Since the previous script is for an isometric wall, the obvious choice for the next script would be one to automatically generate a wall. I'd written one previously, but this seems as good a time as any to post it!
This simple script helps to clear "gray" paper-background for a scanned documents (pictures) to a white color. It is used by myself to clear lot of files. In batch mode, processed files must have extension JPG and changed versions will be saved to the same place, replacing original. Tested on Win32 GIMP v2.6, but i think will work with other 2.x too.
p.s. the main idea of the script is described on the this page (russian only, sorry).
CarTOONize your pictures using a script-fu script. Script has controls for adjusting the line thickness, as well as the 'black' shadows. Now you can adjust the number of color levels from 1 to 5 (the default is 4), 1 being very flat, 5 adding more color levels. Can enable/disable the black shadows, as well as a pre-filter * (It uses the GREYCstoration, G'MIC, Selective Gaussian, or Despeckle filter as a 'surface blur' to eliminate noise, which is user selectable). You can now either overwrite existing or generate a new layer.
MAP to Object is already included in gimp but with a too poor and microscopic a preview
with a simple hack i multiplied the hardcoded preview size from 100x100 to 600x400 to offer a much bigger preview.
..here you may see the difference!
would be possible with some knowledge of C a much better preview:
