Class ArcLineSegment

Represents a line segment that contains radii and angles that will be rendered as a elliptical arc.

Syntax

public class ArcLineSegment : object, ILineSegment

Constructors

ArcLineSegment(PointF, PointF, SizeF, Single, Boolean, Boolean)

Initializes a new instance of the ArcLineSegment class.

Declaration

public ArcLineSegment(PointF from, PointF to, SizeF radius, float rotation, bool largeArc, bool sweep)

Parameters

Type	Name	Description
PointF	from	The absolute coordinates of the current point on the path.
PointF	to	The absolute coordinates of the final point of the arc.
SizeF	radius	The radii of the ellipse (also known as its semi-major and semi-minor axes).
Single	rotation	The angle, in degrees, from the x-axis of the current coordinate system to the x-axis of the ellipse.
Boolean	largeArc	The large arc flag, and is false if an arc spanning less than or equal to 180 degrees is chosen, or true if an arc spanning greater than 180 degrees is chosen.
Boolean	sweep	The sweep flag, and is false if the line joining center to arc sweeps through decreasing angles, or true if it sweeps through increasing angles.

ArcLineSegment(PointF, SizeF, Single, Single, Single)

Initializes a new instance of the ArcLineSegment class.

Declaration

public ArcLineSegment(PointF center, SizeF radius, float rotation, float startAngle, float sweepAngle)

Parameters

Type	Name	Description
PointF	center	The coordinates of the center of the ellipse.
SizeF	radius	The radii of the ellipse (also known as its semi-major and semi-minor axes).
Single	rotation	The angle, in degrees, from the x-axis of the current coordinate system to the x-axis of the ellipse.
Single	startAngle	The start angle of the elliptical arc prior to the stretch and rotate operations. (0 is at the 3 o'clock position of the arc's circle).
Single	sweepAngle	The angle between startAngle and the end of the arc.
