RemoveBackground Property

Summary

Gets or sets a value that indicates whether to remove the background of the images that appear on the MPR planes or render only the data.

Syntax

C++

public bool RemoveBackground {get; set;}

Public Property RemoveBackground As Boolean

public: 
property bool RemoveBackground { 
   bool get(); 
   void set (    bool ); 
}

Property Value

true to remove the background; otherwise, false.

Remarks

RemoveBackground works by detecting the least important area of the 3D object and removing it for better visualization.
