Font Dimensions
I'm trying to understand how text is dimensioned vertically. If I put text
into a fo:block I notice space occurring before and after the text in
addition to the height of the font itself. How do I figure out how much
space is placed above and below the font so I can come up with a total
amount of space that will be used vertically in a particular fo:block?
space above the letter + the letter height + the space below the letter = ?
Is there a way to calculate this? Does the space above and below vary
proportionately to the font size specified for the letter?
Can someone point me in the right direction with a link or an explanation?

You can control the space before and after a block by using the space-before
and space-after attributes. For example:
<fo:block font-size="10pt" space-before.optimum="10pt">
Hi There
</fo:block>
You can check out the spec at
http://www.w3.org/TR/2000/CR-xsl-20001121/slice7.html#space-before
I believe that FOP supports space-before.optimum and space-after.optimum
only (not the other options like minimum, maximum, etc.). I'm not exactly
sure what the default values are.
Cheers,
Scott
