void cpdf_text (int pdf document, string text, double x-coor, double y-coor [, int mode [, double orientation [, int alignmode]]])
The cpdf_text() 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. The optional parameter orientation is the rotation of the text in degree. The optional parameter alignmode determines how the text is aligned.
See the ClibPDF documentation for possible values.
