Tom,
That was very good information. Explains a few thing I wondered about in
recent past.

Subject: RE: Strange Things when reading PDF files
Just for interest I took the following from an article from adobe. It is
talking about the [change accessability reading options] screen found under
the document menu.
"Use the third screen to choose the reading order for documents that
are not tagged. The following options are supported:
Infer Reading Order From Document (Recommended). When this option is
selected, Adobe
*
Reader determines the reading order of untagged documents using an advanced
method of layout
analysis. This option is recommended because it is most likely to provide
the most accurate results.
It does, however, require more analysis and therefore may be slower than the
other two options.
Left-To-Right, Top-To-Bottom Reading Order. When this option is selected,
*
Adobe Reader interprets the reading order of untagged documents starting
from left to right on the page and moving from top to bottom.
Use Reading Order In Raw Print Stream. When this option is selected, Adobe
Reader
*
interprets the reading order of untagged documents based on the raw code in
the
PDF document - essentially, the order text was recorded in the print stream.
When you choose either of the last two options, Adobe Reader does not
include
form fields in the content, and it does not recognize tables.
Depending on the complexity of the PDF document, on-the-fly tagging may not
adequately
capture the intended reading order of the document. Many PDF documents have
multiple
columns or complex page designs that can affect how well Adobe Reader
interprets the
content. If you are having trouble reading a particular PDF document, you
can experiment
with the various Reading Order options to see if one works better than the
others.
The next control on this screen is a check box labeled "Override the Reading
Order in Tagged Documents."
While the Reading Order options above apply to untagged documents by
default, this option causes Adobe
Reader to use the reading order you selected (instead of using the reading
order specified by the tag structure)
for tagged documents as well. This option is useful if you receive PDF
documents that are poorly tagged.
The final control on this screen is a check box labeled "Confirm before
Adding Tags to Document." When
you select this option, Adobe Reader asks you to confirm its tagging options
before it prepares an untagged
document for reading by your assistive technology. Tagging can be a
time-consuming procedure, particularly
in larger documents, and this option alerts screen reader users when that
procedure is about to begin."
I hope this is of some use.

Hi there,
I have seen this over and over. There are small boxes sometimes, not in
story books, but rather in theory books (such as the books in the For
Dummies series (E.G. programming in C++ for dummies, ASP.net for
dummies) and the Idiot's Guide to whatever books) that make a line break up.
Let me paste a bit of a book called the Complete Idiot's guide to Yoga that
I found lying around. See?

As you see, lines seem to get cut off, and you seem to have two things
talked about in one line. Is there a way to split these two, such as a
table-like structure one could navigate?
Thanks!
