Digital Sig placed fails on color document

Post by prime clinical systems » Wed May 01, 2019 3:57 am

Hi, this code for digital signature from my other post works fine if document is black and white or grey scale, but not color, I attached a sample page and need to see what can be done to get this to work on that document. I notice if after signing with this code the signatures pane says the signature exists, but is not visible.

Dim nID As Long
Dim Op As PDFXEditCtl.IOperation
nID = Me.PDF.Inst.Str2ID("op.document.addDigitalSignature")
Set Op = Me.PDF.Inst.CreateOp(nID)
Dim Options As PDFXEditCtl.CoAUX_Cab
Dim Input1 As PDFXEditCtl.CoAUX_Cab
Set Input1 = Op.Params.Root("Input")
Dim Doc As PDFXEditCtl.IPXC_Document
Set Doc = Me.PDF.Doc.CoreDoc
Input1.Add().v = Doc

Set Options = Op.Params.Root("Options")
Options("FieldName").v = FField.FullName
Options("DocMDP").v = 3
Options("DigiSigType").v = 1
Options("FileCertificate").v = "C:\Users\username\username & ".pfx"
Options("UseFileCertificate").v = True
Options("CertificatePassword").v = "abcdefg"
Options("AskDestinationFileName").v = False
Options("DestinationFileName").v = SourceDocPath
Dim appear As CoAUX_Cab
Set appear = Options("SignatureAppearance")
appear("HasTemplate").v = True
Dim Temp As CoAUX_Cab
Set Temp = appear("Template")
Temp("GraphicType").v = 2
Temp("GraphicName").v = SigPath
Temp("TextDirection").v = 0
Temp("ShowName").v = True
Temp("ShowDate").v = True
Temp("ShowLabels").v = True
Temp("ShowLogo").v = True
Op.Do

Hello prime clinical systems,

Have you tried signing that document manually via the End-User Editor?

Cheers,
Alex

Hi Alex, please this has to work in code, the above works fine on monochrome and grey-scale, so please investigate, thanks
attached the same document converted to b/w and greyscale so you can see the issue.

Hello prime clinical systems,

That's not the case - there is no point of trying that via code when this does not work like intended in the End-User Editor. That's why I asked you to check this scenario manually and see whether the problem persists. If not - then we can take a deeper look into the code and why it's happening. If the problem does reoccur in the End-User Editor, then we'll forward this to the appropriate developer and this will be fixed from our side.

Cheers,
Alex

Problem is Alex you can't replicate the actions of the code in the end user editor, as in editor you are first physically placing a signature box and pops up UI to select certificate etc, and in that case it does work, but does NOT work in code. I will pay extra to have someone test this if need be, just tell me how. Thanks

I also tried this method
Call Me.PDF.Doc.CoreDoc.AcroForm.Document.DeferedDigitalSignFieldPFX("C:\Users\Public\" & Userinit & "\" & Userinit & ".pfx", Password, FField, Sign_GR_Image, "Approve", "Work", Phone, TempSigPath)

Works on b/w and greyscale, does not work on color either.

Hello prime clinical systems,

Tomorrow I will be at work so I will try to look at the problem and will tell you the results of the investigation.

Cheers,
Alex

Re: Digital Sig placed fails on color document  SOLVED

Hello prime clinical systems,

Just tested the behavior - signed all of the files with or without FieldName specified by using your code in FullDemo application. Everything worked correctly.
Here's the code that you can try for yourself:

Code: Select all

int nID = pdfCtl.Inst.Str2ID("op.document.addDigitalSignature", false);
PDFXEdit.IOperation Op = pdfCtl.Inst.CreateOp(nID);
PDFXEdit.ICabNode input = Op.Params.Root["Input"];
input.Add().v = pdfCtl.Doc;
PDFXEdit.ICabNode options = Op.Params.Root["Options"];
options["FieldName"].v = "Signature1"; //this can be commented so that the signature will be added on the page itself
options["DocMDP"].v = 3;
options["DigiSigType"].v = 1;
options["FileCertificate"].v = @"D:\111111.pfx";
options["UseFileCertificate"].v = true;
options["CertificatePassword"].v = "111111";
options["AskDestinationFileName"].v = false;
options["DestinationFileName"].v = @"F:\testcolor_signed.pdf";
PDFXEdit.ICabNode appear = options["SignatureAppearance"];
appear["HasTemplate"].v = true;
PDFXEdit.ICabNode tmplt = appear["Template"];
tmplt["GraphicType"].v = 2;
tmplt["GraphicName"].v = @"D:\sig.bmp";
tmplt["TextDirection"].v = 0;
tmplt["ShowName"].v = true;
tmplt["ShowDate"].v = true;
tmplt["ShowLabels"].v = true;
tmplt["ShowLogo"].v = true;
Op.Do();
PDFXEdit.IPXC_Document doc = (PDFXEdit.IPXC_Document)Op.Params.Root["Output"][0].v;
pdfCtl.OpenDocFrom(doc);
Maybe the size of the field that you have specified is too small to see the signature?

Cheers,
Alex

ok thanks for trying, just does not work, must be vb6 isssue, one thing I noticed is that their is no defined colorspace for the page, and when I try other color documents that do have a colorspace, it does work. Seems its the html to pdf convertor I use to create the page I sent you that does not define the colorspace for the page that is the issue.

Hello prime clinical systems,

Well, sadly, we can't do much here from our side.

Cheers,
Alex
