Class Point
A Point represents an x and ycoordinate pair in twodimensional space.
Use the static functions Point.parse and Point.stringify to convert to and from a standard string representation that is independent of the current locale.
When an instance of this class is the value of a property of a GraphObject class or Diagram or CommandHandler or a Tool class, you should treat the object as if it were frozen or readonly  you cannot modify its properties. This allows the property to return a value without allocating a new instance. If you need to do your own calculations with the value, call copy to make a new instance with the same values that you can modify.
Many methods modify the object's properties and then return a reference to "this" object. The only instance method to allocate a new object is the copy method. The static Point.parse method also allocates a new object.
The "Debug" implementation of this class is significantly slower than the "Release" implementation, mostly due to additional error checking.
You cannot inherit from this class.
Constructor Summary Details
Name  Description 

Point(x, y)

The default constructor produces the Point(0,0).More... This constructor may take either zero arguments or two arguments.

Properties Summary Details
Name, Value Type  Description 

x
{number}

Gets or sets the x value of the Point. 
y
{number}

Gets or sets the y value of the Point. 
Method Summary Details
Name, Return Type  Description 

add(p)
{Point}


copy()
{Point}

Create a copy of this Point, with the same values.

direction(px, py)
{number}

Compute the angle from this Point to a given (px,py) point.More... However, if the point is the same as this Point, the direction is zero. See also:

<static>
Point.direction(px, py, qx, qy)
{number}

This static function returns the angle in degrees of the line from point P to point Q.More...

directionPoint(p)
{number}

Compute the angle from this Point to a given Point.More... However, if the given Point is the same as this Point, the direction is zero. See also:

<static>
Point.distanceLineSegmentSquared(px, py, ax, ay, bx, by)
{number}

This static function returns the square of the distance from the point P to the finite line segment from point A to point B.More...

distanceSquared(px, py)
{number}

Returns the square of the distance from this point to a given point (px, py).More... See also:

<static>
Point.distanceSquared(px, py, qx, qy)
{number}

This static function returns the square of the distance from the point P to the point Q.More...

distanceSquaredPoint(p)
{number}


equals(p)
{boolean}


equalTo(x, y)
{boolean}


isReal()
{boolean}

True if this Point has X and Y values that are real numbers and not infinity.

normalize()
{Point}


offset(dx, dy)
{Point}


<static>
Point.parse(str)
{Point}

This static function can be used to read in a Point from a string that was produced by Point.stringify.More...

projectOntoLineSegment(px, py, qx, qy)
{Point}
1.3

Modify this point to be the closest point to this point that is on a finite line segment.More...

projectOntoLineSegmentPoint(p, q)
{Point}
1.3


rotate(angle)
{Point}


scale(sx, sy)
{Point}


set(p)
{Point}


setRectSpot(r, spot)
{Point}

Modify this Point so that its X and Y values correspond to a particular Spot in a given Rect.More... The result is meaningless if Spot.isNoSpot is true for the given Spot. See also:

setSpot(x, y, w, h, spot)
{Point}

Modify this Point so that its X and Y values correspond to a particular Spot in a given rectangle.More... The result is meaningless if Spot.isNoSpot is true for the given Spot. See also:

setTo(x, y)
{Point}


snapToGrid(originx, originy, cellwidth, cellheight)
{Point}
1.3

Modify this point to be at the nearest point on an infinite grid, given the grid's origin and size of each grid cell.More...

snapToGridPoint(origin, cellsize)
{Point}
1.3


<static>
Point.stringify(val)
{string}

This static function can be used to write out a Point as a string that can be read by Point.parse.More...

subtract(p)
{Point}
