Constructs a Line from a point and an angle (in degrees).

Namespace:  AForge.Math.Geometry
Assembly:  AForge.Math (in AForge.Math.dll) Version: 2.2.5.0 (2.2.5.0)

Syntax

C#
public static Line FromPointTheta(
	Point point,
	float theta
)

Parameters

point
Type: AForge..::.Point
The minimum distance from the line to the origin.
theta
Type: System..::.Single
The angle of the normal vector from the origin to the line.

Return Value

Returns a Line representing the specified line.

Remarks

theta is the counterclockwise rotation from the positive X axis to the vector through the origin and normal to the line.

This means that if theta is in [0,180), the point on the line closest to the origin is on the positive X or Y axes, or in quadrants I or II. Likewise, if theta is in [180,360), the point on the line closest to the origin is on the negative X or Y axes, or in quadrants III or IV.
