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.

Haven

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 Metapost

Functional Metapost is a Haskell binding for MetaPost, the powerful but cumbersome graphics language.

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).

Pan

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#

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

Pancito is a Haskell module for manipulating functional images and then saving them to disk. It was inspired by Pan.

HOpenGL

HOpenGL is a Haskell binding for the OpenGL graphics API (GL 1.2.1 / GLU 1.3) and the portable OpenGL utility toolkit GLUT.

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

A binding to daVinci, an X-Windows based visualization tool for directed graphs.

Graphics File Formats

Gif Writer(since 10/06/2003: via Internet Archive; this library is no longer available!)

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.
