This little bit of Script-Fu converts all images of a specified extension in a single folder to greyscale .gbr files. script-fu popup prompts you for the folder containing the images, and which extension to filter on.

Brushes are created in the same folder as the images, using the original filenames (but with .gbr as the extension instead of frex. .jpg).

Tested in Windows XP with GIMP 2.6 - not tested in other environments or versions, but as this script is very bare bones, it should work on any GIMP version from at least 2.2 up (not sure about earlier).

This script scales the image in multiple steps, automatically stretching contrast HSV at every step in order to make the resulting image have a better quality and contrast, preserving hue.

The user is required to specify the final image long side length (in pixels) and the scaling ratio in percentage of each step, default percentage is 66.

According to the plugin "plug-in-autostretch-hsv" by Scott Goehring and Federico Mena Quintero, stretching contrast HSV may give bad results. Contrast stretching can be disabled.

This script-fu script is a deeply modified version of the comic-book1 script by barky. While that script works well for web resolution images, higher res images need a larger cell size to keep the correct look and feel.
The plugin-interactions have been left in a active state to allow the user to fine tune the effect based on resolution.
This script uses the following default plugins:
hue-saturation
posterize
unsharp mask
newsprint.

17, June 2010 -- Script repaired to remove fixed image id.

This is a simple python script, which creates spirograph type curves. There are endless varieties which can be generated. There is a page on my site with some documentation:

A simple script to make the edges of a selection or layer glow with the selected colour. The script will act on the active selection first, and if it cannot find that, the alpha channel of the current layer. All changes are made to a separate layer so you can duplicate, mask and move them around to your heart's content.

The Stit-ch-art is a script-fu extension for the GIMP. Stit-ch-art creates a cross-stitching chart based on a given image. It applies the modified Madeira palette with 256 colors on the copy of the image, and then scans it pixel by pixel for color codes while generating black and white chart ready for printing (includes color legend from Madeira).

The attached zip-file contains the script stitchart.scm, readme.txt, and 2 palettes: madeira.gpl and madeira256.gpl.

This script takes two animations, using layers as frames, and merges them together with the blend mode and offsets specified. You can choose to make the animation length be the LCM of the two animation lengths, or the minimum length.
