Subject: Resizing GdkPixmap Images

I want to be able to resize, and if possible, rotate images stored in a
GdkPixmap. Are there any functions to do this? Also, (this could apply
if no functions exist, and I have to write them myself), how are the
images stored in a GdkPixmap struct?
I'm writing a map editor or sorts, and I need to do this to accomplish
various zoom levels, and not having to have a differnt image stored for
every zoom level.
Concerning this: what would be the best way to store and display a map?
Let's say the entire map would take up a 10,000 x 10,000 pixel area.
Would it be best to parse it all beforehand, and just put the huge
canvas into a scrolled window? Or would it be better to have a smaller
canvas, and draw onto it just the section of the map that is being
displayed?
Thanks.
