| RectangularShape | | abstract public class RectangularShape implements Shape,Cloneable(Code) | | RectangularShape is the base class for a number of
Shape objects whose geometry is defined by a rectangular frame.
This class does not directly specify any specific geometry by
itself, but merely provides manipulation methods inherited by
a whole category of Shape objects.
The manipulation methods provided by this class can be used to
query and modify the rectangular frame, which provides a reference
for the subclasses to define their geometry.

| getPathIterator | | public PathIterator getPathIterator(AffineTransform at, double flatness)(Code) | | Returns an iterator object that iterates along the
Shape object's boundary and provides access to a
flattened view of the outline of the Shape
object's geometry.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types will
be returned by the iterator.
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.
An optional
AffineTransform can
be specified so that the coordinates returned in the iteration are
transformed accordingly.
Parameters:
at - an optional AffineTransform to be applied to thecoordinates as they are returned in the iteration, or null if untransformed coordinates are desired.
Parameters:
flatness - the maximum distance that the line segments used toapproximate the curved segments are allowed to deviatefrom any point on the original curve a PathIterator object that provides access to the Shape object's flattened geometry.
