Script-Fu

This script-fu makes a sky with millions sparkling stars in a new layer. The layer's dimensions, the star's spikes' length and the flare intensity can be changed. The script is based on this tutorial.
This script is useful for create Space Art images, because the stars are convincing.
Good creating !

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

Slices and joins scriptfu is useful when you want to split one image 'file' into smaller 'files', and to recombine it successively. One single image 'file' can be split into unlimited number of files. Image-slice script save on the file imagename.rcm all the data for the reconstruction.

Bugs fixed and enhancement:
Duplicate file name
Invalid path name (Linux user)

Slice export maintains the transparency.
Add Option in order to recompose all pieces on a layer.
Limited the maximum number of lines and columns to the dimension in pixel of the image.

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

This GIMP script adds an old paper effect to the image. It is based off of the tutorial by RobA at http://forum.cartographersguild.com/showthread.php?533-Tutorial-Creating...

Seperate layers are added so the image can be fine tuned after the script is run.

This script puts guides at 50% Vertical and 50% Horizontal, to create a crosshair at the exact center of image/layer.

This script creates guides at 1 inch intervals. It is dependent on pixels per inch settings.

This script sets guides at every 10% Vertical and Horizontal.

This script sets guides at a 10% border around the image.
