[vtkusers] vtkImageData transform with vtkImageResample/Reslice

[cameron.palmer at ntnu.no]

You just made me think of it. vtkSmartPointer. I’ve gotten so used to shared_ptr I forget the syntax is slightly different.

Isn’t this correct?
vtkSmartPointer<vtkImageReslice>::New()
NOT
vtkSmartPointer<vtkImageReslice>()

Out of curiosity will this go away in favor of the standard library?

I’ve seen a number of online examples using image reslice and resample that don’t seem to work for me. I simply want to scale the image so resample seems to be the way to go, but I always have trouble with the various Input methods. What is the correct formulation for using vtkImageData as input?

vtkImageData* imageData;
...
auto resample = vtkSmartPointer<vtkImageReslice>();
resample->SetInput(imageData);
...
resample->Update();

Please provide the smallest possible compilable example of what you're trying to do, along with an explanation of what is not working (Is there a compiler error? If so, what is it? Is there a runtime error? Does it crash? If so, where? etc.)

Here is an example of a basic use of vtkImageSlice:
