      Returns true if the bounds contain the specified point within the given tolerance.
      Parameters:
      r - the bounds
      p - the point
      tolerance - the tolerance
      Returns:
      true if inside

    • contains

      Returns true if the bounds contain the specified point within the given tolerance.
      Parameters:

    • getBounds

      public static javafx.geometry.Bounds getBounds(javafx.geometry.Rectangle2D r)
      Gets the bounds of the specified shape.
      Parameters:
      r - a rectangle
      Returns:
      JavaFX bounds

    • grow

      public static javafx.geometry.Bounds grow(javafx.geometry.Bounds r, double h, double v)
      Resizes the Bounds both horizontally and vertically.

      This method returns a new Bounds so that it is h units larger on both the left and right side, and v units larger at both the top and bottom.

      The new Bounds has (x - h, y - v) as its top-left corner, a width of width + 2h, and a height of height + 2v.

      If negative values are supplied for h and v, the size of the Rectangle2D decreases accordingly. The grow method does not check whether the resulting values of width and height are non-negative.

      Parameters:
      r - the bounds
      h - the horizontal expansion
      v - the vertical expansion
      Returns:
      the new rectangle

    • grow

      public static javafx.geometry.Bounds grow(javafx.geometry.Bounds r, double hv)
      Resizes the Bounds both horizontally and vertically.
      Parameters:
      r - the bounds
      hv - the horizontal and vertical expansion
      Returns:
      the new rectangle
