The Color Transformation Language, or CTL, is a small programming language that was designed to serve as a building block for digital color management systems. CTL allows users to describe color transforms in a concise and unambiguous way by expressing them as programs. In order to apply a given transform to an image, the color management system instructs a CTL interpreter to load and run the CTL program that describes the transform. The original and the transformed image constitute the CTL program's input and output.

The pstoedit utility allows translating graphics in the PostScript or PDF (Portable Document Format) formats to various other vector formats such as:

• Tgif (.obj)

• gnuplot

• xfig (.fig)

• Flattened PostScript

• DXF, a CAD (Computed-Aided Design) exchange format

• PIC (for troff/groff)

• MetaPost (for usage with TeX/LaTeX)

• LaTeX2e picture

• GNU Metafile (for use with plotutils/libplot)

• Any format supported by ImageMagick

Blender is a 3D graphics creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. The application can be customized via its API for Python scripting.

DirectFB is a graphics library which was designed with embedded systems in mind. It offers maximum hardware accelerated performance at a minimum of resource usage and overhead.

Graphviz is a graph visualization tool suite. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

PyGraphviz is a Python interface to the Graphviz graph layout and visualization package. With PyGraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms.

Library intended to provide a set of useful functions to deal with 3D surfaces meshed with interconnected triangles.

Xdot is an interactive viewer for graphs written in graphviz’s dot language. Internally, it uses the xdot output format as an intermediate format, and gtk and cairo for rendering. Xdot can be used either as a standalone application, or as a Python library.

Pydot provides an interface to create, handle, modify and process graphs in Graphviz's DOT language, written in pure Python.

The purpose of dot2tex is to give graphs generated by Graphviz a more LaTeX friendly look and feel. This is accomplished by converting xdot output from Graphviz to a series of PSTricks or PGF/TikZ commands. This approach allows:

• Typesetting labels with LaTeX, allowing mathematical notation

• Using native PSTricks and PGF/TikZ commands for drawing arrows

• Using backend specific styles to customize the output

This package contains tools for building documentation with Sphinx, Graphviz and LaTeX.

This package provides a Python script to convert the output from many profilers into a dot graph.

It can:

• prune nodes and edges below a certain threshold;

• use an heuristic to propagate time inside mutually recursive functions;

• use color efficiently to draw attention to hot-spots;

• work on any platform where Python and Graphviz is available.

Ronn-NG is an updated fork of ronn. It builds manuals in HTML and Unix man page format from Markdown.

Grap is a language for typesetting graphs specified and first implemented by Brian Kernighan and Jon Bentley at Bell Labs. It is an expressive language for describing graphs and incorporating them in typeset documents. It is implemented as a preprocessor to Kernigan's pic language for describing languages, so any system that can use pic can use grap. For sure, TeX and groff can use it.

Roffit is a program that reads an nroff file and outputs an HTML file. It is typically used to display man pages on a web site.

Groff is a typesetting package that reads plain text and produces formatted output based on formatting commands contained within the text. It is usually the formatter of "man" documentation pages.

Apache Groovy is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform. It integrates smoothly with any Java program, and immediately delivers to your application powerful features, including scripting capabilities, Domain-Specific Language authoring, runtime and compile-time meta-programming and functional programming.

Libntlm is a library that implements NTLM authentication.

GNU SASL is an implementation of the Simple Authentication and Security Layer framework. On network servers such as IMAP or SMTP servers, SASL is used to handle client/server authentication. This package contains both a library and a command-line tool to access the library.

GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio mixing and video non-linear editing.

Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.

This package provides the core library and elements.
