Quote:
To make sure my fonts are recognized, Apple now requires this line instead of the com.apple.ibooks.metadata.plist file:
<meta property="ibooks:specified-fonts">true</meta>
|
In any case, if you like to be iBooks compatible I think it's better to add the meta tag and the package prefix
Code:
prefix="rendition: http://www.idpf.org/vocab/rendition/# ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/"
since there are other meta tags iBooks needs like:
Code:
<meta property="ibooks:iphone-orientation-lock">none</meta>
<meta property="ibooks:ipad-orientation-lock">none</meta>
<meta property="ibooks:binding">false</meta>
<meta property="rendition:layout">pre-paginated</meta>
<meta property="rendition:spread">auto</meta>
<meta property="rendition:orientation">auto</meta>
