# This sample Python script illustrates how to DICOM-ize a JPEG image,
# a PNG image, or a PDF file using the route "/tools/create-dicom" of
# the REST API of Orthanc. Make sure to adapt the parameters of the
# DICOM-ization below.
#
# The following command-line will install the required library:
#
#  $ sudo pip3 install requests
