Here's a little utility I made called hff2png. It's completely useless because L3DT already does this (I wrote this as a programming exercise).
hff2png
Anyway I found it usefull because it quickly converted my large map and allowed me to scale the output images (I don't have L3DT on this computer). It works with mosiac maps if you give it the .mmf file.
Suggestions please I'm trying to improve my coding skills. Maybe I'll make a win32 gui for this or something.
aaron you're an awesome coder man, there's no way I could write something like L3DT. It's amazing you wrote that whole program!
