[whatwg] Canvas Path.addPath SVGMatrix not optimal?

[Dirk Schulze]

So can we agree on:

addPath(Path, optional SVGMatrix)

(Independent of the discussion about CanvasPathMethods.)

Does some one think it would be necessary to make SVGMatrix nullable (optional SVGMatrix?)? I think it would be superfluous.

Greetings,
Dirk

Hi,

I just looked at the definition of Path.addPath[1]:

    void addPath(Path path, SVGMatrix? transformation);

SVGMatrix is nullable but can not be omitted all together. Why isn't it optional as well? I think it should be optional, especially because creating an SVGMatrix at the moment means writing:

    var matrix = document.createElementNS('http://www.w3.org/2000/svg','svg').createSVGMatrix();

Agreed, that's painful, +1 for making it optional.
