MuPDF is a lightweight PDF viewer and toolkit written in portable C. The renderer in MuPDF is tailored for high quality anti-aliased graphics. It renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on screen. MuPDF has a small footprint. A binary that includes the standard Roman fonts is only one megabyte. A build with full CJK support (including an Asian font) is approximately five megabytes. MuPDF has support for all non-interactive PDF 1.7 features, and the toolkit provides a simple API for accessing the internal structures of the PDF document. Example code for navigating interactive links and bookmarks, encrypting PDF files, extracting fonts, images, and searchable text, and rendering pages to image files is provided.

MyPaint is a fast and easy open-source graphics application for digital painters. It lets you focus on the art instead of the program. You work on your canvas with minimum distractions, bringing up the interface only when you need it. MyPaint comes with a large brush collection including charcoal and ink to emulate real media, but the highly configurable brush engine allows you to experiment with your own brushes and with not-quite-natural painting.

Netpbm is a toolkit for conversion of images between a variety of different formats, as well as to allow a few basic image operations. Netpbm is based on the widely spread Pbmplus package (release: 10 Dec 91). On top of that, a lot of improvements and additions have been made. After the latest release of Pbmplus, a lot of additional filters have been circulating on the net. The aim of Netpbm was, to collect these and to turn them into a package. This work has been performed by a group of programmers all over the world.

Non-Uniform Rational B-Splines (NURBS) are parametric functions which can represent any type of curves or surfaces. This C++ library hides the basic mathematics of NURBS, allowing the user to focus on the more challenging parts of their projects. The NURBS++ package includes a matrix library, an image manipulation library, a numerical library and a NURBS library. This library is copyrighted under the terms of the LGPL by its author, Phillipe Lavoie <lavoie@zeus.genie.uottawa.ca>.

OpenCSG is a library that does image-based CSG rendering using OpenGL. OpenCSG is written in C++ and supports most modern graphics hardware. CSG is short for Constructive Solid Geometry and denotes an approach to model complex 3D-shapes using simpler ones. I.e., two shapes can be combined by taking the union of them, by intersecting them, or by subtracting one shape of the other. The most basic shapes, which are not result of such a CSG operation, are called primitives. Primitives must be solid, i.e., they must have a clearly defined interior and exterior. By construction, a CSG shape is also solid then. Image-based CSG rendering (also z-buffer CSG rendering) is a term that denotes algorithms for rendering CSG shapes without an explicit calculation of the geometric boundary of a CSG shape. Such algorithms use frame-buffer settings of the graphics hardware, e.g., the depth and stencil buffer, to compose CSG shapes. OpenCSG implements a variety of those algorithms, namely the Goldfeather algorithm and the SCS algorithm, both of them in several variants.

Darktable is a virtual lighttable and darkroom for photographers: an open source photography workflow application and raw image developer. It manages digital negatives in a database and lets one view them through a zoomable lighttable. It also enables one to develop raw images and enhance them. Darktable tries to fill the gap between many excellent existing free raw converters and image management tools (such as UFRaw or F-Spot). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The user will always be able to interact, even if the full resolution image is not yet loaded. All editing is fully non-destructive and only operates on cached image buffers for display. The full image is only converted during export. The frontend is written in Gtk+/Cairo, the database uses SQLite3, raw image loading is done using libraw and rawspeed, high-dynamic range and standard image formats such as JPEG are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).

gd is a graphics library. It allows your code to quickly draw images complete with lines, arcs, text, multiple colors, cut and paste from other images, and flood fills, and write out the result as a PNG, GIF or JPEG file. This is particularly useful in World Wide Web applications, where PNG, GIF and JPEG are three of the formats accepted for inline images by most browsers. gd does not provide for every possible desirable graphics operation, but version 2.0 does include most frequently requested features, including both truecolor and palette images, resampling (smooth resizing of truecolor images) and so forth.

OpenColorIO (OCIO) is a complete color management solution geared towards motion picture production with an emphasis on visual effects and computer animation.

Data Explorer brings together dynamic computational and rendering tools in a dynamic, programmable framework that enables users to rapidly create visualizations of highly complex data from disparate sources. Data Explorer can be used to add visualization capabilities to existing applications. It is used by companies and institutions for applications in a large variety of visualization fields including computational fluid dynamics, medical imagery, computational chemistry, and engineering analysis. For example, it is currently being used to: * Identify and manage portfolio risk worldwide for a large multinational banking group. * Depict oil-flow simulations to improve drilling success-rates and increase reservoir yields. * Piece together over 5,000 ceiling fragments from a 1,200-year-old temple in Peru. * Help insurance agents identify opportunities to cross-sell product offerings. * Visualize developing weather patterns to improve the accuracy of weather forecasts.

Quick Image Viewer (qiv) is a very small and pretty fast GDK/Imlib2 image viewer. It has such nifty features as: zoom, maxpect, scaledown, screensaver, flip, delete, brightness / contrast / gamma correction, and can also be used to set your X11 background. All from a commandline.
