FromDataSetToAnnContainer Method

Summary

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

Syntax
C#
C++/CLI
public AnnContainer FromDataSetToAnnContainer( 
   DicomDataSet ds, 
   DicomElement graphicAnnSqItem 
) 
public: 
AnnContainer^ FromDataSetToAnnContainer(  
   DicomDataSet^ ds, 
   DicomElement^ graphicAnnSqItem 
)  

Parameters

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

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

Return Value

A LEAD Leadtools.Annotations.Engine.AnnContainer that contains LEAD Leadtools.Annotations.Engine.AnnObject.

Remarks

This method takes Leadtools.Dicom.DicomDataSet as input, and converts all of the DICOM annotations stored in the Graphic Annotation Sequence into LEAD annotations. The LEAD annotations are returned as a Leadtools.Annotations.Engine.AnnContainer. Note that this method preserves any ruler calibrations, as the ruler calibration is stored in the Leadtools.Annotations.Engine.AnnContainer.
