This is a library for OpenGL to load PNG graphics files as an OpenGL texture as easily as possible. It also has a number of options for generating the alpha channel and mipmaps.

libEMF is a C/C++ library which provides a drawing toolkit based on ECMA-234. The general purpose of this library is to create vector graphics files on POSIX systems which can be imported into StarOffice/OpenOffice.

Mapyrus is software for creating plots of points, lines, polygons and labels to PostScript (high resolution, up to A0 paper size), Portable Document Format (PDF), Scalable Vector Graphics (SVG) format and web image output formats.

The openNURBS Initiative provides CAD, CAM, CAE, and computer graphics software developers the tools to accurately transfer 3-D geometry between applications. openNURBS is an open source toolkit for reading and writing models in the 3DM format

Radius Engine is a Lua script-based real-time 2D graphics engine designed for rapidly prototyping games. Built on top of SDL and OpenGL, games made with Radius Engine are portable to both Windows and Linux.

A SANE scanner backend for various Epson scanners. This backend supports many more devices than the sane-epson included in graphics/sane-backends, including new multifunction devices such as the SX400.

The purpose of this library is to simplify the creation of computer graphics software. Specifically, it is targeted towards cross-platform development using the OpenGL rendering API and the FLTK interface toolkit. It attempts to provide facilities which are useful in the majority of graphics programs. This release introduces some (relatively small) incompatible changes with 1.0.x versions of the library. Details on changes can be found below.

Gromit (GRaphics Over MIscellaneous Things) is a small tool to make annotations on the screen. When making presentations of the Gimp I found myself often moving the mousepointer around the point of interest until hopefully everybody noticed it. This annoyed me, since it is a very vague way to highlight something. I dreamt of a small programm which allows me to simply draw on the screen, ignoring any window-borders.

Open Inventor(TM) is an object-oriented 3D toolkit offering a comprehensive solution to interactive graphics programming problems. It presents a programming model based on a 3D scene database that dramatically simplifies graphics programming. It includes a rich set of objects such as cubes, polygons, text, materials, cameras, lights, trackballs, handle boxes, 3D viewers, and editors that speed up your programming time and extend your 3D programming capabilities. Open Inventor: - is built on top of OpenGL (R) - defines a standard file format for 3D data interchange - introduces a simple event model for 3D interaction - provides animation objects called Engines - provides high performance object picking - is window system and platform independent - is a cross-platform 3D graphics development system - supports PostScript printing - encourages programmers to create new customized objects - is fun to use

The Graphics Transformation Languages is a set of libraries for using and integrating transformation algorithms (such as filter or color conversion) in graphics applications. The goal is to provide the tools, languages and libraries to create generic transformation for graphics. Those transformations could then be used by different programs (Krita, The Gimp, CinePaint, gegl...). Currently the focus is on developing two languages, designed for two different implementations. - OpenCTL which is a GPL compatible of the Color Transformation Language, this language is dedicated at transforming the value of a single pixel (for instance brightness adjustement or desaturate). CTL is designed to be part of the Color Management process. - OpenShiva is inspired by Adobe's Hydra language from the AIF Toolkit, Shiva is a language that apply a kernel-like transformations on an image, that means it works using more than one pixel.
