README 


This package (written in *[http://golang.org go]*) provide an API to draw 2d geometrical form on [http://golang.org/pkg/image/ images]. 
This library is largely inspired by [http://www.tailrecursive.org/postscript/ postscript], [http://cairographics.org/ cairo], [http://dev.w3.org/html5/canvas-api/canvas-2d-api.html#the-2d-drawing-context HTML5 canvas]. 

The package depends on [http://code.google.com/p/freetype-go/ freetype-go] package thanks to its rasterization algorithm. 

Some algorithm have been translated from http://www.antigrain.com project ([http://www.antigrain.com/research/adaptive_bezier/index.html adaptive bezier], and arc drawing)

=== Installation ====
Once you have Go installed, to install draw2d:

 * First see the installation procedure of [http://code.google.com/p/freetype-go/ freetype-go]
 * goinstall draw2d.googlecode.com/svn/trunk/draw2d/src/pkg/draw2d

a good starting point is the [http://code.google.com/p/draw2d/wiki/GettingStarted getting started]


=== [http://code.google.com/p/draw2d/wiki/Samples Samples] ===
Sample images generated by draw2d (inspired by [http://cairographics.org/samples/ cairo samples]): 
there's already some bugs please refer to [http://code.google.com/p/draw2d/issues/list issue tracking]
