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

* The signed PDF produced by this example should be verifiable at https://verificador.iti.gov.br/verifier-2.10/
loPdf = CreateObject('Chilkat_9_5_0.Pdf')

* Load a PDF to be signed.
* The "hello.pdf" is available at https://chilkatsoft.com/hello.pdf

IF (lnSuccess = 0) THEN
    ? loPdf.LastErrorText
    RELEASE loPdf
    CANCEL
ENDIF

loJson = CreateObject('Chilkat_9_5_0.JsonObject')

* Define the appearance and location of the signature.
loJson.UpdateInt("page",1)
loJson.UpdateString("appearance.y","bottom")
loJson.UpdateString("appearance.x","middle")
loJson.UpdateString("appearance.fontScale","9.0")
