z-index status

["Jesper Thorhauge (JTH)" <JT...@zenaria.com>]

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........

RE: z-index status

[Arved Sandstrom <Ar...@chebucto.ns.ca>]

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
