void pdf_translate (int pdf document, double x-coor, double y-coor)
The pdf_translate() function sets the origin of coordinate system to the point (x-coor, y-coor) relativ the current origin. The following example draws a line from (0, 0) to (200, 200) relative to the initial coordinate system. You have to set the current point after pdf_translate() and before you start drawing more objects.
