convert a file (.txt,.pdf..) into a stream file

    char *token = strtok( const_cast<char*>(fil.c_str() ), "/" );
    std::string name;
    std::vector<int> values;

    while ( token != NULL )

        name=token;

    }
    std::strig f_name=name;
}

When I try to load the .pdf file I have an error "unable to read. PDF IS DAMAGED". WHY? This code works for .txt files and .cpp files. I've tested it. I am currently working in ubuntu c++ code. I've also used the base_64 encode/decode because this was the request.

  • Do you have permissions to read that file? –  Aug 29 '11 at 13:32

    Also you probably shouldn't try to read binary files without the binary flag and with `getline`. Or with `c_str()` – Seth Carnegie Aug 29 '11 at 13:33
  • yes i have permision to read the file. Where am I wrong? – sunset Aug 29 '11 at 13:35
  • @sunset what is the _exact_ error message you get? – Seth Carnegie Aug 29 '11 at 13:36
  • @sunset also what are you trying to do? You're probably doing about it wrong. – Seth Carnegie Aug 29 '11 at 13:37
  • I am trying to put in a string a pdf file. – sunset Aug 29 '11 at 13:40

    @sunset you can't modify a binary file like that, you're going about this completely wrong. You'll need to find a PDF library and use that. – Seth Carnegie Aug 29 '11 at 13:45
  • Two things come to mind: 1) not opening the file in binary mode might cause you to read the wrong data. 2) reading with `getline` discards linebreaks. – Kerrek SB Aug 29 '11 at 13:45

    You are aware that pdf files are not plain text? they have a very specific format that has to be followed? See http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/adobe_supplement_iso32000_1.pdf – RedX Aug 29 '11 at 13:45
  • You did not really provide much more information as in http://stackoverflow.com/questions/7229774/convert-a-file-txt-pdf-into-a-stream-file – PlasmaHH Aug 29 '11 at 13:46
  • is there a way I can solve this problem? And also Is there a way I can change getline in order to have the linebreaks? – sunset Aug 29 '11 at 13:49
  • @sunset: off topic, code should be [indented](http://en.wikipedia.org/wiki/Indent_style) for readability. – outis Aug 29 '11 at 14:55

Try this: http://sourceforge.net/projects/libharu/

I saw it recommended in a few different places, including a couple different SO questions - but all they gave was the link.

It's a free, open-souce library for PDF reading. It probably isn't as easy as you want, but I think its as easy as you're gonna get and its free.

It's also multi-platform so should work on UNIX and windows.

Try opening with:

ifstream file ("/home/sensor.pdf", ios::in|ios::binary);
