获得一组拉斐尔物体的BBox？(Get BBox of a GROUP of Raphael objects?)

获得一组拉斐尔物体的BBox？(Get BBox of a GROUP of Raphael objects?)

获得几个拉斐尔物体整体的边界框的最好方法是什么？

我可以把它们放在一个set并调用mySet.getBBox() ？

或者我需要循环遍历它们，为每一个获得bbox并计算总体高度和宽度？

（另外，我不能直接使用SVG - 我需要VML支持。）

What's the best way to get the bounding box of several Raphael objects as a whole?

Can I put them all in a set and call mySet.getBBox()?

Or do I need to loop through them all, get bbox for each one and calculate the overall height and width?

(Also, I can't use SVG directly - I need VML support.)

呃。 这很容易。 （谢谢@Dylan）：

var paper = Raphael ('test', 100, 100); var circles = paper.set(); var c1 = (70,0,10); var c2 = (50,10,10); var c = (10,80,10); circles.push(c1, c2, c); alert(c.getBBox().width); // --> 20 alert(circles.getBBox().width); // --> 80

Uh. It's really easy. (Thanks @Dylan):

var paper = Raphael ('test', 100, 100); var circles = paper.set(); var c1 = (70,0,10); var c2 = (50,10,10); var c = (10,80,10); circles.push(c1, c2, c); alert(c.getBBox().width); // --> 20 alert(circles.getBBox().width); // --> 80
