ZoomIn and ZoomOut functions for custom user control(Map) containing gdi geometries

Question

I need to write a code for zoomin, zoomout and pan functions. I have made a usercontrol(Map) to show geometries of a shapefile using GDI technique. Now I need to add some common map functions such as ZoomIn, ZoomOut, FitView and pan etc.

Is there any methods in GDI+ to do such operations?

Anybody, Please Help...

Thanks in advance.
