color

This script "dithers" RGB images to 16-bit color, either:

ARGB4444/4096colors+16levels of transparency,
RGB565/65536colors+ no transparency, or
ARGB1555/32768colors + fully transparent or not.

The higher-depth dither is especially useful for mobile developers who need to pre-dither
assets for 12-bit screens.

Version 0.2 - Added RGB565 and ARGB1555.

Please email me for any issues... I'm pretty swamped, but I'll try to address!

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:

[updated 11/28/2011 be 2.7 compatible- A HUGE thank you to François Collard for providing the update.]
Another simple, but I hope useful, color toning automation script designed to assist in adjusting flesh tones in portraits. It doesn't do anything that you couldn't do on your own a few other ways, but if you like fiddling with the complexion of subjects in portraits, and like me, you are a tad lazy, you might find it helpful.

This plugin removes low frequency brightness and color differences from image. It's dedicated for creating textures for computer graphic from photos. But it shuld be usefull for other puroses too.

A simple script to make the edges of a selection or layer glow with the selected colour. The script will act on the active selection first, and if it cannot find that, the alpha channel of the current layer. All changes are made to a separate layer so you can duplicate, mask and move them around to your heart's content.

The script enables you to do two image adjustment operations to all images in a folder:

1. Individually adjust the color balance in shadows, midtones and highlights
2. Adjusting the Brightness and Contrast

You choose a folder with a folder browsing widget, you can also specify the file extension of the files you would want to change(useful if you have non supported files in the same folder).
