I don't understand exactly your problem but I will try to explain what I have done:
MapperGui is used only for generating image map of a zone, there are my source in
http://minecraft.amtenael.com/daoc/MapperGUI.tbz, I remember only theses changes:
- Recompiled _dxt1.so for linux x64
- Small fix for daoc path
- fix of some polygon (when internal part of the polygon is filled instead of external part)
- add allMaps.py for generating zone 1 to 250
I think it doesn't work on windows (too old libraries are used) so use it on a linux x64 with python 2.7 in command line (there are many bugs with the GUI). I use it with command like: "./mapper.py -out zone1.png -settings mappergui.ini -zone 1 -scale 2048".
Many zones are blurred when you set scale at 4096 or more so it's not very useful...
