Method

iOSPath.AddArc(x As Double, y As Double, radius As Double, startAngle As Double, endAngle As Double, clockwise As Boolean)

Supported on Mobile(iOS).

Adds an arc to the path.

Parameters

Value	Description
x	The x-coordinate of the center point of the arc.
y	The y-coordinate of the center point of the arc.
radius	The radius of the arc.
startAngle	The angle (in radians) that determines the starting point of the arc, measured from the x-axis.
endAngle	The angle (in radians) that determines the ending point of the arc, measured from the x-axis.
clockwise	A Boolean value that specifies whether or not to draw the arc in the clockwise direction.

Notes

The ending point of the Arc becomes the start point for the next element added to the path. In particular, if you add two arcs in a row, there will be a line that connects the ending point of the first arc to the starting point of the second arc. If you do not want this behavior, set the new starting point manually using MoveToPoint.

Sample Code

Draw an arc that is 1/4 of a circle:

Const Pi = 3.14159
Var arc As New iOSPath
arc.AddArc(50, 50, 20, 0, Pi / 2, False)
g.DrawPath(arc)
