Overview

Reference Manual
Examples

Getting started

Creating wrapper

From existing canvas

cq(canvas);

From image

cq(image);

From CSS Selector

cq('#canvas');
cq('.image');

Empty

cq(320, 240);

Fullscreen

cq();

CqWrapper supports all CanvasRenderingContext2D methods and properties by using noSuchMethod.

You can still access the original context and canvas element

cq('#something').canvas;
cq('#something').context;

Clone

Any change done to the wrapper will be applied to the original provided (or created) canvas element. Whenever you want to break the chain reaction and get a fresh copy use .clone() method:

var clone = cq().clone()..setHsl(...);

Appending

If you want to insert your canvas to the document body use the .appendTo() method:

cq(320, 240)..fillStyle = '#00ff00'
            ..fill(0, 0)
            ..appendTo(query('body'));
