Geomorph is a height field generator and editor for the Linux operating system. A height field is a kind of topographic map. It is a 2D projection of a 3D landscape. Geomorph generates square images and shows a 3D preview of the resulting landscape. The resulting 2D image can be processed with a tool like Povray for rendering the landscape.

GImageView is a GTK+ based image viewer. It supports tabbed browsing, thumbnail table views, directory tree views, drag and drop, reading thumbnail cache of other famous image viewers, and a flexible user interface.

Gimmage is a simple image viewer that aims to have a minimalist interface and tries to be keyboard operable for browsing through a large number of images quickly. It is appropriate for command line usage as it accepts directories and image filenames as arguments. It has an in-application file browser that allows users to select and drag images and directories into the image viewing area in order to have them displayed.

This is a collection of additional data files for GIMP 2.0. It adds a couple of brushes and patterns to the set of files that are already shipped with the GIMP tarball.

G'MIC stands for GREYC's Magic Image Converter. This project aims to: * Define a minimal but powerful script language (G'MIC) dedicated to the design of image processing pipelines. * Provide an interpreter of this language (in C++), distributed as an open-source module/library embeddable in third-party applications. * Propose two binary tools embedding this interpreter : o The command-line executable gmic to use the G'MIC framework from a shell. o The interactive plug-in gmic_gimp to bring G'MIC capabilities to the image retouching software GIMP.

The meta port for GIMP User Manual which consists of HTML pages in several languages for use with the internal GIMP help browser or any web browser.

The Liquid Rescale plugin is an implementation of the content-aware resizing by seam carving algorithm by Shai Avidan and Ariel Shamir. It aims at resizing pictures non uniformly while preserving the features of the picture, i.e. avoiding distortion of the important parts of the picture. It can also be used to remove portions of the picture in a consistent way. It works both ways, but enlarging gives better results if done in successive steps. It can use extra layers as masks to select which features of the image should be preserved and which should be discarded. The plugin works on the active layer or floating selection. If a selection is present, it is saved to a channel. If the layer has a transparency mask, an option is given to select the behaviour (apply/discard).

Gcolor is a very simple color picker that can be used to pick precise colors. It was inspired as a replacement for xcolorsel that offers a wider band of colors to pick from.

Gcolor2 is a simple, standalone GTK+ 2.0 color selector.

[ edited excerpt from developer's www site ] During image processing operations such as scanning and scaling, images tend to get blurry. The blurred impression of these images is due to the fact that image pixels are averaged with their neighbors. Blurred images don't have sharp boundaries and look as though they have been taken with an unfocussed camera. Refocus is a GIMP plug-in to "refocus" the image, using a technique called FIR Wiener filtering. The traditional technique for sharpening images is to use unsharp masking. Refocus generally produces better results than unsharp masking. The plugin can be found under "Filters > Enhance > Refocus"
