Description:
LSE - is a powerful script for creation effect of the lightsaber. This script use only GIMP procedures and don't require any external scripts or plug-ins. Script doesn't has any license, so you may use it's code for any purpose.

Main features:

Creates a new spritesheet (animation frames) from the layers of an image.


1) To install, copy SpriteSheet.scm to {GIMP-HOME}\share\gimp\2.0\scripts\SpriteSheet.scm
2) Either close Gimp and re-open, or simply select menu: Filters > Script-Fu > Refresh Scripts
3) Load your images via File > Open as layers (select all the images you want to in the spritesheet)
4) Optionally re-order your layers to determine ultimate order. Bottom-most layer will be left-most image in final merge.


Takes a wide panoramic image and bends it into a rainbow-shaped image in a way that preserves scale and aspect ratio.

Partitions an image into tiles (with, optionally, either gaps or overlaps between them) and then writes each tile as a separate jpeg file.

An alternative method of doing the same thing would involve first setting up a grid of guides (eg, http://registry.gimp.org/node/12003), then using Image->Transform->Guillotine (as noted here: http://registry.gimp.org/node/20826), and then saving each of the generated images to a file.

This script takes a picture, create a white background, and off-center the foreground on it. Then it add a dropped shadow.

Example:

Updated 2011/11/28: I've modified the script to have it work without any error messages with at least Gimp 2.7.4

Creates a picture which is a duplication of the current picture upscaled and blured as background,
and the current picture itself with a border and shadow around it as foreground

Example:

The second version of the script add a dialog box that let you modify the blur ratio as well as the shadow ratio.
I also added 2 toggle button to control the de-saturation of the fore/background.

Takes an image, makes four 1/4 scale copies, and reflects them about vertical and horizontal axes to achieve a four-fold symmetry.

Note: As well as being atrociously inefficient (eg, by scaling the same image four times, instead of making copies after the first scaling), this code does substantially less than the "Small Tiles" dialog (which comes standard in Gimp in /Filters/Map)

Provides a kind of poor-man's HDR (high dynamic range). It doesn't actually increase the dynamic range; in fact, it decreases it, overall, but in a way that maintains local contrast. But this gives you some headroom to increase the contrast of the image overall, thus enhancing the local contrast.

Creates a white (or black) border around an image that merges in with the image so that on a larger white (or black) background, the image appears to have a ragged border. This is similar to the Gimp's Fuzzy Border, but it adapts its jaggedness to the image. (Also unlike Fuzzy Border, it is deterministic, it does not depend on random number seeds.)

Some examples of what I mean by a jagged border that "adapts" to the image, which also illustrate the difference between a white and black border (it's not just the color), are shown in this triplet of images:
