[vtkusers] problem feeding vtkImageData into a pipeline

[Craig Henderson]

Hi,

I am still quite new to VTK and 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 you 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:
