MarkDetectedPoints Property

Summary

Gets or sets an array which will be filled with the location points of the detected registration marks.

Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint[] MarkDetectedPoints { get; set; }

@property (nonatomic, strong) NSMutableArray<NSValue *> *markDetectedPoints; //LeadPoint

public LeadPoint[ getMarkDetectedPoints(); 
public void setMarkDetectedPoints( 
   LeadPoint[] leadPoint[ 
);

public: 
property array<LeadPoint>^ MarkDetectedPoints { 
   array<LeadPoint>^ get(); 
   void set (    array<LeadPoint>^ ); 
}

MarkDetectedPoints # get and set (SearchRegistrationMarksCommandData)

Property Value

Array which will be filled with the location points of the detected registration marks. SearchRegistrationMarksCommand will fill the first MarkDetectedCount elements in this array.
