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]
|
|
||||||
* `go get github.com/llgcode/draw2d/draw2d`
|
|
||||||
|
|
||||||
a good starting point is the [http://github.com/llgcode/draw2d/wiki/GettingStarted getting started]

======
|
||||||
|
|
||||||
|
This package (written in [go](http://golang.org)) provides an API to draw 2d geometrical forms on [images](http://golang.org/pkg/image).
|
||||||
|
This library is largely inspired by [postscript](http://www.tailrecursive.org/postscript), [cairo](http://cairographics.org) and [HTML5 canvas](http://dev.w3.org/html5/canvas-api/canvas-2d-api.html#the-2d-drawing-context).
|
||||||
|
|
||||||
|
The package depends on [freetype-go](http://code.google.com/p/freetype-go) package for its rasterization algorithm.
|
||||||
|
|
||||||
|
Some algorithms have been translated from the [antigrain.com](http://www.antigrain.com) project ([adaptive bezier](http://www.antigrain.com/research/adaptive_bezier/index.html), and arc drawing.)
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
Once you have Go installed, to install `draw2d`:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
$ go get github.com/llgcode/draw2d/draw2d
|
||||||
|
```
|
||||||
|
|
||||||
|
a good starting point is the [getting started](http://github.com/llgcode/draw2d/wiki/GettingStarted) wiki page.
