Hii everyone
Simple Q: could i instruct Orthanc to compress the incoming Dicom study.
The fourth parameter in Jason file reads
// Enable the transparent compression of the DICOM instances
“StorageCompression” : false,
what would be the outcome if change to “true”. What kind of compression will take place?
Thank you
If “StorageCompression” is set to “true”, all the DICOM instances received by Orthanc will be transparently compressed using zlib.
Thank you Sebastien,
I am experimenting … i have two orthanc instances with and without storage compression . "the download zip " file size of these two instances are identical.
Shouldnt’ i to that the file size from the Orthanc instance that has dicom storage compression set to true to be smaller in size?
onn
by the way. I quite actually love the current robust and reliable version of orthanc with very small foot print on my computer.
Hello,
The “StorageCompression” option is totally transparent to the user, and only affects the way Orthanc internally stores its files on the disk. Nothing can be seen from the outside (except with a reduced disk space).
As a consequence, downloading a ZIP file from Orthanc will lead exactly to the same archive, with or without “StorageCompression.”
HTH,
Sébastien-
Legendary, thank you Sebastien.
I changed config file to this
// Enable the transparent compression of the DICOM instances
“StorageCompression” : true,
But Orthanc still save DICOM file to many file that do not have extension. So what should I do next?
Thank for your help!
As answered in another thread, the “OrthancStorage” directory is private to Orthanc (thus the file extensions within are meaningless) and you should not try and access it directly:
