How to: Use Clipping with a Region
One of the properties of the xref:System.Drawing.Graphics class is the clip region. All drawing done by a given xref:System.Drawing.Graphics object is restricted to the clip region of that xref:System.Drawing.Graphics object. You can set the clip region by calling the xref:System.Drawing.Graphics.SetClip%2A method.
Example
The following example constructs a path that consists of a single polygon. Then the code constructs a region, based on that path. The region is passed to the xref:System.Drawing.Graphics.SetClip%2A method of a xref:System.Drawing.Graphics object, and then two strings are drawn.
The following illustration shows the clipped strings:

Compiling the Code
The preceding example is designed for use with Windows Forms, and it requires xref:System.Windows.Forms.PaintEventArgs e, which is a parameter of xref:System.Windows.Forms.PaintEventHandler.
