Cannot see text in large PDF file

Hi all,
I've searched Google and these forums, but I have yet to find anything relating to my issue.
I'm trying to view a PDF file, but I cannot see any text in Adobe Reader.
I've viewed it w/ the FoxIt reader, and I can see all text there.
Any idea as to what the problem w/ Adobe reader is?
I have the most up-to-date version of the reader.
Thanks in advance.

Enable the entry 'Show large images' in the preferences of Adobe Reader.

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.

There is a program from Wondershare, called PDF Password remover, that will remove such restrictions, but I'm not allowed to recommend it, only to point out it's existence.

Cannot Open Large PDF file 100 mb

Cannot open a 118 Mb pdf file. Adobe Reader 11 opens, no error messages, does not show the file. I downloaded the file from three different sources.
Is there a utility that I can use to check the validity of the pdf file?
tony-only

Reader is a pretty good tool, but it isn't designed to check validity specifically; then again, nor is anything else.
Can you share the URL of the file?

Full text search of .pdf files in a file table.

I have installed the Adobe iFilter 11 64 bit and set the path to the bin folder. I still cannot find any text from the pdf files. I suspect I am missing something trivial because I don't find much when I Bing for this so it must not be a common problem.
Here is the code.

Hello,
We believe we have figured this out. It looks like it has to do with the length of the default folder location for the Adobe iFilter.
I was able to reproduce the issue and the following resolved it for me. See if this resolves it for you all as well.
Here is how to get Adobe Version 11 PDF filter to work.
1 . If you haven’t already, run the following in SQL Server:
Sp_fulltext_service ‘Load_os_resources’, 1
Go
--you might also need to run: sp_fulltext_service ‘Verify_signature’,0 --This is used to validate trusted iFilters. 0 disables it. So use with caution.
--go
2. Stop SQL Server. (Make sure FDHost.exe stops)
3.
Uninstall the Adobe ifilter (because it defaulted to having spaces or the folder name is too long).
4.
Reinstall the Adobe iFilter and when it prompts for where to install it, change it to: C:\Program Files\Adobe\PDFiFilter
5.  Once the installation finishes, go the computer’s Environment variables. Add the following to the PATH.
C:\Program Files\Adobe\PDFiFilter\BIN
NOTE: it must include the BIN folder
NOTE: If you had the OLD location that included spaces, remove it from the path environment variable.
6. Start SQL Server
7.  IF you had an existing Full-text index on PDFs, drop the full-text index and recreate it.
8. You should now get results when you run sys.dm_fts_index_keywords('db','tblname') --Note: Change db to be the actual database name and tblname to be the actual table name.
Give this a try and see if this fixes yours.
Sincerely,
Rob Beene, MSFT

How can I copy part of a larger PDF file and create a smaller one?

How can I copy part of a larger PDF file and create a smaller one?

Hi,
Copy the content of PDF file in Adobe Reader and paset it to MS Word then create PDF file from the Word file.
This may not work for all PDF files as some PDF files are not created correctly or some content cannot be copied.
Acrobat XI Pro has features to extract/delete/crop pages in PDF files and you can download it from www.adobe.com(Trial version- 30 days free). Or you can upgrade your subscription to Acrobat Plus and see more information at https://www.acrobat.com/acrobatplus/en/home.html

I can't edit text on a pdf file in adobe acrobat

I need to edit the text on the pdf file but I can't and this message keeps showing up: " This form cannot be edited in Acrobat. Please use Adobe LiveCycle Designer to edit this form.
There are no security on this file. The only thing that is not allowed is to create templates. When I check the document properties description, on the PDF producer it says adobe distiller 7.0.5 (windows)
I downloaded the adobe livecycle designer but I couldn't edit the text there either... When I open the file it says the text is not downloaded so it replaced it with another text, I clicked ok but then the text didn't change, This message showed up:
I really need to edit the text on this pdf file because it's important. Can anyone help? Greatly appreciate it. By the way, this is a pdf fillable form that you can fill out on acrobat and that is the only thing it seems like it will let me do this file. I don't want to fill it out, I want to edit whats on it. It's one of those forms that you get from NJ courts.

Ok, what we can tell you is that if this is a LiveCycle form (and we can be pretty sure it is), that you are absolutely right. Acrobat can fill it, and nothing else. These are a very special kind of PDF, where all the text is in a special XML format that Acrobat can only show, not edit.
So, you are on the right track: if it can be edited, you need LiveCycle Designer. Unfortunately, we don't know much about it in this forum, so please try posting here: http://forums.adobe.com/community/livecycle/livecycle_modules_and_development_tools/livecy cle_designer_es
If the form is publicly available, it may help if you include the URL (web address) when you post.

Can't download large pdf file

I'm trying to download a large pdf file (26.2 mb) to my iPad. It appears to download, then appears, as 440 blank pages. It offers to open the file in iBook, but that also doesn't have any results. Is there a limit on the size of the pdf file it can handle? I tried to e-mail it from my computer, but the file is too big for my e-mail program. This is a book I would really love to read on the iPad--how can I get it there? thanks, B.

Yes, I see that as well. Talk about a bad assumption. I thought from what I had read that the feature worked like Spotlight on the Mac. In fact I could swear I've read that on Apple's site somewhere. Not the first time I was wrong and certainly not the last. Alas I stand corrected again.
Frankly, after investigating the search function further - IMHO - it seems pretty useless. A number of the apps that I use have their own search functions built in. I've read that you can search for a missing app on your iPad with this feature, but other than that and finding contacts and emails it seems pretty pointless to me.

A pdf file failed to convert to word, presumably because of size. how do i split a large pdf file into manageable secrtions?

I'm running Abode Reader XI version 11.0.7. Repeated attempts to convert a large (439 page) file, a dissertation, failed. How do I split a large pdf file like this into manageable sections for conversion?

Hi Mike,
Your 11MB file is well within the file-size limits for ExportPDF, but depending on the number of pages, complexity of the file (and yours doesn't sound complex), and your connection speed, it is possible that the service is simply timing out before it can finish processing. These steps can help:
If the file already contains editable text (that is, it isn't a scanned document), try disabling OCR as outlined in this this document: How to disable Optical Character Recognition (OCR) when converting PDF to Word or Excel.
Clear the browser cache and try again.
Try a different browser.
Let's start there. If you still can't export the file to Word, let me know and we'll take it from there.
Best,
Sara

I want to save large pdf files from my computer to my iPad so I can view them in Adobe Reader.

I want to save large pdf files from my computer to my iPad so I can view them in Adobe Reader. I do not want to view them in iBooks or Quickoffice. Since I cannot email these large files, how can I get them on my iPad? Thanks for your help.

I think that Adobe reader supports file sharing.
Connect the iPad to your computer and launch iTunes. Select the iPad on the left side under "devices". Click on the Apps Tab in the window on the right. Scroll down to the File Sharing Apps list under the main apps list. Click on Adobe Reader. Drag the documents into the file sharing window on the right or select them using the "add" button.
Launch the Adobe reader app and the files should be in there.

Large PDF file (ebook) on ipod touch to read?

I have a large pdf file (7.0 mb, 445 pages) that I want to be able to read (without killing my eyes) on my overseas flight. I added the file via an app called file magnet. But it ran low on memory and crashed. Plus the text was very small.
I love the way ereader pro works but unsure if those books are in pdf format. Or if I can even add my own books?
Is this idea even possible for me to do?
I would be
a) willing to reformat the document if need be.
b) pay for an app that would allow this.
and/or both...
Thanks in advance for your help.

There are several iPhone/iPod Touch apps that can read PDF files. However, the ones I have found to not re-flow the text (if you find one, let use know).
While less than perfect, you can use the free desktop Stanza app
<http://www.versiontracker.com/dyn/moreinfo/macosx/34623>
to convert a PDF to an ePub format which can be read via the free iPhone/iPod Touch Stanza app.
The iPhone/iPod Touch Stanza app can then change the font size, text color, background color, etc... And Stanza is a nice eBook reader.
The iPhone/iPod Touch Stanza app can download eBooks via several methods. From web sites that support Stanza (such as FictionWise, Project Gutenberg, etc..), from your own web server if you specify the link as stanza://path/to/ebook.epub, or you can enable the desktop Stanza -> Tools -> Enable Sharing, which will allow your iPhone/iPod Touch pull eBooks current displayed on the Stanza desktop into your the iPhone/iPod Touch Stanza app.
However, I will warn you that the PDF to ePub conversion leaves a lot to be desired, as a lot of formatting information is lost, but it is readable and you can most definitly change the font size and other font attributes.

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?

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...

I cannot edit text in a PDF created from scanning

I am using Adobe XI, and I have created a PDF by scanning a document.
When I do click on a paragraph to edit text, all the page appears selected, it seems to be an image. At that moment a message pops up saying: this page has not editable text or digitalized content. The editing tools are disabled, so I cannot edit text.
If I do export a page to Excel or Word, I can edit text there, although there are some kind of data that is not converted properly (even when I have executed OCR).
I have edited preferences, but I am not sure if I did it correctly.
Thanks

I am using Acrobat XI Pro on PC.
Of course, I have done all the steps you mention, but I wanted someone to confirm me if these setting values are correct in order to obtain the best results. I repeat the paragraph of my previous discussion that I want to clarify, just in case some of you can help me, mainly about optimization
I digitalized the document from the scanner. This scanner is installed in the net, so I personalized the settings in Acrobat and I chose memory mode instead of native mode.
Mode color: black on white
Resolution: 600 ppp
As you say in your mail, I understand I should choose ClearScan OCR not searchable just at this moment.
Well, and what about the options of optimization?, JBIG2 (without lost)?, 4 CCITT?
And filters?, I have: activated, low, activated, medium
Are these values congruous or compatible?
Thank you
