Interface Summary

PathIterator

The iteration interface for objects which traverse the geometric outline of the boundary of an object which implements the Shape interface.

Class Summary

AffineTransform	This class represents a 2D affine transform which performs a linear mapping from 2D coordinates to other 2D coordinates in a manner which preserves the "straightness" and "parallelness" of lines.
Arc2D	An arc defined by a bounding rectangle, start angle and angular extent, and a closure type (one of OPEN, CHORD, or PIE).
Arc2D.Double	An arc specified in double precision,
Arc2D.Float	An arc specified in float precision,
Area	Area is a device-independent specification of an arbitrarily-shaped area.
CubicCurve2D	A cubic parametric curve segment in (x, y) coordinate space.
CubicCurve2D.Double	A cubic parametric curve segment specified with double coordinates.
CubicCurve2D.Float	A cubic parametric curve segment specified with float coordinates.
Dimension2D	A class to encapsulate a width and a height Dimension.
Ellipse2D	An ellipse defined by a bounding rectangle.
Ellipse2D.Double	An ellipse specified in double precision.
Ellipse2D.Float	An ellipse specified in float precision.
FlatteningPathIterator	This class returns a flattened view of another PathIterator object.
GeneralPath	This class represents a geometric path constructed from straight lines, quadratic and cubic (Bezier) curves.
Line2D	A line segment in (x, y) coordinate space.
Line2D.Double	A line segment specified with double coordinates.
Line2D.Float	A line segment specified with float coordinates.
Point2D	A point representing a location in (x, y) coordinate space.
Point2D.Double	A point specified in double precision.
Point2D.Float	A point specified in float precision.
QuadCurve2D	A quadratic parametric curve segment in (x, y) coordinate space.
QuadCurve2D.Double	A quadratic parametric curve segment specified with double coordinates.
QuadCurve2D.Float	A quadratic parametric curve segment specified with float coordinates.
Rectangle2D	A rectangle defined by a location (x, y) and dimension (w x h).
Rectangle2D.Double	A rectangle specified in double coordinates.
Rectangle2D.Float	A rectangle specified in float coordinates.
RectangularShape	The base class for a number of shapes whose geometry is defined by a rectangular frame.
RoundRectangle2D	A rectangle with rounded corners defined by a location (x, y), a dimension (w x h), and the width and height of an arc to round the corners with.
RoundRectangle2D.Double	A rectangle with rounded corners all specified in double coordinates.
RoundRectangle2D.Float	A rectangle with rounded corners all specified in float coordinates.

Exception Summary

IllegalPathStateException	This exception is thrown if an operation is performed on a path in an illegal state, such as appending a path segment without an initial moveto.
NoninvertibleTransformException	This exception is thrown if an operation is performed requiring the inverse of a Transform object and the Transform is not invertible.

Package java.awt.geom Description

Provides the Java 2D classes for defining and performing operations on objects related to two-dimensional geometry. Some important features of the package include:

• classes for manipulating geometry, such as AffineTransform and the PathIterator interface which is implemented by all Shape objects.
• classes that implement the Shape interface, such as CubicCurve2D, Ellipse2D, Line2D, Rectangle2D, and GeneralShape.
• the Area class which provides mechanisms for add (union), subtract, intersect, and exclusiveOR operations on other Shape objects.
