RemovePresentationStateImageReference Method

Summary

Removes an item from the "Referenced Image Sequence" under the "Presentation State Module".

Syntax

C++/CLI

Java

public void RemovePresentationStateImageReference( 
   string sopInstanceUID 
)

public void removePresentationStateImageReference(String sopInstanceUID)

public: 
void RemovePresentationStateImageReference(  
   String^ sopInstanceUID 
)

Parameters

sopInstanceUID
Character string that contains the SOP Instance UID of the image to be removed from the IOD.

Remarks

This method removes the reference to an image (SOP instance), by removing the item, which represents that instance under the "Referenced Image Sequence" in the "Presentation State Module".

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void DicomPresStateSample() 
{ 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application

      // We can also load the dataset first and then call AddPresStateImageRefByDS 
      dicomDataset.AddPresentationStateImageReference(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "IMAGE3.dcm"), null, 0); 
 
      // We can also add the presentation state using a stream

      } 
 
      //We can also use FindNextPresStateRefSeriesItem to iterate through all items 
      DicomElement item = dicomDataset.FindFirstPresentationStateReferencedSeriesItem(); 
 
      string imageRefSOPInstanceUID = dicomDataset.GetPresentationStateImageReferenceSOPInstance(item, 0); 
      Debug.Assert(imageRefSOPInstanceUID != null); 
      DicomElement item1 = dicomDataset.GetPresentationStateImageReference(imageRefSOPInstanceUID); 
      Debug.Assert(item1 != null); 
 
      dicomDataset.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "PresentationState.dcm"), DicomDataSetSaveFlags.None); 
   } 
   DicomEngine.Shutdown();
