_Reported by Markus Daniel Herrmann on 2019-04-16:_

I stumbled upon an issue with the OrthancWSIDicomizer program that I would like to bring to your attention.

When converting an SVS file to DICOM VL Whole Slide Microscopy Image instances, all resulting image instances have the same value for the PixelSpacing attribute, independent of the pyramid level. This occurs with “--pyramid=on” and “--pyramid=off”.

It seems spacing is computed only upon setup and not updated later on for subsequent images (pyramid levels): https://hg.orthanc-server.com/orthanc-wsi/file/8c279c5b28a3ee2057a051c0117a336136a276f2/Applications/Dicomizer.cpp
