Description
This GIMP script generates random splatter brushes by automating the process described in my Splatter Brush Tutorial [link]

I'm currently in the process of creating a small series of GIMP scripting tutorials, in which I will be showing how to create this script.

Part 1: [link]
Part 2: [link]
Part 3: [link]
Part 4: [link]

INSTALLATION: Just download the zip file, extract the Splatter.scm file, and move it to your GIMP scripts folder, which should be something like (in Windows) C:\Users\username\.gimp-2.8\scripts. Then restart GIMP or refresh your scripts (Filters>Script-Fu>Refresh Scripts).

After that, the script should be accessible through File>Create>Splatter Brush. The user has the ability to set 3 parameters: (1) the "Brush Size" determines the dimensions of the square canvas, (2) the "Splatter Amount" determines how many strokes of the Sparks brush are used to generate the splatters, and (3) the "Splatter Thickness" controls the low threshold value of the Threshold tool, which determines (to some extent) the thickness of the splatters.

RECOMMENDATION: Try increasing the Sparks brush's "Spacing" in the Brushes dialog prior to running the script. This will help the splatters appear more random, but you may need to increase the Splatter Amount to compensate. I would add a "Spacing" parameter to the script if I could, but it currently seems to be impossible to change the spacing of one of GIMP's default brushes via script-fu.

BONUS: The Splatter.scm file includes a second script called "Smooth Threshold" which is used by the Splatter Brush script. It applies the Threshold tool followed by the "blur+levels" trick to smooth out the pixelated edges. You can try using it on other images by going to Colors>Smooth Threshold.
