	x As Integer, _
	y As Integer, _
	graphics As Graphics _
) As Boolean


Type: System.Int32

The x-coordinate of the point to test.

Type: System.Int32

The y-coordinate of the point to test.

Type: System.Drawing.Graphics

The Graphics for which to test visibility.

This method returns true if the specified point is contained within this GraphicsPath; otherwise, false.

The coordinates of the point to be tested are given in world coordinates. The transform matrix of graphics is temporarily applied before testing for visibility.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

  • Creates a path and adds an ellipse to the path.

  • Tests whether the specified point is contained within the path.

  • Displays the result in a dialog box.

Public Sub IsVisibleExample(ByVal e As PaintEventArgs)
    Dim myPath As New GraphicsPath
    myPath.AddEllipse(0, 0, 100, 100)
    Dim visible As Boolean = myPath.IsVisible(50, 50, e.Graphics)
End Sub
