downloads from Comic-Walker are super small

Hi! :)

I think I've set everything up correctly, but the program downloads super small images regardless of the chosen file format. Do you think this is something that can be fixed?

The manga I wanted to download is this one, but it happens with every chapter and every manga:

Since this isn't a bug per se, jvm_log.txt is empty.

Cheers and thanks for doing this - I appreciate it a lot!

I just checked, unfortunatly it’s not a bug of the program, the images on their server are indeed of that small size.

This is for example the JSON returned by their API about the chapter 74 of that manga:

As you can see, the images size is just 650 x 923 pixels

In other words, this is the largest available size of this manga’s pages and, putting aside miracles, no amount of tinkering and assorted computer magic will conjure larger files? Damn, I’d swear the pages seem larger when I’m using their reader, but now that I think of it, the text seems to be a bit smeared, so I guess they really are this small… Oh well. Thank you for the reply!

There’s actually a way to achieve it. You can use Waifu2x, which uses deep learning and neural networks. It can enlarge images with small to none quality loss. I’d link it, but I’m not sure I can here. Just google it.

I just discovered that if you login into https://account.nicovideo.jp/ you’ll get a better resolution for the images. So in next versions I’ll insert the ability to login to get them in a better resolution
