请问Canvas.arc()的四个点具体是什么,请翻译
Use Arc to draw an elliptically curved line with the current Pen.
The arc traverses the perimeter of an ellipse that is bounded by the points
(X1,Y1) and (X2,Y2). The arc is drawn following the perimeter of the ellipse,
counterclockwise, from the starting point to the ending point. The starting point
is defined by the intersection of the ellipse and a line defined by the center of the
ellipse and (X3,Y3). The ending point is defined by the intersection of the ellipse
and a line defined by the center of the ellipse and (X4, Y4).
