How to extract text from a PDF file?

Hello Suners,
i need to know how to extract text from a pdf file?
does anyone know what is the character encoding in pdf file, when i use an input stream to read the file it gives encrypted characters not the original text in the file.
is there any procedures i should do while reading a pdf file,
File f=new File("D:/File.pdf");
               FileReader fr=new FileReader(f);
               BufferedReader br=new BufferedReader(fr);
               String s=br.readLine();any help will be deeply appreciated.

First, you set i once, and then loop without ever changing it. So your loop body will execute either 0 times or infinitely many times, writing the same byte every time. Actually, maybe it'll execute once and then throw an ArrayIndexOutOfBoundsException. That's basic java looping, and you're going to need a firm grip on that before you try to do anything as advanced as PDF reading. the case.oops you are absolutely right that was a silly mistake to forget that,
Second, what do the docs for getPageContent say? Do they say that it simply gives you the text on the page as if the thing were a simple text doc? I'd be surprised if that's the case.getPageContent return array of bytes so the question will be:
how to get text from this array? i was thinking of :
    private void jButton1_actionPerformed(ActionEvent e) {
        PdfReader read;
        StringBuffer buff=new StringBuffer();
        try {
            read = new PdfReader("d:/getjobid2727.pdf");
            read.getMetaData();
            byte[] data=read.getPageContent(1);
            int i=0;
            while(i>-1){
                buff.append(data);
i++;
String str=buff.toString();
FileOutputStream fos = new FileOutputStream("D:/test.txt");
Writer out = new OutputStreamWriter(fos, "UTF8");
out.write(str);
out.close();
read.close();
} catch (Exception f) {
f.printStackTrace();
"D:/test.txt" hasn't been created!! when i ran the program,
is my steps right?

Figuring out how to extract images from a PDF file

Hi,
I'm trying to write a small app that extracts all images from a PDF file. I already wrote a nice parser and it works good but the only problem is that I can't quite figure out from the reference how to decode all images in a PDF file to normal files such as tiffs, jpegs, bmps etc. For now I'm focusing on XObject images and not dealing with inline images.
From what I understand so far just by trying and looking at open sources I figured that if I see a XObject Image with a DCTDecode filter, taking the stream data without doing anything to it and saving it as a jpeg file works. But doing the same to FlateDecoded streams or CCITTFax didn't work.
What is the right way to properly extract the images?

In general you have to
* decode the stream
* extract the pixel data
* use ColorSpace, BitsPerComponent, Decode and Width to unpack pixel
values
* reconstruct an image file format according to its specification
There are no other shortcuts. The DCTDecode shortcut (which doesn't
work for CMYK JPEG files) is just a piece of fantastic good luck.

How to extract data from offline PDF files as batch processing

Hello.
I want to use Adobe Interactive forms as batch processing.
For instances,
1. Users download offline PDF files.
2. Users inputs data on their local PCs.
3. Users upload these PDF files in one folder.
4. Program can read data form PDF files on that folder. and put data to ERP at night.
I' d like to know how to implement a program with Java or ABAP.
Regards.
Koji.

Hi,
It's possible to do it but first be sure that the SAP system can read the directory while your program is executed in background .
Then you have to read the content of the directory and process each file you found.
Look at this standard ABAP object cl_gui_frontend_services , you will find method for browsing a directory and retrieve list of file .
Afterwards you have to process each file , for this have a look at this wiki code sample i wrote for processing inbound mail with adobe interactive form, it should help you [Sample Code for processing Inbound Mail with Adobe Interactive Forms|https://www.sdn.sap.com/irj/sdn/wiki?path=/display/snippets/sampleCodeforprocessingInboundMailwithAdobeInteractive+Forms]
Hope this help you .
Best regards.

How to add text to a pdf file using Access VBA??

I'm down on my hands and knees, begging. I have 300 files that I want to put a variable string at the top of the first page (centered, or at the right hand side). I am using Acrobat X and Microsoft Access 2010 and I do have the SDK and have spend over 10 hours so far searching it and the internet in general, for help and still am coming up empty handed.
I can do the looping and passing variables with my eyes closed, but I cannot get the syntax for the actual opening of the pdf and inserting the string.
I was trying to modify code I found yesterday that is supposed to add an annotation, but I don't want an annotation, I just want a string of text at the top of page 1. For now, all I want is to be successful at doing ONE file. Can someone please give me a concrete example of the code I need to use? Like I said, I'm in begging mode
Public Sub AddText()
    Dim pdDoc As Acrobat.AcroPDDoc
    Dim page As Acrobat.AcroPDPage
    Dim annot As Acrobat.AcroPDAnnot
    Dim jso As Object
    Dim strPath As String
    Dim intpoint(1) As Integer
    Dim intpopupRect(3) As Integer
    Dim props As Object
    Set pdDoc = CreateObject("AcroExch.PDDoc")
    pdDoc.Open ("c:\Test\Test.pdf")
    Set page = pdDoc.AcquirePage(0)
    'Set annot = page.AddAnnot(0)
    intpoint(0) = 0
    intpoint(1) = page.GetSize.y
    intpopupRect(0) = 0
    intpopupRect(1) = page.GetSize.y - 100
    intpopupRect(2) = 200
    intpopupRect(3) = page.GetSize.y
    annot.SetColor (vbRed)
    annot.SetContents "JCPC - 22 - 2011050000001"
    pdDoc.Save 1, "c:\Test\Test.pdf"
    pdDoc.Close
    Set pdDoc = Nothing
    MsgBox "Done"
End Sub

You cannot skip arguments, you can either use the function with one
argument (just the required argument), or you have to provide all of them.
Also, it looks like you are trying to specify 20 parameters, even though
the function only takes 19. Try the following:
Call jso.addWaterMarkFromText("Test Text", jso.app.Constants.Align.Center,
jso.Font.Helv, 16, _
    jso.Color.Black, 0, 0, True, True, True, _
    jso.app.Constants.Align.Center, jso.app.Constants.Align.Center, _
    100, 100, False, 1, False, 0, 1)
I just typed this in without running it through the compiler, so there may
be typos in the code, but you should get the idea of how the code is
supposed to look like.

Hello pf1tarac, I don't believe that is possible. In order to create a PDF file, you would need Adobe Acrobat or some other PDF compatible product to save a scan to the PDF format.
There are some free PDF programs available. Here is a link to one of them.

Using browser javascript to copy selected text from a pdf file opened in Air app.

I have posted this question on reader forum as well, but I think it is more suited here...
I am trying to create a note-taking application in air. I want to extract selected text from pdf file as a string object or to the clipboard.
Obviously, all pdfs in my local storage will not be scripted to recieve postMessages and act accordingly, and that is not practical either. So, my problem is, how can I copy the selected text in the pdf file (opened as an object in htmlloader within my Air app) to clipboard or directly in another control by say clicking a button in air application? I suppose, this is possible using javascript, however, I don't know which reader methods are exposed to the wrapper htmlloader control. In short, I want to execute app.execMenuItem("Copy") command through htmlloader javascript. Any alternate solutions are also welcome.
This is similar to passing inbuilt commands/methods/functions (of adobe reader) to pdf-reader plugin embedded in a webpage via javascript. This is possible in IE where the pdf is rendered as activex object, and hence JSObject interface of pdf document/reader is accessible to the browser javascript. I have also read that this same JSObject is accessible to VB as interface for IAC, so as the Air is Adobe's own product, I was wondering if equivalent of JSObject is accessible to htmlloader control as well.
Thanks in advance...
Mits

Thank you Thom for your reply...
from
http://www.adobe.com/devnet/acrobat/javascript.html
...Through JavaScript extensions, the viewer application and its plug-ins expose much of their functionality to document authors, form designers, and plug-in developers...
As it is explicitly mentioned, that the functionality of adobe reader are exposed for plugin development, I thought someone here might have used external javascript to execute some safe methods in adobe reader. The functionality (i.e. external javascript interface-JSObject) is already available for VB programmers to develop IAC. Further, the Acrobat SDK example called "AcroPDFinHML" shows how one can embed a pdf-reader in a html page and execute some safe methods (like gotonextpage(), zooming etc.) in IE as ActiveX plugin. I have checked it myself for adobe reader 9, and it works perfectly, so there is no security issue as such to implement the same for another browser (like in my case, the htmlloader control in flex/air app).
I intend to create a note taking application in air, where it is very much required that I should be able to copy selected text from various pdf documents, that are open in my app, and subsequently paste/collect/save the collected notes and process them afterwords (offcourse, from the pdfs that allow me copying text). However, it is not happening for me here. As the pdfs are opened through adobe reader plugin, it does not register the copy command executed by my air app. It registers the system level copy command (by keyboard shortcut Ctrl+C), but my air app has no way to execute the system level copy command programmatically. So I am kind of stuck here...
Thanks again for your reply. Having known what am I intend to accomplish, any other (may be alternative) solutions will be appreciated nonetheless...

Why cannot I copy selected text from a pdf file opened in Adobe Reader XI?

Hi all,
I had a problem when I tried to copy some selected text on a pdf file([Linux.System.Programming(2nd,2013.5)].Robert.Love.文字版.pdf) , which was opened in Adobe Reader XI as below (non-English version):
The error's text could be primarily translated as "An error occured when copied to clipboard. Internal Error." I'm not sure about the reason of this. I guess it is a problem or bug related to operating system or Adobe Reader XI. I had this problem when I used other versions of Adobe Reader though I cannot remember the exact number of versions now.
The version of XI I'm using is 11.0.0. The operating system is XP SP3.
As I was writing this question, the problem disappeared and I cannot reproduce it again now.
Could anyone help explain why the error message appearred or why the problem disappearred? If there is referrence provided, that would be finer. Thank you.

How to retrieve IndividualStrings from a txt file using String Tokenizer.

hello can any one help me to retrieve the individual strings from a txt file using string tokenizer or some thing like that.
the data in my txt file looks like this way.
Data1;
abc; cder; efu; frg;
abc1; cder2; efu3; frg4;
Data2
sdfabc; sdfcder; hvhefu; fgfrg;
uhfhabc; gffjcder; yugefu; hhfufrg;
Data3
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
i need to read the data as an individual strings and i need to pass those values to diffarent labels,the dat in Data3 i have to read those values and add to an table datamodel as 6 columns and rows depends on the data.
i try to retrieve data using buffered reader and inputstream reader,but only the way i am retrieving data as an big string of entire line ,i tried with stringtokenizer but some how i was failed to retrive the data in a way i want,any help would be appreciated.
Regards,

Hmmm... looks like the file format isn't even very consistent... why the semicolon after Data1 but not after Data2 or Data3??
Your algorithm is reading character-by-character, and most of the time it's easier to let a StringTokenizer or StreamTokenizer do the work of lexical analysis and let you focus on the parsing.
I am also going to assume your format is very rigid. E.g. section Data1 will ALWAYS come before section Data2, which will come before section Data3, etc... and you might even make the assumption there can never be a Data4, 5, 6, etc... (this is why its nice to have some exact specification, like a grammar, so you know exactly what is and is not allowed.) I will also assume that the section names will always be the same, namely "DataX" where X is a decimal digit.
I tend to like to use StreamTokenizer for this sort of thing, but the additional power and flexibility it gives comes at the price of a steeper learning curve (and it's a little buggy too). So I will ignore this class and focus on StringTokenizer.
I would suggest something like this general framework:
//make a BufferedReader up here...
do
String line = myBufferedReader.readLine();
if (line!=null && line.trim().length()>0)
line = line.trim();
//do some processing on the line
while (line!=null);So what processing to do inside the if statement?
Well, you can recognize the DataX lines easily enough - just do something like a line.startsWith("Data") and check that the last char is a digit... you can even ignore the digit if you know the sections come in a certain order (simplifying assumptions can simplify the code).
Once you figure out which section you're in, you can parse the succeeding lines appropriately. You might instantiate a StringTokenizer, i.e. StringTokenizer strtok = new StringTokenizer(line, ";, "); and then read out the tokens into some Collection, based on the section #. E.g.
strtok = new StringTokenizer(line, ";, ");
if (sectionNo==0)
//read the tokens into the Labels1 collection
else if (sectionNo==1)
//read the tokens into the Labels2 collection
else //sectionNo must be 2
//create a new line in your table model and populate it with the token values...
}I don't think the delimiters are necessary if you are using end-of-line's as delimiters (which is implicit in the fact that you are reading the text out line-by-line). So the original file format you listed looks fine (except you might want to get rid of that rogue semicolon).
Good luck.

How do I copy and paste text from a pdf file and paste it into a new pdf or word file?

I have a very large pdf file (500 pages) comprised of 200 letters. How do I copy individual letters (copy and paste sections of the file) and put them in a new pdf or word file?
Thank you

Hi drredwood,
When you open your PDF file a yellow bar will appear on the top of the screen.
Click on 'Enable All Features'.
Then you will be able to copy the content from your pdf and to paste in any of the file.

How does full-text search for pdf files work?

Hi there,
Basically I can see my pdf file in the content server.. inside the pdf there's a piece of test that says: "Test's Sample" but when I do a search with that string the file gets filtered from the results.
I think it has to do with the ' (single quote) being there because other text in the pdf works fine.. so I was wondering how does VDK store this full text? where? I'd like to see how it gets translated IF that's how it works with pdf files....
Following advice from Re: Parse error with search query I tried doing the search by:
Test\'s Sample
Test`s Sample
"Test's Sample"
The database is db2 if that helps.. how can I fix this problem?

Nevermind, I fixed it by changing the VDK filters (in case someone is looking for a solution too).
Cheers,
