This customization layer for the DocBookXslStylesheets converts a DocBook document to html that can be viewed as a slide show in the Opera web browser.


When writing a DocBook document, use role="screen" to indicate elements that should only be displayed when viewing the page as regular html. This text diappears when viewing the page in full screen mode. Use role="presentation" on elements that should not appear when the page is viewed as regular html. Convert your DocBook document to html using the stylesheet below and your favorite xsl processor. Then view the page in Opera and press F11 to toggle full screen mode. For an example, see How to avoid learning XML. Also see this Operashow tutorial. Send questions to DavidCramer

<!-- This DocBook customization layer allows you to produce -->
<!-- an Operashow presentation. For more information about -->
<!-- Operashow, see -->
<!-- from DocBook using the html XSLs. Add role="screen" to -->
<!-- any element that you want to appear ONLY when viewed as -->
<!-- regular html. Use role="projection" on elements that -->
<!-- should appear ONLY in full screen mode. Currently it -->
<!-- supports role="screen" or role="projection" on block -->
<!-- level elements  -->

<!-- It's up to you to make sure that the text fits on the display at the -->
<!-- desired resolution. Currently, long slides end up -->
<!-- overlapping the next slide. I've been meaning to look -->
<!-- into seeing if there's a way to make it behave better -->
<!-- when this happens. -->
