Merge cover and metadata in epub

[mpuech]

Hello,

I've modified the metadata of an epub.
So in the directory there is a cover.jpg, a metadata.opf and the epub file.
Is it possible to include the jpg and the opf in the epub ?

I use Calibre 1.25 with Ubuntu 14.

Regards,

They ARE already included in the .epub file.

Calibre keeps a copy of the cover for display in the GUI as not all formats support covers. The .opf file is kept to allow for recovery when/if the Main Calibre metadata database gets corrupted.

Thanks for your quick reply, but I'm not sure I was comprehensible (sorry I'm french).

I modified the comments and changed the cover at 21:21, but the epub last modification didn't change:
max@pc-max:~$ ls -l "/home/max/Bibliothèque calibre/Collectif/Guide d'autodefense numerique _ Tome 1 -- hors connexions (6973)"
-rw-rw-r-- 1 max max 56194 juin 21 21:43 cover.jpg
-rw-rw-r-- 1 max max 197242 juin 21 19:05 Guide d'autodefense numerique _ Tome 1 -- - Collectif.epub
-rw-rw-r-- 1 max max 3498 juin 21 21:43 metadata.opf

If I copy only the epub in another place, import it with Calibre, the comments and the cover aren't modified.

max@pc-max:~$ ls -l "/home/max/Bibliothèque calibre/Collectif/Guide d'autodefense numerique _ Tome 1 -- hors connexions (7029)"
-rw-rw-r-- 1 max max 12235 juin 21 21:51 cover.jpg
-rw-rw-r-- 1 max max 197242 juin 21 21:51 Guide d'autodefense numerique _ Tome 1 -- - Collectif.epub
-rw-rw-r-- 1 max max 3508 juin 21 21:54 metadata.opf

A the importation, Calibre created a cover.jpg and a metadata.opf from the epub (you're right, they are in the epub) but there are the old ones.
I would like to distribute the epub with the new cover and comments.

Of course, the epub is free (https://guide.boum.org/).

@mpuech - when you update metadata and/or cover the format files are NOT updated.

If you use Send to Device, or Save to Disk the copy of the format file sent or saved (e.g. the EPUB) will contain the current metadata and cover.

If you want to update the EPUB in the library with the current metadata and cover, the simplest way is to use the Polir des livres tool (press 'P', or add to toolbar).

Thanks a lot BetterRed, Polir des livres is what I was looking for!

I just have a warning:

Failed to initialize plugin: '/home/max/.config/calibre/plugins/KePub Metadata Writer.zip'

It's the 2.7.1 release and I also have "Set EPUB metadata" 1.25.0.

I'm not familiar with KePub Metadata Writer, its not in the optional plugin index, and I can't see it in the list of built-in plugins.

Why are you using such an old version of calibre - 1.25 was released in early 2014, there have been about 100 new versions since then? Latest versions are at ==>> calibre - Download calibre.

I don't know of a reason it wouldn't work. It is working with 3.0 and 1.48 on my Windows machine. I'd suggest removing it and installing it again.

@BR: KePub Metadata Writer is in the plugin index. It's the only metadata writer plugin.

Possible Python version (too low)

I suspect I tried to find 'keypub' in the index. I saw it when I was editing the index for Doitsu, but I had rush off to the Leichhardt Palace
