SYMPTOMS

On a computer that is running Microsoft Windows XP, Microsoft Windows Server 2003, or Windows Vista, you use an exclusionary clipping region in a Graphics Device Interface (GDI+) application. In the application, the right edge or the lower edge of the region can be drawn. However, you expect that these edges cannot be drawn.

This problem occurs if the following conditions are true:
  • The Pen class has an alpha component
  • The value of the alpha component is less than 255.
This problem does not occur when the value of the alpha component is 255.

Note An exclusionary clipping region is a region that cannot be drawn. You can only draw in the area that is outside this region.
