I am trying to place a PictureMarkerSymbol with a given rotation angle on to of line objects with a given slope. Objective is to place the PictureMarkerSymbol orthogonally to the axis of the line.
So far I did not manage to achieve any effect. Setting the angle attribute of the PictureMarkerSymbol before creating a graphic based on the symbol does not have any effect.
As far as I understand, the ArcGIS for iOS application does show a small arrow from the GPS location to the target while driving. I wonder how it is implemented there without rotating the symbol.
