bool cpdf_add_annotation ( int pdf_document, float llx, float lly, float urx, float ury, string title, string content [, int mode] )

The cpdf_add_annotation() adds a note with the lower left corner at (llx, lly) and the upper right corner at (urx, ury). Returns TRUE on success or FALSE on failure.
