reading from novelai image not working?

[Weroxig]

test image: https://desu-usergeneratedcontent.xyz/g/image/1712/50/1712500928517.png
works on https://novelai.net/inspect but doesn't work on this tool for me.

This is incredible! There's no metadata in this image, but NovelAI's tool can still display the prompt.
My guess is when you use NovelAI to generate a image, NovelAI records the checksum of the image, along with its metadata, and provides a image without any metadata for you to download. When you use NovelAI's tools to recognise metadata, it will query the server's records. Therefore, I won't be able to retrieve this metadata locally.

They store information in the alpha channel

This is very interesting; I will try to add it to the parser in the next release.

Please try the new beta version, I have added a new parser for novelai.

Found on Redit also this style but the images are in webp: https://preview.redd.it/whats-that-something-furry-is-approaching-v0-drna37hcb9vc1.png?width=1080&crop=smart&auto=webp&s=62c432623502f5050a30958aa30719c1386dd3d5
When a random image converter is taken and convert to png (RGBA),
the image information can be read by the same logic.

The image from this link might have been compressed, so novelai.net/inspect doesn't work. Do you still have the link to the original Reddit post?

maybe i got confused here with a image, this works for me:

Ok, I will add support for webp in beta2. I just didn't have any novelai samples in webp format before, so thank you so much for your sample.

[receyuki]

Beta2 is here! I've added support for webp, please help me test any new images you find.
