Thank you for information. Is there any way to remove signature from file before new signing, to prevent such situation ?

Stefan, I have not used the incremental saving. Sequence went as follows:
1. Open PDF
2. Sign with PXCp_SignDocumentUsingPFXW
3. Save file with PXCp_WriteDocumentW
then:
4. Open PDF
5. Add text and image watermark
6. Sign with PXCp_SignDocumentUsingPFXW
7. Save file with PXCp_WriteDocumentW

Hello, I have signed the PDF with your component, and saved it. Then I opened it, added some text, signed and saved. So I have PDF with two signatures. Adobe Reader shows both signatures, says the first one have technical problem with byte range, and gives no chance to show version signed with first...

Is it possible to extract/change the XML file from that XFA form with your component (ie. running some JavaScript or any other way) ?
What time do you plan to make next major version ?

Thank you for answer.

Hello,
could you please look at the file attached and tell me why it is not displayed correctly in your Viewer component ? File has 3 pages of form with lot of fields, but in your Viewer, only one page with informational text (about upgrading Acrobat) is displayed.

I need to make signatures which are not visible on any document page. Presence of such a signature in Adobe Reader is noticeable only in "signatures panel". I have attached the sample project which signes PDF document with Sign_GR_NoGraphics option. As you can see in output file signed.pdf...

In attached archive, you see the test project, input file (test.pdf) and output file (testWater.pdf). Please note that output file testWater.pdf contains eight embedded subsets of ArialMT font.

Thank you for making it clear. :D I have another issue. When I add 4 lines of text into watermark, every line embeds its own subset of used font into resulting PDF. When I try to set embedding with PXC_SetEmbeddingOptions and PXC_SetFontEmbeddA functions, I receive an Error: PdfLib [Operation/Featur...

Hello,
I am trying to generate PDF without most common fonts embedded but I am not successful. Plees see my source .doc, resulting .PDF and test project in VB 6.

Thank you for your reply.

When I place some image into watermark, does it get compresed or optimized ? Does it get rescaled when I set smaller width and height than input image is ?

My code is very simple, it does the following: 1. InitPXCp 2. Open existing PDF using PXCpVB_ReadDocumentW 3. res = PXCpVB_SignDocumentUsingPFXW(hPDF, CertPath, CertPass, 0, rect, "", " ", "", "", Sign_GR_NoGraphics) 4. Save file using PXCpVB_WriteDocumentW an...

Hello, which types of image can I use as watermarks ?

Hello,
I am trying to digitally sign the PDF document without the graphic portion of signature, but the graphics is still present, even when I specify the Sign_GR_NoGraphics option. I am doing something wrong or is it the bug ?

Hello Stefan, did you get an answer for the question above ?

Hello,
When I make signed PDF, am I able to detect whether the signing proces was succesfull and the resulting PDF is signed ?

The password entry dialog should be displayed by the layer which computes the signature. To incorporate this feature into the program may be possible, but it's another story.

Hello Corwin We have not seen any certificate installed in system which was password protected. Are you sure that system storage allows doing such things? Yes, it allows. When you import the certificate with private key from .pfx file into your storage, you can set the private key security to high a...

Corwin, thank you very much, it worked. I wonder why the line .Option("DigiSig.PFXPath") = "c:\pokus2.pfx" does not throw exception. Would it be possible to incorporate some verification of input values into next build of your product ? For example it may throw exception in the c...

Hello, I have installed current demo release of PDF-XChange Drivers. When I set digital signature properties (certifacate etc.) manually in printer options, and then print anything, everything works fine an I get signed PDF file. But when I try to do the same things programmatically, no error is dis...
