Raphael center of scale in transform method

问题

Right now I'm using:

r.forEach(
    function (el) {
      el.scale(0.5, 0.5, 0.0, 0.0);
    });

to scale each object around (0/0), which is working fine.

The Raphael reference however states that the scale function is deprecated and I'm supposed to use Raphael.transform(...) instead.

I tried:

r.forEach(
    function (el) {
      el.transform("S(0.5)");
    });

however, this will scale the paths using the image center as the center of scale. How can I achieve the same effect with the transform function?

回答1:

You can use translation string the same way as parameters of "scale" function:

el.transform("s0.5, 0.5, 0, 0");

回答2:

el.transform("S0.5, 0.5, 0, 0");

solved here
