Public Sub CreateOverlayBox( _
ByVal overlay As DicomDataSet, _
ByVal parameters As DicomOverlayBoxParameters _
A DicomDataSet object that contains the Overlay data for the Image Overlay Box to be created. The object is assumed to contain the Overlay Pixel Data Sequence (2040,0020). If this parameter is set to a null reference (Nothing in VB) or if the Sequence is not present, the method will fail.
A DicomOverlayBoxParameters object that specifies the parameters of the Image Overlay Box to be created. The method will fail if this is set to a null reference (Nothing in VB).
Two of the exceptions that can be thrown by this method are:
|DicomExceptionCode.PrintSCUFailureStatus||The response of the Print SCP specifies a Failure status code; no Instance was created.|
|DicomExceptionCode.PrintSCUClassNotSupported||The Basic Print Image Overlay Box SOP Class is not supported on the Association.|
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 CreateOverlayBox is successful, the Image Overlay Box was created successfully, with either a Success or Warning status code in the response of the Print SCP.
The method can be used to create one or more Image Overlay Boxes. Having an Image Overlay Box created, the method GetOverlayBoxInstanceUid can be used to obtain its SOP Instance UID, which in turn can be used to reference the Image Overlay Box from Image Boxes. Refer to the method UpdateImageBox.
The parameter parameters specifies the parameters to be used when creating the Image Overlay Box. The properties OverlayOriginRow and OverlayOriginColumn in the passed object will always be used to specify the Overlay Origin (6000,0050); these can be negative. If a string property, in the passed object, is a null reference (Nothing in VB), then the corresponding Attribute will not be included in the request to the Print SCP. Also, if the property MagnifyToNumberOfColumns is negative, the corresponding Attribute will not be included in the request.
