public interface Shape2D
extends java.awt.Shape

Main interface for all geometric objects, including points, lines, curves, or planar regions...

Depending direct interfaces extending Shape2D are Curve2D, and AbstractDomain2D. There are some direct implementation of Shape2D: Point2D, Shape2D.EmptySet2D.

Field Summary

static double	ACCURACY The constant used for testing results.
static Box2D	defaultClipWindow This is the basic window used by default to clip lines, conics or others infinite figures to draw them.
static Shape2D	EMPTY_SET

Method Summary

Shape2D	clip(Box2D box) Clip the shape with the given box, and returns a new shape.
Box2D	getBoundingBox() Returns the bounding box of the shape.
double	getDistance(double x, double y) get the distance of the shape to the given point, specified by x and y, or the distance of point to the frontier of the shape in the case of a plain (i.e. fillable) shape.
double	getDistance(java.awt.geom.Point2D p) get the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.
boolean	isBounded() Returns true if the shape is bounded, that is if we can draw a finite rectangle enclosing the shape.
Shape2D	transform(AffineTransform2D trans) transform the shape by an affine transform.

Field Detail

ACCURACY

static final double ACCURACY

The constant used for testing results.

Constant Field Values

defaultClipWindow

static final Box2D defaultClipWindow

This is the basic window used by default to clip lines, conics or others infinite figures to draw them. To override this default window, use Shape2D.getClippedShape(Rectangle2D), which always returns a 'finite' shape.

EMPTY_SET

static final Shape2D EMPTY_SET

Method Detail

getDistance

double getDistance(java.awt.geom.Point2D p)

get the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.

getDistance

double getDistance(double x,
                   double y)

get the distance of the shape to the given point, specified by x and y, or the distance of point to the frontier of the shape in the case of a plain (i.e. fillable) shape.

isBounded

boolean isBounded()

Returns true if the shape is bounded, that is if we can draw a finite rectangle enclosing the shape. For example, a straight line or a parabola are not bounded.

clip

Shape2D clip(Box2D box)

Clip the shape with the given box, and returns a new shape.

Parameters:

box - the clipping box

Returns:

the clipped shape

getBoundingBox

Box2D getBoundingBox()

Returns the bounding box of the shape.

Returns:

the bounding box of the shape.

transform

Shape2D transform(AffineTransform2D trans)

transform the shape by an affine transform. Subclasses may override the type of returned shape.

Parameters:

trans - an affine transform

Returns:

the transformed shape
