DefaultObject Property

Gets or sets the defaults used when calling ToAnnObject.

Syntax

C#
Visual Basic
Objective-C
Java
C++

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

Example

This sample does the following:

Creates a rectangle annotation object.
Creates Leadtools.Dicom.DicomDataSet that is type GrayscaleSoftcopyPresentationState that will hold the annotations.
Creates a converter
Converts LEAD annotation to DICOM annotations, and automatically saves in the Leadtools.Dicom.DicomDataSet
