This package provides encoder/decoder implementation for DEC SIXEL graphics, and some converter programs. SIXEL is one of image formats for terminal imaging introduced by DEC VT series. Its data scheme is represented as a terminal-friendly escape sequence. So if you want to view a SIXEL image file, all you have to do is "cat" it to your terminal.

The libmng library supports decoding, displaying, encoding, and various other manipulations of Multiple-image Network Graphics (MNG) format image files. It uses the zlib(3) compression library, and optionally the JPEG library by the Independant JPEG Group (IJG) and/or lcms (little CMS), a color-management library by Marti Maria Saguar.

This is a Linux/i386 binary port of Cairo. Cairo is a vector graphics library with cross-device output support. Currently supported output targets include the X Window System and in-memory image buffers. PostScript and PDF file output is planned. Cairo is designed to produce identical output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). Cairo provides a stateful user-level API with capabilities similar to the PDF 1.4 imaging model. Cairo provides operations including stroking and filling Bezier cubic splines, transforming and compositing translucent images, and antialiased text rendering.

This module is an attempt to build a general purpose graphing module that is easily modified and expanded. I borrowed most of the API from Martien Verbruggen's GIFgraph module. I liked most of GIFgraph, but I thought it was to difficult to modify, and it was missing a few things that I needed, most notably legends. So I decided to write a new module from scratch, and I've designed it from the bottom up to be easy to modify. Like GIFgraph, Chart::* uses Lincoln Stein's GD module for all of its graphics primitives calls.

A very clean graphic library which can handle gif, pcx, targa, rgb, tiff, pix, ppm, pgm, pbm, raw, rayshade's heightfield, jpeg and do the following function: resampling, blur, sharpening, cut, paste, median filter, histogram equalization and so on...

potrace is a Peter Selinger's GPLed utility for tracing bitmaps - converting them into smooth, scalable images. It accepts as input a bitmap B/W images (PBM, PGM, PPM and BMP formats), and returns encapsulated PostScript (EPS) as the default output. Other output format are available: PS, SVG, Xfig, PGM, PDF and experimental GimpPath. You can create scalable images from scans, such as logos, hand taken notes, etc. The resulting smooth images can then be rendered at any resolution.

ditaa is a small command-line utility written in Java, that can convert diagrams drawn using ascii art ('drawings' that contain characters that resemble lines like | / - ), into proper bitmap graphics.

Coin3D Coin is a 3D graphics library with a C++ Application Programming Interface based on the Open Inventor 2.1 API. Open Inventor, for those who are not familiar with it, is an OpenGL-based, retain-mode, 3D model scene-graph rendering and interaction library, which has become the de facto standard graphics library for 3D visualization and visual simulation software in the scientific and engineering community. New versions are published under the BSD 3-clause license.

Crazy Eddie's GUI System is a free library providing windowing and widgets for graphics APIs / engines where such functionality is not natively available, or severely lacking. The library is object orientated, written in C++, and targeted at games developers who should be spending their time creating great games, not building GUI sub-systems!
