ToAnnObject(IDicomAnnotationObject) Method

Summary

Converts an object implementing the Leadtools.IDicomAnnotationObject interface to an AnnObject.

Syntax

C++/CLI

public AnnObject ToAnnObject(  
   IDicomAnnotationObject dicomAnnotationObject 
)

public: 
AnnObject^ ToAnnObject(  
   IDicomAnnotationObject^ dicomAnnotationObject 
)

Parameters

dicomAnnotationObject
The DICOM annotation object that is being converted

Return Value

An AnnObject representation of the DICOM annotation if successful; null if the Leadtools.Dicom.DicomAnnotationObject cannot be converted.

Remarks

Note that if the Leadtools.IDicomAnnotationObject is a Leadtools.Dicom.DicomCompoundGraphic, and the objects are 'grouped', then the conversion might not return the original Leadtools.Annotations.Engine.AnnObject. For example, if the original Leadtools.Annotations.Engine.AnnObject is a Leadtools.Annotations.Engine.AnnPolyRulerObject, it will be converted to two Leadtools.Dicom.DicomCompoundGraphic rulers, with the same Leadtools.Dicom.DicomCompoundGraphic.GraphicGroupId. Using this method to convert back to an Leadtools.Annotations.Engine.AnnObject, the method will be called twice two return two rulers. So in this case, it is better to use Leadtools.Annotations.Engine.AnnObject, as this will convert to the original Leadtools.Annotations.Engine.AnnPolyRulerObject.

Example

This example does the following:

Creates a rectangle Leadtools.Dicom.DicomCompoundGraphic
Creates a converter
Converts the Leadtools.Dicom.DicomCompoundGraphic to a LEAD Leadtools.Annotations.Engine.AnnObject
