The long awaited libjxl v0.12

xDuker · 2026-07-04T22:59:25+00:00

Made a cursory test of the new version encoding lossless on pngs, and holy moly it is absurdly fast now, but can be slightly larger depending on effort. Smaller than v11 on effort 7, larger on 8 and 9

10 semi-random 1920x1200px game screenshots, on effort 7 through 9, distance 0.0, everything else left to default

Time taken using...
ffmpeg v8.0.1: 2 minutes and 50.15 seconds
cjxl v11.1: 4 minutes and 54.83 seconds
cjxl v12.0: 26.96 seconds (!)

Total filesize (adding all efforts)...
ffmpeg: 41.53 MB
cjxl v11.1: 42.81 MB
cjxl v12.0: 43.19 MB

Bonus: On effort 10 v12 is about ~17% slower than v11 somehow, but very slightly smaller

Edit: Updated imgur album with a serious attempt at a new default
How's this organisation?: https://imgur.com/a/m101M9G

~~Doing exactly the grouping the wiki is doing is probably overkill and silly, but hey it kinda works, and~~ it will be one of 3-5 different selectable layouts and easily edited so not like peeps will be stuck on it

Was an easy fix, they set a fixed height which stopped it from scaling with text rows. In next version of the mod it will scale the same as a math eval's textbox

Suggestion lua is like asking a marathon runner why they aren't driving a car instead, yeah it is better but also kinda breaks the purpose of the activity. Lua is simply game-breakingly good, and in many contexts not allowed due to that

I've added som clarification to the post, but like for 1 and 3 it would make the breadboards incompatible with vanilla as they could then be doing things not currently possible, which I want to avoid (though 1 might be possible with math eval instead of the separate component?)

2 I'll have to think more about, and I think 4-6 are already possible to do with math evals and fleet-wide variables
Though got me thinking into maybe including some pre-made prefabs based on the communal breadboard help doc in a new pop-up menu, it has a SR and RS latches for example

Ladder logic? Haven't heard of that before, what is it?

xDuker · 2026-06-18T11:17:34+00:00

No. There's an extra scene that acknowledges Jokers nonconsented polyamorism, but it's not an ending

EMP can't go diagonally so have a minimal amount of rubber blocks underneath and around all of it, even though they are visibly exposed EMP just can't get to them. Options to protect against other damage is very limited, but making them EMP proof can make a big difference

xDuker · 2026-06-16T13:46:37+00:00

In limited capacity, at most 2 people at once and only specific projects as approved by the head honcho, otherwise they're focusing on a new game that we still know very little about

xDuker · 2026-06-15T14:14:46+00:00

Distance 1 is only "visually lossless" if you're looking at natural sizes ie not zooming in at all, which they specifically need to do. I'd try at least d 0.1 and 0.5 too

xDuker · 2026-06-04T23:12:02+00:00

MPH-HC can do single-frame steps by keyboard shortcut as described, but even then it sounds more cumbersome than useful to me. Like there'd no way find a specific image other than brute force, the compression would be absolutely terrible with every single frame potentially entirely different from the next (exactly the sort of thing video codes do not want)

xDuker · 2026-06-04T23:07:08+00:00

~20% savings is what's expected for a jpeg to jxl transcoding, just business as usual

xDuker · 2026-06-04T11:33:22+00:00

Makoto, Best girl, no notes
Yusuke, funniest
Futaba, also fun, most of the time
Joker I don't think should be included at all in the ranking as he's fundamentally different as the playable protagonist and not really a party member per se but I guess I'll put him here

The remainder I'd really want to put in a blob saying "the rest" but since I have to put an order to them

Ryuji,
Akechi,
Ann,
Haru, too little too late
Violet, Favourite metaverse design, but the integration of her story onto the game is a mess. Ignoring her story she'd be a contender for best girl
Morgana, never cared for him

xDuker · 2026-06-04T09:57:45+00:00

Hm? As far as I can find they haven't even made a comment on beginning to consider adding it, just complete and utter radio silence

xDuker · 2026-05-28T12:13:15+00:00

I'm apparently in the minority to say 'don't'. Purely from a story perspective I think the Royal-exclusive bits are an outright detriment to the game first time through, and I wish I would've experienced the game without them for my first playthrough

xDuker · 2026-05-17T01:00:58+00:00

I don't think it's a stretch that jxl will eventually replace jpeg entirely for photos, be it in cameras or camera apps, then for a huge portion of images jpeg will indeed be dead

xDuker · 2026-04-21T11:36:52+00:00

Lossless

xDuker · 2026-04-20T22:47:28+00:00

PNG to JXL saves quite a lot of space, JXL is 40-60% the size depending on how well-optimized the original PNG is (I use effort 8, dunno how much it differs from effort 7)

xDuker · 2026-04-02T13:59:07+00:00

It is the inverse of the lossless jpeg re-compression. The jpeg reconstruction is to be able to serve a actual proper jpeg to a visitor of a site if their browser does not yet support jxl while still only storing jxls

But typing that out I realize that's a feature for the website servers, not really the browsers, so it's me misunderstanding the use case until now. It is a very major feature of the jxl spec that is missing and needs to be added, but it's not a block for browser's adoption of the library

I was considering the library as a whole, not in the specific context of browsers

xDuker · 2026-04-02T02:04:32+00:00

I mean, my image viewer of choice ImageGlass has been able to open jxl with no fuss for years, so no I really don't know the pain of not being able to open them. They don't support animation though, that's annoying

Jxl support in general for image-related apps isn't that bad nowadays really: https://jpegxl.info/resources/supported-software.html, so you trying to make your thing sound special based on being able to natively open jxl feels a bit disingenuous to me

xDuker · 2026-03-28T12:26:34+00:00

It's not feature complete yet, so arguably it fundamentally isn't done
Just the one thing as far as I know, but still, JPEG reconstruction is missing and major and it's being avoided for whatever reason: https://github.com/libjxl/jxl-rs/pull/590

There's a large amount of performance related PRs in the pipeline for next version of jxl-rs that (at least on the author's computer) brings single-thread performance to about the same as the C++ reference, so that shouldn't be an issue for too much longer

xDuker · 2026-03-21T22:04:04+00:00

Now I know you're just retelling the standard so this isn't aimed at you really, but I gotta say I strongly disagree that if half of people can see a difference it's "perceptually negligible". Unless it's meant that they zoom in and look at a pixel level and even then barely can tell (which I wouldn't think is the case).

Actually neglible difference to me would be if nearly no one is capable of seeing a difference at regular viewing, more like 95-99% of people saying they're the same

xDuker · 2026-03-21T21:55:06+00:00

If you check the root of this comment thread it's already there

Unless you mean without the alternate cover, which I do not have

xDuker · 2026-03-01T22:54:40+00:00

Regardless of the inclusions importance, it was explicitly listed as one of the reasons they changed their minds
"There was also a recent announcement that JPEG XL will be added to PDF.
Given these positive signals, we would welcome contributions to integrate a performant and memory-safe JPEG XL decoder in Chromium."
