Hello,

Not sure I fully understand the question.

If you are interested in performance, avoid GDI+ totally, and do all
graphics drawing via GDI calls, such as SetPixel. Within .NET, limit GDI+
calls to GetHdc and ReleaseHdc and don't use Antialiasing or alpha channel.

Not sure if GDI+ has a SetPixel counterpart. I've never heard of one.

Generally SetPixel is a slow way of drawing.
