[ITK] [ITK-users] Connecting multiframe dicom file to VTK

[Marcos]

Hi Matt,

yes, otherwise I guess I couldn't see anything:

con->SetInput(itkImage);

con->Update();


imageData->DeepCopy(con->GetOutput());

imageViewer->SetInputData(imageData);

imageViewer->GetRenderer()->ResetCamera();


// some renderwindow and interactor settings for the widget


widget->update()



I'd like to change frames, but I guess I'm sending just one frame.

Also, I can't find an example from ITK to access each frame. If I
can't set a pipeline so I can do it from VTK, maybe I can read a slice
in ITK when I need it and pass that frame through the connector and
update.


Maybe I shouldn't use an itk::ImageFileReader, I don't know.
