• x: Number - The X component of the point.
• y: Number - The Y component of the point.

• point: Point2D - the other point

• other: Point2D or Object - An object to compare this object to.

• direction: Vector2D or Number or Array [ Number ] - A direction of movement defined by a Vector2D, an Array with 2 values (X and Y), or a number representing the X offset.
• y: Number - The Y offset to move in, when only the X offset is specified as the first argument. | Optional

3 Examples:

// Move the point by given a Vector2D object
var vec = new Vector2D(-1, -1);
point.move(vec);

// Move the point by given a 2-element array
var arr = [-1, -1];
point.move(arr);

// Move the point by given x, y offsets
var xoffset = -1,
    yoffset = -1;
point.move(xoffset, yoffset);

• angle: Number - The angle of rotation in radians
• origin: Point2D or Number or Array [ Number ] - An optional origin of rotation defined by a Point2D, an Array with 2 values (X and Y), or a number representing the X value. | Optional
• y: Number - The Y position to rotate around, when only the X offset is specified in the previous argument. | Optional

3 Examples:

// Rotate the point by given angle around the default 0,0 point as origin
point.rotate(Math.PI/2);

// Rotate the point by given angle and the origin specified in a 2-element array
point.rotate(Math.PI/2, [1, 1]);

// Rotate the point by given angle and the origin specified in the 2nd and 3rd arguments
point.rotate(Math.PI/2, 1, 1);

• scale: Vector2D or Array [ Number ] or Number - A scale defined by a Vector2D, an Array with 2 values (X and Y), or a number representing the X scale (and Y scale if no additional parameter is specified.)
• y: Number - An option Y scale to use if an X scale was specified as the first argument. If this argument is not specified then uniform scaling is assumed. | Optional

4 Examples:

// Scale the point by given one scale number uniformly
point.scale(0.5);

// Scale the point by given X and Y scale numbers
point.scale(0.5, 0.75);

// Scale the point by given a Vector2D object
var vec = new Vector2D(0.5, 0.75);
point.scale(vec);

// Scale the point by given a 2-element array with X and Y scale numbers
point.scale([0.5, 0.75]);

• matrix: Matrix2D or Array [ Number ] - A Matrix or an Array of 9 numbers.

2 Examples:

// Transform the point (x, y) by given a 9-element array 
tm = [a, b, 0, c, d, 0, e, f, 1] representing following matrix
[a b 0] 
[c d 0]
[e f 1]  
new coordinates would be (a*x + c*y + e, b*x + d*y + f)

point.transform(tm);

// Transform the point by given a Matrix2D object
point.transform(tm);
