Classes in java.awt.geom used by java.awt Class Description AffineTransform TheAffineTransform
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.Dimension2D TheDimension2D
class is to encapsulate a width and a height dimension.PathIterator ThePathIterator
interface provides the mechanism for objects that implement theShape
interface to return the geometry of their boundary by allowing a caller to retrieve the path of that boundary a segment at a time.Point2D ThePoint2D
class defines a point representing a location in(x,y)
coordinate space.Rectangle2D TheRectangle2D
class describes a rectangle defined by a location(x,y)
and dimension(w x h)
.RectangularShape RectangularShape
is the base class for a number ofShape
objects whose geometry is defined by a rectangular frame.
