Python

This plug-in turns selected layer into a Polka Dot image.
Inspired by this tutorial: http://www.scottphotographics.com/turning-a-photograph-into-a-polka-dot-...

More example on http://krypt77.altervista.org/index.htm (Download-->Plugin Gimp)

Suppose the current layer has a tile-based image (e.g. the tileset for a game). This script will transpose all tiles, so that the tile at the position (1,0) will end at (0,1).

Very useful if you have your sprite sheet as a tall strip of frames (one on top of the other), but you need it as a horizontal strip (with frames side-by-side, as required by Game Maker). With this plugin, you can transpose the frames to convert from one format to another.

Split a layer into many layers, one for each tile. This is useful for editing tile-based images for some games and applications.

If somehow I forget to update the script in this page, check also:

Based on sprite tape - 0.3, these two scripts are complementary.

sprite-tape converts multiple "frames" (think animation frames) one per layer to an image of an array of "frames" in a single layer with a specified gutter between frames. sprite_tape-0.4 differs from 0.3 in the way that the gutter between frames is created.

This is a python script that creates a new image of a color wheel on a transparent background. I wrote this script so that I could have an image of a color wheel to use as a color selector inside a C++ program. I wanted a color wheel image that was not copyrighted. This script was inspired by KEMPER BARKHURST. He wrote script-fu-kbColorWheel.scm. I converted his script to python and modified it to remove the lines between each hue.

Example:

I have modified 'Export Layers as PNG' script of Chris Mohler to generate a svg file beside exporting pngs. It can also create Inkscape layers.

For installation and other tips please look at 'Export Layers as PNG' page: http://registry.gimp.org/node/18440

OK - so I saw this plugin today:
Cross Processing (Xpro) http://registry.gimp.org/node/25007
Which is based on this excellent tutorial by jEsuSdA: http://www.jesusda.com/blog/index.php?id=375

After running through the tutorial, I decided to write another version of the plug-in with a few options.

This plug-in requires Python. If you have the 'Filters->Python-Fu->Console' menu item you are all set. If not, install Python support for GIMP.
The plugin can be found under Filters>Artistic>Cross-Process. Don't forget to make the plugin executable.

Options:

Reduces high ISO banding, blue haze and somewhat chroma noise. Intended for images produced by Olympus gear on higher ISO settings, could be useful on images from other companies. It's fast, but alters colors, lightning of the scene in a dodge-burn fashion. New version adds Gaussian blur on Y, Cr & Cb channels, which can be used separately.

When saving script please remove ending '.txt' extension, and make sure script is marked as executable.

Simple plug-in to colorize the image in all hues (0-360) and save each colorized image in the specified directory.

This plug-in requires the GIMP Python module.

This python plug-in strokes or fills the current selection and creates a 3D glossy effect with a dropped shadow. The color, brush, lighting, and shadow are adjustable through the initial dialog. Use the Filters/Light and Shadow/GlossyStroke 3D menu.

Note: Depending on the color, adjusting the opacity of the "volume" layers can give better results.

It is my first GIMP plugin, so any comment, criticism or improvement is appreciated. The 3D effect parameter could certainly be improved.

12/16/10 - Version 1.2.0
- The light direction is now opposite to the shadow.
