Subject [Xmlgraphics-fop Wiki] Update of "SpaceResolution" by JeremiasMaerki
Date Thu, 22 Sep 2005 07:03:14 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Xmlgraphics-fop Wiki" for change notification.

The following page has been changed by JeremiasMaerki:

The comment on the change is:

  '''Reminder''': an empty block (<fo:block/>) will not split a space-sequence, but
!BlockStackingLayoutManager currently adds a box (w=0) to the element list so an "id" present
on the empty block will still be registered by a later addAreas(). This will interfere with
the correct detection of space-sequences. This will need to be looked at, eventually. (Case
3d under 4.2.5 Stacking constraints!)
+ There's a note under 4.2.5 Stacking constraints that says: ''"The use of "stackable" in
two places in the above definition allows block-stacking constraints to apply between areas
of area-class xsl-before-float or xsl-footnote."'' That's bad since we don't know the before
floats and the footnotes at the time where we have to resolve the space specifiers.
  Someone seems to have started space-start|-end support (see !SpaceSpecifier and stuff in
!LayoutContext) long ago, before we introduced Knuth approach. We'll have to revisit that
since this has currently no effect on the inline element list but only on the areas produced.
That means that if you specify a space-start on an fo:inline you will get a space but line
breaking will be off. I hope we'll be able to use the stuff I'm building for inline-level
spaces, too.
