Rect

declare class Rect {}

Rect holds four integer coordinates for a rectangle. The rectangle is represented by the coordinates of its 4 edges (left, top, right bottom). These fields can be accessed directly. Use width() and height() to retrieve the rectangle's width and height. Note: most methods do not check to see that the coordinates are sorted correctly (i.e. left <= right and top <= bottom).

Note that the right and bottom coordinates are exclusive. This means a Rect being drawn untransformed onto a Canvas will draw into the column and row described by its left and top coordinates, but not those of its bottom and right.

Instance Method​

isEmpty​

declare class Rect {
    isEmpty() : boolean
}

  • Description​

    Returns true if the rectangle is empty (left >= right or top >= bottom).

equals​

declare class Rect {
    equals(rect: Rect): boolean
}

  • Description​

    Indicates whether some other object is "equal to" this one.

height​

declare class Rect {
    height(): number
}

  • Description​

    Returns Rect height

width​

declare class Rect {
    width(): number
}

  • Description​

    Returns rect width

centerX​

declare class Rect {
    centerX(): number
}

  • Description​

    the horizontal center of the rectangle. If the computed value is fractional, this method returns the largest integer that is less than the computed value.

centerY​

declare class Rect {
    centerY(): number
}

  • Description​

    the vertical center of the rectangle. If the computed value is fractional, this method returns the largest integer that is less than the computed value.

exactCenterX​

declare class Rect {
    exactCenterX(): number
}

  • Description​

    the exact horizontal center of the rectangle as a float.

exactCenterY​

declare class Rect {
    exactCenterY(): number
}

  • Description​

    the exact vertical center of the rectangle as a float.

offset​

declare class Rect {
    offset(dx: number, dy: number): void
}

  • Description​

    Offset the rectangle by adding dx to its left and right coordinates, and adding dy to its top and bottom coordinates.

offsetTo​

declare class Rect {
    offsetTo(newLeft: number, newTop: number): void
}

  • Description​

    Offset the rectangle to a specific (left, top) position, keeping its width and height the same.

setEmpty​

declare class Rect {
    setEmpty(): void
}

  • Description​

    Set the rectangle to (0,0,0,0)

inset​

declare class Rect {
    inset(dx: number, dy: number): void
}

  • Description​

    Insets the rectangle on all sides specified by the insets.

contains​

declare class Rect {
    contains(rect: Rect): boolean
}

  • Description​

    Returns true iff the specified rectangle r is inside or equal to this rectangle.

contains​

declare class Rect {
    contains(x: number, y: number): boolean
}

  • Description​

    Returns true if (x,y) is inside the rectangle.

contains​

declare class Rect {
    contains(left: number, top: number, right: number, bottom: number)
}

  • Description​

    Returns true iff the 4 specified sides of a rectangle are inside or equal to this rectangle.
