No Dither, Dither

` RNA_def_struct_sdna(srna, "ImageFormatData");`

Hi

We are adding JXL to blender

👀

I wish image viewers would accept any bit depth and dither it natively...

32bit IrfanView, Waterfox

8bit IrfanView, Waterfox

<:KekDog:805390049033191445>

of course they added the vaseline format

<@335432712875802624> what if you git blame that file?

Lossless is good though

yeah lol

true

just rewrite blender in rust first

also fair

it used to at one point

like a few years ago, but I heard gcc has been improving. it's worth trying though

Original: 102.03 MB PNG

Was it at WebPs max compression (z9)?

does lossless webp still suffer from being tv range or is that just lossy

just lossy has that issue

i can hear you by the way so you don't need to reply in text ^^ I just can't talk atm

oh yeah zig can use lines as compilation units right

you did it!

<@238552565619359744> do you remember what the option in djxl was to output the image with the block selection overlay? iirc that was fixed recently

oh lord

I do have the libjxl source code here, if it's like a flag I need to change that works

https://github.com/libjxl/libjxl/actions/runs/19247098217

https://github.com/libjxl/libjxl/blob/9174e635cd5980e96fcf50d37873cf40045ce2df/lib/jxl/enc_ac_strategy.cc#L55

thanks

i'll just change the source code, I was working on that anyway

`benchmark_xl --debug_image_dir ./ --output_dir ./ --save_compressed --skip_butteraugli --input Test.png --codec jxl:d1` Put the input in the same directory

https://github.com/libjxl/libjxl/pull/4516

I can't figure out how to make it output a block selection overlay now that `JXL_DEBUG_AC_STRATEGY` is set to `1`

is it some parameter in djxl that's not listed in the help menu?

<@384009621519597581>

oh my bad

https://cdn.discordapp.com/attachments/530853682678595594/1439890520695640064/RDT_20251117_0810254455623124819894205.jpg?ex=691c2a0c&is=691ad88c&hm=295ae061d7bea04595cc815139a3b14cdeaa4633be99f77cec1b1f55a88fec1d&

AI upscaled

Ouch

the output is black

`--patches 1`

that gives me four black ones instead

`benchmark_xl --debug_image_dir fav/out --output_dir fav/out --save_compressed --skip_butteraugli --input fav/045.png --codec jxl:d1 --patches 1`

it's still not annotated, I'm running the exact command you posted

just making sure, this is supposed to work when I just change `JXL_DEBUG_AC_STRATEGY` to `1` right?

no I'm using your exact command

I'm using the latest, I just cloned the repo

I wonder if some recent change broke it

I got it from the qoi benchmark set

I used it because it had some odd block selection in the paper

i'm doing a full recompile, maybe the incremental build didn't work well

wait

oh my god

it's using the system `benchmark_xl` instead of the one from the build folder...

I'm so sorry

it's working now

interestingly this isn't required in Chromium/Thorium. It is needed in Waterfox tho

Chromium's implementation of libjxl yet again showing it was one of the most competent ones in existence (probably because actual JXL devs worked on it)

for some reason the dithering is ordered again which is weird

but that's not a problem

Isn't that just because Chrome actually does color management, also Waterfox works fine

did you try that one old house picture?

ah the tennisser picture from the paper was scaled down so I can't replicate it exactly

for me it has the horrible banding in Waterfox although I am testing an old version so maybe that's why but idk what would have changed

alright I gotta dip, thanks for the help ^^

See ya
