I got a problem with localtoglobal. Suppose I have a canvas
wihch is set as global canvas A. I set another canvas inside A as
component, say B. And I set a canvas inside B as component, say C.
Now I draw a point in C, and I want to get the x and y value of
this point in the coordinates of B.
In the B, if I use localtoglobal, it return the x and y value
in the coordinates of A wihch is lager than B`s boundary. If I use
localtocontent, it return the x and y value in the coordinates of
C. So How could I get the value I want? Thanks you guys.
BTW, how to post a pic here, I know it can tell you what I
