intersectsPixelClosure method
Test whether the given segment intersects the closure of this hot pixel. This is NOT the test used in the standard snap-rounding algorithm, which uses the partially closed tolerance square instead. This routine is provided for testing purposes only.
@param p0 the start point of a line segment
@param p1 the end point of a line segment
@return true
if the segment intersects the closure of the pixel's tolerance square
Implementation
bool intersectsPixelClosure(Coordinate p0, Coordinate p1) {
li.computeIntersection(p0, p1, corner[0], corner[1]);
if (li.hasIntersection()) return true;
li.computeIntersection(p0, p1, corner[1], corner[2]);
if (li.hasIntersection()) return true;
li.computeIntersection(p0, p1, corner[2], corner[3]);
if (li.hasIntersection()) return true;
li.computeIntersection(p0, p1, corner[3], corner[0]);
if (li.hasIntersection()) return true;
return false;
