Syntax
C#
VB
Java
Objective-C
C++
Public Function New( _ 
   ByVal firstPoint As LeadPoint, _ 
   ByVal secondPoint As LeadPoint _ 
) 
- (instancetype)initWithFirstPoint:(LeadPoint)firstPoint 
                       secondPoint:(LeadPoint)secondPoint 
public LineProfileCommand( 
   LeadPoint firstPoint,  
   LeadPoint secondPoint 
) 
public: 
LineProfileCommand(  
   LeadPoint firstPoint, 
   LeadPoint secondPoint 
) 

Parameters

firstPoint
The starting point for the line.

secondPoint
The end point for the line.

Example

Run the LineProfileCommand on an image.
