Readium Supports EPUB 3 Fixed Layout Metadata
The Google Chrome browser extension has been updated to version 0.21, which includes basic support for standard EPUB 3 fixed layout metadata, as per samples available here. The initial implementation has several limitations, including that the fixed layout decision is made on a per book basis rather than per spine item, so it only works if fixed layout is specified globally via the rendition:layout metadata property. And, bugs, including that if both standard EPUB 3 fixed layout metadata and Apple's vendor extension to EPUB 2 are present in a publication, the Apple metadata is used in preference to the standard metadata. For details, see the Readium issue tracker on github.
