The cpdf_show_xy() function outputs the string text at position with coordinates (x-coor, y-coor).
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.
Note: The function cpdf_show_xy() is identical to cpdf_text() without the optional parameters.
