public virtual int CaptureStillDelay { get; set; } 
Public Overridable Property CaptureStillDelay As Integer 
virtual property int CaptureStillDelay { 
   int get(); 
   void set (    int ); 

Property Value

A value representing the capture time delay in milliseconds.


Call the CaptureDIB or CaptureImage methods to capture a still image using this capture time delay after the capture graph is started.
