Re: How to detect if epub has only image (more like a comic book in Japan)

Thanks Luc and sorry for reply so late.


Yeah, better ask IDPF directly. I have not found any epub vocabulary for that purpose yet.

Cheers,
Jeff

Hi,

This would better be an IDPF question as this can already be done in EPUB 3 as a profile.

For instance, an OPF meta element could declare an « only image EPUB FXL » (vocabulary to find) and an epubcheck control would verify that there is no displayed text.
To be  analysed more deeply...

For us at Hachette Livre, as we produce many EPUB3 of that kind, this is a question we also have, and through EPUB AHL working group, we thought also that it was a better solution to use HTML in spine instead of just images.

Would you ask your question to the IDPF epub working group?

Best,
Luc

Hey


Wondering is there any way (specification? some potential epub element in opf?) to detect if epub only has image(or only image displayed) without layout the html?


Use case:

   Many Japanese comic only use image. So for this type of book, can use some different approach (comparing with fixed layout book with canvas or reflow book) to display it for some reason.

   But sometime creator also add some text with display:none to add kind of information inside book, so we can not force creator just use image in opf instead of using html.


Cheers,

Jeff
