Is there a difference in the output PDF from Version 7.1.3.5223 to version 7.2.0.5881?

We have been using Adobe to read the indicator that tells our application that a page is portrait or landscape. As of yesterday, that indicator on both portrait and landscape pages is the same, '0'.

I have tested the Adobe "read" against older files and it still works on those. Any file created since Monday does not work.

Any thoughts?

I'd have to go back into our history database to determine what exact changes were implemented between those two versions but it's very much possible changes in PDF generation were implemented.
However, please note that PlanetPress's PDF files are generated using Adobe's own libraries... so most changes to the PDF's themselves are related to changes in the Adobe libraries (they are updated at least once a year). Whether or not those changes are compatible with Adobe's Reader is anybody's guess.
In any event, both those versions are very old and you should really consider updating to the most current version of PP-Suite. Other changes to the Adobe libraries have occurred since then.

Thank you for the update. Much appreciated.

I look forward to the results of your investigation.

Uhm... I wasn't planning on investigating. I was just stating that I'd have to investigate if I wanted to pinpoint the changes, but even then it wouldn't tell us much.

You have to understand that Adobe doesn't publish the method they use to determine whether a page is actually Landscape or Portrait. It involves quite a bit of clever guesswork and, as evidenced by your issue, it isn't fail safe. So again, trying to determine if any change in our code or in their libraries, anywhere, impacts their detection algorithm is nearly impossible.

Just to give you an idea: landscape does not necessarily mean a page's width is larger than its height. For instance, take a portrait page and rotate it 90 degrees: does it become portrait? Nope, it becomes rotated portrait. But let's say the text on the original page was written sideways, does rotating it make it landscape (because now the text becomes right side up)? Nope, it's rotated portrait... but the Adobe Reader may well tell you that it's actually landscape... or not (it depends on the percentage of sideways text vs. right-side-up text... plus some other clever detection parameters that we don't know about). And what if you had rotated that portrait page by minus 90 degrees? Then would the page be considered reverse rotated portrait or reverse landscape??? ... ouch, my head hurts...

I'm afraid there's not much we can do about this.

Ok, thank you.

If i wanted to roll back the Adobe - where would I look for that component?

Is Adobe installed as part of the Watch install? Last did a Watch install in 2010 - so not sure where the Adobe libraries get installed. I will investigate further. :-)

Thanks for the help so far.

You can't roll back the Adobe libraries in PlanetPress Suite. Either you rollback the entire installation or keep it as is.
If you make any modifications to the files installed with PPSuite, it WILL crash at some point.
