Capture viewport with a different display mode

Hello,

Can we capture a viewport with a chosen display mode without selecting it in the viewport, like in zbuffer?

SetDisplayMode

@rajaa - can you help with this?

Hi @seg You can pick different view, but you cannot pick different display mode from within the view capture dialog in the command. Is that what you are asking about?

Thanks @rajaa
Yes, but it looks is not available
I use this way:

// Change to lineart display mode 1
view.ActiveViewport.DisplayMode = Rhino.Display.DisplayModeDescription.GetDisplayMode(lineartdisplay);
view.Redraw();

System.Windows.Forms.Application.DoEvents();

// Capture lineart image
lineart = view_capture.CaptureToBitmap(view);

// Change to lineart display mode 2
view.ActiveViewport.DisplayMode = Rhino.Display.DisplayModeDescription.GetDisplayMode(segdisplay);
view.Redraw();

System.Windows.Forms.Application.DoEvents();

// Capture segmented image
segimage = view_capture.CaptureToBitmap(view);

But like in ZBufferCapture.SetDisplayMode will be better

ZBufferCapture depth = new ZBufferCapture(view.ActiveViewport);
depth.SetDisplayMode(currentGuid);
zbuffer = depth.GrayscaleDib();
resultpictureBox.Image = zbuffer;
depth.Dispose();

@jeff can you help?

Hi @rajaa
This code works perfect

 private void RunScript(List<string> displays, bool capture, ref object A)
  {
    var doc = Rhino.RhinoDoc.ActiveDoc;
    var view = doc.Views.ActiveView;
    var currentdisplay = view.ActiveViewport.DisplayMode;
    if(capture)
    {
      images.Clear();
      foreach(var d in displays)
      {
        Capture(view, d, currentdisplay);
      }
    }
    A = images;
  }

  // <Custom additional code> 
  List<Bitmap> images = new List<Bitmap>();
  void Capture(RhinoView view, string display, DisplayModeDescription current)
  {
    Rhino.Display.DisplayModeDescription targetDisplay = Rhino.Display.DisplayModeDescription.FindByName(display);

    if (view == null) return;
    if (targetDisplay == null) return;
    view.ActiveViewport.DisplayMode = targetDisplay;
    Bitmap bitmap = view.CaptureToBitmap(targetDisplay);
    if(bitmap != null)
    {
      images.Add(bitmap);
    }
    view.ActiveViewport.DisplayMode = current;
    doc.Views.Redraw();
  }

So is there still a question here? Looks like you’ve got everything working.

Hi! I have a question regarding the bitmap preview component. Could you please tell me which one you are using?

This is from my plugin Wizzard , but it is not available now in food4rhino until i fix some other components

I see, looks nice (minimalistic and informative). Will try it once available
