2d-context

Grabs a CanvasRenderingContext2D, returning null if it doesn't exist. Similar to webgl-context.

var context = require('2d-context')()
var canvas = context.canvas

or

var canvas = document.createElement('canvas')

var context = require('2d-context')({
    canvas: canvas,
    alpha: true,
    width: 256,
    height: 256    
})

Usage

ctx = require('2d-context')([opt])

Gets a new canvas context with optional parameters:

• canvas a canvas element to use, otherwise creates a new element
• width a width to set, otherwise no change
• height a height to set, otherwise no change
• other attributes are passed to the getContext call, like alpha and storage

You can then get a reference of the canvas element with ctx.canvas.
