      • atPosition

        public static javafx.geometry.Point2D atPosition​(javafx.geometry.Bounds bounds,
                                                 javafx.geometry.Pos position)
        Parameters:
        bounds - the given bounds
        position - the position within the bounds
        Returns:
        a point somewhere in the given bounds whose x and y values are determined by passing the given position to computePositionFactors(Pos).

      • atPositionFactors

        public static javafx.geometry.Point2D atPositionFactors​(javafx.geometry.Bounds bounds,
                                                        javafx.geometry.Point2D positionFactors)
        Returns the point within the given bounds computed using the given positionFactors.

        The x-component of the returned point is computed using:

        x = bounds.x + positionFactors.x * bounds.width

        and analogously the y-component of the returned point is computed using: y = bounds.y + positionFactors.y * bounds.height

        Parameters:
        bounds - the given bounds
        positionFactors - a Point2D object whose x and y values represent percentages (0.0 = 0% and 1.0 = 100%). As an example, an x value of 0 will return Bounds.getMinX(), 1.0 will return Bounds.getMaxX(), and 0.5 will return bounds.getMinX() + (bounds.getWidth() * positionFactors.getX().
        Returns:
        the point somewhere within the given bounds whose x and y values are determined by the given positionFactors.

      • computePositionFactors

        public static javafx.geometry.Point2D computePositionFactors​(javafx.geometry.Pos position)
        Computes the width/height factors for the point defined by the given position.

        The width factor is returned in the x component and the height factor in the y component of the point. That is, Pos.TOP_LEFT has a width and height factor of 0.0, whereas Pos.BOTTOM_RIGHT has a width and height factor of 1.0.

        Parameters:
        position - the position to compute width/height factors for
        Returns:
        a Point2D that can be used as a positionFactor object in atPositionFactors(Bounds, Point2D).
