Can You Export The Ingame Maps To .png ?

I'm looking for a good clean map of cirdas caverns .
Looking at bg wiki they are full of horrible .jpeg artifacts.
remapster looks prettty nice of cirdas caversn but lacks some rooms and the markers are in the way for what I need it for.

Is there a easy way to export it from the game in a decent resolution ?

Crop these two. The ingame resolution is 256x256 so no, there's no way to export them at a "decent" resolution because the original resolution is crap. The above is the .bmp images extracted with AltanaView - it's a lossless format so just crop and re-save in bmp and you're good. I was too lazy to do it myself.

Thank you so much.
I cab for sure crop myself. I just needed a source with no jpeg artifacts.
