Offset

This script-fu allows to shift tiles/bricks/blocks one row or column out of two. It will help to draw brick walls, etc...

You can find "00 - Offset by froGgy" in Filters>2D Isometric-Fu>

I know this is not isometry, but I want to gather together in the same directory all the little script-fu that can help draw walls, floors, roofs etc...before their transformation into isometry.

example:

Galaxy

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.

Black-and-White Film

A simple script that desaturates the image the way different black and white films would. The script is based on information from http://www.prime-junta.net/pont/How_to/100_Curves_and_Films/_Curves_and_....

Updated: ver 1.1 - replaced "Flatten Image" option with the more logical "Work on Copy".

Brick Wall

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!

Isometric Wall

This script-fu skews an image in order to help to draw walls for isometric projection. It can also scale image with few options (ratio, a second layer with interpolation and opacity)...

For further explanation, see also http://registry.gimp.org/node/25040

You can find "02 - Isometric Wall" in Filters>2D Isometric-Fu>

example:

Isometric Floor

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>

example:

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%.

Isometric Tile and Template

This script-fu creates an isometric tile in your patterns and a template from it.

You can find ""00 - Isometric Tile and Template"" in File>Create>Patterns or in Filters>2D Isometric-Fu>

example:

Curveloader

This is a plugin to load GIMP curves via script-fu (or other scripting language). The plugin returns arrays with the curve values for use with
gimp-curves-spline or gimp-curves-explicit

Maths and Islamic Art & Design

Islamic art history is rich with geometric patterns and color.
The art certainly have many applications, whether in religious projects and what the formal plan can be used.

Clear paper to "white" for a scanned pictures

This simple script helps to clear "gray" paper-background for a scanned documents (pictures) to a white color. It is used by myself to clear lot of files. In batch mode, processed files must have extension JPG and changed versions will be saved to the same place, replacing original. Tested on Win32 GIMP v2.6, but i think will work with other 2.x too.

p.s. the main idea of the script is described on the this page (russian only, sorry).
