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

pdf = chilkat.CkPdf()

# Load a PDF containing 2 remaining unsigned signature fields:
success = pdf.LoadFile("qa_data/pdf/doctor_patient_parent.pdf")
if (success == False):
    print(pdf.lastErrorText())
    sys.exit()

# Note: This example requires Chilkat v9.5.0.90 or greater.
json = chilkat.CkJsonObject()
pdf.GetUnsignedSigFields(json)

json.put_EmitCompact(False)
print(json.emit())

# Result:
# {
#   "unsignedSigField": [
#     "doctor_signature",
#     "parent_signature"
#   ]
# }

# To iterate over the field names:

i = 0
count_i = json.SizeOfArray("unsignedSigField")
while i < count_i :
    json.put_I(i)
    strVal = json.stringOf("unsignedSigField[i]")
    print(strVal)
    i = i + 1
