Hi Arved
Thanks!
I’ll
might look into adding some kind of sorting to the fo-tree. Actually, what i
did in the project i’m working on was exactly the same J Before converting my HTML-layers
into fo:block-container, i performed a merge sort on the array holding the
layers to be written. Writing the fo:block-containers in “z-index order”
then produces the desired result. Anyway, i think i might look into adding the
z-index feature to FOP, as i don’t like my own workaround ..
Also,
why is it that the z-index property isn’t also a property on the
fo:block-container, but only on fo:block?
Regards
Jesper

Well,
here are some thoughts. As no doubt you have already gathered from Section
4.9.6 of the spec and also 5.4.5 most of the work is in the renderer. Take
into account that areas presented to the renderer are in a hierarchical
structure, _and_ also that areas can be relatively positioned or might be
fixed. It sure looks to me at first glance like z-index may require two passes,
with actual rendering occurring on the second pass, and the first pass being
used to create a different area hierarchy, ordered by stacking layer, with
positional calculations already carried out.
This is
the hard part and I don't think it will be exactly trivial but it should be
fun.
Inspection
of the code should inform you readily as to how the property is made known to
FOP and how you would ensure that
1)
inheritance according to 5.4.5 happens properly; and
2) a
z-index property on FO x is placed on generated areas as a trait of the same
name, so that it is available to the renderer.
Any
further questions and we'll be happy to help.
Regards,
Arved
Sandstrom

Hi
I
can see that z-index haven’t been implemented yet...i’ve read other
posts where people had the same problem as me, namely converting HTML stuff
(layers etc.) with z-index into PDF. Also, if anyone can guide me into the task
of implementing z-index, i would be glad to help ..! I would hate to do some
nasty workarounds in my application, re-arranging block-container’s etc.
etc
