Re: [docbook-apps] dbfo-need height in FOP 1.0

["Bob Stayton" <bobs@sagehill.net>]

Hi Sam,
Actually, you prompted me to revisit this feature.  A block-container was used because 
you can set a fixed height on it to take up the needed space, and a regular block does 
not.  However, I thought I would try a table with a single row whose 
block-progression-dimension is set to the height, and that does work in FOP 0.95 and 
1.0.

However, the other part of the need template is managing the vertical space so that it 
does not introduce extra space.  And FOP 1.0 does not support 
space-after.precedence="force", so it cannot properly manage the space.  The visual 
result is that a section heading that is bumped to the next page will express its 
space-before value before the heading.  This leads to too much space at the top of the 
page.

Normally a space-before property is suppressed on the first block on a page, so the 
heading would appear at the top without its space-before.  But the dbfo-need blocks 
interfere with that because they become the first block of text on the page.  What 
should happen is that the last dbfo-need block sets space-after="0pt" and 
space-after.precedence="force", whose effect is to override the heading block's 
space-before value.  However, the space-after.precedence="force" does not yet work in 
FOP, so you get the extra space.

So FOP is closer to supporting this feature, but not quite there yet.

I just gave this a shot and it did not appear to work in FOP 1.0.
I also see that they haven't added XSL-FO 1.1 indexing extensions, yet.

Is there any reason that this PI has to work using the block-container
trick? If you made a processing instruction that created a regular
block that had both a keep-with-next.within-column="always" and
keep-with-previous.within-column="always"?
