not sure but how about using a free pdf to doc/txt tool?

missing the point. Where there is only the text version out there, derived from a not available pdf.

Trying to reverse engineer one I did pdf to text myself.

80 pin chip data on pdf with 1 to 24 pins L to R along bottom and vertical text text read from right , then anticlockwise. The horizontal text appearing in the horizontal on left and right edges appears as though scanned from right to left, ie swapped over. Also grey tone blocking of Vcc and Gnd maked them get lumped together when appearing in the vertical script

reference , is there a general principle concerning pdf to

Did you try converting the text file to .DOC first? I have done that a few times with some success.

112 pins in total

I'm assuming a pinout of the IC appeared buried in this gibberish , presumably something else mixed in there as was horizontal to the CXD one (part only)

Why do you need to convert it? You can download and read the whole pdf file from that link. The IC pinouts are quite readable.

Not available to me without registering for more unsolicted junk , I had to grab the Google-cached version. I tried proxies etc but no admittance

Just in case anyone has cottoned on to the intention of the thread. The following is for an 80 pin device originally on good pdf graphic as

24/16/24/16 pins. Starting pin 1 lower left corner and anticlockwise. Horizontal pinning with text vertical and Gnd text white in black block and Vcc in grey blocks.

I could not find a correlation between the mangled order and word length or word start or end position

It shows its probably a hiding to nothing. The same presumably applies to highlighting just a single block of "vertical " text. It will not copy across unscrambled. Both Foxit and Acrobat mangle that pdf-text to text conversion, maybe somewhere there is a pdf reader +highlighting/ pdf to txt app ,that does not mangle.

The pinouts 1 to 24 and 41 to 64 in the above table of 1 to 80 listing, I had to descramble manually

Not that it will help, but the (non)order is likely the order in which is was composed, using individual blocks of text. And it reflects the order of those layers within the PDF. The PDF contains positioning information for vector objects (like blocks of text) which is stripped out when converted to text only. Scott Dunedin, FL

Bugmenot usually has a couple of active Scribd IDs .......

I *WONT* run Flash here, but I can assure you PDFs can be downloaded from Scribd (if you have a valid ID & password) without it. Obviously the preview doesn't work! ;-)

If the text is stored as ASCII you can use any text editor like emacs to find the relevant text. I used to do this with WORD files in UNIX as well until they started using RAM techniques, splattering the text all over the place. THere is also a program on UNIX called antiword. And there is a UNIX filtering technique which I forgot where you remove any binary longer than two characters.

Is the command to debinary a pdf file in unix
