I added a PDF using this Orthanc Book bit as reference.
Then on retrieval, starting from a study’s OID I do:
GET "/studies/{oid}" to retrieve a study instance UID
POST to "/tools/find" to query for SeriesDescription and StudyInstanceUID
GET "/series/{serie_oid}" to retrieve the first instance oid
GET "/instances/{instance_oid}/pdf"
Is this “little dance” the proper way to access the PDF data or is there a shorter way?
