Images from pixiv download as jpg instead of png

[nawj]

I found that when trying to edit a picture nekopaw downloaded that the image was a png and that nekopaw resaved it as a png meaning I have no idea whether these pictures were originally pngs without going through the rigamarole. Am I missing a setting where it's forcing this?

[catgirlfighter]

Can you give me an example of such image?

Warning, pretty much all of the linked images are NSFW

(https://my.mixtape.moe/ljsdzd.png image as downloaded with nekopaw) edit: mixtape automatically changed it to a .png after upload, so did imgur, so here is just an ss of files in the folder I downloaded to: https://my.mixtape.moe/bkinjt.png Everything downloaded in .jpg https://my.mixtape.moe/spxxif.png result of trying to open it in photoshop https://my.mixtape.moe/wequas.png opens fine in photoshop after changing the extension to .png

Also nekopaw ended up downloading just tons of duplicates https://my.mixtape.moe/iemobj.png but I scraped something that had a ton of images, I don't know if it was because it was such a large operation or if there were a bunch of duplicates in a bunch of different collections.

I required an URL on pixiv so I can test it, not actual pictures. I can't test it on already downloaded picture :)

Found a hint on last screenshot, I'll use it.

Something weird going on with your download. Used "Source: User works" without User ID checked (i.e. user id in tags). Found this: Downloaded an album 52820069. Got this: Windows Explorer, Firefox, Paint, GIMP say it's JPEG, all the same.

As well as it didn't give me duplicates. Did you download it more then once? If you can, please give me a full sequence of actions (mostly I need your set of presets for pixiv you used for search.

Oh, right, it's not an album that had a problem, I'm an idiot >< Basically, I need you to give me direct links to pictures, so I can actually test it on my side.

Alright, I just used Nekopaw to download this image, NSFW http://www.pixiv.net/member_illust.php?mode=medium&illust_id=58921137 Image is a .png:http://i2.pixiv.net/img-original/img/2016/09/11/05/12/50/58921137_p0.png Caps of me downloading it with Nekopaw: https://my.mixtape.moe/ubvpnb.png https://my.mixtape.moe/qrgbyd.png Result file: https://my.mixtape.moe/jmfhah.png

Again, sorry for taking so long to reply. After I made a clusterfuck of a response to you on your git and making an ass out of myself I was kind of embarrassed and I forgot about it.

[catgirlfighter]

It's OK, it's not like I'm fast to respond anyway. Confirmed it. It really uses jpg extension when it original extension is PNG, and pictures real extension is PNG.

[catgirlfighter]

Should work now.

Still having the problem after the update, with both single and gallery downloads. Tested with author ID: 14776527

[catgirlfighter]

Be more specific. Picture 58921137 downloaded as PNG correctly for me. Please give me actual pictures, verifying every single picture quite troublesome :/

[JarieSuisen]

That's awkward... since that very image is a JPG on my download. The program even identifies the original on Pixiv as being JPG.

But when I try to open the file in PSPV, it says it's a bad JPG file, and if I change the extension to PNG, it's fine.

[catgirlfighter]

For pixiv grabber uses "uncertain" method, means it doesn't know beforehand, which extension picture gonna be. So if grabber finds a downloaded picture with the same name, despite different extension, grabber gonna think it was already downloaded. I.e. you should delete old files. I use "uncertain" method to avoid loading extra pages, which can weight as much as picture itself.

[JarieSuisen]

Ok, I see that working (hadn't thought about the extension check before downloading), but only for single images. Each gallery download is still having the problem, such as 56803295.

Addressing that issue:

Also nekopaw ended up downloading just tons of duplicates https://my.mixtape.moe/iemobj.png but I scraped something that had a ton of images, I don't know if it was because it was such a large operation or if there were a bunch of duplicates in a bunch of different collections.

I downloaded it once, tried to download it second time, but grabber ignored it. Does it mean you tried to download from a lot of different sources at the same time, and they crossed? If that so, you probably should add a duplicate filter, something like "post_url = post_url". Normal url=url doesn't apply because for pixiv it's impossible to know a right url beforehand (old pictures have a different format of URL).

Mangamode supposed to have original extensions =^= Guess they changed it afterwards. Fixed.

[JarieSuisen]

Whoo! Looks like it's working right!

I know it's off the topic, but what about the newer animations (うごいら)? It's still failing to download them. (ex: image 59183003)

[catgirlfighter]

Gonna look into it. As always donno, how much time it's gonna take.

I guess I fixed it (accidentally).
