Field Detail

angle

Arc end angle.

arcTo

is a relative or absolute arc ?

Defined clockwise or counterclockwise ?

newPosition

spare point for calculations

points

A collection of CAAT.Math.Point objects which defines the arc (center, start, end)

radius

Arc radius.

startAngle

Arc start angle.

Method Detail

<private> __init()

applyAsPath(director)

Parameters:
director

endCurvePosition()

An arc starts and ends in the same point.

{number} finalPositionX()

Returns final path segment point's x coordinate.

Returns:: {number}

getContour(iSize)

iSize

getControlPoint(index)

Parameters:
index

getPosition(time)

Parameters:
time

getPositionFromLength(iLength)

Parameters:
iLength

initialize(x, y, r, angle)

Parameters:

y
r
angle

{number} initialPositionX()

Returns initial path segment point's x coordinate.

Returns:: {number}

isArcTo()

isClockWise()

{number} numControlPoints()

Get the number of control points. For this type of path segment, start and ending path segment points. Defaults to 2.

Returns:: {number}

paint(director, bDrawHandles)

Draws this path segment on screen. Optionally it can draw handles for every control point, in this case, start and ending path segment points.

Parameters:
finalX: {number}
finalY: {number}

setInitialPosition(x, y)

Set this path segment's starting position. This method should not be called again after setFinalPosition has been called.

Parameters:
x: {number}
y: {number}

setPoint(point, index)

point
index

setPoints(points)

An array of {CAAT.Point} composed of two points.

Parameters:
points: {Array}

setRadius(r)

Parameters:
r
