Generating a terrain bigmap with npcs on it
 

Is there anyway to generate a bigmap for terrain maps that include npcs? I know I can manually warp myself to each level and use makescreenshot(); then shrink them with drawstrechedimage(); and put them on a drawingpanel and piece them together then save that image. The problem with that is the drawing panel causes Graal to freeze and sometimes my client crashes before it can finish. I'm just looking for an alternative since I know I can do it that way.

Just take the screenshots and piece them together using some external tool? That's what I always used to do for this situation before NW2PNG (which obviously doesn't support terrain). I did that for quite a few maps, both terrain maps for GK and regular old flat GMAPs.
