Question: Can I draw somthing in screen coordinates instead of geographic?

I am trying to create a Wind Arrow for Falcon View 4.0.1.1076. This arrow needs to be displayed in a corner on Falcon View as an overlay. The arrow will never have any Lat/Lon values only an x y coordinates. It needs to be able to change direction based on the direction the wind is moving. The wind direction information will be provided by the aircraft.

Environment

FalconView Version: FalconView 4.0.1
Interface: ILayer3

Answer

Look at ILayerEditor3. It is a lowere level interface added in FV 4.x that always draws in screenspace. There is a sample project on the page that draws a compass rose in the upper right corner of the screen.
