I'm updating a legacy application that uses GDI to plot a large number of points (500k+) in a fraction of a second. I've tried recreating the plotting control in GDI+/C# and the same draw operation takes over 3 seconds, which is unacceptable for the intended application. I believe the difference is due to GDI being hardware accelerated but not GDI+.
What drawing technology should I use to build this control? This application needs to work over terminal server so DirectX is not an option. I would like to write this in C#, is it possible to import the old GDI methods and use them that way? Any tutorials available on how to do this? I could really like to avoid writing the control in C++ and importing it to the application.
Any thoughts?
Thanks
