[vtkusers] vtkImageData and pipelines

[Craig Henderson]

Hi,

I asked this last week, but didn't get any response. I haven't been able to solve the problem so thought I'd try the list again.

I am trying to use the reslicing classes, based on the example in Examples\GUI\Qt\FourPaneViewer, although I am not using QT.

 I have this code,

vtkSmartPointer<vtkImageData> image;

// image creation code snipped

auto riw = vtkSmartPointer<vtkResliceImageViewer>::New();

riw->SetRenderWindow(render_window_->GetRenderWindow());

riw->SetupInteractor(vtkSmartPointer<vtkRenderWindowInteractor>::New());

riw->SetResliceCursor(riw[0]->GetResliceCursor());

rep->GetResliceCursorActor()->GetCursorAlgorithm()->SetReslicePlaneNormal(i);

riw->SetInput(image);

riw->SetSliceOrientation(0);

riw->SetResliceModeToAxisAligned();

 

This fails on the penultimate line, the call to SetSliceOrientation(), and seems to be because I have set the Input directly and the library is expecting a pipeline algorithm.

Is this the case, and can anyone please suggest how to overcome this? Is there a pipeline algorithm to feed vtkImageData in a call to SetInputConnection() or is that the wrong route?

 

Here's my call stack; note the inPtr is NULL calling into vtkImageMapperConvertImageScalarsToRGBA() and beyond:
