The SDL_gfx library evolved out of the SDL_gfxPrimitives code which provided basic drawing routines such as lines, circles or polygons and SDL_rotozoom which implemented a interpolating rotozoomer for SDL surfaces. The current components of the SDL_gfx library are: - Graphic Primitives (SDL_gfxPrimitves.h) - Rotozoomer (SDL_rotozoom.h) - Framerate control (SDL_framerate.h) - MMX image filters (SDL_imageFilter.h)

Scruffy is a Ruby library for creating great looking graphs and charts. Graphs can be rendered to SVG code or an image. Blend the beauty of Gruff with the SVG capabilities of SVG::Graph, make it super simple and extensible, and you've got Scruffy.

Shared Color Profiles contain ICC profiles from different vendors that are all free, either public domain, CC-BY-SA or CC-BY-ND. These include a Adobe RGB compatible and sRGB compatible, as well as various user or manufacturer supplied profiles.

VIGRA stands for "Vision with Generic Algorithms". It's a novel computer vision library that puts its main emphasize on customizable algorithms and data structures. By using template techniques similar to those in the C++ Standard Template Library, you can easily adapt any VIGRA component to the needs of your application, without thereby giving up execution speed.

xfpovray is a graphical interface to the cool ray tracing program POV-Ray (http://www.povray.org). It is written with the XForms library and supports most of the numerous options of POV-Ray. The interface was developed with POV-Ray version 3.0. Please read the documentation on POV-Ray before using xfpovray, especially if you will be using the animation loop or antialiasing.

Xpdf is a viewer for Portable Document Format (PDF) files. These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software. It can also convert PDF input to ps, text, and info formats; and split out fonts and images.

This extension provides a PHP implementation of the OpenCV library. The extension offers two new functions. In principle, they differ only by their return value. The first returns only the number of faces found on the given image and the other an associative array of their coordinates.

CImg stands for Cool Image: it is simple to use and efficient. . The CImg Library is a free C++ toolkit providing simple classes and functions to load, save, process and display images in your own C++ code. . It is highly portable and fully works on Unix/X11, Windows and MacOS X operating systems. It should compile on other systems as well (eventually without display capabilities). . It consists only of a single header file CImg.h that must be included in your program source. . It contains useful image processing algorithms for loading/saving, resizing/ rotating, filtering, object drawing (text, lines, faces, ellipses,..), etc. . Images are instancied by a class able to represent images up to 4-dimension wide (from 1-D scalar signals to 3-D volumes of vector-valued pixels), with template pixel types. . It depends on a minimal number of libraries: you can compile it with only standard C libraries. No need for exotic libraries and complex dependencies. . Additional features appear with the use of GraphicsMagick: install the GraphicsMagick package to be able to load and save compressed image formats (GIF,BMP,TIF,JPG,PNG,...). . Additional features appear with the use of LAPACK: link your code with the lapack library to be able to compute eigenvalues or eigenvectors of big matrices.

The Hebrew Editor package is intended mostly for Hebrew speaking users for creating and editing Hebrew/English LaTeX documents. This package provides a text (terminal) based word processor (in the spirit of the good-old DOS days word processors) which is extremely LaTeX oriented.
