Hi Daniel,
I see from the compliance page that absolute positioning is
implemented. However in practice I have an FO file which uses absolute
positioning and it seems like it doesn't take effect at all.
I culled all the containing elements from my FO output just in case
they were to blame somehow, and the issue still occurred. Here's the
block (apologies in advance for the way this is going to break):
<fo:block margin-left="0pt" margin-right="0pt" id="SlideObj"
font-size="16.0px" unicode-bidi="embed" visibility="hidden">
<fo:external-graphic content-height="scale-to-fit" content-
width="scale-to-fit" scaling="uniform" src="url(file:/C:/Users/
Daniel/Desktop/testppt_files/slide0001_background.jpg)" absolute-
position="absolute" height="100.0%" width="100.0%" left="0.0%"
top="0.0%"/>
Just a quick FYI:
don't expect the 'absolute-position' on fo:external-graphic and
fo:inline to have *any* effect at all. The Common Absolute Position
properties apply to neither of those FOs.
Just to add to what Andreas has told you: absolute-position does apply to
block-container. So you can absolutely position block containers but not
blocks, inlines or external-graphics. I also noticed that you are using
percentages for width/height/left/top. That may work. I personally have
only ever used absolutely positioned BC with units specified in mm. Also,
note the subtle difference in meaning between absolute-position="absolute"
and absolute-position="fixed". IIRC, the "fixed" setting must be used to
position the BC relative to the top left of the page.
Well in actual fact, it isn't "me" using percentages or fo:inline, as it's
coming out of someone else's library. :-)
The best I can hope to do is contain things in blocks if they can't handle
the absolute positioning themselves, by using XSLT.
Problem is that even if I take the example above and wrap
<fo:block-container> and <fo:block> around the inlines, it still doesn't
work as expected. But I imagine the transform I've already done here has
somewhat improved the validity of the FO output.
