RectContainsPoint() public méthode

Determines if the Bounds contains the specified PointF.
If it is already know that the PointF fits on the Line at some location, then this is an inexpensive operation to see if the PointF is within the current Line segment.
public RectContainsPoint ( PointF pt ) : bool
pt Evbpc.Framework.Drawing.PointF The to test.
