This script is nother in a series of planet makers. This one makes a banded gas giant. There can be anywhere from one to 20 bands in the planet. Each band is an equal height, and has Plasma noise rendered in it. Each layer is then motion blurred. The result is then mapped onto a sphere, and gaussian blurred to make the edges nice and fuzzy.
This script generates a pattern like the one shown in the attached png. The size of the image can be anywhere from 300x300 to 3000x3000. The pattern can be symmetric, or it can be weighted to have longer sides on one side. The color of the lines in selectable. I'm not sure what this can be used for, but it does make a nice pattern that can be tiled. Enjoy!
A simple plug-in to convert RGB images to YUV in GIMP. This means that after having applied the filter, you will get luminance (Y) in the red channel (R), and chrominances in green and blue channel. By using the decompose plugin, or the channel dialog, you will be able to work in YUV space, and be back in RGB space by the reverse plugin.
A simple plug-in to do fourier transform on you image. The major advantage of this plugin is to be able to work with the transformed image inside GIMP. You can so draw or apply filters in fourier space, and get the modified image with an inverse FFT.
This script will make a single eyeball, and has been updated for v2.6. The colors of the iris, and size of the pupil, lighter iris, and darker iris, are all adjustable. Ideally, the inner eye color should be about half the brightness of the outer eye color to provide a nice transition from the pupil, but any two colors can be used. The image itself can be anywhere from 300x300 to 3000x3000 in size. The eye will have a transparent background. Enjoy! The attached picture is what the final product will look like (your colors may vary, obviously!)
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.
