I have a problem inserting an image into an existing assembly using 
ActiViz Kitware VTK 5.8 (for C#).

This is how I defined the actor:

     private vtkImageActor psi_imgActor;
     psi_imgActor = vtkImageActor.New();

In the method Psi_DrawTable_Image, I created the image and stored it as 
a file. I checked the file, it is okay and looks as it should, so that 
is not the problem.

Then I created a vtkBMPReader object and set the input of the actor:

     vtkBMPReader bmpReader = vtkBMPReader.New();
     psi_imgActor.SetPosition(250, 200, 1000);

Finally, I added the actor to the assembly, where assembly3D is a 
variable of type vtkAssembly - I added everything that is visible to 
this assembly, except the 2D stuff (such as texts).

     if (psi_imgActor != null) assembly3D.AddPart(psi_imgActor);

Unfortunately, I do not get to see the image. What's wrong? Where's the 

Thank you in advance.
