Re: Problems with display-align

[Bradley Harrington <bh...@us.ibm.com>]

Jeremias,
      I played with it a little more.  I realized that if I get the static
content overflow warning, then the cell alignment drops to default.
However, I got that warning even though the image I embedded in the header
is smaller than the before-extent (0.5in vs. 0.45in).  I am assuming the
table is creating the extra space to cause the overflow.  If I change the
image size to 0.4in, things work correctly.  Here is the stylesheet and the
warning generated. I don't know if this is a bug for you or not.  Thanks
for the help though, I would've never figured this out on my own.

FOP puts images into lines, like everything else, and adds additional
space (the half-leading) before and after the line. The half-leading
is calculated from the line height, which is in turn calculated from
the font size in effect at the beginning of the block, unless
explicitly overridden. If you want to take the line exactly as much 
height as the image set the line-height or font-size to 0. (if you put
text in such lines, they will look "glued" together)
