canvas-fit 

Small module for fitting a canvas element within the bounds of its parent.
Useful, for example, for making a canvas fill the screen. Works with SVG
elements too!

Usage


$3

Creates a resize function for your canvas element. Calling this function
will resize the canvas to fit its parent element.

Here's a simple example to make your canvas update its dimensions when
resizing the window:

`` javascript
var fit = require('canvas-fit')
var canvas = document.createElement('canvas')

window.addEventListener('resize', fit(canvas), false)
`

You might want to override the parent element that the canvas should be
fitting within: in which case, pass that element in as your second argument:

` javascript
window.addEventListener('resize'
, fit(canvas, window)
, false
)
`

You can also set the scale of the canvas element relative to its styled size
on the page using the scale argument – for example, passing in
window.devicePixelRatio here will scale the canvas resolution up on retina
displays.

$3

Dynamically change the canvas' target scale. Note that you still need to
manually trigger a resize after doing this.

$3

Dynamically change the canvas' parent element. Note that you still need
to manually trigger a resize after doing this.

$3

Instead of filling a given element, explicitly set the width and height
of the canvas. Note that this value will still be scaled up according
to resize.scale

` javascript
resize.parent = function() {
return [ window.innerWidth - 300, window.innerHeight ]
}
``
