As mentioned here: https://github.com/MapWindow/MapWinGIS/issues/111
We are using TTF font file to place the symbols as point features. We are unable to rotate the individual symbol because there is a option like 'angle' where we modify it the it is been reflecting for the complete features on the particular layer. So we request you to provide a option where we can update the angle for individual symbol. same as ESRI Environment.
There is and option like Point Feature Ft.Rotate() to rotate individual but it is not working.
