Hi Calibre community !
I'm new to to world of ebooks, and I try to publish
my first comic as an ebook...
I'm also a Linux user, so I created a really simple bash script to convert a serie of jpg files to a CBZ file and then an ePUB :
zip $joinedfilename.cbz *.jpg
ebook-convert $joinedfilename.cbz $joinedfilename.epub --authors "$creator" --publisher "$creator" --title "$title" --isbn "$ebookIsbn" --pubdate "$pubDate" --no-default-epub-cover --dont-grayscale --keep-aspect-ratio
And It work like a charm, thanks to Calibre !
but I discovered today than Amazon want more metadatas :
"Error Description :Your book content appears to be fixed-format layout, but it is missing a fixed-format metadata tag. Please consult sections 4.1 and 5.1 of
the Kindle Publishing Guidelines to determine the best formatting choice for your content."
So, it's required I add

:
<meta property="rendition:layout">pre-paginated</meta>
and
<meta name="original-resolution" content="584x754"/>
to my epub ...
But with ebook-convert and ebook-meta, I can't find a way to add them...
I can edit the ebook withe the graphical client, but I'd like to automate the process...
Any Idea ?
Thanks a lot in advance !
