public class LiteShape extends Object implements Shape, Cloneable
This implementation supports the use of addineTransform and has a hard coded decimation stratagy (so you can skip points within the same pixel producing a Shape that is "more simple" than the origional Geometry).

public Rectangle getBounds()
Rectangle
that completely encloses the Shape
. Note
that there is no guarantee that the returned Rectangle
is the smallest bounding
box that encloses the Shape
, only that the Shape
lies entirely
within the indicated Rectangle
. The returned Rectangle
might also
fail to completely enclose the Shape
if the Shape
overflows the
limited range of the integer data type. The getBounds2D
method generally returns
a tighter bounding box due to its greater flexibility in representation.getBounds

is the smallest bounding box that encloses the Shape

. The bounding
box returned by this method is usually tighter than that returned by the getBounds
method and never fails due to overflow problems since the return value can be an
instance of the Rectangle2D

access to the geometry of the Shape
outline. If an optional AffineTransform
is specified, the coordinates returned in the iteration are transformed
accordingly.
Each call to this method returns a fresh PathIterator
object that traverses
the geometry of the Shape
object independently from any other PathIterator
objects in use at the same time.
It is recommended, but not guaranteed, that objects implementing the Shape
interface isolate iterations that are in process from any changes that might occur to the
original object's geometry during such iterations.
Before using a particular implementation of the Shape
interface in more than
one thread simultaneously, refer to its documentation to verify that it guarantees that
iterations are isolated from modifications.

access to a flattened view of the Shape
outline geometry.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator.
If an optional AffineTransform
is specified, the coordinates returned in the
iteration are transformed accordingly.
The amount of subdivision of the curved segments is controlled by the flatness
parameter, which specifies the maximum distance that any point on the unflattened
transformed curve can deviate from the returned flattened path segments. Note that a limit on
the accuracy of the flattened path might be silently imposed, causing very small flattening
parameters to be treated as larger values. This limit, if there is one, is defined by the
particular implementation that is used.
