Haskell Graphics Libraries

This page is about libraries for dealing with graphics, drawing and graphics file formats. For information about libraries for graphical user interfaces, see GUILibraries.

The Hugs Graphics Library
The Hugs Graphics Library supports 2-dimensional graphics operations, timers, mouse and keyboard actions and multiple windows. It runs on Hugs under both Win32 and X11. An earlier version was used for early prototypes of Fran.
Scalable Vector Graphics for Haskell. Portable, device-independent, resolution-independent library, including support for affine transformations, Bezier curves, fine-grained control of pen attributes, bounds and intersection tests, constructive area geometry, anti-aliased rendering, outline fonts, etc.
Functional Reactive Animation
FRAN is a Haskell library (or "embedded language") for interactive animations with 2D and 3D graphics and sound. It runs on Hugs under Windows 95 and Windows NT, using Win32 graphics (GDI).
An embedded language and highly optimizing compiler for image synthesis and transformation, based on the simple idea of images as functions over infinite, continuous 2D space. The resulting binaries can be used as PhotoShop plugins, embedded in web pages or PowerPoint, or used in an interactive standalone viewer. The compiler contains no domain-specific knowledge, so it's very extensible. See the gallery for visual examples. Currently Windows-only, but ports are encouraged.
Pan# is a slightly re-engineered version of Pan. It uses the same compiler but used the Microsoft .NET framework instead of visual studio, making it easier to install and use. It also has a number of new features added. While Pan is embedded in Haskell, Pan# has its own Haskell-like language built in so there is no need to use other Haskell compilers. Currently Windows-only.
Pancito is a Haskell module for manipulating functional images and then saving them to disk. It was inspired by Pan.
PanTHeon is a cross platform re-implementation of of Pan. It is still in development and will likely undergo many changes in the future.
A cross-platform re-implementation of Pan in Haskell using the wxWidgets GUI library and OpenGL graphics library.
HOpenGL is a Haskell binding for the OpenGL graphics API (GL 1.2.1 / GLU 1.3) and the portable OpenGL utility toolkit GLUT.
Functional Metapost
Functional Metapost is a Haskell binding for MetaPost, the powerful but cumbersome graphics language.
Blobs diagram editor
Blobs is a diagram editor for directed graphs. It is written in Haskell, using the platform-independent GUI toolkit wxHaskell. Blobs is a front-end for drawing and editing graph diagrams.

Graphics File Formats

Functional Specification of the JPEG algorithm, and an Implementation for Free


daVinci binding (via the Internet Archive since 2006-03-22)

A binding to daVinci, an X-Windows based visualization tool for directed graphs.
Gif Writer(via Internet Archive since 10/06/2003)
A simple tool - capable of producing GIF based plots from within Haskell programs. Such plots can be then incorporated into HTML reports, to literate Haskell programs, or to combination of both.
JPEG encoding (This link is dead. Fix it or remove it.)
Written in Gofer.
