public void FromAnnObjectToDataSet( 
   DicomDataSet ds,
   AnnObject annObject,
   DicomElement graphicAnnSqItem
)

'Declaration
 
Public Sub FromAnnObjectToDataSet( _
   ByVal ds As DicomDataSet, _
   ByVal annObject As AnnObject, _
   ByVal graphicAnnSqItem As DicomElement _
)

'Usage
 
Dim instance As DicomAnnotationsUtilities
Dim ds As DicomDataSet
Dim annObject As AnnObject
Dim graphicAnnSqItem As DicomElement
 
instance.FromAnnObjectToDataSet(ds, annObject, graphicAnnSqItem)

public void FromAnnObjectToDataSet( 
   DicomDataSet ds,
   AnnObject annObject,
   DicomElement graphicAnnSqItem
)

 function Leadtools.Dicom.Annotations.Core.DicomAnnotationsUtilities.FromAnnObjectToDataSet( 
   ds ,
   annObject ,
   graphicAnnSqItem 
)

public:
void FromAnnObjectToDataSet( 
   DicomDataSet^ ds,
   AnnObject^ annObject,
   DicomElement^ graphicAnnSqItem
)

Parameters

ds: The Leadtools.Dicom.DicomDataSet where the annotation objects will be added.
annObject: The LEAD annotation object that is being converted.
graphicAnnSqItem: Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module". The resulting DICOM annotation objects will be added to the dataset under the item this parameter points to.

This function will automatically add the resulting DICOM annotation objects into the ds. If the resulting DICOM annotation object is a "Compound Graphic " then it will be added under the "Compound Graphic Sequence" under the item the graphicAnnSqItem points to, 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" under the item pointed to by graphicAnnSqItem. If the resulting DICOM annotation object is a "Graphic Object" then it will be added under the "Graphic Object Sequence" under the item pointed to by graphicAnnSqItem.
