[ITK-users] Conceptual Question regarding ResampleImageFilter example

[Ricky Singla]

Hi there,

Just a conceptual question about the Resample Image Filter example, located
here -
http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/ResampleImageFilter


I see that the example creates a 100x100 image, and then resamples it to be
200x200. However, I don't quite understand the purpose of the identity
transform used for the transform type. Why is the identity transform used
here? Wouldn't the same result be obtained without an transform?

Cheers,
Ricky Singla
