[vtkusers] Problem with resizing an image

[ochampao]

Hi David.

Your first recommendation using vtkImageResize followed by
vtkImageChangeInformation works vert well. Thanks a lot for you help.

For reference, here is my working code:

vtkNew<vtkImageResize> resizeFilter;
resizeFilter->SetResizeMethodToOutputDimensions();
resizeFilter->SetOutputDimensions(image1_dims[0], image1_dims[1], 0);
resizeFilter->InterpolateOn();
resizeFilter->SetInputData(image2);
resizeFilter->Update();

vtkNew<vtkImageChangeInformation> changeFilter;
changeFilter->SetInputConnection(resizeFilter->GetOutputPort());
changeFilter->SetOutputSpacing(image1->GetSpacing());
changeFilter->Update();

Regards,
P.
