Example 





Leadtools.Dicom.Annotations Namespace > DicomAnnotationsUtilities Class : DefaultObject Property
Gets or sets the defaults used when calling ToAnnObject.
Syntax
public object DefaultObject {get; set;}
'Declaration
 
Public Property DefaultObject As Object
'Usage
 
Dim instance As DicomAnnotationsUtilities
Dim value As Object
 
instance.DefaultObject = value
 
value = instance.DefaultObject

            

        

            

            

            

        

            

            
public:
property Object^ DefaultObject {
   Object^ get();
   void set (    Object^ value);
}

            

        

            

        
            
            
            
Property Value
Contains defaults that are used when when calling ToAnnObject.

            
            
            
            
Remarks
A Leadtools.Dicom.DicomAnnotationObject can be filled, however it doesn't have fill color, pen color, text color or a font. An Leadtools.Annotations.AnnObject can have a fill color, a pen color, a text color, and a font. When calling ToAnnObject to convert a Leadtools.Dicom.DicomAnnotationObject, the DefaultObject is an AnnObject that is referenced when setting the default values.

Note: for Silverlight users, the System.Object is of type Leadtools.Windows.Annotations.AnnObject
