HTML Canvas Reference / PDF





                    Sample of the pdf document :  


 


Description:
The HTML5 <canvas> tag is used to draw graphics, on the fly, via scripting (usually JavaScript).
However, the <canvas> element has no drawing abilities of its own (it is only a container for graphics) - you must use a script to actually draw the graphics.

The getContext() method returns an object that provides methods and properties for drawing on the canvas.


This reference will cover the properties and methods of the getContext("2d") object, which can be used to draw text, lines, boxes, circles, and more - on the canvas.





Browser Support:

Internet Explorer 9, Firefox, Opera, Chrome, and Safari support <canvas> and its properties and methods.

Note: Internet Explorer 8 and earlier versions, do not support the <canvas> element.
