Kitty graphic is color shifted for me (like RGB instead of BGR) #5
Description
Also, it doesn't seem to render 1px for 1px, there's a huge scaling involved.
This happens with both kitty and wezterm terminal.
My terminal (wezterm) emulates both kitty and iterm2 protocol to display images, but term.everything doesn't detect this. I can "force" kitty by running
TERM="xterm-kitty" ./term.everything thunderbird but I can't force iterm2 mode either.

Yep, I flip to bgr on purpose for the kitty editor:
term.everything/c_interop/src/ChafaInfo.cpp
Line 11 in f8c8527
On my system while using kitty it requires the bgr flip. But, I guess I need an exception for code that is kitty compatible, but not actually kitty term.

Hmmm. You should only have to specify the correct input buffer format, and the effect should be the same in both symbols, sixels and kitty modes. Chafa should take it from there.
Could this be a bug in your terminal, @mmulet? Are you both on little-endian systems?
mmulet commentedon Sep 11, 2025
I will update kitty and see if it's fixed. I'm on plain old little-endian, (i9-13900K)

Nope, even on Kitty itself it's flipped. I'm using Wayland, BTW, not X11.

Sounds like we should investigate why you're getting different results on the same terminal (AFAIU @mmulet requires flip, but @X-Ryl669 does not). My first guess would be that the
texture_pixelsbuffer captured by term.everything can be in different formats, and the pixel format arg just has to match it correctly.mmulet commentedon Sep 11, 2025
I know on my machine at least, there was a difference in whether the host machine was running Wayland or x11 , (thus the
session_type_is_x11check). Maybe that has been fixed and there is no need to flip now?I have to do day job work now, I'll be back in a few hours.

Any word of this? I noticed that the red and blue colours were swapped in my terminal(kitty) and saw this issue, but it's been a while.
Would it be possible to just add a colour format selector option so that users can manually choose it themselves if whatever is default isn't right?

Also, here you say you swap to BGR on kitty, but this seems to be doing the opposite? Swapping the two results of that ternary operator fixes the issue for me.

Sorry, I've been really busy irl. I think the flag is a good workaround for now. I'll make sure that gets done today.

While not a fix, I added a work-aound in Beta release 0.5.4.
See the updated help.md for the new options to change the pixel mode (BGR,RGB,etc) so that it will work on your system.
I'm still interested in finding a real fix to this issue, so I'm keeping this issue open.
