[Tools] Wall's and search map in Gimp/Inkscape

Hey guys!
Walls and search maps - it is 95% work on area, so I spent nice few hours on creating it in few huge areas.
I like quick and fast work as all people, but creating wall's and search maps in DLTCEP or IETME is strenuous...

I make way to work on it in GIMP or Inkscape or any graphic editor - you know, I like zoom, layers, ctr-z, ctr-y, ctr-c, ctr-v

I make video - hmm, something as how to (sorry for polish GIMP ;/) -

Small description:
biblioteki.zip - it is library for program's, must be in this same directory
from_search.zip - we need write: filename with extension (bitmap.bmp), orginal width and height our area
to_search.zip - we need only drop bitmap, all with extension .bmp will be converted to big .bmp

I have program which add poligons to wed from .svg but I must enhance it.

Small aditional. Program which generate all wall's from .wed to .svg How it work? Easy, drop file with extension .wed and run program, you will get .svg
