void cpdf_set_text_pos
(int pdf document, float x-coor, float y-coor [, int mode])
The cpdf_set_text_pos() function sets the position of text for the next cpdf_show() function call.
The optional parameter mode determines the unit length. If it's 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.
