Syntax

Objective-C

C++/CLI

Java

Python

public int MarkDetectedCount { get; set; }

@property (nonatomic, assign) NSUInteger markDetectedCount;

public int getMarkDetectedCount(); 
public void setMarkDetectedCount( 
   int intValue 
);

public: 
property int MarkDetectedCount { 
   int get(); 
   void set (    int ); 
}

MarkDetectedCount # get and set (SearchRegistrationMarksCommandData)

Property Value

The number of detected registration marks inside the search area.

Remarks

This property will be updated by the SearchRegistrationMarksCommand. This property indicates how many elements of the MarkDetectedPoints array will be filled. For more information, refer to Detecting Registration Marks.
