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).

Smart Separate Sharpen

Implements a new version of smart sharpening (redux) combined with separate sharpen to give better results. Thanks to Michael Kolodny for working on this.

Updated to work with Guimp 2.8.

Simple Contrast Mask

script-fu-simple-contrast-mask adds a contrast mask layer above the current active layer. A contrast mask brightens the dark parts of an image and darkens the bright parts. This serves to enhance details.

The script is called "simple" because it does not ask any questions. It assumes defaults for all parameters. Specifically, the radius for the Gaussian blur is set to one percent of the shortest dimension of the image (width or height). The user can adjust the blending level after creation by adjusting the opacity in the layers dialog.

script-fu 'parametric curves'

This script is used to draw user defined or library parametric curves.
A simple java like math language is used to define curves or families of curves in GIMP layers. These can be exported to animated GIF's, SVG path, or included in GIMP images.

Stars in the sky

This script-fu makes a sky with millions sparkling stars in a new layer. The layer's dimensions, the star's spikes' length and the flare intensity can be changed. The script is based on this tutorial.
This script is useful for create Space Art images, because the stars are convincing.
Good creating !

Wood Grain

A simple script to generate a wood grain pattern. You can control for the dimensions of the resultant pattern. Results are generated in a new layer in the active image.
