This script makes a ring system that you can add to a picture of a planet, and was adapted from a Photoshop script. This script is updated for GIMP v2.6
The ring system can be any size from 300x300 to 3000x3000, and can be tilted to any angle. The whirl-and-pinch portion of the script is time consuming, but using at least 8 iterations make the rings look very nice. The thickness of the rings can be controlled using the inner and outer ring ratio values in the script. The closer these two values are together, the narrower the ring.
This is an Exif Viewer, mainly for jpeg photos taken with a digital camera. It is an update of the "Exif Browser" plugin from the old registry. It requires a recent version of libexif (tested with 0.6.16).
Instructions for Linux:
You need to have gimp already installed on your system. After downloading the file exif-browser.tar.gz, do the following steps.
Save all layers as TGA files, discarding alpha channels and applying layer masks as alpha if they exist. Name becomes imagename-layername.tga
This script is created by Joao S. O. Bueno at my request and I take no credit for it's development.
Appears in /Layer/Transparency/Copy Mask to Other layers of the Image window.
I wrote this script using GIMP bug #88361 as inspiration.
This script provides three functions that expand GIMP's ability to deal with indexed colors. I designed them with pixel artists in mind, who frequently store their target palette as a set of swatches in one region of the image they're working on.
(Image) > Colors > Map > Colormap to palette
Creates a GIMP palette based on an indexed image's colormap, which can then be used just like any normal GIMP palette.
Performs a value-inversion on the current layer, based on its representation in the YCC colorspace. The result is similar to the existing "Value Invert" command (but without that command's color-distortion introduced from low RGB values) and can be quite striking on certain source images.
