ToAnnObject(DicomDataSet,List<IDicomAnnotationObject>) Method

Converts a list of Leadtools.IDicomAnnotationObject into a list of Leadtools.Annotations.Core.AnnObject objects.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public List<AnnObject> ToAnnObject( 
   DicomDataSet ds,
   List<IDicomAnnotationObject> dicomAnnotationObjectList
)

'Declaration
 
Public Overloads Function ToAnnObject( _
   ByVal ds As DicomDataSet, _
   ByVal dicomAnnotationObjectList As List(Of IDicomAnnotationObject) _
) As List(Of AnnObject)

'Usage
 
Dim instance As DicomAnnotationsUtilities
Dim ds As DicomDataSet
Dim dicomAnnotationObjectList As List(Of IDicomAnnotationObject)
Dim value As List(Of AnnObject)
 
value = instance.ToAnnObject(ds, dicomAnnotationObjectList)

public:
List<AnnObject^>^ ToAnnObject( 
   DicomDataSet^ ds,
   List<IDicomAnnotationObject^>^ dicomAnnotationObjectList
)

Parameters

ds: A Leadtools.Dicom.DicomDataSet that contains the Graphic Group Sequence (0070,0234).
dicomAnnotationObjectList: The a list of Leadtools.IDicomAnnotationObject to be converted.

Return Value

A list of Leadtools.Annotations.Core.AnnObject

Remarks

This function converts a list of DICOM Annotation Objects (text, graphic, and compound graphic) Leadtools.IDicomAnnotationObject into a list of LEAD annotation objects (Leadtools.Annotations.Core.AnnObject). Note that dicomAnnotationObjectList can contain Leadtools.IDicomAnnotationObject that are grouped together, to return a single Leadtools.Annotations.Core.AnnObject. For example, the Leadtools.Annotations.Core.AnnPolyRulerObject, Leadtools.Annotations.Core.AnnProtractorObject, and the Leadtools.Annotations.Core.AnnCrossProductObject are all stored as one or more 'grouped' Leadtools.Dicom.DicomCompoundGraphic objects.

Example

This example does the following:

Creates two grouped rulers (Leadtools.Dicom.DicomCompoundGraphic)
Creates a converter
Converts the grouped rulers to a LEAD Leadtools.Annotations.Core.AnnPolyRulerObject
