(AutoIt) PDF Signatures with Built-in SVG GraphicsSee more PDF Signatures ExamplesThis example demonstrates the built-in SVG graphics that can be applied to the appearance when signing a PDF. Note: This example requires Chilkat v9.5.0.85 or greater.
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. $oPdf = ObjCreate("Chilkat.Pdf") ; Load a PDF to be signed. ; The "hello.pdf" is available at https://chilkatsoft.com/hello.pdf Local $bSuccess = $oPdf.LoadFile("qa_data/pdf/hello.pdf") If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf ; Options for signing are specified in JSON. $oJson = ObjCreate("Chilkat.JsonObject") ; In most cases, the signingCertificateV2 and signingTime attributes are required. $oJson.UpdateInt("signingCertificateV2",1) $oJson.UpdateInt("signingTime",1) ; Specify the location/position, scale, and content of the signature's appearance. $oJson.UpdateInt("page",1) $oJson.UpdateString("appearance.y","top") $oJson.UpdateString("appearance.x","left") $oJson.UpdateString("appearance.fontScale","10.0") $oJson.UpdateString("appearance.text[0]","Digitally signed by: cert_cn") $oJson.UpdateString("appearance.text[1]","current_dt") $oJson.UpdateString("appearance.text[2]","The crazy brown fox jumps over the lazy dog.") ; In addition to the above, this example adds a built-in SVG graphic to the appearance. ; The built-in SVG graphic is specified by a name, such as "green-check-grey-circle". ; The full list of graphic names and images are shown below. $oJson.UpdateString("appearance.image","green-check-grey-circle") ; The graphic can be placed "left", "center", or "right". ; If "center", then the graphic is displayed behind the text. $oJson.UpdateString("appearance.imagePlacement","left") ; The graphic's opacity can range from 1 to 100. ; Centered graphics look best with less opacity (50 or less). ; In this example, we'll keep the opacity at 100. $oJson.UpdateString("appearance.imageOpacity","100") ; Here's an example of the signature's appearance if we centered the SVG graphic with an opacity of 40% ; Load the signing certificate. (Use your own certificate.) $oCert = ObjCreate("Chilkat.Cert") $bSuccess = $oCert.LoadPfxFile("qa_data/pfx/myPdfSigningCert.pfx","secret") If ($bSuccess = False) Then ConsoleWrite($oCert.LastErrorText & @CRLF) Exit EndIf ; Tell the pdf object to use the certificate for signing. $bSuccess = $oPdf.SetSigningCert($oCert) If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf $bSuccess = $oPdf.SignPdf($oJson,"qa_output/hello_signed.pdf") If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf ConsoleWrite("The PDF has been successfully cryptographically signed." & @CRLF) ; The appearance of the signature appears in Adobe Acrobat as shown here: ; The SVG icon graphics are embedded within the Chilkat library, ; and were graciously provided by uxwing - Free SVG Icons ; ; The uxwing licensing terms are reproduced here and can be verified at uxwing licensing ; Icons from uxwing.com are free (see https://uxwing.com/license/) ; - All icons on UXWing free to download, and use personal, commercial projects. ; - Attribution and Credit is NOT required, however, any credit will be much appreciated. ; - There is no limit to the number of times you can use. ; - You may modify the resources according to your requirements. ; The set of SVG names and the corresponding graphics are shown below. ; ; For example, if we specify "green-check-green-circle" $oJson.UpdateString("appearance.image","green-check-green-circle") ; We get: ; "application-approved" ; "application-rejected" ; "document-accepted" ; "approved" ; "blue-check-mark" ; "green-check-mark" ; "green-check-grey-circle" ; "red-x-red-circle" ; "rejected" ; "result-failure" ; "result-pass" ; "signature" ; "document-check" ; "document-x" ; "red-x-grey-circle" |
