We'll move to <#794206170445119489> but how did you encode them?
2025-12-13 07:56:46
For those images you probably want lossless, so try `-d 0` too

jxl was actually designed very much for 20x20 pixel art (not exclusively of course)

JPEG might not actually be illegal in that case
2026-01-20 09:37:36
JXL almost certainly would be

Some things might work but the HF coeffs likely would fail 0x130000
2026-01-20 09:39:39
which is most of the file

now I am wondering how hard it would be to make a valid jxl file that is almost all valid ascii
2026-01-20 09:54:53
(and also a reasonable representation of some input image)

was referring to the video "what happens if you open a jpeg in a text editor"
veluca now I am wondering how hard it would be to make a valid jxl file that is almost all valid ascii
2026-01-20 09:55:47
almost all, so basically not 0xff ?
veluca
2026-01-20 09:56:32
ideally
2026-01-20 09:56:33
😄
2026-01-20 09:56:38
0xff followed by ascii
2026-01-20 09:57:10
but probably the size header would need to be something else, and presumably some huffman tables too
Traneptora
2026-01-20 09:57:17
0xff unfortunately is never valid for UTF-8. or fortunately since it immediately rules out text
veluca
2026-01-20 09:57:34
yeah that was done on purpose
2026-01-20 09:58:02
(and also the 0x0a that follows, to detect confusion with windows and text mode)
Traneptora
 veluca 0xff followed by ascii
2026-01-20 10:01:01
all printable?
2026-01-20 10:01:24
i.e. between 32 and 126, not counting some stuff like 10
veluca
2026-01-20 10:01:33
sure why not
Traneptora
 veluca (and also the 0x0a that follows, to detect confusion with windows and text mode)
2026-01-20 10:02:24
wait that's why? so it immediately becomes obvious if you see 0xff 0d 0a?
veluca
2026-01-20 10:02:49
well, it fails the signature check
2026-01-20 10:02:56
but IIRC yes
Traneptora
2026-01-20 10:02:56

idea for compression: create textures for all things (stone, rock, grass, sand etc.) and then use AI™ to detect and replace them with a premade generic tile for maximum efficency <:galaxybrain:821831336372338729> /s

i feel like that's kinda what vae encoding is
2026-02-03 01:31:18
says the sort of thing that's in an area at a low resolution, and then it's up to the vae decoder to figure out what the actual pixels look like

At one point I considered a styistic quadtree project that would create boxes around alpha cutout things, but I putting it over a solid image just based on detail is so interesting
