Property descriptions
iOSPath.CurrentPoint
CurrentPoint As Point
The current point.
This property is read-only.
iOSPath.IsEmpty
IsEmpty As Boolean
Checks if the path is empty. An empty path contains no elements.
This property is read-only.
iOSPath.IsRectangle
IsRectangle As Boolean
Checks if the path is a rectangle.
This property is read-only.
Method descriptions
iOSPath.AddArc
AddArc(x As Double, y As Double, radius As Double, startAngle As Double, endAngle As Double, clockwise As Boolean)
Adds an arc to the path.
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.
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)
iOSPath.AddCurveToPoint
AddCurveToPoint(cp1x As Double, cp1y As Double, cp2X As Double, cp2Y As Double, x As Double, y As Double)
Adds a cubic Bézier curve to the point in the path.
Draw a cloud:
Var curve As New iOSPath
curve.MoveToPoint(20, 20)
curve.AddCurveToPoint(20, 100, 200, 100, 200, 20)
g.DrawPath(curve)
' Draw a fluffy white cloud
Var cloud As New iOSPath
cloud.MoveToPoint(170, 80)
cloud.AddCurveToPoint(130, 100, 130, 150, 230, 150)
cloud.AddCurveToPoint(250, 180, 320, 180, 340, 150)
cloud.AddCurveToPoint(420, 150, 420, 120, 390, 100)
cloud.AddCurveToPoint(430, 40, 370, 30, 340, 50)
cloud.AddCurveToPoint(320, 5, 250, 20, 250, 50)
cloud.AddCurveToPoint(200, 5, 150, 20, 170, 80)
g.LineColor = Color.Blue
g.LineWidth = 5
g.DrawPath(cloud)
iOSPath.AddQuadraticCurveToPoint
AddQuadraticCurveToPoint(cpX As Double, cpY As Double, x As Double, y As Double)
Adds a quadratic Bézier curve to the point in the path.
Draw a curve:
Var qCurve As New iOSPath
qCurve.MoveToPoint(38, 150)
qCurve.AddQuadraticCurveToPoint(138, 0, 238, 150)
g.LineWidth = 10
g.DrawPath(qCurve)
iOSPath.AddRect
AddRect(x As Double, y As Double, width As Double, height As Double)
Adds a rectangle to the path.
A simple rectangle:
Var rect As New iOSPath
rect.AddRect(10, 10, 100, 150)
g.DrawPath(rect)
iOSPath.AddRoundRect
AddRoundRect(x As Double, y As Double, width As Double, height As Double, cornerWidth As Double, cornerHeight As Double)
Adds a rounded rectangle to the path.
A simple rounded rectangle:
Var rect As New iOSPath
rect.AddRoundRect(10, 10, 100, 150, 10, 10)
g.DrawPath(rect)
iOSPath.LineToPoint
LineToPoint(x As Double, y As Double)
Draws a line from the CurrentPoint to the specified point.
Draw a triangle:
Var p As New iOSPath
p.MoveToPoint(0, 0) ' Start location
p.LineToPoint(20, 44)
p.LineToPoint(40, 0)
p.LineToPoint(0, 0)
g.LineColor = Color.Blue
g.DrawPath(p)
iOSPath.MoveToPoint
MoveToPoint(x As Double, y As Double)
Moves to the point without drawing anything.
Var p As New iOSPath
p.MoveToPoint(50, 50)
