Thanks for your reply.
I checked if the other Comic Input Option here (
http://manual.calibre-ebook.com/cli/...-input-options) work on azw3 and confirmed these options don't work on azw3. Thank you.
And from a web page (
http://jarp.does.notwork.org/diary/2....html#20130812 written in Japanese), I found what feature "right2left" option have and howto resolve the problem.
"right2left" option insert "page-progression-direction="rtl"" in <spin> tag on epub file.
Code:
$ unzip -p ebook.epub content.opf | sed 's/<spine/<spine page-progression-direction="rtl"/' > content.opf
$ zip ebook.epub content.opf
Above commands is described on the aforementioned page.
So I checked if "page-progression-direction="rtl"" exists in content.opf within epub which generated from azw3 and confirmed it exists, though I couldn't add "right2left" option. Strange...
Anyway, thank you.
