Uneven page numbers

[MPete]

I've noticed when I have a book with uneven numbers it forces an even number of pages (I guess to make it a complete book).

Is there a workaround to have uneven pages - I guess the first page can be a two page spread (ie no cover) otherwise can we end it on a two page spread and lock the last page flip revealing the blank back page?

Yes, there'll always be an additional page added to make the total number even (for technical reasons).

To work around that you can use the pagebackground (previously prepage and postpage), which is a container in which you can define ASUL elements which is positioned behind behind the pages, with its origins at the top left of the left page. So to add the inside of a virtual book cover to the left try this:

Code: (xml)

<book>
    <pagebackground>
        <box width="pagew" height="pageh" background="image(data/cover_front_inside.jpg)"/>
    </pagebackground>
</book>
