Hello all,
I want to make the entire contour (formed by all points and corresponding lines) scalable. How is this possible?
It is possible to apply vtkAffineWidget on the contour generated by vtkContourWidget? I have tried by 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 make it a scalable surface?
Thank you!
