script

This is a script to generate animated lightning bolts, like the one below, with various options.

Here is a quick summary of the options for this script:

Image X and Y size: Controls the dimensions of the final image. Recommended dimensions are a really tall image.
Number of frames: Number of frames (layers) in the final image.

Instability: large values make for quick fluctuations and jagged lightning, small values make for gentler curves

A simple script to generate a wood grain pattern. You can control for the dimensions of the resultant pattern. Results are generated in a new layer in the active image.

Version two (sf-will-wood-gradient.scm) allows you to control banding frequency, and specify your own colours

A script to generate an animated fire, tileable horizontally. Requires the "Incandescent" gradient that comes with the GIMP

Has the following options:
Image X and Y size: controls the size of the resultant image
Vertical and Horizontal Scale: controls the scale of the flames.
Flame Height: controls the maximum height of the flames as a fraction of the image height.
Detail: controls the detail on the flames, but too much makes them look strange
Gradient: Choose a different gradient to use

FIL (Film Imitation Lab) is a powerful script for old photo simulation. FIL has a modular architecture and can use binary extension (plugins).

Current version: v1.7.2 (June 17th 2012).

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.

Draw guides is a simple script which draws guides using current pencil on the current layer. Useful if you want to see guides when you print the image.

Resize-match-dpi is a GIMP Script-Fu script to resize or scale an image along with scaling the DPI. If we scan a 4.75″ x 4.70″ image at 300 DPI with a pixel resolution of 1425 x 1409 and we want to scale it down to 1280×1266, most programs will rescale the image but not touch the DPI. This means when the image is viewed or printed it will appear too small (4.27″ x 4.22″). This script scales the DPI to match the new pixel resolution so it will still appear as 4.75″ x 4.70″. Comments are greatly appreciated.

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.
