I need Orthanc to automatically perform compression 1.2.840.10008.1.2.4.57 not only when it receives studies from another PACS or modality, but also when uploading from a local folder.
I have made this configuration in the ORTHANC.JSON file:
However, upon checking the logs in the following image, I understand that it is not compressing. Do you have any suggestions on how to configure it to automatically compress the images upon receiving the studies?
// User-friendly groups of transfer syntaxes that can be enabled or
// disabled at once. These options are applied after the main
// “AcceptedTransferSyntaxes” option has been applied (if present).
“DeflatedTransferSyntaxAccepted” : true,
“JpegTransferSyntaxAccepted” : true,
“Jpeg2000TransferSyntaxAccepted” : true,
“JpegLosslessTransferSyntaxAccepted” : true,
“JpipTransferSyntaxAccepted” : true,

“RleTransferSyntaxAccepted” : true,
“Mpeg4TransferSyntaxAccepted” : true, // New in Orthanc 1.6.0
“H265TransferSyntaxAccepted” : true, // New in Orthanc 1.9.0
Have you tried setting the “IngestTranscoding” configuration ?
