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.
