Hi, thanks for filing the bug.

What you're seeing is artifacts in symbol mode, since we can only use two colors per cell. For some images you can get better results if you specify --color-extractor median. This should result in less blurring, but potentially more noise instead.

I issus tmux
tmux/tmux#3395

[hpjansson]

If the issue is that you're getting symbol mode in tmux, that's unfortunately due to tmux not supporting images. There's nothing we can do about that in Chafa, unfortunately.

There is a sixel-capable fork of tmux, maybe you'll have some luck with that: https://github.com/csdvrx/tmux

Then to get sixel output in Chafa, use chafa -f sixel.

@newyorkthink Ping -- did you manage to fix your issue?

[newyorkthink]

I sorry , i have not time to find question. and not fix it

I see. I'm sorry, it's not possible to produce better quality inside tmux. This can only be improved in tmux itself. You must either avoid tmux or use a tmux fork with image support (for instance, the sixel-capable fork I linked to above).

I'll close this now. Feel free to reopen if the situation changes, or open another issue if you have other questions/bugs to report. Thanks.

Just to give my 2 cents feedback.

This is not a request, nor a demand for attention to this issue !

Just some curious fact to report.

I am a very big fan of chafa and I am perfectly satisfied with what it does and what it does not. I'm not a programmer, but I am well aware of all the constraints that tmux imposes

And yet "timg" was in the same "situation" and they somehow "managed" to overcome this, hzeller/timg#95

That is "timg" inside tmux inside kitty can see perfect images.

timg --pixelation=kitty cruZ6cSl_o.jpg

This is working as on my Archlinux system,

$ timg --version

timg 1.5.2+  <https://timg.sh/>

$ kitty --version

kitty 0.29.2 created by Kovid Goyal

$ tmux -V

tmux 3.3a

But,

chafa -f kitty cruZ6cSl_o.jpg

fails (that is chafa running inside tmux inside kitty)

$ chafa --version

Chafa version 1.12.4

Another one that, just like chafa, doesnt manage to do it inside tmux is "viu" , atanunq/viu#104

[hpjansson]

@m040601 Looks like the feature was introduced some time after I closed this. We should be able to support it without too much trouble.

I'll open a new issue to track it - thanks for bringing it up!
