break-before breaks span?
Hello everybody,
Todays question: Can break-before break span? If yes, why? If no, read on:
Attached you will find a small fo-file containing one simple page master and two pages. Although the page master has a column-count=2, both pages should be single-column, therefore span=all is used. Both pages should start at an odd page, therefore break-before=odd-page is used.
The unexpected result: The text on the first page uses both columns, the second page is empty, but the text on the third page uses only one column. When I remove the first page or break-before, the second text uses both columns. Why?
Regards,
Georg Datterl

grmblbl. Of course if break-after is set to "odd-page", then the second
block must start on an odd page. If break-after is set to "even-page",
then the next content must start on an even page.
Apologies for the typo. As if that weren’t confusing enough already...

See section 4.8 of the XSL-FO 1.1 specification [1]:
“A break-after condition depends on the next formatting object in the
flow; the condition is satisfied if either there is no such next
formatting object, or if the first normal area generated and returned by
that formatting object is leading in a context-area.”
So in the present case, there is a next object (the second block), and
the break-after="odd-page" specified on the first block forces that
second block to start on an even page.

This is a bug, unless the term ‘flow’ used in section 4.8 actually
refers to fo:flow. But I don’t believe so.

Why would that be a bug? The way I see it, the first block finishes on
page 1, which is already an odd page, so the break-condition is
satisfied, simply by breaking the page there. No empty page needed.
Interpretation:
break-before="even-page" simply means "the first area generated by
this FO should end up on an even page"
Somewhat counter-intuitive, break-after="odd-page" actually means "the
first area /after/ the last area generated by this FO should end up on
an even(!!!) page"
OTOH, there does indeed seem to be a slight glitch, in the sense that
break-conditions do not appear to be checked across page-sequences.
Take this:
<fo:page-sequence master-reference="contents" initial-page-number="2">
<fo:flow flow-name="xsl-region-body">
<fo:block span="all" break-before="even-page" break-after="odd-
page">
[Text]
</fo:block>
...
Then we get no empty page before, as is expected, since we are already
on an even page.
If you add a second fo:block, then you get an empty page in between
the two blocks. Again, as expected.
BUT: if you move the same block into a second page-sequence, the empty
page disappears again.
Cheers
Andreas

So after my correction to my previous mail, with break-after="odd-page"
there should be one empty page and the second block should start on page 3.
FOP 0.94 gets it wrong since it creates one empty page when break-after
is set to even-page, and indeed two empty pages with odd-page, instead
of respectively 0 and 1.
FOP 0.95 doesn’t seem to honor the break at all. So please still report
a bug ;-)

Hmmm, I didn’t receive anything, so you may want to send it again. My
address is not only for mailing lists, but don’t tell anybody ^^

Vincent

I'm not quite sure what to report here, since no empty page in case of break-after="odd-page" is the desired result.
P.S.: Did you get my mail last Thursday or is this address only for the mailing list?

I guess you use FOP version 0.94? I can reproduce that, but starting
from 0.95 no empty page is created at all, even when it should be the
case (break-after="odd-page").
Another bug, I guess, that we would be grateful to you if you could also
report it on bugzilla.

Hello again,
To keep this thread alive, I tried using break-after. Using break-after="even-page" does what I would have expected from break-before="odd-page", but break-after="odd-page" creates TWO empty pages. Why?

I don't think so. Unless I'm missing something, the behavior you
describe is a bug.
If you want, please log this issue in Bugzilla, so it is not lost.
Thanks!
