DrawAreaCore(IEnumerable<ScreenPointF［］>, GeoPen, GeoBrush, DrawingLevel, Single, Single, PenBrushDrawingOrder)
This method draws an area on the GeoCanvas.
Remarks
This method is used to draw on the GeoCanvas. It provides you with a number of overloads that allow you to control how things are drawn. Specify the GeoBrush to fill in an area. Specify the GeoPen to outline an area using that GeoPen. You can also call an overload that will allow you to specify both a GeoPen and a GeoBrush.
The DrawingLevel allows you to specify the level you will draw on when you are drawing multiple areas. This is very useful when you want to draw a drop shadow, for example. In that case, you could draw the black backdrop on the lowest level with an offset, then draw the normal shape on a higher level without an offset.
