public abstract class Path2D extends Object implements Shape, Cloneable
The Path2D
class provides a simple, yet flexible shape which represents an arbitrary geometric path. It can fully represent any path which can be iterated by the PathIterator
interface including all of its segment types and winding rules and it implements all of the basic hit testing methods of the Shape
interface.
Use Path2D.Float
when dealing with data that can be represented and used with floating point precision. Use Path2D.Double
for data that requires the accuracy or range of double precision.
Path2D
provides exactly those facilities required for basic construction and management of a geometric path and implementation of the above interfaces with little added interpretation. If it is useful to manipulate the interiors of closed geometric shapes beyond simple hit testing then the Area
class provides additional capabilities specifically targeted at closed figures. While both classes nominally implement the Shape
interface, they differ in purpose and together they provide two useful views of a geometric shape where Path2D
deals primarily with a trajectory formed by path segments and Area
deals more with interpretation and manipulation of enclosed regions of 2D geometric space.
The PathIterator
interface has more detailed descriptions of the types of segments that make up a path and the winding rules that control how to determine which regions are inside or outside the path.

Point2D
object containing the ending coordinates of the path ornull

createTransformedShape
public final Shape createTransformedShape(AffineTransform at)
Returns a new Shape
representing a transformed version of this Path2D
. Note that the exact type and coordinate precision of the return value is not specified for this method. The method will return a Shape that contains no less precision for the transformed geometry than this Path2D
currently maintains, but it may contain no more precision either. If the tradeoff of precision vs. storage size in the result is important then the convenience constructors in the Path2D.Float
and Path2D.Double
subclasses should be used to make the choice explicit.
- Parameters:
-

- theAffineTransform
used to transform a newShape
. - Returns:
- a new
Shape
, transformed with the specifiedAffineTransform
. - Since:
- 1.6
getBounds
public final Rectangle getBounds()
Returns an integer Rectangle
that completely encloses the Shape
. Note that there is no guarantee that the returned Rectangle
is the smallest bounding box that encloses the Shape
, only that the Shape
lies entirely within the indicated Rectangle
. The returned Rectangle
might also fail to completely enclose the Shape
if the Shape
overflows the limited range of the integer data type. The getBounds2D
method generally returns a tighter bounding box due to its greater flexibility in representation.
Note that the definition of insideness can lead to situations where points on the defining outline of the shape
may not be considered contained in the returned bounds
object, but only in cases where those points are also not considered contained in the original shape
.
If a point
is inside the shape
according to the contains(point)
method, then it must be inside the returned Rectangle
bounds object according to the contains(point)
method of the bounds
. Specifically:
shape.contains(x,y)
requires bounds.contains(x,y)
If a point
is not inside the shape
, then it might still be contained in the bounds
object:
bounds.contains(x,y)
does not imply shape.contains(x,y)
- Specified by:

- an integer
Rectangle
that completely encloses theShape
. - Since:

public static boolean contains(PathIterator pi, double x, double y, double w, double h)
Tests if the specified rectangular area is entirely inside the closed boundary of the specified PathIterator
.
This method provides a basic facility for implementors of the Shape
interface to implement support for the Shape.contains(double, double, double, double)
method.
This method object may conservatively return false in cases where the specified rectangular area intersects a segment of the path, but that segment does not represent a boundary between the interior and exterior of the path. Such segments could lie entirely within the interior of the path if they are part of a path with a WIND_NON_ZERO
winding rule or if the segments are retraced in the reverse direction such that the two sets of segments cancel each other out without any exterior area falling between them. To determine whether segments represent true boundaries of the interior of the path would require extensive calculations involving all of the segments of the path and the winding rule and are thus beyond the scope of this implementation.

getPathIterator
public final PathIterator getPathIterator(AffineTransform at, double flatness)
Returns an iterator object that iterates along the Shape
boundary and provides access to a flattened view of the Shape
outline geometry.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator.
If an optional AffineTransform
is specified, the coordinates returned in the iteration are transformed accordingly.
The amount of subdivision of the curved segments is controlled by the flatness
parameter, which specifies the maximum distance that any point on the unflattened transformed curve can deviate from the returned flattened path segments. Note that a limit on the accuracy of the flattened path might be silently imposed, causing very small flattening parameters to be treated as larger values. This limit, if there is one, is defined by the particular implementation that is used.
Each call to this method returns a fresh PathIterator
object that traverses the Shape
object geometry independently from any other PathIterator
objects in use at the same time.
It is recommended, but not guaranteed, that objects implementing the Shape
interface isolate iterations that are in process from any changes that might occur to the original object's geometry during such iterations.
The iterator for this class is not multi-threaded safe, which means that this Path2D
class does not guarantee that modifications to the geometry of this Path2D
object do not affect any iterations of that geometry that are already in process.

- Parameters:
-

- an optionalAffineTransform
to be applied to the coordinates as they are returned in the iteration, ornull

- the maximum distance that the line segments used to approximate the curved segments are allowed to deviate from any point on the original curve - Returns:
