Is it possible to embed PDFs in EPUB? - Page 2

adv_dp_fan · 04-18-2011, 11:30 AM

Apple's Asset Guide for the iBookstore has a section on embedding PDFs in an epub. Basically they say use an HREF linking an image to the PDF. When the image is tapped it opens the PDF in a separate view that has zoom controls.

They warn that overall maximum book size is 2GB and to keep that in mind.

And of course this is for iBooks, other epub viewers may not support the PDF.

The iBookstore Asset Guide says this will work.

When the image is clicked, it will open the PDF up in a new window with zoom controls. Has anyone tried this yet?

Would be nice if it worked on other readers too.

Just to update, I tried this and it works. Make sure you declare the PDF in the content.opf file or else when you click your link, it just jumps to the beginning of the book.

A couple things I noticed:

It makes the height of the PDF take up the entire screen. So if your PDF is landscape, the height will fit, but you have to scroll left to right. I'm using this for music tab PDFs, so it was a problem that they did not automatically fit in the screen. As a work around I re-did the PDFs so that are portrait sized, they just have more white space below. But at least they fit in the window when you click the,

Also what I am noticing is that large hi-res PDFs load very slow, making it hard to quickly zoom in and out and navigate. Low-res PDFs load fine, but look pretty bad when you zoom in on them.

I'll keep playing around to see if I can get settled on a certain size and resolution.

I'm trying to see if I can figure this out too. I notice that if you embed a PDF the EPUB doesn't validate. Something about hyperlinking to non-standard resources. This page seems to be explaining something about having a fallback method:

http://idpf.org/epub/20/spec/OPF_2.0...htm#Section2.0

It's over my head though. Anyone have a working example they could share? And any ideas if it'll work when the file's converted for Kindle?

I'm new at this stuff and probably shouldn't jump in so far over my head. It's fun though. :-)

Thanks, Phyllis
