Description

gen_circle_contour_xldgen_circle_contour_xldGenCircleContourXldGenCircleContourXldGenCircleContourXld creates one or more circular arcs or closed circles. Circles are specified by their center (RowRowRowRowrow, ColumnColumnColumnColumncolumn) and their RadiusRadiusRadiusRadiusradius. In addition to that, circular arcs are characterized by the angle of the start point StartPhiStartPhiStartPhiStartPhistartPhi, the angle of the end point EndPhiEndPhiEndPhiEndPhiendPhi, and the PointOrderPointOrderPointOrderPointOrderpointOrder along the boundary. The resolution of the resulting contours ContCircleContCircleContCircleContCirclecontCircle is controlled via ResolutionResolutionResolutionResolutionresolution 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 ResolutionResolutionResolutionResolutionresolution.
