That's what I figured... thanks for the quick reply.

A BT without a matching ET is an error. If you have any other
operators than those allowed inside BT/ET, it's an error.

Somewhere in your program, you've always had an unbalanced number of
BT/ET pairs. If you take one of your old PDFs (that was built by the older
iTextSharp) and run it through Acrobat Pro's syntax checker, you'll find you
have a problem. Adobe's smart enough to Figure It Out, but there are quite a
few other PDF viewers floating around these days that are not.
That's why I added the code to catch the unbalanced pairs, and why the
rest of the team agreed that it was a good idea. IIRC, the same sort of error
is thrown with unbalanced q/Q pairs, though the verbage may be different...
And now I can't find where I put the check for BT/ET...
Ah yes... sanityCheck(). And because it's throwing during a newPage(),
that means you have a BT without an ET somewhere in your page's text stream.
Not in the direct content, and changing that won't affect the text ContentByte
one way or the other.
It's technically possible that we are throwing in error. For Example:
q
BT
(blah)Tj
Q
I'm not sure how the PDF spec handles this Weird Case, or even if it
has anything to say on the matter. Lets see...
"A text object begins with the BT operator and ends with the ET
operator, as shown in the Example, and described in Table 107. "
So the above content example is either illegal, or still inside a text
object after the Q. We're fiine... but there's some wiggle room here in the
spec that makes me uncomfortable. "Alarmed" even. Leonard, am I reading this
right?
Text state is also kinda independant of the regular graphic state.
Text attributes within a BT/ET pair are local to that text object. BT/ET is
kind of text's version of q/Q. I would therefore hope that q BT Q parses as an
unclosed text object, but a retentive reading of the quoted line would make q
BT Q ET legal... like I said, "alarming". I'm poking around in the q/Q verbage
for something to support/reject this interpretation, to no avail.
These operators have been around since PDF 1.0... I'd be shocked if
this question hasn't come up before.

The only problem I can see here is that you are still ignoring
the request for a simple, complete, standalone example. I'm ok you that, it's
your problem, not mine.

Referring back to my first example with ColumnText(),
the internal buffer of
the ColumnText ct reads just before the document is
closed:
Canvas = {BT
1 0 0 1 163.67 479.06 Tm
/F1 26 Tf
(Astrologisches Porträt)Tj
ET
}
This looks pretty much ok, BT being short for
BeginText(), then comes the
SetSimpleColumn(...), followed by the phrase (preceded
by the chunk's font)
and ET for endText(). But, upon CloseDocument() the
Unbalanced begin/end text operators
error appears. Can anybody see a problem here ?
