RenderOptions.EdgeMode Attached Property
Gets or sets the EdgeMode enumeration value for a non-text primitive that determines how its edges are rendered.
Assembly: PresentationCore (in PresentationCore.dll)

Use the attached property to improve rendering performance by specifying that a visual object should be rendered with aliased edges. Text objects are always displayed with anti-aliasing, and are unaffected by setting the edge mode value. When you set the edge mode value of a visual object, all the descendant drawing primitives of the visual object are set to the same edge mode value.
