block-progression-dimension: how it works?
This block-progression-dimension is driving me crazy. Probably I didn't
understood how it works... well, this is the problem:
I must create a table with 3 rows and 2 columns. The width of 2 columns is
fixed (say 2cm and 16cm) and the height of the whole table is fixed too (say
20cm).
The 3 rows must have an optimum height of 30%, 40% and 30% (say 6cm, 8cm and
6cm). This is in the most cases.
Sometimes, depending on the content, one row can exceeds the optimum height:
because of the condition of table height, can be useful if such growt can be
achieved by reduction in height of another row.
Say for instance:
right case: row heigths are 6cm, 8cm, 6cm.
worst case (the last row needs 7cm because of his content): 6cm, 7cm, 7cm,
or (better) 6.5cm, 7.5cm, 7cm.
I assumed (and probably I was wrong) that
block-progression-dimension.minimum, block-progression-dimension.optimum,
block-progression-dimension.maximum are designed for such purpouse.
No way to have this to work on a table:

I discover that this is a FO limitation too ;-)
I solved creating an extension to Saxon. I pass the nodes as
parameters and the exstimate the resulting heights programmatically
with Java2D and adopt a strategy to obtain a fit (including a font
resize if necessary). The extension return the final evaluated values
to xslt and here it is possible to use such values in
block-progression-dimension attribute.
It works fine.

Hi Giuseppe,
This is a FOP limitation, as you found out the hard way. FOP does not
make use of the flexibility in block-progression-dimension to adjust the
height of the block according to the content. It uses only the optimum
value. Likewise for tables: a table row will only grow as much as
necessary to accommodate all its content, but the potential slack will
not be used.
Sorry,
Vincent
