2024-10-09 06:09:16 FAQ: What is JPEG XL? JPEG XL is a new image format with unrivaled file sizes. JPEG XL files are on average 40-50% larger than their PNG counterparts. It even has a special JPEG decompression mode that can make most common JPEG files 15-20% larger with no quality gains. /s

2024-10-24 03:17:05 i don't quite understand the question, where is ``` if (distance > 0.f && distance < 0.01f) { distance = 0.01f; }```?

2024-10-24 08:59:23 what question, or do you mean code?

2025-05-02 12:28:35 Hmm anyway to make it work on browsers?
DaKarma
2025-05-02 10:19:41 I think there is something like a mozilla firefox plugin, and one of them supports jpeg xl, saw that in a WaterFox review recently, I think you can probably find a way to add this plugin to other firefox based browsers
𝕰𝖒𝖗𝖊
2025-05-02 02:01:13 firefox based browsers already support JXL without plugins
DaKarma
2025-05-02 02:02:25 oh i thought it wasn't the case yet

2025-05-02 02:04:46 there's more nuance then that. Firefox does not support JXL while Firefox Nightly has really basic support that's off by default, and some forks of Firefox have full JXL support that's enabled by default
JesusGod-Pope666.Info
2025-05-02 11:36:15 What forks?
Dr. Taco
2025-05-03 01:47:09 Waterfox does, switched to it a few weeks ago when FF started selling user data. It's literally just "better firefox". highly recommend

2025-05-03 01:58:37 Waterfox okay.

2025-05-03 04:49:11 zen browser also supports jxl

2026-02-10 06:10:50 There is now a matrix space at `#jxl:bundernet.org`, for people who want someplace other than Discord to talk about JXL.
derberg🛘
2026-02-10 06:21:43 Huh, wasn't there `#jxl:matrix.org` before? However, only for the jxl channel afaik. But a space on some other domain is to be preferred anyways Btw. is there going to be a bridge? Like out-of-your-element, mautrix or patched matrix-appservice-discord?

2026-02-10 07:12:39 There was, but I think it was closed due to bot spam

2026-02-10 07:17:01 I think the API changed or something and it stopped working

2026-02-11 05:28:04 Apparently a bunch of new moderation options have been added to Matrix within the last year. Most namely policy servers, which can prevent that filtered messages reach rooms. Also hma-matrix can filter out already seen or slightly modified media.
