Hello Ingmar,
thank you for your help.
I have a last question. If I add a seed point to one of the
QmitkSliceWidgets and later on I change the view of the image that is shown
in it, will the seed point also appear in the new view of the same image?
And if I do it with VTK, will I see the added actor in every view of the
image (sagittal, coronal...)?
Thank you!
Best regards,
Cristina
