Setting a clipping Region

[PaulStat]

I'm trying to use the SetClip method of the Graphics object, Like so

 

public void ClipDCToRect(Region r)
{
               ClippingRegion.Complement(r);
gfx.SetClip(ClippingRegion);
RegionValid = true;
}

 

But I keep getting the following error

 

\CSurface.cs(53): Argument '1': cannot convert from 'System.Drawing.Region' to 'System.Drawing.Graphics'

 

Any ideas??

Only Graphics objects or Rectangle is accepted alone in the overloads, only the last overload accepts a Region but also another argument, CombineMode.
