Hi, I'm a docbook newbie who has been testing the latest 1.7.5.1 epub
transform in Oxygen.
I'm having trouble figuring out the meaning of the epub parameters,
especially the ones related to cover. (see bottom)
I know that docbook has a cover element, but cover in the context of
epub parameters seems to mean something different. (Or am I supposed
to assume that the cover image information should be inside a
mediaobject element which is inside docbook's cover element?)
Does epub.cover.filename assume that the file is an html file or a
graphic file?
Will the epub.cover.image.id refer to a file name or simply be an
identifying attribute?
Finally, I see this note on docbook.xsl
!-- Via Martin Goerner: On covers: the IDPF2.0 standard
unfortunately does not have a provision for
covers. We had to add one and we did so in conjunction
with the IDPF and
various publishers. The tag chosen to define the covers is:
meta name=cover content=-reference to a manifest item-
Then, we also added a bit of logic to get rid cleanly of
the HTML cover
people usually add because the logical cover is not
specced by the IDPF. So,
if the HTML cover item is marked linear=no AND there is
a guide item of
type=cover pointing to it AND there is a logical cover
specified in a
meta name=cover tag, THEN, the HTML cover is discarded. --
I'm sorry; I don't understand exactly what this means. Does he mean
that in the html output from docbook you include cover information in
a meta tag ? Is there a file reference inside this meta tag?
Also, when epub.cover.linear = 0 or 1, what does that mean?
It would be nice to see a simple example of the values used to produce a cover.
Thanks for your help. Robert
