Anyone knows if it's possible to dump manga pages from Crunchyroll in PNG instead of JPEG?
Currently, I'm using the following URI:
[code:lit]"encrypted_composed_image_url": "http://img1.ak.crunchyroll.com/i/croll_manga/e/XXX_main"[/code:lit]
but would like to try with:
[code:lit]"image_url": "http://img1.ak.crunchyroll.com/i/croll_manga/YYY.png"[/code:lit]
But it returns with 403 status (access denied).

On the same note, every page seems to have [code:lit]"is_spread": false[/code:lit], even those that are really spreads. Are there any other way to determine this?

What is the original format in chrunchy?

How is the image encrypted anyway?

There must be some sort of decryption routine in the flash.

Flash player renders composed JPEGs, I have no problem downloading and decrypting them. Here's a page JSON from their API:

**"image_url"** URL extension suggests PNG, but I wonder what those really are. By the way, page.image_url is clean, so international scanlators might find it useful.
>>
>>101325919
Guess:
page.image_url = clean page
page.enUs.image_url = only the translation
page.enUs.composed_Image_url = both of the above put together

You're probably right. Guess it's not a big deal, except when there's no composed page. I've encountered only one for whole series, though.
>>
>>101326311
The question is why you'd encounter a 403 for the TL, but not for the clean pages.
That doesn't appear to make much sense to me.

Is there are any reason why the clean pages need to be accessible to the public?

Older pages have bubble polygons defined in JSON, maybe CR wanted to deliver translation via text and draw it on the client side. We can only guess, anyway.

>xor 0x42
you could barely call that encryption
>>
>>101327128
wait op, I got it

Take image_url, add /e/ after /croll_manga/

So... http://img1.ak.crunchyroll.com/i/croll_manga/e/96378fd978f147c5c6fcbf0ffae7e156_1383743318_main.png

Transform with XOR 0x42 and pic related is the result

Awesome, now I can compose them and fix the page!

>>101327642
Will I experience any problems from Crunchyroll if I put my my dumper at Github?
>>
>>101327912
Yeah, they'll probably call github up for your ip so they can steal all the money from your bank account

no
