11 [ method ]
12 **
13 * Creates a canvas object on which to draw.
14 * You must do this first, as all future calls to drawing methods
15 * from this instance will be bound to this canvas.
16 > Parameters
17 **
18 - container (HTMLElement|string) DOM element or its ID which is going to be a parent for drawing surface
19 - width (number)
20 - height (number)
21 * or
22 - x (number)
23 - y (number)
24 - width (number)
25 - height (number)
26 * or
27 - 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>})
28 * or
29 - 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`.

2524 * Element.transform
2525 [ method ]
2526 **
2527 * Adds transformation to the element which is separate to other attributes,
2528 * i.e. translation doesn’t change `x` or `y` of the rectange. The format
2529 * of transformation string is similar to the path string syntax:
2530 | "t100,100r30,100,100s2,2,100,100r45s1.5"
2531 * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
2532 * scale and `m` is for matrix.
2533 *
2534 * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
2535 * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
2536 * coordinates as optional parameters, the default is the centre point of the element.
2537 * Matrix accepts six parameters.
2538 > Usage
2539 | var el = paper.rect(10, 20, 300, 200);
2540 | // translate 100, 100, rotate 45°, translate -100, 0
2541 | el.transform("t100,100r45t-100,0");
2542 | // if you want you can append or prepend transformations
2543 | el.transform("...t50,50");
2544 | el.transform("s2...");
2545 | // or even wrap
2546 | el.transform("t50,50...t-50-50");
2547 | // to reset transformation call method with empty string
2548 | el.transform("");
2549 | // to get current value call it without parameters
2550 | console.log(el.transform());
