bool cpdf_curveto ( int $pdf_document , float $x1 , float $y1 , float $x2 , float $y2 , float $x3 , float $y3 [, int $mode ] )

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

pdf_document: The document handle, returned by cpdf_open().
x1: x-coordinate for the first control point
y1: y-coordinate for the first control point
x2: x-coordinate for the second control point
y2: y-coordinate for the second control point
x3: x-coordinate for the target
y3: y-coordinate for the target
mode: 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.

如果成功则返回 TRUE，失败则返回 FALSE。
