@VladislavAntonyuk Thanks for the response. I'm trying the way you suggested: View: ViewModel: Save signature: Load signature: But in order for this to work as I expect, I need to set the DrawingView Lines Binding to Mode=TwoWay. Whenever I do that, I'm getting this error: The only way I'm not getting this error is by setting my DrawingView Lines Binding to Mode=OneWayToSource. But, if I do that, would not be possible to load the signature from the view model. |

I haven't been able to find a way to go from the Stream back to
