Name

intersection_circle_contour_xldintersection_circle_contour_xldIntersectionCircleContourXldIntersectionCircleContourXld — Calculate the intersection points of a circle or circular arc and an XLD contour

Signature

Description

intersection_circle_contour_xldintersection_circle_contour_xldIntersectionCircleContourXldIntersectionCircleContourXldIntersectionCircleContourXld calculates the intersection points of a circle or circular arc and the XLD ContourContourContourContourcontour. The circle is defined by its center (CircleRowCircleRowCircleRowCircleRowcircleRow,CircleColumnCircleColumnCircleColumnCircleColumncircleColumn) and its radius CircleRadiusCircleRadiusCircleRadiusCircleRadiuscircleRadius. In addition to that, a circular arc is characterized by the angle of the start point CircleStartPhiCircleStartPhiCircleStartPhiCircleStartPhicircleStartPhi, the angle of the end point CircleEndPhiCircleEndPhiCircleEndPhiCircleEndPhicircleEndPhi, and the point order CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder along the boundary. If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder is set to 'positive'"positive""positive""positive""positive", the circular arc is defined counterclockwise. If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder is set to 'negative'"negative""negative""negative""negative", the circular arc is defined clockwise. The intersection points, if any, are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn).
