Parameters

overlayBoxInstanceUid

The SOP Instance UID of the Image Overlay Box to be updated. The method will fail if this is a null reference (Nothing in Visual Basic) or if an empty string is specified.

overlay

A DicomDataSet object that contains the Overlay data for the specified Image Overlay Box. The object is assumed to contain the Overlay Pixel Data Sequence (2040,0020); the method will fail if this Sequence is not present. This parameter can be set to a null reference (Nothing in Visual Basic) if the Overlay data is not to be updated.

parameters

A DicomOverlayBoxParameters object that specifies the Image Overlay Box parameters to be updated. This can be set to a null reference (Nothing in Visual Basic) if none of the parameters is to be updated.

updateOverlayOrigin

true to update the Overlay Origin (6000,0050) as determined by the properties DicomOverlayBoxParameters.OverlayOriginRow and DicomOverlayBoxParameters.OverlayOriginColumn in the object specified by parameters (these properties can be negative); otherwise, false. In the latter case, the Attribute will not be included in the request to the Print SCP. If parameters is set to a null reference (Nothing in Visual Basic), updateOverlayOrigin will be ignored.

The method will fail if both overlay and parameters are set to null references (Nothing in Visual Basic).

The Image Overlay Box specified (by the SOP Instance UID) must be an exiting one. Refer to the method Leadtools.Dicom.DicomPrintScu.CreateOverlayBox for creating Image Overlay Boxes.

The method will not return until it receives the response of the Print SCP, or an error occurs. The method GetLastOperationStatus can be used to obtain the status code specified in the response of the Print SCP. If the method Leadtools.Dicom.DicomPrintScu.UpdateOverlayBox is successful, the specified Image Overlay Box was updated successfully, with either a Success or Warning status code in the response of the Print SCP.

In the DicomOverlayBoxParameters object specified by the parameter parameters, if a string property is a null reference (Nothing in Visual Basic), then the corresponding Attribute will not be included in the request to the Print SCP and hence will not be updated. Also, if the property DicomOverlayBoxParameters.MagnifyToNumberOfColumns is negative, the corresponding Attribute will not be included in the request and hence will not be updated.
