LineProfileCommand Constructor(LeadPoint,LeadPoint)

Summary

Initializes a new LineProfileCommand class object with explicit parameters. The RedBuffer, GreenBuffer and BlueBuffer properties are updated with the corresponding color information about the pixels between the points specified in the firstPoint and secondPoint parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public LineProfileCommand( 
   LeadPoint firstPoint, 
   LeadPoint secondPoint 
)

- (instancetype)initWithFirstPoint:(LeadPoint)firstPoint secondPoint:(LeadPoint)secondPoint NS_DESIGNATED_INITIALIZER;

public LineProfileCommand( 
   LeadPoint firstPoint, 
   LeadPoint secondPoint 
);

public: 
LineProfileCommand(  
   LeadPoint firstPoint, 
   LeadPoint secondPoint 
)

__init__(self,firstPoint,secondPoint) # Overloaded constructor

Parameters

firstPoint
The starting point for the line.

secondPoint
The end point for the line.

Example

Run the LineProfileCommand on an image.

Java

   // Prepare the command 
   LineProfileCommand command = new LineProfileCommand(new LeadPoint(0, 0), new LeadPoint(50, 50));
