf's data?

you can either use Gdk drawing primitives to draw directly on the 
screen after drawing the image (which can be a pain to keep up), or use 
Gnome2::Canvas for structured graphics.

otherwise, you can just alter the image data, keeping a pristine copy 
separate from the annotated one.
