ToAnnObject(DicomDataSet,List<DicomAnnotationObject>) Method

Summary
Converts a list of Leadtools.Dicom.DicomAnnotationObject into a list of Leadtools.Annotations.Engine.AnnObject objects.
Syntax
C#
C++
vb[VB Syntax] 
  
Public Overloads Function ToAnnObject( _ 
   ByVal _ds_ As DicomDataSet, _ 
   ByVal _dicomAnnotationObjectList_ As List(Of DicomAnnotationObject) _ 
) As List(Of AnnObject) 
public: 
List<AnnObject^>^ ToAnnObject(  
   DicomDataSet^ ds, 
   List<DicomAnnotationObject^>^ dicomAnnotationObjectList 
)  

Parameters

ds
A Leadtools.Dicom.DicomDataSet that contains the Graphic Group Sequence (0070,0234).

dicomAnnotationObjectList
The a list of list of Leadtools.Dicom.DicomAnnotationObject to be converted.

Return Value

A list of Leadtools.Annotations.Engine.AnnObject

Remarks

This function converts a list of DICOM Annotation Objects (text, graphic, and compound graphic) Leadtools.Dicom.DicomAnnotationObject into a list of LEAD annotation objects (Leadtools.Annotations.Engine.AnnObject).

Note that dicomAnnotationObjectList can contain Leadtools.Dicom.DicomAnnotationObject that are grouped together, to return a single Leadtools.Annotations.Engine.AnnObject.

For example, the Leadtools.Annotations.Engine.AnnPolyRulerObject, Leadtools.Annotations.Engine.AnnProtractorObject, and the Leadtools.Annotations.Engine.AnnCrossProductObject are all stored as one or more 'grouped' Leadtools.Dicom.DicomCompoundGraphic objects.

Example

This example does the following:

  1. Creates two grouped rulers (Leadtools.Dicom.DicomCompoundGraphic)
  2. Creates a converter
  3. Converts the grouped rulers to a LEAD Leadtools.Annotations.Engine.AnnPolyRulerObject
