Hello @prms,

Your understanding of the resampling operation in SimpleITK is incorrect. To understand the concept of images as a spatial object and how resampling is performed, please go over the [fundamental concepts](https://simpleitk.readthedocs.io/en/master/fundamentalConcepts.html) the [Transforms and Resampling](https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks/blob/master/Python/21_Transforms_and_Resampling.ipynb) notebook and the [Data Augmentation](https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks/blob/master/Python/70_Data_Augmentation.ipynb) notebook.
