function chilkatExample() {

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var pdf = new chilkat.Pdf();

    // Load a PDF containing 2 remaining unsigned signature fields:
    success = pdf.LoadFile("qa_data/pdf/doctor_patient_parent.pdf");
    if (success == false) {

    // To iterate over the field names:
