Attached pdf has all pages blank

Attached pdf has all pages blank

Post by john.okel » Sat, 26 May 2007 00:39:40


Someone sends me a pdf file as an attachment. I receive it in Eudora,
open it with Adobe Reader, or Acrobat, and it has no text or images.
All pages are blank.

If I go to the server website -- before Eudora has processed the
attachment -- and open it there it works fine. So it looks as if
Eudora is scrambling the file somehow.

I know this problem has been aired in the past, but none of the
threads reached a solution. Has anyone found one now?

Grateful for any help. John

If you are opening the PDF from Eudora, then the hook (or link) to the
external program (Adobe Reader/Acrobat) isn't working as it should. Try
Saving the PDF to the desktop (or some other folder) and opening it from
there. If that doesn't work, there is a more serious problem than a
broken hook.

You could try reconfiguring Eudora: cancel the hook to Adobe
Reader/Acrobat, shut down Eudora, restart, and reset the hook. This
sometimes works (with any program that calls another one) - depends on
why the hook is broken.

Another possibility is that your spam filter is over-zealous.

Er, that's all I can suggest.

In article < XXXX@XXXXX.COM >,



That pdf should be in your Eudora Attachments Folder. Open the file from
there, in Preview, in case there's something weird going on with Adobe
Reader.

Thanks to both for your suggestions.

I do try opening the blank pdfs from the desktop and the attachments
folder, with Adobe Reader and with Preview. Same result: all pages
are blank. Same for opening from within Adobe Reader.

PDFs from other people all work fine: this only happens with one
sender. And as said, his pdfs open fine on the email server. They
only go blank after Eudora has downloaded them.

So I conclude the problem must lie with Eudora.

Someone aired the same problem in 2000, but no one had an answer.

Maybe something to do with character sets? There is a posting at
http://www.yqcomputer.com/ +mac+pdf+attachment+blank+pages&rnum=2&hl=en#86e3db41ee6c6a8d
and a long discussion at
http://www.yqcomputer.com/ +mac+pdf+attachment+blank+pages&lnk=nl&hl=en&
but they are too technical for me to follow.

I conclude the problem may lie with his PDF creation software. IOW,
there may be some non-standard feature that Eudora cannot deal with, or
else sees as something evil. What is he using? Do other of his
correspondents report the same problem?

NB that most current word-processors claim the ability to create PDFs,
and there are also a number of freeware and shareware PDF editors out
there. There is no guarantee that their products will be 100% compatible
with Adobe's standards. If he is using Adobe on a Windows platform, some
update for Windows may have bollixed things - Windows updates always
have unexpected side effects, many of which don't show up for a while,
and some of which are limited to relatively few machines.

Also, Adobe updates its reader from time to time. Again, there is no
guarantee that these updates will not trigger some bug.



Um, yes, character sets might be an issue, but I have no experience with
that. I just use the defaults. Sorry.

Perhaps an Adobe newsgroup or e-list can help you.

I've tried both. I use Eudora to download the message and attachments
to my hard disk, then open with Acrobat Reader and get blank pages.
Or I use Firefox to go to my inbox on the server and open the
attachment there, still in Firefox, and get the text.
How do I tell if it is so marked or not?


Is the following what you had in mind?
MIME-Version: 1.0
Content-Type: multipart/mixed;
boundary="------=_Next_Part_3011653798.529"


My institution provides a web-based interface with the mail server so
I can use a browser to see mail in my inbox.

and does it provide a "raw" view
If "raw" means something like this --
<x-html><!x-stuff-for-pete base="" src="" id="0" charset="/
macintosh"><HTML><HEAD><style type="text/css">body {font-family:
arial, sans-serif;}</style></HEAD><BODY><P>Here is an itemised
itinerary for your forthcoming travel arrangements for booking
reference CPF004643465, a copy of which you may want to leave with a
friend or relative.</P><P>Have a pleasant trip<P><P>
-- then I can see that after downloading via Eudora, but not when the
message is in the Inbox.

Does this help with a diagnosis? Thanks for your interest.

That specifies what string
will separate each subsequent attachment,
but I meant the header part of the PDF attachment itself,
like this one which I just sent to myself:

--=====================_361293081==_
Content-Type: application/pdf; name="SevenColors.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="SevenColors.pdf"

The first few characters of the PDF file should also be
a standard PDF header; for this file it happens to be:

%PDF-1.2
%<bh:c7>

If you can't obtain the actual first bytes from the stored file,
the first line of the "base64" encoding (following the header)
would suffice, as we can decode that, such as on-line at:
http://www.yqcomputer.com/

Any comparison of PDF attachments (headers and first bytes)
which are okay, vs. those not okay, might also be helpful.
