calibre importing kobo books, foolish layout

Hello

Linux OpenSuse Leap 15.2
Calibre: 5.24.0
Kobo-desktop: 4.28.15823 installed with wine
DeDRM: 7.2.1
obokDeDRM '7.2.1'

I sum up the problem.

i bought this book

https://www.kobo.com/fr/fr/search?qu...cationDateDesc

I use calibre and obok plugin for importing this book.
There is no problem for obok removing the drm.
The problem is that obok( calibre ?) produces a book with a foolish layout.
ADE importing from kobo the same book, produces also a foolish layout!

I assume that the format of this ebook is a very special one.
At kobo site it is said "This ebook is a digital version of the paper guide without additional interactivity".
Perhaps this a beginning of an explanation.

I bought another book at kobo site which has a more standard format. There is no problem. drm is removed, and we get a good layout, thus a readable book.

I sent a report to dedrm team. They said it's not a dedrm problem.

Is it a calibre problem ?

see the dedrm report where i exlore the problem.

After this - "ADE importing from kobo the same book, produces also a foolish layout!", why do you thing it's Calibre or the DeDRM plugin problem, and not something wrong in the book structure ?

You should turn to Kobo or to the book publisher.

I did not well explain.

Using the kobo reader app, there is no problem to read the book.

There are two steps, importing a book in Calibre:
- removing the drm. This is made by the Obok plugin with success.
- create the book. This is made by Calibre. No ?

Then I assume Calibre does not recognize this special type of format.

I hope someone has a solution.

thanks

Calibre does not create the book. It copies the book into it's library with the optional DRM removal which does not change the book content or layout.

If you are trying to read a fixed layout epub3 ebook, calibre's viewer will not work well with it nor will your Kobo ereader unless you send it to your ereader as a .kepub.epub to trigger use of the epub3 renderer (.epub will use the Adobe RMSDK renderer). If you open the ebook in calibre's editor you can look for "<meta property="rendition:layout">pre-paginated</meta>".

I've attached a screenshot from a fixed layout epub opened in calibre's viewer.
