IncrementCompoundGraphicInstanceId Method

Summary
Increments the CompoundGraphicInstanceId to a new,unused value that can be assigned to the next DICOM Compound Graphic.
Syntax
C#
C++/CLI
public int IncrementCompoundGraphicInstanceId() 
public: 
int IncrementCompoundGraphicInstanceId();  

Return Value

The new value for CompoundGraphicInstanceId.

Remarks

When a LEAD Leadtools.Annotations.Engine.AnnObject is converted to a Leadtools.Dicom.DicomCompoundGraphic, it will be assigned a unique CompoundGraphicInstanceId. The DicomAnnotationsUtilities class maintains a CompoundGraphicInstanceId that is used for each DICOM Compound Graphic. Once a CompoundGraphicInstanceId is assigned to a DICOM Compound Graphic, it must no longer be used. The IncrementCompoundGraphicInstanceId function is used to increment to the next unused value. The default behavior of this function is to add one to the previous CompoundGraphicInstanceId, but this behavior can be changed by subscribing to the OnIncrementCompoundGraphicInstanceId event, and changing the value of CompoundGraphicInstanceId.
