Imprints a non-intrusive faint text watermark sparsely repeated over the entire image. The watermark is meant to be visible upon close inspection without disturbing the viewing of the image.

The watermark visibility can be fine-tuned by changing the opacity of the watermark layer.

Contains an image plugin that operates on an open image and a batch
plugin that requires the filenames for the source and modified images.

Requires Python.

Install in the plug-ins GIMP directory. Make sure the file is executable or GIMP will ignore it.

This script it allows you to create polar series into image from the active selection.

Note: I accidentally posted this as a plug-in first. I've now correctly posted it as a script.

This script allows the user to select an item in the image and to create a true polar array of the selected object (think kaleidoscope as opposed to Ferris wheel seats). It is useful for creating objects that possess radial symmetry.

The user can control:
-center point of rotation
-distance from the center point to the objects in the array
-starting angle for the rotation
-angle between each copied object
-number of objects in the final array.

dechroma is a simple but effective chroma noise reduction tool. Chroma noise appears usually in high ISO photographs. The method used in this script allows to reduce noise but does not affect details. It decomposes the picture in the LAB channels, blurs the chroma noise on the red and blue channels, and recomposes the picture. The default settings of the blur radius should be appropriate for general uses, but can be change. It's probably safer to apply primarily dechroma on selections to avoid some red or blue smears on transitions.
