+# Restricting the Drawing Surface in GDI+
+Clipping involves restricting drawing to a certain rectangle or region. The following illustration shows the string "Hello" clipped to a heart-shaped region.

+  
+## Clipping with Regions  
+ Regions can be constructed from paths, and paths can contain the outlines of strings, so you can use outlined text for clipping. The following illustration shows a set of concentric ellipses clipped to the interior of a string of text.

+ To draw with clipping, create a <xref:System.Drawing.Graphics> object, set its <xref:System.Drawing.Graphics.Clip%2A> property, and then call the drawing methods of that same <xref:System.Drawing.Graphics> object:
