Subject: Excess tags in acrobat?
No previous message | Next message →

I have been going over some legacy content for my school's pdfs, and I've
been noticing that some of the larger documents are causing memory leaks in
acrobat, and upon inspection I've been finding a lot blank tags that
apparently have nothing in them, and once I remove them from the document
it clears up the memory leaks and I'm able to get the rest of the document
running smoothly. Has anyone else encountered this issue?

The tags also do not follow logical reading order, so instead of the
document tags running 1 2 3 4 5 6 7, they come out like 5, 2, 1, 4, 3, 7, 6
(as an example).

Could this be because these documents are older? I've also noticed that
they had some tables scanned in (not original electronic format, a scan of
a table printed out). My boss is asking for the nature of these issues and
I just wanted to have a more solid answer than just a hunch.

Thank you for your time,

Laurie

In my experience, it sounds like it could be one of several things:

-Acrobat "auto-tagging" a document that was not initially created with tags.
-An export from a desktop publishing program that is reflecting the order
things were added to the document, instead of the logical flow
-Maybe OCRed...

You -can- move tags around to fix order... but the tags panel is clunky and
difficult to really do extensive work with.

Note- I found out the hard way there is a feature to "remove blank tags"
from the pop-up tags menu that might work.

The only thing I could think of causing a memory leak is if there were
thousands of them. I'd weigh something like embedded fonts as more probable
to cause a leak.

Go to the pages pane, select all, properties > there should be three
options, choose tags (I don't have access to Acrobat this minute). In
short, the tag order is key, not what the order pane says.

Making changes to the tags in the past would cause the size of the PDF file to increase. There are some tools in Acrobat to help -- as mentioned new versions have the delete empty tags and the "print production" features have a number of hidden tools for clearing up clutter in the document, syntax checking, and PDF/UA checking that you may find helpful.
