Method Detail

• isValid

  public static boolean isValid(Shape shape)

  Return false if any coordinates in this shape contain NaN or Infinite values.

• traceShape

  public static GeneralPath traceShape(Shape shape,
                                       float progress)

  This traces the shape provided. This can be used to create a "drawing" effect.

  This assumes every segment is equally important/long, which is not always the case.

  Parameters:

  shape -

  progress - a float from [0,1], indicating what fraction of the shape provided should be traced.

  Returns:

  a portion of the shape provided

• getPoint

  public static Point2D getPoint(Shape shape,
                                 float progress)

  TSimilar to tracing, this progresses a dot from the beginning to the end of this path.

  Parameters:

  shape -

  progress - a float from [0,1]

• getSubPathCount

  public static int getSubPathCount(Shape s)

  Returns the number of separate paths in the shape provided.

• getSubPaths

  public static GeneralPath[] getSubPaths(Shape s)

  Returns each path in s as a separate GeneralPath

• equals

  public static boolean equals(Shape shape,
                               Shape shape2)

  Return true if two shapes are equal.

• isClosed

  public static boolean isClosed(Shape shape)

  Return true if every subpath in the shape provided is closed.

  Parameters:

  shape - the shape to inspect

  Returns:

  true if every subpath in the shape provided ends with a SEG_CLOSE.
