Raphael.ca , the arguments can't not be dynamic?

[vrbvillor]

can I use arguments to override Raphael.ca.something ? Or the argument list of ca must be a certain pattern.

Raphael.ca?

[vrbvillor]

sorry, I made a mistake paper.ca......... Now I write them in Raphael.el, reference the "paper" with "this.paper" to extend the custom attribute..... Though I don't like this way of writing, it seems the only way to extend custom attribute before a certain paper instance is instantiated...

Mistake 2..... this question is to ask the arguments of paper.ca, I answered another question......
