The cpdf_arc() function draws an arc with center at point (x_coor, y_coor) and radius radius, starting at angle start and ending at angle end. Επιστρέφει TRUE σε επιτυχία ή FALSE σε αποτυχία.
The optional parameter mode determines the unit length. If it is 0 or omitted the default unit as specified for the page is used. Otherwise the coordinates are measured in postscript points disregarding the current unit.
