I don’t know where is the right place to post this, but @Akashelia asked me for my script I use to download manga volumes from Bookwalker, this is the one I’m using to get freebies in a quality as close to native, it also works on the paid ones that you own and samplers of books
Set your page to a single spread, press download and here you go ^^
I kinda don’t want to maintain this one, because Bookwalker changed the method of interacting with the webpage between 1.3 and 2.01 and the script broke between then, but for as long as you can use it and download your books, you should be able to enjoy this one
(also, just in case, I have a version of Mokuro that’s updated for the newest dependencies and the version of Python, plus accelerated using mps for MacBooks if anyone was running one, I know that Mokuro is a project that’s managed by someone different though, so is it still in development? should i make a pull request to the main repo? how should I go around uploading it?)
EDIT: Also, since Akashelia was asking for this, I added a radio to determine the quality of the output: I parse all of the manga that I have in WebP because the PNG files are gigantic, but if you really want to preserve the native quality, PNG 1.0 quality has been added too:
