nah, the drawing stuff isn't that smart yet.
 
for now, the only things you can retrieve are the pixel values for a point, like the getPixel stuff:

which can also be combined with red/green/blue/.. commands for simpler code:

well, if you really wanted to work that way, you could define a class which would draw the shape, and store the coordinates used as variables within the object.
 
for example:
 
Code:

 
 
class TheEllipse {
 
  int x, y, size;
  
  TheEllipse (int ix, int iy, int isize) {
    x = ix;
    y = iy;
    size = isize;
  }
  
  void draw() {
    ellipse(x, y, size, size);
  }
  
}
 
 

 
then you could access the coordinates of the ellipse by using EllipseName.x, and EllipseName.y
