Subject: Re: [docbook-apps] Epub2 and SVG

I am curious about other people's approach to using SVG in Epub2.
However, all the epub readers we have tried do a horrible job of rendering SVG. We have tried Nook for Android, Aldiko, Mantano, EZpdf, and Readium. Azardi is the only one that produces usable rendering.
Is the best option to convert to png and use that? That would be a shame.

From the EPUB 3 Best Practices book[1]; "EPUB 3 maintains compatibility with EPUB 2 through its continued use of SVG 1.1..."

Can you implement a fallback?

<object data="image01.svg" type="image/svg+xml" width="640" height="480">
<img src="image01.png" alt="..." />

"Using an object tag also allows you to embed a fallback image for those reading systems that don’t support SVG"

I've only just started looking into the DocBook XSL this last week but apparently O'Reilly made some useful additions to the EPUB3 stylesheets[2], making them fully EPUB2 compatible. You should also read EPUB Best Practices as you'll find a lot of useful information in it.
