How to apply ROPs (Raster Operation) when drawing with GDI+ and do we need to use ROPs with GDI+?

I am doing drawing image to EMF file using GDI+ however I don't see any function of GDI+ related to ROPs. I understand that GDI+ is designed with object oriented thinking and supports high quality graphics. So do we need ROPs when using GDI+?

For more details you could refer to the Doc:Interoperability between GDI and GDI+
