    Accumulate the number of times the path crosses the shadow extending to the right of the rectangle. See the comment for the SHAPE_INTERSECTS constant for more complete details. The return value is the sum of all crossings for both the top and bottom of the shadow for every segment in the path, or the special value SHAPE_INTERSECTS if the path ever enters the interior of the rectangle. The path must start with a SEG_MOVETO, otherwise an exception is thrown. The caller must check r[xy]{min, max} for NaN values.
    
    Parameters:
    
    crossings - the initial crossing.
    
    pi - is the iterator on the path elements.
    
    rxmin - is the first corner of the rectangle.
    
    rymin - is the first corner of the rectangle.
    
    rxmax - is the second corner of the rectangle.
    
    rymax - is the second corner of the rectangle.
    
    type - is the type of special computation to apply. If null, it is equivalent to CrossingComputationType.STANDARD.
    
    Returns:
    
    the crossings.

```
    Tests if the interior of the specified PathIterator2ai intersects the interior of a specified set of rectangular coordinates.
    This method provides a basic facility for implementors of the Shape2ai interface to implement support for the intersects() method.
    This method object may conservatively return true 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 a case may occur if some set of segments of the path are retraced in the reverse direction such that the two sets of segments cancel each other out without any interior area 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.
    
    Parameters:
    
    pi - the specified PathIterator
    
    x - the specified X coordinate
    
    y - the specified Y coordinate
    
    width - the width of the specified rectangular coordinates
    
    height - the height of the specified rectangular coordinates
    
    Returns:
    
    true if the specified PathIterator and the interior of the specified set of rectangular coordinates intersect each other; false otherwise.

                   Path2D.ArcType type)
```
    Adds a section of an shallow ellipse to the current path. The ellipse from which a quadrant is taken is the ellipse that would be inscribed in a parallelogram defined by 3 points, The current point which is considered to be the midpoint of the edge leading into the corner of the ellipse where the ellipse grazes it, (ctrlx, ctrly) which is considered to be the location of the corner of the parallelogram in which the ellipse is inscribed, and (tox, toy) which is considered to be the midpoint of the edge leading away from the corner of the oval where the oval grazes it.
    
    Only the portion of the ellipse from tfrom to tto will be included where 0f represents the point where the ellipse grazes the leading edge, 1f represents the point where the oval grazes the trailing edge, and 0.5f represents the point on the oval closest to the control point. The two values must satisfy the relation (0 <= tfrom <= tto <= 1).
    If tfrom is not 0f then the caller would most likely want to use one of the arc type values that inserts a segment leading to the initial point. An initial moveTo(int, int) or lineTo(int, int) can be added to direct the path to the starting point of the ellipse section if Path2D.ArcType.MOVE_THEN_ARC or Path2D.ArcType.LINE_THEN_ARC are specified by the type argument. The lineTo path segment will only be added if the current point is not already at the indicated location to avoid spurious empty line segments. The type can be specified as Path2D.ArcType.ARC_ONLY if the current point on the path is known to be at the starting point of the ellipse section.
    
    Parameters:
    
    ctrlx - the x coordinate of the control point, i.e. the corner of the parallelogram in which the ellipse is inscribed.
    
    ctrly - the y coordinate of the control point, i.e. the corner of the parallelogram in which the ellipse is inscribed.
    
    tox - the x coordinate of the target point.
    
    toy - the y coordinate of the target point.
    
    tfrom - the fraction of the ellipse section where the curve should start.
    
    tto - the fraction of the ellipse section where the curve should end
    
    type - the specification of what additional path segments should be appended to lead the current path to the starting point.

                   Path2D.ArcType type)
```
    Description copied from interface: Path2D
    
    Adds a section of an shallow ellipse to the current path. The ellipse from which a quadrant is taken is the ellipse that would be inscribed in a parallelogram defined by 3 points, The current point which is considered to be the midpoint of the edge leading into the corner of the ellipse where the ellipse grazes it, (ctrlx, ctrly) which is considered to be the location of the corner of the parallelogram in which the ellipse is inscribed, and (tox, toy) which is considered to be the midpoint of the edge leading away from the corner of the oval where the oval grazes it.
    
    Only the portion of the ellipse from tfrom to tto will be included where 0f represents the point where the ellipse grazes the leading edge, 1f represents the point where the oval grazes the trailing edge, and 0.5f represents the point on the oval closest to the control point. The two values must satisfy the relation (0 <= tfrom <= tto <= 1).
    If tfrom is not 0f then the caller would most likely want to use one of the arc type values that inserts a segment leading to the initial point. An initial Path2D.moveTo(Point2D) or Path2D.lineTo(Point2D) can be added to direct the path to the starting point of the ellipse section if Path2D.ArcType.MOVE_THEN_ARC or Path2D.ArcType.LINE_THEN_ARC are specified by the type argument. The lineTo path segment will only be added if the current point is not already at the indicated location to avoid spurious empty line segments. The type can be specified as Path2D.ArcType.ARC_ONLY if the current point on the path is known to be at the starting point of the ellipse section.

```
    Description copied from interface: Path2D
    Adds a section of an shallow ellipse to the current path. The ellipse from which the portions are extracted follows the rules:
    
    The ellipse will have its X axis tilted from horizontal by the angle xAxisRotation specified in radians.
    
    The ellipse will have the X and Y radii (viewed from its tilted coordinate system) specified by radiusx and radiusy unless that ellipse is too small to bridge the gap from the current point to the specified destination point in which case a larger ellipse with the same ratio of dimensions will be substituted instead.
    
    The ellipse may slide perpendicular to the direction from the current point to the specified destination point so that it just touches the two points. The direction it slides (to the "left" or to the "right") will be chosen to meet the criteria specified by the two boolean flags as described below. Only one direction will allow the method to meet both criteria.
    
    If the largeArcFlag is true, then the ellipse will sweep the longer way around the ellipse that meets these criteria.
    
    If the sweepFlag is true, then the ellipse will sweep clockwise around the ellipse that meets these criteria.
    
    The method will do nothing if the destination point is the same as the current point. The method will draw a simple line segment to the destination point if either of the two radii are zero.

    Parameters:

    radii - the X and Y radii of the tilted ellipse.

  - getPathIterator
```
@Pure
default PathIterator2ai<IE> getPathIterator(double flatness)
```
    Description copied from interface: Path2D
    
    Replies an iterator on the path elements.
    Only PathElementType.MOVE_TO, PathElementType.LINE_TO, and PathElementType.CLOSE types are returned by the iterator.
    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.
    The iterator for this class is not multi-threaded safe.

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