Constructors

PolarPoint(Double, Double)

Initializes polar coordinates

Declaration
public PolarPoint(double r, double theta)
Parameters
Type Name Description
System.Double r
System.Double theta

PolarPoint(Point, Point)

Initializes polar coordinates from 2-d cartesian coordinates

Declaration
public PolarPoint(Point center, Point point)
Parameters
Type Name Description
System.Drawing.Point center
System.Drawing.Point point

PolarPoint(Int32, Int32, Int32, Int32)

Initializes polar coordinates from 2-d cartesian coordinates of 'x1, y1, x2, y2' format

Declaration
public PolarPoint(int x1, int y1, int x2, int y2)
Parameters
Type Name Description
System.Int32 x1
System.Int32 y1
System.Int32 x2
System.Int32 y2

Properties

Point

Returns polar coordinate converted to 2-d cartesian coordinates. Coordinates are relative to 0,0 of the angle base vertex

Declaration
public Point Point { get; }
Property Value
Type Description
System.Drawing.Point

R

R coordinate component which is coordinate distance from point of coordinates origin

Declaration
public double R { get; set; }
Property Value
Type Description
System.Double

Theta

Angular azimuth coordinate component. An angle must be between 0 and 2Pi. Note: Due to screen Y coordinate going from top to bottom (in usual orientation) Theta angle may be reversed, that is - be positive in the lower half coordinate plane. Please refer to: http://en.wikipedia.org/wiki/Polar_coordinates

Declaration
public double Theta { get; set; }
Property Value
Type Description
System.Double
