java.lang.Object org.jaitools.imageutils.shape.LiteShape
public class LiteShape
A thin wrapper that adapts a JTS geometry to the Shape interface so that the geometry can be used by java2d without coordinate cloning.
This class was ported back and simplified from GeoTools, with permission from the author(s).

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.

there is no guarantee that the returned Rectangle2D

smallest bounding box that encloses the Shape
, only that
the Shape
lies entirely within the indicated
Rectangle2D
. 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
that uses double precision
values to store the dimensions.

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.

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.
