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)
