[vtkusers] FW: Full screen display

[Marchessoux, Cedric]

Dear vtkusers, 

I would like to display in fullscreen mode a 1600x1200 image (bmp) on a
monitor-display with a resolution of 1600x1200. 

I use the following program in a tcl/tk procedure: 
----------------------------------------- 

  # Create the RenderWindow, Renderer and both Actors 
  vtkRenderer ren1 
  vtkRenderWindow renWin 
  renWin AddRenderer ren1 
  vtkRenderWindowInteractor iren 
    iren SetRenderWindow renWin 

  # load in the image 
  vtkBMPReader bmpReader 
  bmpReader SetFileName "result.bmp" 

  vtkImageActor ia 
  ia SetInput [bmpReader GetOutput] 

  # Add the actors to the renderer, set the background and size 
  ren1 AddActor ia 
  ren1 SetBackground 0 0 0 
  renWin SetSize 1600 1200 
  renWin SetFullScreen 1 

  #iren HideCursor 
  iren Initialize 
  iren Disable 
  
  # render the image 
  #iren AddObserver UserEvent {wm deiconify .vtkInteract} 
  renWin Render 

  set cam1 [ren1 GetActiveCamera] 
  $cam1 Zoom 1.699 
  ren1 ResetCameraClippingRange 

  iren Start 
  renWin Render 
----------------------------------------- 

It works but, before to display the image in full screen mode, I display the
image with a smaller size on the screen with black borders (background). I
know it is due to the zoom with the camera and I have to use twice "renWin
Render". Do you know a way how to solve it ?
