public DicomElement FromAnnContainerToDataSet(DicomDataSet ds,DicomElement graphicAnnotationSequenceItem,AnnContainer annContainer)
ds
The Leadtools.Dicom.DicomDataSet where the resulting DICOM Annotation objects are stored.
graphicAnnotationSequenceItem
The specific Leadtools.Dicom.DicomElement where the resulting DICOM Annotation objects are stored.
annContainer
The Leadtools.Annotations.Engine.AnnContainer that contains a list of Leadtools.Annotations.Engine.AnnObject objects that are to be converted.
A Leadtools.Dicom.DicomElement that represents GraphicAnnotationSequence item that contains the DICOM Annotations.
This function converts a LEAD Leadtools.Annotations.Engine.AnnContainer of Leadtools.Annotations.Engine.AnnObject objects into one or more DICOM annotation objects (text, graphic, and compound graphic), and stores the result in a the specified Graphic Annotation Sequence Item Element inside the ds inside the ds parameter.
If any of the resulting DICOM annotation object is a "Compound Graphic " then it will be added under the "Compound Graphic Sequence" and for backward compatibility (as per the DICOM Specification) it will also be added under the "Graphic Object Sequence".
If the resulting DICOM annotation object is a "Text Object" then it will be added under the "Text Object Sequence".
If the resulting DICOM annotation object is a "Graphic Object" then it will be added under the "Graphic Object Sequence".
Note: when converting a Leadtools.Annotations.Engine.AnnPolyRulerObject, Leadtools.Annotations.Engine.AnnProtractorObject, or Leadtools.Annotations.Engine.AnnCrossProductObject, the result will be one or more 'grouped' Leadtools.Dicom.DicomAnnotationObject objects which have the same Leadtools.Dicom.DicomAnnotationObject.GraphicGroupId. In this case, a corresponding Graphic Group Sequence item (0070,0234) will be inserted into the ds.
This example does the following:
