Package java.awt.geom
package java.awt.geom
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.

ClassDescriptionThe
AffineTransformclass 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.Arc2Dis 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, orPIE).This class defines an arc specified indoubleprecision.This class defines an arc specified infloatprecision.AnAreaobject stores and manipulates a resolution-independent description of an enclosed area of 2-dimensional space.TheCubicCurve2Dclass defines a cubic parametric curve segment in(x,y)coordinate space.A cubic parametric curve segment specified withdoublecoordinates.A cubic parametric curve segment specified withfloatcoordinates.TheDimension2Dclass is to encapsulate a width and a height dimension.TheEllipse2Dclass describes an ellipse that is defined by a framing rectangle.TheDoubleclass defines an ellipse specified indoubleprecision.TheFloatclass defines an ellipse specified infloatprecision.TheFlatteningPathIteratorclass returns a flattened view of anotherPathIteratorobject.TheGeneralPathclass represents a geometric path constructed from straight lines, and quadratic and cubic (Bézier) curves.TheIllegalPathStateExceptionrepresents 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 aGeneralPathwithout an initial moveto.ThisLine2Drepresents a line segment in(x,y)coordinate space.A line segment specified with double coordinates.A line segment specified with float coordinates.TheNoninvertibleTransformExceptionclass represents an exception that is thrown if an operation is performed requiring the inverse of anAffineTransformobject but theAffineTransformis in a non-invertible state.ThePath2Dclass provides a simple, yet flexible shape which represents an arbitrary geometric path.TheDoubleclass defines a geometric path with coordinates stored in double precision floating point.TheFloatclass defines a geometric path with coordinates stored in single precision floating point.ThePathIteratorinterface provides the mechanism for objects that implement theShapeinterface to return the geometry of their boundary by allowing a caller to retrieve the path of that boundary a segment at a time.ThePoint2Dclass defines a point representing a location in(x,y)coordinate space.TheDoubleclass defines a point specified indoubleprecision.TheFloatclass defines a point specified in float precision.TheQuadCurve2Dclass defines a quadratic parametric curve segment in(x,y)coordinate space.A quadratic parametric curve segment specified withdoublecoordinates.A quadratic parametric curve segment specified withfloatcoordinates.TheRectangle2Dclass describes a rectangle defined by a location(x,y)and dimension(w x h).TheDoubleclass defines a rectangle specified in double coordinates.TheFloatclass defines a rectangle specified in float coordinates.RectangularShapeis the base class for a number ofShapeobjects whose geometry is defined by a rectangular frame.TheRoundRectangle2Dclass 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.TheDoubleclass defines a rectangle with rounded corners all specified indoublecoordinates.TheFloatclass defines a rectangle with rounded corners all specified infloatcoordinates.
