Flipping and rotating is always done on pixel level. The relevant DICOM tags can be found in the following table:

2.2.1.3.1.3.2Storage Commitment Push Model SOP Class (1.2.840.10008.1.20.1)

When the Storage Commitment Push Model has been configured, the DICOM Store AE will request storage commitment for instances of the Image Storage SOP Class and Grayscale Softcopy Presentation State Storage SOP Class with each successfully completed “sent” job. The DICOM Store AE transmits the SOP Instances to the Remote AE. The request for storage commitment is transmitted to the Remote AE together with a list of references to one or more SOP Instances. If the Provider accepts the Storage Commitment with Success Status, the generated Transaction UID, together with study identification data and a time-stamp, is kept. Success or failure of storage commitment is subsequently indicated by a notification from the Remote AE to "Workstation".

The DIMSE-N Services applicable to the Storage Commitment Push Model SOP Class are:

ØN-EVENT_REPORT

ØN-ACTION

The Storage Commitment Request operation allows a DICOM Store AE to request an SCP to commit to the safekeeping of a set of SOP Instances as described above. This operation is invoked through the N-ACTION primitive.

The N-ACTION is invoked by "Workstation" and is sent by creating a new association.

The behavior of Storage AE when encountering status codes in an N-ACTION response is summarized in the Table below:
