This little utility will create a layer showing which parts of an image will fit on the paper when printed. A wide selection of print sizes are included. Using it will help you layout your image so that important pieces aren't cut off by the printer/lab.

This script-fu was developed under Gimp-2.0 and Gimp-2.4

Turn a boring flat image into a stylish 3D-shadowed-glowing one.

Shape from shading algorithms have been around for a while. Dr. Mark J. Carlotto describes a simplified version using basic trigonometry (Sculptor's Photoclinometry page in the Pacific-Sierra Research Image Shape from Shading section). In that section, Dr. Carlotto describes the Berthold Klaus Paul Horn algorithm for  read more »

Tiles the face of a centered polygon image such that it forms a polyhedral net. This way the image can be folded up into the specified 3D solid. In order for the plugin to work as specified, certain prerequisites must be fulfilled as described in the instructables tutorial here http://www.instructables.com/id/Create-attractive-3D-solids-using-The-GI... .

A set of plugins and scripts for astronomical image processing

Not intended for scientific image processing, due to gimp's 8bit depth restriction (for "pretty pictures" only).  read more »

Scripts:

• Set mode for all layers
• Set brightness / contrast for all layers
• Normalize all layers
• Subtract dark frame from each layer
• Divide all layers by a flat field
• Draw border with image information

Plugins:

Creates a shining glow as demonstrated in the tutorial here:
http://www.gimpusers.com/tutorials/rays-of-light-behind-text.html
This script will only operate on the alpha-layer
It assumes that the layer size is the same size as the image size
It will not add color to the rays as in the tutorial
The rays are now created much like an outer glow, rather than being merged with a background as in the tutorial
Tested in v2.4.2 only
