public abstract class RectangularShape extends Shape
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.OUT_BOTTOM, OUT_LEFT, OUT_RIGHT, OUT_TOP, RECT_INTERSECTS

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 BaseTransform
can
be specified so that the coordinates returned in the iteration are
transformed accordingly.
