Save position of the nodes of DiagramView

I have a DiagramView with BackgroundImage, and on this image/document the user draws transparent rectangles to locate areas of the document.

diagramView.Behavior = Behavior.DrawShapes;
diagram.DefaultShape = Shapes.Rectangle;
diagramView.Diagram.ShapeNodeStyle.Brush = new MindFusion.Drawing.SolidBrush(Color.Transparent);
diagramView.Diagram.DiagramStyle.ShadowBrush = new MindFusion.Drawing.SolidBrush(Color.Transparent);


diagram.BackgroundImage = Image.FromFile("e:\\temp\\invoice.tiff");
diagram.Invalidate();

It is possible save only the position of nodes (rectangles) (without image) but display image + nodes?? (diagramView.SaveToFile, diagramView.SaveToStream????)


Thanks in advance

You could temporarily set BackgroundImage to null before calling a SaveTo* method to avoid saving it. Alternatively, do not set that property at all, but call e.Graphics.DrawImage from a DrawBackground event handler to draw the background.

I hope that helps,
Stoyan
