The OpenJPEG library is an open-source JPEG 2000 library developed in order to promote the use of JPEG 2000. The main part of the project consists in a JPEG 2000 codec compliant with the Part 1 of the standard (Class-1 Profile-1 compliance). Besides this main codec, OpenJPEG integrates several other modules: - JP2 (JPEG 2000 standard Part 2 - Handling of JP2 boxes and extended multiple component transforms for multispectral and hyperspectral imagery) - MJ2 (JPEG 2000 standard Part 3) - JPWL (JPEG 2000 standard Part 11) - JPIP (JPEG 2000 standard Part 9) - OPJViewer, a GUI viewer for J2K, JP2, JPWL and MJ2 files

SpringGraph.pm is a rewrite of the springgraph.pl script, which provides similar functionality to Neato and can read some/most dot files. The goal of this module is to provide a compatible interface to VCG and/or GraphViz perl modules on CPAN. This module will also provide some extra features to provide more flexibility and power. This module is still experimental and is moving quickly away from the original springgraph.pl code. It is likely to be rewritten from basic principles in the near future to remove some of the quirks inherent in the Autodia and springgraph.pl code used.

PyOpenGL is an interface between the Python programming language and the OpenGL library (and related libraries). The package provides interfaces to: - The OpenGL library itself, which is a three-dimensional graphical rendering interface. For more information, visit http://www.opengl.org. - The GLU library which provides access to routines for doing quadrics, tesselation etc. - The GLUT (GL UTilitity) library from Mark Kilgard, which provides a windowing environment. - The Togl (Tk/OpenGL) widget from Brian Paul and Ben Benderson (an alternative to GLUT which interfaces to Tk). The Python bindings offer some value-added tools in addition to the standard API, including support for fast processing of arrays of coordinates, trackball support, etc.

PyX is a Python package for the creation of encapsulated PostScript figures. It provides both an abstraction of PostScript and a TeX/LaTeX interface. Complex tasks like 2d and 3d plots in publication-ready quality are built out of these primitives. Features * PostScript output for device independent, free scalable figures * seamless TeX/LaTeX integration * full access to PostScript features like paths, linestyles, fill patterns, transformations, clipping, etc. * advanced geometric operations on paths like intersections, transformations, splitting, etc. * sophisticated graph generation: modular design, pluggable axes, axes partitioning based on rational number arithmetics, flexible graph styles, etc.

pngquant is a command-line utility to quantize and dither 32-bit RGBA PNGs down to 8-bit (or smaller) RGBA-palette PNGs, usually with a significant reduction in file size (40-70% smaller than 24-bit PNGs). This unique type of PNG supports full alpha transparency and is compatible with all modern web browsers, and has better fallback in IE6 than 24-bit PNGs. Features: - High-quality palette generation using modernized Median Cut algorithm. - Unique dithering algorithm that adds less noise to images than the standard Floyd-Steinberg. - Easy to integrate with shell scripts, GUIs and server-side software. - Fast mode for processing large numbers of images.

The VCG tool reads a textual and readable specification of a graph and visualizes the graph. If not all positions of nodes are fixed, the tool layouts the graph using several heuristics as reducing the number of crossings, minimizing the size of edges, centering of nodes. The specification language of the VCG tool is nearly compatible to GRL, the language of the edge tool, but contains many extensions. The VCG tool allows folding of dynamically or statically specified regions of the graph. It uses colors and runs on X11. (An older version runs on Sunview).

Rawstudio is an open-source program to read and manipulate RAW images from digital cameras. It will convert your RAW files into JPEG, PNG, or TIFF images which you can then print or send to friends and clients. You can also upload photos directly to Picasa, Flickr, and Facebook galleries. Rawstudio is intended to be the first tool in your image processing chain. After you have made your overall image adjustments to your image, you can use an image editing application to further work on your images. Rawstudio itself is a highly specialized application for reviewing and processing RAW images, not a fully featured image editing application.

RenRot is utility written in Perl, aiming to carry out different processing tasks upon the image files (especially those containing EXIF data). RenRot renames files according to the flexible name template (allowing the DateTimeOriginal and FileModifyDate EXIF tags, if they exist, otherwise, the name will be set according to the current time stamp). Furthermore, RenRot can aggregate files according to the shooting time period. Additionally, it can losslessly rotate JPEGs and their thumbnails, based on the Orientation EXIF tag, or a given angle. The script can also put commentary into the Commentary and UserComment tags. Personal details can be specified via XMP tags defined in a configuration file.
