Is it possible to change start and end points of subpathes on HTML5 canvas

About HTML5 canvas, I have a question.

Is it possible to change start and end points of subpathes on H开发者_JAVA百科TML5 canvas? I mean, I want to change a shape which I have already drawn by drag & drop.

Thanks in advance, for any tips!

Do you want to do something like that? http://libcanvas.github.com/ui/path-changing.html

It is not so ease, you should do a lot of counts & redraws. The most correct way is to use canvas frameworks.
