MappingPoints Property

Summary

Gets or sets an array of LeadPoint structures that contains the mapped points in the output image.

Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint[] MappingPoints { get; set; }

@property (nonatomic, strong, nullable) NSArray<NSValue *> *mappingPoints; //LeadPoint

public LeadPoint[ getMappingPoints(); 
public void setMappingPoints( 
   LeadPoint[] leadPoint[ 
);

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

MappingPoints # get and set (ManualPerspectiveDeskewCommand)

Property Value

Array of points that map each point in the InputPoints list to its output location.
