intersectsRectangle
static boolean intersectsRectangle(PathIterator2ai<?> pi, int x, int y, int width, int height)
Tests if the interior of the specifiedPathIterator2ai
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 theintersects()
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 specifiedPathIterator
x
- the specified X coordinatey
- the specified Y coordinatewidth
- the width of the specified rectangular coordinatesheight
- the height of the specified rectangular coordinates- Returns:
true
if the specifiedPathIterator
and the interior of the specified set of rectangular coordinates intersect each other;false
otherwise.

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
andradiusy
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.
