The cpdf_curveto() function draws a Bezier curve from the current point to the point (x3, y3) using (x1, y1) and (x2, y2) as control points. 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.
