OrthancSeriesProgressiveLoader now has two modes that can be selected at object creation : - progressive (will first load jpeg50, then jpeg90 then PAM) - non-progressive (will directly load PAM (uncompressed)) Please note that the slice loading order remains dynamic and depending upon the slice that the client code wishes to extract from the volume.
