This is a script for The GIMP, a image manipulation program. Basically it consists in drawing circles with sequencial numbers inside, so some can "label" parts of a image to reference in another document.
To install it, just move the script to your local scripts directory, in Unix systems it is located at ~/.gimp-2.x/scripts. I don't know about Windows.
This is an attempt to automate making a galaxy via GIMP. I'd seen a few excellent tutorials, but none that could be easily automated. One of the resulting pictures is attached to this page.
The galaxy can have any number of arms, and they can have varying degrees of curvature. Very high degrees of curvature will result in an elliptical galaxy rather than a spiral. Stars can be added, and the galaxy can be set to have any perspective or color.
A Gimp script which turns a photograph into a black and white image which can look quite like a charcoal drawing. Works with RGB, Indexed and Greyscale images.
Results can be variable and are dictated by the tonal values of the photo used. Although small adjustments can cause quite large differences, the default settings should provide a reasonable starting point but do be prepared to experiment.
Since the previous script is for an isometric wall, the obvious choice for the next script would be one to automatically generate a wall. I'd written one previously, but this seems as good a time as any to post it!
This script-fu turns a "flat" image into isometric image. This helps to draw floors. It can also scale image with few options (ratio, a second layer with interpolation and opacity)...
You can find "02 - Isometric Floor" in Filters>2D Isometric-Fu>
Why is there "a second layer with interpolation and opacity" for scaling?
There is always a first layer without interpolation to try to keep the grain texture. This is practical for stone for example. The opacity of this layer is always 100%.
