encoding/decoding a pdf file

[theguy0000]

Hello,

I am trying to figure out how to read and write pdfs, but I cannot find any info on how they are encoded.

I created a simple pdf by using on of those printer programs. It says "Untitled" at the top, then "Hello", then at the bottom "Page 1". That's it, just that one page in the whole document.

A FileRead ( ) of that pdf file gives me this:

%PDF-1.3
%Çì¢
5 0 obj
<</Length 6 0 R/Filter /FlateDecode>>
stream
xœMŒÍ
Â0„ÑÚª«ø{¬‡®›íO’« ž-9öV± Th}0
î\†™ogB&%ÈA?Ópj5oˆ1¶×¯™˜ÀP.ÿ¾ñìü£AK¶¶J£{

I can make neither heads nor tails of that. Well, I can get the obvious info, but not the author or anything. Performing a String ( ) on the fileread'ed info gives me a ton of random letters/numbers, which also make no sense...

Google has led me nowhere.

Anyone have any idea?

edit: omg wrong forum :"> please move to v3 support

and reading, rather than decoding;

$oPDF.src="C:\Program Files\Adobe\Acrobat 7.0\Help\ENU\Reader.pdf"

When working with PDF's I found it was easier to have the SDK provided by Adobe. It actually costs $99 for a single license, but if you have Adobe Acrobat installed the COM Objects are already there, but your target system will also need Acrobat installed.

The Acrobat SDK its now again available for free: http://www.adobe.com/devnet/acrobat/

If you want to en/decrypt you may use a free command-line tool: http://www.accesspdf.com/pdftk/

Ah thank you! I didnt know they had released a free version. That is awesome! I will have to re-code a couple of my applications.

THANKS A MILLION!
