The lengths I had to go through to open this even on my Linux desktop. Wow.

  • pictrs failed to generate the thumbnail
  • The image crashes Firefox
  • Chromium shows a broken image icon
  • Gwenview says it can't load the metadata
  • Okular says it's an unsupported image format

I had to open the darn thing in GIMP lmao

E: one install of kimageformats5 later and Gwenview/Okular can open it fine. Firefox still refuses to open it even with image.jxl.enabled set to true.

Huh.

Memmy on my iPhone just shows it

[–] [email protected] 44 points 9 months ago (1 children)

Yeah jxl is fully supported on iOS

[–] [email protected] 3 points 9 months ago (1 children)

that still contradicts pictrs breaking the thumbnail

[–] [email protected] 9 points 9 months ago

I’m not sure what’s up with pictrs. I compressed this image with https://squoosh.app default settings if it helps.

As an Android user, OP's image was accurate.

  • My Lemmy app couldn't open it.
  • Chromium showed the broken image icon.
  • Firefox said it was broken.
  • Firefox Beta with the about:config flag for enabling JXL still said it was broken.
  • Gallery apps couldn't open it.
  • Renaming it to .jxl still didn't help.

I gave up and grabbed a JPEG XL viewer/converter just to see it.

It’s “JPEG xl is a superior image format that your device should support.”

[–] [email protected] 6 points 9 months ago (1 children)

I don't remember what it said exactly, but here's a rough description:

Image DescriptionIt's the King of the Hill if those kids could read they'd be very upset meme, with the piece of paper saying "JPEG XL memes" and the kids in the classroom being labeled "Android users".

[–] [email protected] 5 points 9 months ago

Almost full marks,

the paper saysJPEG XL is a superior image format that your device should support

[–] [email protected] 3 points 9 months ago

The built-in Firefox support is only activated for unstable builds, so you can't enable it on stable unless you manually enable it during compile-time.

[–] [email protected] 2 points 9 months ago

You have to have an extension to get jxl on Firefox and even then it's still buggy :)

[–] [email protected] 1 points 9 months ago

Firefox jxl support is restricted to nightly

[–] [email protected] 32 points 9 months ago (1 children)

I couldn't view this with Firefox or Gnome. ImageMagick to the rescue, though:

Lmao, I tought it was some instance issue (didn't read the title).

[–] [email protected] 6 points 9 months ago

We should all use jxl and force people to support it

c/programmerhumor is going to be the place where people go to try and break fediverse clients, isn't it?

[–] [email protected] 3 points 9 months ago

That "people who forget the terminator" post approves

[–] [email protected] 15 points 9 months ago (1 children)

Why is it .jpg and not .jxl? That's the registered extension for JPEG-XL.

[–] [email protected] 6 points 9 months ago (1 children)

I'm going to assume Lemmy doesn't allow native upload for jxl, but to fudge around it you can use jpg?

[–] [email protected] 10 points 9 months ago (2 children)
[–] [email protected] 4 points 9 months ago

I checked the headers and content and this checks out!

Does this mean there’s some way to upload an animated GIF that Lemmy won’t convert to a static format?

Interestingly, this JXL loads in Boost, but the one in the post doesn't. Perhaps it's because it's inside a comment?

[–] [email protected] 1 points 9 months ago* (last edited 9 months ago)

No, it's because this is actually named .jxl and not .jpg

[–] [email protected] 13 points 9 months ago

I'll upvote out of principal but fuck tryin to look at that shit lol

[–] [email protected] 9 points 9 months ago (1 children)

Loads fine on Mlem on my iPhone

[–] [email protected] 4 points 9 months ago

It is supported through the entire Apple product line in recent versions.

[–] [email protected] 9 points 9 months ago* (last edited 9 months ago)

Interesting, it struggles with the embedded image here on Lemmy, but when going to the image directly, I can see it fine.

Edit: OS: Windows 10 Pro / Browser: Firefox with JPEG-XL support enabled

[–] [email protected] 4 points 9 months ago

Works in Cromite on android tho.

[–] [email protected] 4 points 9 months ago

worked fine on my android phone, using Connect.

worked fine on firefox & linux, the file shows as .webp to me.

Decided to investigate this a bit: when opened to new window, the image url has ?format=webp query argument, if I change that to ?format=jxl then it breaks as the server actually provides a .jxl file. At least I had to TRY to break it :P

Loads by default for me on Firefox Android, and I can see the embed just fine.

[–] [email protected] 2 points 9 months ago

Works for me on Eternity for Lemmy on Android 13.
