**

> Parameters
|
||
**
|
||
- container (HTMLElement|string) DOM element or its ID which is going to be a parent for drawing surface
|
||
- width (number)
|
||
- height (number)
|
||
- callback (function) #optional callback function which is going to be executed in the context of newly created paper
|
||
* or
|
||
- x (number)
|
||
- y (number)
|
||
- width (number)
|
||
- height (number)
|
||
- callback (function) #optional callback function which is going to be executed in the context of newly created paper
|
||
* or
|
||
- all (array) (first 3 or 4 elements in the array are equal to [containerID, width, height] or [x, y, width, height]. The rest are element descriptions in format {type: type, <attributes>}). See @Paper.add.
|
||
- callback (function) #optional callback function which is going to be executed in the context of newly created paper
|
||
* or
|
||
- onReadyCallback (function) function that is going to be called on DOM ready event. You can also subscribe to this event via Eve’s “DOMLoad” event. In this case method returns `undefined`.
