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).
Scales an image multiple times in defined step sizes until the desired size is reached while retaining the aspect ratio of the image.
This is basically the "Scale in steps" script from K.-M. Hansche tailored to my needs.
Give the desired size of the image and select whether this is for width or height. The step size defines how much pixels the image will be shrunken every time. When flattening the image, the layers will be merged and the image is automatically cropped. The other options control the scaling itself.

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.
