nDrawingDocument.SizeToContent(nDrawingDocument.AutoBoundsMinSize, nDrawingDocument.AutoBoundsPadding, NFilters.Visible);

After using SizeToContent to size the document on the screen, I couldn't find a way to go back to normal. How to get back to normal after using this command?

I mean reset it to normal the way it was. For instance, by resizing to content, the drawing becomes smaller to fit in the screen. Now I want to reset to normal the way it was at the beginning.
