jCanvas Object

jCanvas includes a jCanvas object as part of the jQuery object.

$.jCanvas

The jCanvas object contains the following properties/methods:

• defaults: an object containing jCanvas’s default properties
• extend: a method for extending jCanvas with custom methods.

Overriding jCanvas defaults

If you wish to override any of jCanvas’s default property values, set the properties explicitly or use jQuery’s $.extend:

$.jCanvas.defaults.fromCenter = false;

$.extend($.jCanvas.defaults, {
  fromCenter: false,
  inDegrees: false
});
