ANNOUNCE: Haven - A Functional Vector Graphics Library
Mon, 04 Mar 2002 09:07:42 -0500
I am pleased to announce an experimental release of Haven,
a library for scalable vector graphics in Haskell.
Haven provides a wealth of features, including:
- Data types for common geometric shapes such as rectangles,
ellipses and Bezier curves.
- Composition of arbitrary shapes from sequences of straight
and curved segments.
- Intersection tests and bounds calculations on shapes.
- Cropping of any image by any shape.
- Affine transformations on images and paths.
- Calculation of precise rectangular bounds of shapes and images.
- High quality, anti-aliased rendering.
- Scalable outline fonts.
- Smooth blending of colors (gradients)
- Alpha blending (transparency).
- Fine-grained control of stroke width, join rules and end caps.
- Constructive Area Geometry (CAG) for composing shapes using simple
Haven presents a purely functional API, but is implemented using the
Java2D renderer. For more information on Haven, including examples
and download instructions, please visit the haven web page at:

Unified Makefile structure for Linux and Windows using Cygwin
and GNU make.
