Lightsaber

Creates a Lightsaber effect.
To successfully create the effect, you need a black layer with a white line (roughly 2-10 pixels wide)
The layer must be selected.

Make Your Own Planet - Script of MarvinX's Tutorial - Updated for Gimp 2.6

This script automates many of the steps in MarvinX's fantastic "Make a Planet" tutorial, with a couple of added features. There is an atmospheric haze around the planet, and there are stars on the background layer. This script does not do the IWarp step. I leave that to the individual user to make wherever they want.. Everything else is in here.

Lomo-Gimp

Lomo-Gimp tries to give your digital pictures the warmth of those taken by an old rangefinder analog camera. Think of it as a Kodak Instamatic or a Lomo Holga faking effect. It enhances contrast and saturation, and applies a light and a dark overlay, trying to emulate incorrectness in exposition. Please note this does nothing to emulate the chromatic aberration peculiar in pictures taken using a real Lomo.

Get it at Lomo-Gimp.

Film Grain Script

This is a script which simulates the typical film grain of high ISO pictures. I scripted exactly this description:

Copy it into the scripts folder from GIMP, you will find it then under Filters -> Generic -> Film Grain.

Filtered BW

This script converts color images to B&W using channel mixer settings,
which simulate the use of color filters in B&W photography. It allows to choose many predefined filters and set their intensity. Previously posted to old registry in July 2006, now updated to work with GIMP 2.4. Avoid setting intensity to 1, besause it totally filters one of RGB channels and increases noise.

Lomo Script with Old Style Colors

This script simulates the Lomo effect.
Copy it into the scripts folder from GIMP, you will find it then under Filters -> Light and Shadow -> Lomo.

msx1 filter

The code still have some accuracy bugs when compaired with its sdlBasic version, since i were getting some problems when recoding it to Python-Gimp.
The script converts a rgb picture into msx1 (also colecovision and sega sg1000) display limitations, which have a predefined palette, and a maximum of 2 colours in each 8x1 pixels cell, trying to provide this cell as the most close as possible from their rgb original.
As well, the code is a bit slow (a 320x240 picture can take around 1 minute on a 2ghz dualcore computer) since it processes pixel by pixel.

zx spectrum filter

The code still have some accuracy bugs when compaired with its sdlBasic version, since i were getting some problems when recoding it to Python-Gimp.

The script converts a rgb picture into zx-spectrum display limitations, which have a predefined palette, and a maximum of 2 colours in each 8x8 pixels cell, trying to provide this cell as the most close as possible from their rgb original.
As well, the code is a bit slow (a 400x300 picture can take 1 minute) since it processes pixel by pixel.

crosseye2anaglyph

A converter from 3d crosseye photos to 3d anaglyph red-cyan.
The code is slow because it works pixel by pixel, please try first with small pictures, like 640x240 (from 2x 320x240) - i think a similar code can perform faster, like moving a group of pixels (a half of the picture in this case) at once from just one colour channel, but i have no idea about how to do it, specially how to crop out the result, and defining a GUI for choosing if we want a rc or a cr anaglyph. All help are very welcome! :-)

Halftone Cluster

An picture filter coded as Gimp-Python plugin. What this filter does is to reduce the colourspace of a 24bit rgb picture into a 3bit, using a predefined halftone cluster for it.
