Exif Viewer

This is an Exif Viewer, mainly for jpeg photos taken with a digital camera. It is an update of the "Exif Browser" plugin from the old registry. It requires a recent version of libexif (tested with 0.6.16).

Instructions for Linux:

You need to have gimp already installed on your system. After downloading the file exif-browser.tar.gz, do the following steps.

TGA Batch Save

Save all layers as TGA files, discarding alpha channels and applying layer masks as alpha if they exist. Name becomes imagename-layername.tga
This script is created by Joao S. O. Bueno at my request and I take no credit for it's development.
Appears in /Layer/Transparency/Copy Mask to Other layers of the Image window.

GIMP Indexed palette selection tools

I wrote this script using GIMP bug #88361 as inspiration.
This script provides three functions that expand GIMP's ability to deal with indexed colors. I designed them with pixel artists in mind, who frequently store their target palette as a set of swatches in one region of the image they're working on.

(Image) > Colors > Map > Colormap to palette
Creates a GIMP palette based on an indexed image's colormap, which can then be used just like any normal GIMP palette.

GIMP YCC Inversion

Performs a value-inversion on the current layer, based on its representation in the YCC colorspace. The result is similar to the existing "Value Invert" command (but without that command's color-distortion introduced from low RGB values) and can be quite striking on certain source images.
Accessible via (Image) > Colors > Components > Luma invert.

arclayer

arclayer takes a layer (for instance, a text layer) and bends it in a circular arc of a specified radius. Home page at http://shallowsky.com/software/arclayer/

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.

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.
