[vtkusers] vtkContourWidget and vtkImageViewer2

[Dora Szasz]

It is possible to apply vtkAffineWidget on the contour generated by vtkContourWidget? I have tried, but my contour need to be an actor.

Basically, there is the code for creating the desired contour:

vtkContourWidget *ContourWidget = vtkContourWidget::New();

  vtkOrientedGlyphContourRepresentation *rep = vtkOrientedGlyphContourRepresentation::New(); 
  rep->GetLinesProperty()->SetColor(1, 0, 0);
  ContourWidget->SetRepresentation(rep);
  
  vtkImageActorPointPlacer * imageActorPointPlacer = vtkImageActorPointPlacer::New(); 
  imageActorPointPlacer->SetImageActor(ImageViewer->GetImageActor()); 
  rep->SetPointPlacer(imageActorPointPlacer); 

  imageActorPointPlacer->Delete(); 
  rep->Delete(); 

  ContourWidget->SetInteractor(iren); 
  ContourWidget->SetEnabled(true); 
  ContourWidget->ProcessEventsOn();

How can I use AffineWidget on it?

Have a look at vtkAffineWidget.
