[Description("Whether or not to render antialiased lines in transparent polygons in a single pass.")]
[DefaultValue(false)]
public bool DoublePassBlending {get; set;}
Remarks
Line antialiasing requires the blending feature of OpenGL to be enabled.
This is why when you have transparent objects (that also use blending) they are
both drawn in the same rendering pass. This sometimes may be undesirable because
the line intensity will not be influences if they are overlapped by a transparent
object. To correct this you may consider to use double pass blending when the
control renders the transparent polygons and lines separately.
Example
The following code turns on the double pass blending:
