Method Detail

• toString

  public static String toString(Shape s)

  This describes a shape in a String. The model is used is based on how SVG encodes shape data.

  The call:
  ShapeUtils.createPathIterator(ShapeUtils.toString(shape));
  should result in an identical shape.

  The shape data is formatted as a single letter (m, l, q, c, z) followed by the appropriate number of points (2, 2, 4, 6, 0 respectively). This uses floats, not doubles, so it will not contain strings with an exponent (i.e. "1.3e-4").

  Parameters:

  s - the shape to describe

  Returns:

  textual representation of that shape.

• toString

  public static String toString(PathIterator i)

• createPathIterator

  public static PathIterator createPathIterator(String s)

  This creates a PathIterator that iterates over the text in s.

  The shape returned uses winding rule WIND_EVEN_ODD.

  Parameters:

  s - textual representation of a path.

  This should be the output of ShapeUtils.toString(), resembling: "m 1 2 l 3 4 q 5 6 7 8 c 9 10 11 12 13 14 z"

  Returns:

  a PathIterator that will iterate over the data in s.

• createGeneralPath

  public static GeneralPath createGeneralPath(String s)

  This creates a GeneralPath of rule WIND_EVEN_ODD that represents this shape data.

  This method simply calls:
  GeneralPath p = new GeneralPath();
p.append(createPathIterator(s),true);
return p;

  Parameters:

  s - textual representation of a path.

  This should be the output of ShapeUtils.toString(), resembling: "m 1 2 l 3 4 q 5 6 7 8 c 9 10 11 12 13 14 z"

  Returns:

  a GeneralPath that represents this shape.

• createPathIterator

  public static PathIterator createPathIterator(String s,
                                                int windingRule)

  This creates a PathIterator that iterates over the text in s.

  Parameters:

  s - textual representation of a path.

  windingRule - the winding rule to use. (This should be PathIterator.WIND_NON_ZERO or PathIterator.WIND_EVEN_ODD.)

  This should be the output of ShapeUtils.toString(), resembling: "m 1 2 l 3 4 q 5 6 7 8 c 9 10 11 12 13 14 z"

  Returns:

  a PathIterator that will iterate over the data in s.
