Exporting to PDF puts horizontal lines across my Pictures!

[zoomiest]

I am building a family pedigree chart in MS Visio, to go on our wall, and have included a number of photos.

For some reason some photos (not all) have been completely wrecked by horizontal lines after exporting to PDF.

How can I fix this?

Here is the PDF to see what I am talking about. http://www.jones.cx/share/talks/Shields-Side-II-Final.pdf

I have rescanned the photos and saved them to TIFF, BMP and JPG with same results.
I have saved them to 1200 dpi to see if higher resolution would help... same results.

Any thoughts?

I am using Adobe Acrobat 8.1.0 on MS Vista (OS).

Any help would be greatly appreciated.

Because you have Acrobat, don't export the file to PDF, but create the PDF
by printing to the Acrobat PDF printer driver, and see if that would fix
things. If it does, you will know a) that the problem is in Visio and b)
how you can work around it.

I have examined your pdf file in "Adobe Acrobat X Pro"
(Version 10.1.3)and extracted all the images
to my filing system.

I.
Menu bar-->File-->Create-->PDF from Web Page-->
URL: http://www.jones.cx/share/talks/Shields-Side-II-Final.pdf

II.
Meuu bar-->View-->Tools-->Document Processing-->Export all images.


This made it obvious that your document has been comprehensively
mangled and chopped into far too many small pieces something which
is, I regret, typical for MS Visio files. (I got 138 files, many of which are fragments of text, not true images.)

Those images that do correspond to 'wrecked' scanned photographs are
indeed wrecked. It looks to me like a fault with an 'interlacing' format.

If you could give us a link to a couple of original hi-res Tiffs, one
that worked and one that didn't, I would be happy to produce plain-and-simple pdfs from them.

Technical note:
The pdf format does not even demand that
you embed the graphics files in the pdf, it can pull them in from an
external url (including a local "file://....." one), and they can then
be in their original non-pdf format.
You can also have more than one version of the same graphic: for example a lo-res one for screen viewing and a hi-res one for the
glossy-magazine edition. It can all be done behind-the-scenes because
the pdf software on your computer knows how to have a 'conversation'
with your pdf-enabled printer without human intervention.
