示例1: GetBoundsExample
Public Sub GetBoundsExample(ByVal e As PaintEventArgs)
' Create a GraphicsPath and add an ellipse to it.
Dim myPath As New GraphicsPath
Dim ellipseRect As New Rectangle(20, 20, 100, 100)
myPath.AddEllipse(ellipseRect)
' Fill the path with blue and draw it to the screen.
Dim myBrush As New SolidBrush(Color.Blue)
e.Graphics.FillPath(myBrush, myPath)
' Create a region using the GraphicsPath.
Dim myRegion As New [Region](myPath)
' Get the bounding rectangle for myRegion and draw it to the
' screen in Red.
Dim boundsRect As RectangleF = myRegion.GetBounds(e.Graphics)
