描述
gen_circle_contour_xldgen_circle_contour_xldGenCircleContourXldGenCircleContourXldGenCircleContourXldgen_circle_contour_xld creates one or more circular arcs or
closed circles. Circles are specified by their center
(RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn) and their RadiusRadiusRadiusRadiusradiusradius.
In addition to that, circular arcs are characterized by the angle
of the start point StartPhiStartPhiStartPhiStartPhistartPhistart_phi, the angle of the end point
EndPhiEndPhiEndPhiEndPhiendPhiend_phi, and the PointOrderPointOrderPointOrderPointOrderpointOrderpoint_order along the
boundary.
The resolution of the resulting contours ContCircleContCircleContCircleContCirclecontCirclecont_circle is
controlled via ResolutionResolutionResolutionResolutionresolutionresolution containing the Euclidean
distance in pixel between neighboring contour points. In general,
the distance between the second to last and the last point is smaller
than ResolutionResolutionResolutionResolutionresolutionresolution。
