The Point object represents a location in a twodimensional coordinate system, where x represents the horizontal axis and y represents the vertical axis.
The following code creates a point at(0,0):
Methods and properties of the following classes use Point objects:
 BitmapData
 DisplayObject
 DisplayObjectContainer
 DisplacementMapFilter
 NativeWindow
 Matrix
 Rectangle
You can use the new Point()
constructor to create a Point
object.

Static methods
staticdistance(pt1:Point, pt2:Point):Float
Returns the distance between pt1
and pt2
.
Parameters:
pt1  The first point. 

pt2  The second point. 
Returns:
The distance between the first and second points.
staticinterpolate(pt1:Point, pt2:Point, f:Float):Point
Determines a point between two specified points. The parameter
f
determines where the new interpolated point is located
relative to the two end points specified by parameters pt1
and pt2
. The closer the value of the parameter f
is to 1.0
, the closer the interpolated point is to the first
point(parameter pt1
). The closer the value of the parameter
f
is to 0, the closer the interpolated point is to the second
point(parameter pt2
).
Parameters:
pt1  The first point. 

pt2  The second point. 
f  The level of interpolation between the two points. Indicates
where the new point will be, along the line between

Returns:
The new, interpolated point.
staticinterpolateToOutput(pt1:Point, pt2:Point, f:Float, output:Point):Point
Determines a point between two specified points, and sets them on the
specified output point (or a new point, if null). The parameter
f
determines where the new interpolated point is located
relative to the two end points specified by parameters pt1
and pt2
. The closer the value of the parameter f
is to 1.0
, the closer the interpolated point is to the first
point(parameter pt1
). The closer the value of the parameter
f
is to 0, the closer the interpolated point is to the second
point(parameter pt2
).
Parameters:
pt1  The first point. 

pt2  The second point. 
f  The level of interpolation between the two points. Indicates
where the new point will be, along the line between

output  An optional point to be used for the result of the operation. 
Returns:
The new, interpolated point (or the object passed in as the output parameter, if not null).
staticpolar(len:Float, angle:Float):Point
Converts a pair of polar coordinates to a Cartesian point coordinate.
Parameters:
len  The length coordinate of the polar pair. 

angle  The angle, in radians, of the polar pair. 
Returns:
The Cartesian point.
staticpolarToOutput(len:Float, angle:Float, output:Point):Point
Converts a pair of polar coordinates to a Cartesian point coordinate, and sets them on the specified output point (or a new point, if null).
Parameters:
len  The length coordinate of the polar pair. 

angle  The angle, in radians, of the polar pair. 
output  An optional point to be used for the result of the operation. 
Returns:
The Cartesian point (or the object passed in as the output parameter, if not null).
Constructor
new(x:Float = 0, y:Float = 0)
Creates a new point. If you pass no parameters to this method, a point is created at(0,0).
Parameters:
x  The horizontal coordinate. 

y  The vertical coordinate. 
Variables
Methods
add(v:Point):Point
Adds the coordinates of another point to the coordinates of this point to create a new point.
Parameters:
v  The point to be added. 

Returns:
The new point.
addToOutput(v:Point, output:Point):Point
Adds the coordinates of another point to the coordinates of this point and sets them on the specified output point (or a new point, if null).
Parameters:
v  The point to be added. 

output  An optional point to be used for the result of the operation. 
Returns:
The new point (or the object passed in as the output parameter, if not null).
copyFrom(sourcePoint:Point):Void
Copies all of the point data from the source Point object into the calling Point object.
Parameters:
sourcePoint  The Point object from which to copy the data. 

equals(toCompare:Point):Bool
Determines whether two points are equal. Two points are equal if they have the same x and y values.
Parameters:
toCompare  The point to be compared. 

Returns:
A value of true
if the object is equal to this Point
object; false
if it is not equal.
normalize(thickness:Float):Void
Scales the line segment between(0,0) and the current point to a set length.
Parameters:
thickness  The scaling value. For example, if the current point is (0,5), and you normalize it to 1, the point returned is at(0,1). 

Returns:
The normalized point.
offset(dx:Float, dy:Float):Void
Offsets the Point object by the specified amount. The value of
dx
is added to the original value of x to create the
new x value. The value of dy
is added to the original
value of y to create the new y value.
Parameters:
dx  The amount by which to offset the horizontal coordinate, x. 

dy  The amount by which to offset the vertical coordinate, y. 
setTo(xa:Float, ya:Float):Void
Sets the members of Point to the specified values
Parameters:
xa  the values to set the point to. 

null  ya 
subtract(v:Point):Point
Subtracts the coordinates of another point from the coordinates of this point to create a new point.
Parameters:
v  The point to be subtracted. 

Returns:
The new point.
subtractToOutput(v:Point, output:Point):Point
Subtracts the coordinates of another point from the coordinates of this point, and sets them on the specified output point (or a new point, if null).
Parameters:
v  The point to be subtracted. 

output  An optional point to be used for the result of the operation. 
Returns:
The new point (or the object passed in as the output parameter, if not null).
toString():String
Returns a string that contains the values of the x and y
coordinates. The string has the form "(x=_x_,
y=_y_)"
, so calling the toString()
method for a
point at 23,17 would return "(x=23, y=17)"
.
Returns:
The string representation of the coordinates.
