FromAnnContainerToDataSet(DicomDataSet,AnnContainer) Method

Summary

Converts all the LEAD Annotation objects in an AnnContainer into one or more DICOM annotation objects, and stores the result in a Leadtools.Dicom.DicomDataSet.

Syntax
C#
C++
public DicomElement FromAnnContainerToDataSet( 
   DicomDataSet ds, 
   AnnContainer annContainer 
) 
vb[VB Syntax] 
  
Public Overloads Function FromAnnContainerToDataSet( _ 
   ByVal _ds_ As DicomDataSet, _ 
   ByVal _annContainer_ As AnnContainer _ 
) As DicomElement 
public: 
DicomElement^ FromAnnContainerToDataSet(  
   DicomDataSet^ ds, 
   AnnContainer^ annContainer 
)  

Parameters

ds
The Leadtools.Dicom.DicomDataSet where the resulting DICOM Annotation objects are stored.

annContainer
The Leadtools.Annotations.Engine.AnnContainer that contains a list of Leadtools.Annotations.Engine.AnnObject objects that are to be converted.

Return Value

A Leadtools.Dicom.DicomElement that represents GraphicAnnotationSequence item that contains the DICOM Annotations.

Remarks

This function converts a LEAD Leadtools.Annotations.Engine.AnnContainer of Leadtools.Annotations.Engine.AnnObject objects into one or more DICOM annotation objects (text, graphic, and compound graphic), and stores the result in a new Graphic Annotation Sequence Item Element inside the ds parameter.

If any of the resulting DICOM annotation object is a "Compound Graphic " then it will be added under the "Compound Graphic Sequence" 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".

If the resulting DICOM annotation object is a "Graphic Object" then it will be added under the "Graphic Object Sequence".

Note: when converting a Leadtools.Annotations.Engine.AnnPolyRulerObject, Leadtools.Annotations.Engine.AnnProtractorObject, or Leadtools.Annotations.Engine.AnnCrossProductObject, the result will be one or more 'grouped' Leadtools.Dicom.DicomAnnotationObject objects which have the same Leadtools.Dicom.DicomAnnotationObject.GraphicGroupId. In this case, a corresponding Graphic Group Sequence item (0070,0234) will be inserted into the ds.

Example

This example does the following:

  1. Creates a Leadtools.Annotations.Engine.AnnRectangleObject, a Leadtools.Annotations.Engine.AnnPolylineObject, and a Leadtools.Annotations.Engine.AnnPolyRulerObject.
  2. Creates an Leadtools.Annotations.Engine.AnnContainer and adds the three objects
  3. Creates a converter
  4. Converts the Leadtools.Annotations.Engine.AnnContainer to DICOM Annotations, and stores the result in a file that contains a Grayscale Softcopy Presentation
