Of course, you could be setting the height of that container to 20mm (not
1in) and setting the following block padding to -20mm - {font-height} of the
heading.

By the way, this would have the effect that if the block-container height
does not fit at the end of the page, it will move to the next page. This is
as close as you can get unless you wanted to clip the image at the end.

Thinking of this again and I have not tested all things, but what about
doing something like this (essentially putting down the block-container with
nothing in it except the background image and then setting the padding at
the top of the following text content to recapture that height).

<fo:block-container height="1in" background-image="url(20.jpg)"
rx:background-content-width="20mm"
                rx:background-content-height="20mm"
rx:background-scaling="uniform"
                background-repeat="no-repeat" >
                <fo:block><fo:leader/></fo:block>
            </fo:block-container>
            <fo:block padding-top="-1in - 12pt"><fo:leader/></fo:block>
            <fo:block space-after="6pt" font-weight="bold"
font-size="14pt">Heading</fo:block>
            <fo:block space-after="6pt" >Accusam invidunt consetetur est

I believe there is no solution with pure XSL FO. The behavior you describe
is according to the standard.

Your attempt is probably as close as you can get as you have not specified
what the behavior you would expect if it is such that the image would not
fit at the end of the page and yet your rules would allow for the paragraph
to start. If you cannot solve or express that, you cannot even have a
solution as there will always be a case where it does not work.

If you use the XEP Intermediate format and inject the images in the pages
after composition, you can solve "part" of the problem. With this solution,
you could place a rx:pinpoint marker at the place wherever you wished an
image and then output that image in the XEP Intermediate Format only once
for each rx:pinpoint. But you would also need to fully describe what is
intended visual representation at the end of a page/column where the text
fits and the image does not.

page/column

Hello,

We are having a problem with unwanted repeating of a background image when a
block spans a column or a page. Is there any way to disable this?

The offending block:

                <fo:block background-image="url(20.jpg)"
                            rx:background-content-width="20mm"
                            rx:background-content-height="20mm"
                            rx:background-scaling="uniform"
                            background-repeat="no-repeat"
                            margin-left="0mm"
                            padding-left="2mm"
                            space-before="11pt">

The version of xep used: XEP 4.21 build 20121114

For an example of the resulting repeat, see page two of the pdf.

If this block continues in the next column on the page, or just onto the
next page, the background image is repeated. I provided an extremely
simplified stylesheet, datasource and resulting pdf with this e-mail.

I hope anyone can help, we already tried to let the block only wrap the
title and first paragraph instead of all the paragraphs. This reduces the
number of times the problem occurs but does not eliminate it. The generated
pdf will normally contain a multitude of articles so there will always be a
paragraph somewhere that will continue into the next column or page. Thus
for simplification, my example wraps all paragraphs.

If anybody has a solution that prevents the repeating, I would be very happy
to learn how that can be done.

Kind regards,
