> EpubParser: mark the cover image as a THUMBNAIL embedded resource
> -----------------------------------------------------------------
>
> Key: TIKA-4852
> URL: https://issues.apache.org/jira/browse/TIKA-4852
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Reporter: Dominik Schmidt
> Assignee: Tilman Hausherr
> Priority: Major
> Fix For: 4.1.0
>
>
> EpubParser emits every image of the package as an untyped embedded document,
> in manifest order. The OPF names the cover, though: EPUB 3 via
> properties="cover-image" on the manifest item, EPUB 2 via <meta name="cover"
> content="<item id>"/>. Neither is read (OPFParser has no notion of a cover),
> so a client that wants the representative image of an EPUB has to guess.
> Proposal: resolve the cover item from the OPF (properties first, then the
> meta fallback) and emit it with tk:embedded-resource-type=THUMBNAIL, like the
> preview image of the other container formats (ODF, OOXML, iWork, GeoGebra,
> audio cover art as of TIKA-4850). Other images keep their current handling.
