FromDataSetToAnnContainer(DicomDataSet,DicomElement,DicomDataSet) Method


Converts all the Graphic Annotation Sequence (DICOM Annotations) stored in a Leadtools.Dicom.DicomDataSet into a LEAD AnnContainer that contains LEAD Leadtools.Annotations.Engine.AnnObject objects.

   AnnContainer^ FromDataSetToAnnContainer( 
      DicomDataSet^ ds, 
      DicomElement^ graphicAnnSqItem, 
      DicomDataSet^ dsImage 



The Leadtools.Dicom.DicomDataSet that contains the Graphic Annotation Sequence (DICOM Annotation) being converted.


Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".


A Leadtools.Dicom.DicomDataSet that contains an image. Only those annotations associated with the SOPInstanceUID of dsImage will be converted. All other annotations will be ignored.

Return Value

A LEAD AnnContainer that contains the LEAD AnnObject.


This method takes Leadtools.Dicom.DicomDataSet as input, and converts all the DICOM annotations stored in the Graphic Annotation Sequence into LEAD annotations.

The LEAD annotations are returned as an AnnContainer.

Note that this method preserves any ruler calibrations, as the ruler calibration is stored in the AnnContainer.

The ds can contain annotations associated with more than one DICOM Image (i.e., SOPInstanceUID). This overload only converts those annotations associated with the SOPInstanceUID of dsImage.

All other annotations will be ignored.
