The AffineTransform class represents a 2D affine transform
that performs a linear mapping from 2D coordinates to other 2D
coordinates that preserves the "straightness" and
"parallelness" of lines.
Arc2D is the abstract superclass for all objects that
store a 2D arc defined by a framing rectangle,
start angle, angular extent (length of the arc), and a closure type
(OPEN, CHORD, or PIE).
This class defines an arc specified in double precision.
This class defines an arc specified in float precision.
An Area object stores and manipulates a
resolution-independent description of an enclosed area of
2-dimensional space.
The CubicCurve2D class defines a cubic parametric curve
segment in (x,y) coordinate space.
A cubic parametric curve segment specified with
double coordinates.
A cubic parametric curve segment specified with
float coordinates.
The Dimension2D class is to encapsulate a width
and a height dimension.
The Ellipse2D class describes an ellipse that is defined
by a framing rectangle.
The Double class defines an ellipse specified
in double precision.
The Float class defines an ellipse specified
in float precision.
The FlatteningPathIterator class returns a flattened view of
another PathIterator object.
The GeneralPath class represents a geometric path
constructed from straight lines, and quadratic and cubic
(Bézier) curves.
The IllegalPathStateException represents an
exception that is thrown if an operation is performed on a path
that is in an illegal state with respect to the particular
operation being performed, such as appending a path segment
to a GeneralPath without an initial moveto.
This Line2D represents a line segment in (x,y)
coordinate space.
A line segment specified with double coordinates.
A line segment specified with float coordinates.
The NoninvertibleTransformException class represents
an exception that is thrown if an operation is performed requiring
the inverse of an AffineTransform object but the
AffineTransform is in a non-invertible state.
The Path2D class provides a simple, yet flexible
shape which represents an arbitrary geometric path.
The Double class defines a geometric path with
coordinates stored in double precision floating point.
The Float class defines a geometric path with
coordinates stored in single precision floating point.
The PathIterator interface provides the mechanism
for objects that implement the Shape
interface to return the geometry of their boundary by allowing
a caller to retrieve the path of that boundary a segment at a
time.
The Point2D class defines a point representing a location
in (x,y) coordinate space.
The Double class defines a point specified in
double precision.
The Float class defines a point specified in float
precision.
The QuadCurve2D class defines a quadratic parametric curve
segment in (x,y) coordinate space.
A quadratic parametric curve segment specified with
double coordinates.
A quadratic parametric curve segment specified with
float coordinates.
The Rectangle2D class describes a rectangle
defined by a location (x,y) and dimension
(w x h).
The Double class defines a rectangle specified in
double coordinates.
The Float class defines a rectangle specified in float
coordinates.
RectangularShape is the base class for a number of
Shape objects whose geometry is defined by a rectangular frame.
The RoundRectangle2D class defines a rectangle with
rounded corners defined by a location (x,y), a
dimension (w x h), and the width and height of an arc
with which to round the corners.
The Double class defines a rectangle with rounded
corners all specified in double coordinates.
The Float class defines a rectangle with rounded
corners all specified in float coordinates.
