Manga double page

dem1980fr · 08-14-2020, 04:28 AM

Hello,

i have some manga that are double page.
That means, i have both pages in the same picture in my CBZ.
For example :
- image 1.jpg : [PAGE2 PAGE1]
- image 2.jpg : [PAGE4 PAGE3]
- image 3.jpg : [PAGE6 PAGE5]
Because in manga, the first page is on the right instead of the left.

I am reading with my Kobo Libra in portait mode.
When using the zoom with 'width of the page' or 'width of the content', the zoom in 'auto' (not 'semi auto' or 'manual'), in 'page mode' (not 'continue mode'), when i open the book, KOreader displays :
- the left of the image (image 1 / PAGE2)
- when i change page, it displays the right of the image (image 1 / PAGE1)
- when i change page, it displays the left of the next image (image 2 / PAGE4)
- when i change page, it displays the right of the image (image 2 / PAGE3)
The fact that the zoom displays the left then the right of the same image is very smart, but not with manga.

There is a setting to indicate at KOreader that the current book is a manga, so the zoom will display first the right of the image, then the left ?

Thank you

In the bottom menu, there should be entry where you can select "RTL" (standing for Right To Left). Unfortunately it still won't fix your problem. It's a bug that's already reported in https://github.com/koreader/koreader/issues/6270

Thank you, this option seems to work.

But the option "Wrtiting direction" cannot be changed, the option is grayed out when i open a cbz or pdf, and the option is hidden for an epub.
When i do a long press on RTL, i set this option by default, then i close my manga and i open it again and the option "Writing direction" is set top RTL.
It is very strange that this option can not be changed while reading the cbz/pdf.

RTL is used by crengine (the engine used in reflowable formats like epub and fb2).

Pdfs, djvu, cbz, etc are not reflowable and use another engine. I'm not sure if setting RTL does something on mupdf/dvju documents, but certainly not what you'd expect (right to left pages, or zoom according to RTL layout).

RTL in cbz change the order of the page for me

Writing direction is a setting for reflow. Reflow results on a comic/manga would probably range from nothing to undesirable.
