The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a 100 pixel by 100 pixel rectangle whose upper-left corner is at the coordinate (100, 100).
Creates a region defined by the rectangle.
Sets the clipping region to exclude the rectangular region.
Fills a 300 pixel by 300 pixel rectangle whose upper-left corner is at the coordinate (0, 0) with a solid blue brush.
The result is a blue rectangle with a square region toward its lower-right corner missing.
Public Sub ExcludeClipRectangle(ByVal e As PaintEventArgs) ' Create rectangle for exclusion. Dim excludeRect As New Rectangle(100, 100, 200, 200) ' Set clipping region to exclude rectangle. e.Graphics.ExcludeClip(excludeRect) ' Fill large rectangle to show clipping region. e.Graphics.FillRectangle(New SolidBrush(Color.Blue), 0, 0, _ 300, 300) End Sub
