Re: [docbook-apps] Auto-font sizing for monospace.verbatim.properties font-size?

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

Hi David,
Unfortunately, there are no text fitting features in XSL-FO.  The stylesheet
has to specify the font-size, but there is no way in the general case for
the stylesheet to know if the text will fit.

But in the specific case of verbatim monospace text, there is hope.  If you
have a fixed line length, you could experiment to determine how many
characters fit in a line at each font-size.  Then you could create a
recursive template that finds the longest string between line breaks (
)
in a given element.  With that value, you could use an xsl:choose statement
to select the font-size that will accomodate that line length.  I didn't say
it would be easy, but it should be possible.  8^)
