shape

Generates a complex rim around an arbitrary shape from a line of pixels. Get it from SourceForge: http://gimp-wrapmap.sourceforge.net/

This script creates nice shapes in Gimp. The model is a layer/path it will be duplicated a few times and these copys will be moved and/or rotated.
The coolest effects can made with a spline (from a path). In the new version you can choose if you take a path or a layer. The interest here is, that you don't lose on quality.

So, here's a little guide:
1. Create a path and make it visible.
2. Start the scirpt (Filters/Shapes) and make your settings.
3. Go to paths dialog, right click -> Merge Visible Paths
4. Stroke the Path with default options

Sets the selection to a sunray-like pattern, taking parameters such as inner and outer size, whether or not to have flowery edges, thickness, amount of rays, and a randomize switch.

Every paper size has a different shape, and none probably match the shape of the images produced by your digital camera. 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
