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.

Zathura plugin to view PDF with poppler rendering engine

zathura is a highly customizable and functional PDF viewer based on the poppler rendering library and the gtk+ toolkit. The idea behind zathura is an application that provides a minimalistic and space saving interface as well as an easy usage that mainly focuses on keyboard interaction.

FreeBSD graphics console (VGL) version of the famous Digger game. HISTORY ------- Digger was originally created by Windmill software in 1983 and released as a copy-protected, bootable 5.25" floppy disk for the IBM PC/XT. As it requires a genuine CGA card, it didn't work on modern PCs. In 1998 a new version was created by Andrew Jenner which runs on all PCs with CGA or better and, whilst retaining all the atmosphere and playability of the original, has many new features. In 2000 it was ported to several Unix-like architectures by Maxim Sobolev. Currently it supports FreeBSD, using either VGL or SDL library, and Linux using SDL library.

PyScript is a python module for producing high quality postscript graphics. Rather than use a GUI to draw a picture, the picture is programmed using python and the PyScript objects. Some of the key features are: * All scripting is done in python, which is a high level, easy to learn, well-developed scripting language. * All the objects can be translated, scaled, rotated, ... in fact any affine transformation. * Plain text is automatically kerned. * You can place arbitrary LaTeX expressions on your figures. * You can create your own figure objects, and develop a library of figure primitives. * Output is publication quality.

Tex2im is a simple tool that converts LaTeX formulas into high resolution pixmap graphics for inclusion in text processors or presentations. I encountered the problem that the formulas generated by the editors of common office packages usually were the ugliest part of my scientific presentations; on the other hand I didn't want to use latex for my transparencies. On the latex side I'm aware of the slitex and foiltex packages, nevertheless I consider them to be masochistic. EPS import can be nice, but commonly you get either display or printing problems. Also, often its nice just to copy formulas out of you latex documents.

An emulator for the HP 49g+/50g calculator series. This is an ARM-based emulator (unlike emu48 / debug4x), so it is possible to run hpgcc binaries within the emulator. Skins for both variants of the calculator are included. Known limitations: - Cannot write to port 2. Libraries will eat up your RAM. - HPGCC2/3 SD I/O is unstable.

This is a collection of double-resolution sprites for Endless Sky. These sprites will only be used if: - you have set the "zoom factor" to higher than 100% in the preferences, or - you have a high-DPI monitor.
