Extract name from pdf digital signature

I'm looking for info on extracting the digital signature name from a digitally signed field already in the pdf. I can see the signature when I open the file in Adobe Reader, but when I read the fields using cfpdfform, the digital signature field and its info is not listed amoung the fields.
What procedure piece am I missing?

Hi all,
i have the same problem. Is it possible that only we have this problem? I found solutions with external partners, but i think it should be possible to do it inside SAP R/3, isn't it?
best regards
Erwin

Applescript or workflow to extract text from PDF and rename PDF with the results

Hi Everyone,
I get supplied hundreds of PDFs which each contain a stock code, but the PDFs themselves are not named consistantly, or they are supplied as multi-page PDFs.
What I need to do is name each PDF with the code which is in the text on the PDF.
It would work like this in an ideal world:
1. Split PDF into single pages
2. Extract text from PDF
3. Rename PDF using the extracted text
I'm struggling with part 3!
I can get a textfile with just the code (using a call to BBEDIT I'm extracting the code)
I did think about using a variable for the name, but the rename functions doesn't let me use variables.

Hello
You may also try the following applescript script, which is a wrapper of rubycocoa script. It will ask you choose source pdf files and destination directory. Then it will scan text of each page of pdf files for the predefined pattern and save the page as new pdf file with the name as extracted by the pattern in the destination directory. Those pages which do not contain string matching the pattern are ignored. (Ignored pages, if any, are reported in the result of script.)
Currently the regex pattern is set to:
/HB-.._[0-9]{6}/
which means HB- followed by two characters and _ and 6 digits.
Minimally tested under 10.6.8.
Hope this may help,

Extract Text from pdf using C#

Hi,
We are Solution developer using Acrobat,as we have reuirement of extracting text from pdf using C# we have downloaded adobe sdk and installed. We have found only four exmaples in C# and those are used only for viewing pdf in windows application. Can you please guide us how to extract text from pdf using SDK in C#.
Thanks you for your help.
Regards
kiranmai

Okay so I went ahead and actually added the text extraction functionality to my own C# application, since this was a requested feature by the client anyhow, which originally we were told to bypass if it wasn't "cut and dry", but it wasn't bad so I went ahead and gave the client the text extraction that they wanted. Decided I'd post the source code here for you. This returns the text from the entire document as a string.
       private static string GetText(AcroPDDoc pdDoc)
            AcroPDPage page;
            int pages = pdDoc.GetNumPages();
            string pageText = "";
            for (int i = 0; i < pages; i++)
                page = (AcroPDPage)pdDoc.AcquirePage(i);
                object jso, jsNumWords, jsWord;
                List<string> words = new List<string>();
                try
                    jso = pdDoc.GetJSObject();
                    if (jso != null)
                        object[] args = new object[] { i };
                        jsNumWords = jso.GetType().InvokeMember("getPageNumWords", BindingFlags.InvokeMethod, null, jso, args, null);
                        int numWords = Int32.Parse(jsNumWords.ToString());
                        for (int j = 0; j <= numWords; j++)
                            object[] argsj = new object[] { i, j, false };
                            jsWord = jso.GetType().InvokeMember("getPageNthWord", BindingFlags.InvokeMethod, null, jso, argsj, null);
                            words.Add((string)jsWord);
                    foreach (string word in words)
                        pageText += word;
                catch
            return pageText;

Extracting images from pdf

I am trying to extract images from pdfs using pdfimages, but i am unable to retrieve all the images. By opening the pdfs using Acrobat Reader 9.0, I am able to select, those images retrieved by pdfimages, using the select tool but for other figures/images we need to try other options like print screen and then cut the relevant image. I was wondering why or when does the Acrobat treats the figures/images differently.

Hi Dave,
Thanks for the reply. My question was not regarding any non-Adobe product like pdfimages. It was in general the way Acrobat handles the images while creating pdfs.
I wanted to know why can we select some of the images from the pdf using select tool and can not select others for which we need to print screen and cut. Is there anything in the eps files of included image that causes such effect?
Thanks.

Extracting Images from PDF file

I think you can do it through cos object in VC++ plugin..go through the PDEFilterSpec in
Acrobat core api reference
Be well..

PDF digital signature SDK

We are software house in document management are, and we want incorporate in our document management solution the feature of PDF digital signature.
What is your best SDK product for doing this (PDF Library SDK or Acrobat SDK)?
We have a windows client developed in C++ unmanaged and a web client developed in C#.
And what is the price of the product?
The price includes royalty free when delivered integrated with our product?
Thanks & Regards,
Rui Oliveira

It is to be delivered integrated with our software that it is installed in multiple servers and with multiple web/windows computers doing digital signatures.
The windows client is developed in C++ unmanaged and the web client developed in C#.
In first stage, could be enough to integrate with our windows version (developed in C++ unmanaged). This is a thick windows client installed in each client computer (Acrobat Pro is not installed in each client computer).

Process to extract comments from PDF

Greetings,
I need to extract comments from PDF during a process workflow. Will exporting metadata alone work? If not, could someone please point me in the right direction?
I'm not enitrely sure where the comments reside (written, sticky notes, stamps, etc.).
Thanks in advance,
Alex

I don't think the meta-data will give you th annotations layer of the PDF. You'll probably need to use Assembler's invokeDDX service to export the comments into a n XFDF file (an XML representation of the comments)
The instructions should be in the DDX Reference:
http://help.adobe.com/en_US/livecycle/9.0/ddxRef.pdf
something like:
<Comments result="doc1comments.xfdf" format="XFDF">
<PDF source="doc1.pdf"/>
</Comments>

How do I write javascript for a text block to extract name from signature block?

Hello,
I've created a training certificate that the trainee has to sign electronically. To prevent someone from simply putting in their friends name in there and saving it; to send to their friend and help them from having to take the training and quiz I would like to write a javascript in the text block that would extract the name from their signature block and autofill the name in the text block. Is there a way to do this?

You would have to use JavaScript to access the signature field object and then you can access the various properties of the signature depending upon the certificate or method for signing.
signatureInfo
console.show();console.clear();
// Get particular info;
var f = this.getField("Signature1");
// uses the ppklite sig handler;
var Info = f.signatureInfo();
// Some standard signatureInfo properties;
console.println("name = " + Info.name);

Extract Attachment from Pdf

I want to extract the files attached with pdf.I am using Assembler 7.2 . The DDX for extract is given below
It returns the xml file with attachment file datastreams name. How can i identify that file is of what type?
how to store that data stream ?

As Don pointed out, you can parse the result XML which contains information about each extracted file attachment, including the unique name created for the document, the filename that was originally associated with the document, and the content type, if it was originally provided.
The problem with using the filename for the extracted name of the document in the AssemblerResult documents map is that the filename is not guaranteed to be unique.
You can ask for the result XML without actually extracting the file attachments (extract="false"), and then use the information from the result XML to get exactly the file attachments you want.
The unique name created (the attachmentKey) actually provides information as to whether the file attachment was attached to the document in general or to a specific page, such as for a comment annotation.
The attachments.xsd schema is installed in the LC ES SDK to assist with parsing.
Here's an example result XML with one document-level and one page-level file attachment:
<?xml version="1.0" encoding="UTF-8"?>
<Attachments xmlns="http://ns.adobe.com/DDX/Attachments/1.0/">
<Attachment attachmentKey="doc.source_attach.0000.0001" name="Untitled Object">
<File creationDate="2004-08-05T01:34:18Z" mimeType="image/jpeg" modificationDate="2000-03-30T01:46:42Z" size="14359">
<Filename fromEncoding="ISO-8859-1" success="true">Origami.jpg</Filename>
</File>
<Description>This is Origami.jpg, a document-level attachment.</Description>
</Attachment>
<Attachment attachmentKey="doc.source_attach.0003.0001">
<File creationDate="2004-08-05T01:34:16Z" mimeType="image/gif" modificationDate="2002-09-10T01:51:22Z" size="3939">
<Filename fromEncoding="ISO-8859-1" success="true">dog.gif</Filename>
</File>

How do I switch from a digital signature back to an "ink" signature

Reader 11.0.10
Had a doc that required a certificate signature, so I created and used one.
Now I want to go back to using my "ink" signature... how do I do that?
(In a fresh document, if I clock on "Place Signature" button it begins the digital process)

I am in the process of updating all of my organization's PDF forms and creating an environment to digitally share them. The problem that I am running into is these forms have been created by many people by various means. I have found that some forms, when opened with Adobe Reader XI, will not allow me to place a digital signature - neither drawn or with a certificate. Some forms will let me use a digital certificate but not a drawing. I have no idea what settings are different across these different forms that would cause what seems to be different permission levels for different forms.
This is also present when I'm using iOS Adobe Reader - on some forms the signature pen tool is available and on others it isn't. On the ones that it isn't, I can still use the freehand draw tool, but that doesn't work as well as the signature tool.
All of these forms are fillable and savable. Thoughts?

Extract text from pdf

Hi, is it possible to extract text from a pdf file using the command line to get an output like you would get by using the File menu and then 'Save as text..."?
I also noticed that in the installation folder there is a small executable called AcroTextExtractor which sounds interesting, but I was unable to figure out how to use it.

what's wrong with using automator for this? this certainly seems the easiest. I'm not aware of any built in apple script commands that will do this. But You should also ask on the Apple script forum under Mac OS Technologies.

Extracting XML from Pdf form

There is an industry standard pdf form with an underlying XML schema which can be opened in Adobe reader.
The form has a custom button on Page 2 called "export" which can be manually clicked to export the XML file.
We will have hundreds of these forms. How would I automate the extraction of this XML document?
I would prefer to just write a simple script and extract out the xml to a file folder
Thanks for your help.

Thanks Patrick.
We are thinking about using a third party native Java library to do this (http://www.qoppa.com/pdffields/jpfindex.html). I was hoping we could use acrobat reader, since everyone has it!
Here are a few more things.
1. We are an Software Vendor that sells our solutions - our software solutions need to extract the xml from pdf. We have a java based program that parses this xml and does stuff with it.
2. Obviously, we would need to be able to redistribute whatever solution we use to extract the xml from pdf.
3. Can Acrobat Professional batch mode be executed from Java?
4.. If so, Instead of distributing a full blown Acrobat Professional or requiring customers to buy it, is there a library that Adobe provides that we could repackage and ewdistribute? If so, can you send me some pointers on where I could find what those libraries would be and how much would they cost for each distribution we do.
5. If no, are you familiar with qoppa or do you have recommendations on any other third party libary for Java?
Thanks a bunch!
