  • Method Details

    • twoShapeLayout

      public static TwoShapeLayout twoShapeLayout(Dimension canvas, Dimension upper, Dimension lower, TwoShapeLayouts.TwoShapeLayoutSpec spec)
      Compose two shapes on a canvas. It is guaranteed that shapes to not extend the underlying canvas.
      Parameters:
      canvas - the dimension of the target canvas
      upper - the dimension of the upper (z-axis) source shape
      lower - the dimension of the lower (z-axis) source shape
      spec - the layout specification

    • multiShapeLayout

      public static MultiShapeLayout multiShapeLayout(Dimension canvas, List<org.opencastproject.util.data.Tuple<Dimension,HorizontalCoverageLayoutSpec>> shapes)
      Compose a list of shapes on a canvas.
      Parameters:
      canvas - the dimension of the target canvas
      shapes - A list of shapes sorted in z-order with the first shape in the list being the lowermost one. The list consists of the dimension of the source shape tupled with a layout specification.

    • absoluteMultiShapeLayout

      public static MultiShapeLayout absoluteMultiShapeLayout(Dimension canvas, List<org.opencastproject.util.data.Tuple<Dimension,AbsolutePositionLayoutSpec>> shapes)
      Compose a list of shapes on a canvas.
      Parameters:
      canvas - the dimension of the target canvas
      shapes - A list of shapes sorted in z-order with the first shape in the list being the lowermost one. The list consists of the dimension of the source shape tupled with a layout specification.

    • overlap

      public static boolean overlap(Layout a, Layout b)
      Test if layouts a and b overlap.

    • left

      public static int left(Layout a)
      Get the X coordinate of the left bound of the layout.

    • right

      public static int right(Layout a)

    • scale

      public static Dimension scale(Dimension limit, Dimension shape, double scale)
      Scale shape by scale and ensure that any rounding errors are limited so that the resulting dimension does not exceed limit.
