FromAnnObjectToDataSet Method

Converts a LEAD Annotation object into one or more DICOM annotation objects, and adds the new DICOM annotation objects into the dataset.

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

  
Public Sub FromAnnObjectToDataSet( _ 
   ByVal ds As Leadtools.Dicom.DicomDataSet, _ 
   ByVal annObject As Leadtools.Annotations.Core.AnnObject, _ 
   ByVal graphicAnnSqItem As Leadtools.Dicom.DicomElement _ 
)  

public: 
void FromAnnObjectToDataSet(  
   Leadtools.Dicom.DicomDataSet^ ds, 
   Leadtools.Annotations.Core.AnnObject^ annObject, 
   Leadtools.Dicom.DicomElement^ graphicAnnSqItem 
)  

Parameters

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.

This example does the following:

1. Creates a LEAD Leadtools.Annotations.Core.AnnProtractorObject
2. Creates a converter
3. Converts the LEAD Leadtools.Annotations.Core.AnnProtractorObject to two grouped Leadtools.Dicom.DicomAnnotationObject, and stores in a Leadtools.Dicom.DicomDataSet
