I use HTML2PDF tool to export my HTMLs to PDFs. It's a great tool !
However, I am having difficulties implementing Digital Signature Form Field for PDFs !
Basically, what I want, is to add the posibility for digital signing with one click by the client !
(I don't want to digitally sign the PDF with the server's key ! This PDF is downloaded by my clients and each of them must sign with its own digital signature).
Other PDF documents (probably created with other software) have the possibility of inserting a form field for signatures (like textbox, checkbox, radio button, etc.), that when the user clicks it, it automatically asks for the client's Digital Client Certificate (and the user Inserts its Cryptographic Token into the computer and can digitally sign the respective PDF).
How can I generate (I don't know, on the HTML side or on the PHP or PDF side) the necessary form field that when I export my PDF and download it, after opening it with Adobe Reader, for example, clicking on the respective field, the system having to ask me about my digital signature ?
I can always download the PDF manually and use Adobe Reader to Sign the PDF, but I saw other PDFs with forms built-in to digitally sign a document...
Or any other solution would be great...
Thank you !
Trying to digitally sign a PDF document locally by using a form field which I click and it directly asks me for to sign the document.
I cannot generate this kind of a PDF on the server side using PHP and HTML2PDF.
I might be able to do this from Adobe Acrobat Pro, for example, but the PDF is generated automatically on the Web Server.
In my app I am able to sign some pdf.
Actually, after that the customer signed the document, we tap on the pdf where we wants to place the signature.
But we have to change this, because when we have a 30 pages pdf and the signature is at the end, we have to scroll so much.
So, we decided to add an input "signature" in the pdf, so the app could find this input and fill it with the signature, with the x and y position.
But how can I fill a PDF input with my image ?
We sign PDF documents by ELDOS.SecureBlackBox library which can place visible signature everywhere in document, but if we generate PDF dynamically by HtmlToPdf, right place for visible signature is various. This problem can be solved by adding signature field to PDF document and SecureBlackBox shows signature on this place. But the question is, how can I add a signature field with HtmlToPdf.
I am using FOP to generate the PDF from XSL:FO and iText to apply the digital signature and signed date field in the PDF.
Problem is i am using co ordinates to apply the signature and date in the generated PDF.
The PDF are large, dynamic and changing always based on content. therefore the signature and date fields were not positioned Properly by the co-ordinates specified.
I googled to find solution for a long days. But i didnt get any solutions.
Can u please any one suggest me to create the PDF form fields in the PDF using FOP?
Then i can apply signature and date fields by using iText.
Please tell me any other technology to try to solve this problem?
The problem is that FOP doesn't create signature fields whereas iText needs a page number and coordinates (either defined by you or by a signature field).
Where do you want the signature to be placed?
Is it always on the first page? Always on the last page?
Can you put some unique text at the location where you want the document to be signed?
I'm asking this because you could put words like SIGN HERE on the last page, and then use TextRenderInfo to retrieve the coordinates of those words. See http://itextpdf.com/examples/iia.php?id=275 in combination with http://itextpdf.com/examples/iia.php?id=282
The TextRenderInfo class has methods such as getBaseLine(), getDescentLine(),... who give you LineSegment object which reveal the coordinates of each snippet of text in your PDF.
There are plenty of caveats: FOP could cut the words SIGN HERE in different snippets, such as "SIG", "N", "HE", "RE" which would make it difficult to recognize the unique string, but it's worth investigating.
I receive around 30 workorders a day from my primary client. They send them to me in a standardized report format, in a single PDF, with one page for each different workorder. Unfortunately, these PDF reports dont include the workrorder_ID in a barcoded format, only in regular text font and they are unwilling to comply to my request to modify the report by adding a barcode. Is there a way to automatically add a barcode to the PDF? basically I would want the PDF editing app to search for the text “workoder ID:” and to insert the barcode, beneath the work_order ID.
please advise. thanks very much
You will need to use a PDF Library that includes a text extraction that includes reporting the location of each string extracted. When you find the location of the Work Order ID text you can then use the same library add the barcode in correct position. Quick PDF Library would be one option and iText be another.
