Capture a viewport other than the active viewport

Hello all.
I want to capture an object from the isometric southwest view and my custom display mode, but I don’t want to set it as active view then use CaptureToBitmap() method. because it makes a flash in my viewport and also makes my plugin heavy to run, can I use RhinoViewPort that I have made without setting it as ActiveViewPort?
I’m using C# and rhino 7,
thanks.

Any Ideas?

Hello,

If Perspective were SouthWest, I think the capture could be done as follows.

  var viewName = "Perspective";

  var view = doc.Views.Find(viewName, false);
  var bitmap = view.CaptureToBitmap();

  //  your folder path
  bitmap.Save(@"C:\Temp\capture.png", System.Drawing.Imaging.ImageFormat.Png);

thank you Masaki
but can I define a view Without having it in my views? and use it for capture?
also, can I use named views for CaptureToBitmap?
thank you.

You can make your own viewport.

also, can I use named views for CaptureToBitmap?

Yes.You can call up and capture a saved view from your NamedViewTable.
