CreateCompoundGraphic Method

Summary

Creates a new compound graphic annotation.

Syntax
C#
VB
C++
public void CreateCompoundGraphic( 
   DicomElement graphicAnnSQItem, 
   DicomCompoundGraphic compoundGraphic, 
   bool checkLayer 
) 
Public Sub CreateCompoundGraphic( _ 
   ByVal graphicAnnSQItem As DicomElement, _ 
   ByVal compoundGraphic As DicomCompoundGraphic, _ 
   ByVal checkLayer As Boolean _ 
)  
public: 
void CreateCompoundGraphic(  
   DicomElement^ graphicAnnSQItem, 
   DicomCompoundGraphic^ compoundGraphic, 
   bool checkLayer 
)  

Parameters

graphicAnnSQItem
An item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".

compoundGraphic
Compound Graphic attributes

checkLayer
true to verify the existence of the layer to which the new object will be added (the method will fail if the layer does not exist); false to add the new object without verifying the existence of the layer.

Remarks

When checkLayer is set to true, the method checks if the layer specified in graphicObject exists. If it does not exist, the method will throw an exception.

Example

This example will create two compound graphic objects (ruler, rectangle), add them to a presentation state, and then perform tests on the presentation state.
