I think it'd be something like this:

vtkTransform *trans = vtkTransform::New();

trans->SetMatrix(mat);//you would have to have mat ahead of time

vtkTransformFilter *filter = vtkTransformFilter::New();

filter->SetInput(imageData);

filter->SetTransform(trans);

filter->Update();

vtkImageData* Output = filter->GetOutput();


 Can anyone confirm or deny? (I never work with ImageData, always PolyData,
in which case this could be used:

Thanks,

David
