mods are asleep, post memes in JXL

BitSound, 4 months ago

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

We should all use jxl and force people to support it

baduhai, 4 months ago

Works for me on Eternity for Lemmy on Android 13.

Malix, 4 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

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

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

SnotFlickerman, 4 months ago

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

ace, 4 months ago

Here’s a .jxl JPEG-XL upload I did on Lemmy three days ago;

image embed

Pyroglyph, 4 months ago

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

Octopus1348, 4 months ago

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

lars, 4 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?

Gallardo994, 4 months ago

Works in Cromite on android tho.

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

Octopus1348, 4 months ago

That “people who forget the terminator” post approves

gregorum, 4 months ago

Loads fine on Mlem on my iPhone

theherk, 4 months ago

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

moon, 4 months ago

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

Max_P, 4 months ago

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.

aBundleOfFerrets, 4 months ago

Firefox jxl support is restricted to nightly

panja, 4 months ago

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

prettybunnys, 4 months ago

Huh.

Memmy on my iPhone just shows it

aeharding, 4 months ago

Yeah jxl is fully supported on iOS

rubythulhu, 4 months ago

that still contradicts pictrs breaking the thumbnail

aeharding, 4 months ago

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

ace, 4 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.

pivot_root, 4 months ago

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.

juliebean, 4 months ago

i don’t want to go to all that effort. if you feel like it, could you describe it?

s12, 4 months ago

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

pivot_root, 4 months ago

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

Image DescriptionIt’s the King of the Hill https://knowyourmeme.com/memes/if-those-kids-could-read-theyd-be-very-upset, with the piece of paper saying “JPEG XL memes” and the kids in the classroom being labeled “Android users”.

Deebster, 4 months ago

Almost full marks,

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

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
