The arc starts at an angle of alpha and ends at an angle of beta. It is drawn counterclockwise (use ps_arcn to draw clockwise). The subpath added to the current path starts on the arc at angle alpha and ends on the arc at angle beta. &reftitle.parameters; psdoc Resource identifier of the postscript file as returned by ps_new. x The x-coordinate of the circle's middle point. y The y-coordinate of the circle's middle point. radius The radius of the circle alpha The start angle given in degrees. beta The end angle given in degrees. &reftitle.returnvalues; &return.success; &reftitle.seealso; ps_arcn
