• subpixel text

CGAL provides easy access to efficient and reliable geometric algorithms in the form of a C++ library. CGAL is used in various areas needing geometric computation, such as: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, mesh generation, numerical methods, etc. It provides data structures and algorithms such as triangulations, Voronoi diagrams, polygons, polyhedra, mesh generation, and many more.

This package provides a very basic collection of point, size and rect classes for C++.

Basis Universal is an LDR/HDR GPU compressed texture interchange system supporting transcoding to a large number of GPU texture formats.

This package provides a header only C++11 glTF (GL Transmission Format) 2.0 library.

GL Transmission Format (glTF) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. glTF defines an extensible, common publishing format for 3D content tools and services that streamlines authoring workflows and enables interoperable use of content across the industry.

SuperFamiconv is a converter for tiled graphics, supporting the graphics formats of the SNES, Game Boy Color and PC Engine game consoles. Automated palette selection is supported.

OpenEXR provides the specification and reference implementation of the EXR file format. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases.

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.

Alembic is a computer graphics interchange framework. It distills complex, animated scenes into a set of baked geometric results.

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.

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

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

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

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.

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.

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.

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

This package provides a simple Python interface for the Graphviz graph visualization tool suite.

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.

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.

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