 java.awt.geom.FlatteningPathIterator
| FlatteningPathIterator | | public class FlatteningPathIterator implements PathIterator(Code) | | The FlatteningPathIterator class returns a flattened view of
another
PathIterator object. Other
java.awt.Shape Shape
classes can use this class to provide flattening behavior for their paths
without having to perform the interpolation calculations themselves.

| Constructor Summary | |
| public | FlatteningPathIterator(PathIterator src, double flatness)
Constructs a new FlatteningPathIterator object that
flattens a path as it iterates over it. | | public | FlatteningPathIterator(PathIterator src, double flatness, int limit)
Constructs a new FlatteningPathIterator object
that flattens a path as it iterates over it. |
| Method Summary | |
| public int | currentSegment(float[] coords)
Returns the coordinates and type of the current path segment in
the iteration.
The return value is the path segment type:
SEG_MOVETO, SEG_LINETO, or SEG_CLOSE.
A float array of length 6 must be passed in and can be used to
store the coordinates of the point(s).
Each point is stored as a pair of float x,y coordinates.
SEG_MOVETO and SEG_LINETO types return one point,
and SEG_CLOSE does not return any points.
Parameters:
coords - an array that holds the data returned fromthis method the path segment type of the current path segment. | | public int | currentSegment(double[] coords)
Returns the coordinates and type of the current path segment in
the iteration.
The return value is the path segment type:
SEG_MOVETO, SEG_LINETO, or SEG_CLOSE.
A double array of length 6 must be passed in and can be used to
store the coordinates of the point(s).
Each point is stored as a pair of double x,y coordinates.
SEG_MOVETO and SEG_LINETO types return one point,
and SEG_CLOSE does not return any points.
Parameters:
coords - an array that holds the data returned fromthis method the path segment type of the current path segment. | | void | ensureHoldCapacity(int want)
| | public double | getFlatness()
Returns the flatness of this iterator. | | public int | getRecursionLimit()
Returns the recursion limit of this iterator. | | public int | getWindingRule()
Returns the winding rule for determining the interior of the
path. | | public boolean | isDone()
Tests if the iteration is complete. | | public void | next()
Moves the iterator to the next segment of the path forwards
along the primary direction of traversal as long as there are
more points in that direction. |
| GROW_SIZE | | final static int GROW_SIZE(Code) | | |
| curxcury | | double curxcury(Code) | | |

| movxmovy | | double movxmovy(Code) | | |
| squareflat | | double squareflat(Code) | | |
| FlatteningPathIterator | | public FlatteningPathIterator(PathIterator src, double flatness)(Code) | | Constructs a new FlatteningPathIterator object that
flattens a path as it iterates over it. The iterator does not
subdivide any curve read from the source iterator to more than
10 levels of subdivision which yields a maximum of 1024 line
segments per curve.
Parameters:
src - the original unflattened path being iterated over
Parameters:
flatness - the maximum allowable distance between thecontrol points and the flattened curve |
| FlatteningPathIterator | | public FlatteningPathIterator(PathIterator src, double flatness, int limit)(Code) | | Constructs a new FlatteningPathIterator object
that flattens a path as it iterates over it.
The limit parameter allows you to control the
maximum number of recursive subdivisions that the iterator
can make before it assumes that the curve is flat enough
without measuring against the flatness parameter.
The flattened iteration therefore never generates more than
a maximum of (2^limit) line segments per curve.
Parameters:
src - the original unflattened path being iterated over
Parameters:
flatness - the maximum allowable distance between thecontrol points and the flattened curve
Parameters:
limit - the maximum number of recursive subdivisionsallowed for any curved segment IllegalArgumentException if flatness or limitis less than zero |
| currentSegment | | public int currentSegment(float[] coords)(Code) | | Returns the coordinates and type of the current path segment in
the iteration.
The return value is the path segment type:
SEG_MOVETO, SEG_LINETO, or SEG_CLOSE.
A float array of length 6 must be passed in and can be used to
store the coordinates of the point(s).
Each point is stored as a pair of float x,y coordinates.
SEG_MOVETO and SEG_LINETO types return one point,
and SEG_CLOSE does not return any points.
Parameters:
coords - an array that holds the data returned fromthis method the path segment type of the current path segment. NoSuchElementException if thereare no more elements in the flattening path to bereturned.
