Did anyone try to save images from bookwalker’s web browser-based viewer? It paints the images on a canvas. Tried calling toBlob and toDataURL, but got a SecurityError. I guess life isn’t that simple. :/ The JS code is too much of a mess for me to read.

Edit: Okay, whatever. I can right-click on the canvas element in Firefox’s DOM viewer and there‘s a copy option. I just need a way to set the canvas to the right size somehow.

Thank you very much
btw the native resolution is 840*1200? or should I change something in the reader?

I'm not sure what the exact native res. is, but the script takes the width and height variable provided by EBJ for each image to render it.

Just made it even easier, now you can download a range of pages (or all) really easily!
Click here to update/dl: Download (Using Grease/Tampermonkey)
And one more thing I noticed: The reader embeds an ID (most likely anti-DRM) into the final page of the volume, which I disable in this updated version (by making it completely transparent)

For ebookjapan I made a userscript: https://gist.github.com/chocolatkey/ad0c04b0768f5fcdd3ea3c6cb089b8b2
(if you don't know what userscripts are, download the tampermonkey extension for chrome and click here: https://gist.github.com/chocolatkey/ad0c04b0768f5fcdd3ea3c6cb089b8b2/raw/f02ae25839d3904a6f85e93dbfc120f234baaae6/EBookJapanRipper.user.js then click install). Once it's installed, go to their reader, and once the page is loaded hit shift+d on your keyboard then check the top right corner for a button. Press it and it will rip the currently visible pages at their "native" resolutions and download them to your pc (and then automatically go to the next page). Criticism accepted.
Happy late new year!

I updated the Renta script because they ditched their Flash reader recently so it works a bit different now. Requires Pillow package for Python. It might fail on some books so please report any issues.

I replaced ".py" file to your new script, however, it said that "The filename, directory name, or volume label syntax is incorrect." I do not why. XO

No, if you decrypt the response of get_drmdetail.asp using ebix and keydata using the decryption in OMD, you will receive a JSONArray size 8 which is not empty, but in hexadecimal.
I have set break point in __decrypt_detail in viewer_engine-8e-min.js, so I think it's correct.
I'm sorry, I might have a misunderstanding.
I want to know is, I want to know the key or how to decode a certain "Detail" in the response data from the "https://api.ebookjapan.jp/api/trunkif_br/get_drmdetail.asp".
Do you say "JSONArray size 8" is to show the things that is in the decrypted data?

Is not it a "https://api.ebookjapan.jp/api/trunkif_br/get_drmdata.asp"?
Previously, it had been there to contain the DRM release key.
After the change, now as empty JSONArray size 8 you say.
"https://api.ebookjapan.jp/api/trunkif_br/get_drmdetail.asp" is added to the place, I do not know the key to decrypt the data from the URL.
I believe that has been changed in this URL.

If you decrypt it using the decryption methode in the same class, you will receive a JSONArray size 8, but I don't know what to do with it.

OMD is no longer available in the recent changes.
Release key is deleted from the data that has been acquired up to now.
And,
"https://api.ebookjapan.jp/api/trunkif_br/get_drmdetail.asp"
This has been newly added.
I do not know how to decrypt the data from this URL.
Anyone or Nobody can decrypt the returning data from this URL?
I have a OMD source code.
So, I will be able to update the OMD if you can decrypt it.

Can anyone help me get manga from Animate Book Store to download properly? Every program I've used thus far has failed, for one reason or another.

I used nwjs with the Tieba Manga downloader Alpha.dw file, and it just infinitely loads. (http://i.imgur.com/M3YChAa.png)
I used nwjs with the Comic Walker downloader but got an error "Downloading configuration failed!"
I used Alphapholis Downloader but got this strange error: http://i.imgur.com/Gn54Ooe.png

Forgive me if I'm missing something obvious, but can someone help me figure this out? Thanks.

I just didn't need to use it for EBJ since December last year or so ^^
So any other suggestions how to DL from EBJ?
Or any other site with quality images that works with OMD or any other program?
nay, i resort to printscreening, which, when done properly, yields acceptable results. a lot more timeconsuming though.

I use OMD 0.1.16 and I'm unable to download from ebookjapan now, be it the samples or books I bought. It starts getting DRM data but after a few seconds switches down the list of possible sources. Did EBJ change theri security so OMD is not working anymore or is it just my problem?
If the problem is with OMD does anyone have a suggestion who to fix it? Or maybe another downloaded I can use.... or another e-book store that has descend image quality but makes it easier to save/rip individual images (using any other program if needed)?
the normal omd version didn't function since january this year. or did you have a fix and can't use it since just recently?

There's another "problem". Seems like CW switched to 1200px (from 2048) image height since this URL change. /sad

I can't be sure for every series but I checked 5 I follow and these all become 1200px.
They've also removed previous chapters (except for the first few). The actual links use to still work, not anymore.

I don't really want to fix this, but if someone wants to tackle it, maybe putting an iframe in the downloader that opens the reader could do the trick (I know it is a little more complicated than just that). Or grab the scrambled images some other way and just decode them.

I have reduced the downloader to a simple decoder. If someone manages to dump the scrambled files to HDD, this can be used to descramble them. Just drag and drop the jpg files and watch png files show up.

Gangan Online did the same thing a few weeks ago, I was able to sort of fix that and the same thing works here. The only problem is I don't know how to automate part of it so it needs some manual work. It's hashing something and adding that to all the URLs, I don't know what it's actually hashing but if you can get the URL of one image then you'll have the key and adding that to all the others will make it work like normal.

Or rather is there a different program which does work? if so please post it up. Thanks.

Side note tried Poligrafowicz one as well unfortunately fails to download that needs an update as well.

Readers enact their own resizing and compression though -- so the image you get will depend on both how the publisher created the ebook and then what the distributer/seller did with it. EBJ is one which seems to mostly offer you the image the publisher gave them for example, whereas kindle ebooks tend to go through substantial compression after they get handed to Amazon.
True, I found sokuyomi and niconico to be worst. kindle was the same until a while back, but dozen books i purchased last october to december seem to have drastically improved. I haven't been able to purchase anything from amazon since then, so I can't say what they're like now.

ebj, bookwalker, honto (to name a few) I've never really had that problem. though ebj seem to resize all their larger stuff to 1600px height. (e.g. most readers offer comic valkyrie at x1920px, but ebj's is x1600). maybe they keep paid books in their original resolution but only resize the free stuff. maybe someone bored can rip the sample of mikakunin v7 to check. still, very few publishers (i.e. ichijinsha) go beyond 1600px, so it's not really a problem. their lower res (mainly shueisha and older volumes) books are x1200.
I don't purchase much from ebj so i don't have enough samples to be 100% sure. I dislike how the ebj adds a white border to the one side of the page (i've even seem them crop a cover). i guess it's to fit their reader.

ebj are clearly the best for kodansha titles. I wouldn't say they are better for other publishers anymore, most seem to be pretty good these days.


Hm, the BookWalker software for the PC saves eBooks locally to the file system now (by default, AppData) as encrypted images, so anybody who has reverse engineering experience may be able to crack the decoding algorithm. Thought I'd put this out there.
The previous extractor for BW patched the log4net.dll file. it's has since doubled in size after the various updates (assuming because it's using some super encryption now)

It always had, I believe that's how the first ripper worked, because it didn't even need the program open, they've changed some code or keys or something apparently, so it doesn't work though, so we started using the hook into the actual app, then they've protected against that, so as of now, there's no way to rip them

Ack, after reading all these posts, I still don't know what works, can someone summerize what is currently working and what is not?

tl;dr: the answer isn't reader dependant.

Which readers have the highest resolution? Or are they all 1024?

I tried some samples from a random manga using mdmdmd's scripts for Sokuyomi and Renta, which were 1024, and screenshots from Honto's reader app and EBJ's browser viewer, which I could get up to ~2500, but that doesn't help much without knowing their native resolution.
resolutions depend on the publisher

tankoubons:
shueisha: are usually 1200px from all stores
kodansha: 1024px, except 1600px in ebj (dunno why lol)
kadokawa/square enix are usually 1600px though i've seen some 1080px wide
i have some ichijinsha books which are 2100px
other publishers have their own sizes too. generally the preview copies seem to reflect the book's quality

magazines are higher resolution (probably because they're larger physically?). 1600px seems the norm now

tl;dr: the answer isn't reader dependant.

Is there a way to extract images from plus.shonenjump.com reader?

the same guy that made omd had a script for that. but his website has been deleted to apparently avoid prosecution.
