Syntax

public static double PointToLine(
	int Px,
	int Py,
	int[] devA,
	int[] devB
)

Public Shared Function PointToLine ( 
	Px As Integer,
	Py As Integer,
	devA As Integer(),
	devB As Integer()
) As Double

public:
static double PointToLine(
	int Px, 
	int Py, 
	array<int>^ devA, 
	array<int>^ devB
)

static member PointToLine : 
        Px : int * 
        Py : int * 
        devA : int[] * 
        devB : int[] -> float

Px: Type: SystemInt32
An int which specifies the x coordinate of the point (Px,Py).
Py: Type: SystemInt32
An int which specifies the y coordinate of the point (Px,Py).
devA: Type: SystemInt32
An int[] which specifies the point that defines the head of the line segment.
devB: Type: SystemInt32
An int[] which specifies the point that defines the tail of the line segment.

Type: Double
A double which contains the distance from the point (Px,Py) to the line segment AB.

Remarks

If the closest point from P to the line AB is not between A and B then the distance to the closer of A and B is returned.
