In terms of reversible color transforms, we don't have direct transforms for N channels, but we can chain multiple transforms in arbitrary ways to construct "composite" color transforms that cover...

I forgot I already opened a similar issue: https://github.com/libjxl/libjxl/issues/477 Some more ideas are there. Closing that one though, one issue is enough.

Did you try other compilers or other versions of gcc? It could be a compiler performance bug...

Yes, it's a lot of unnecessary code duplication; I think it would make more sense to drop the libjpeg dependency and use our own jpeg parsing code for everything (currently...

Hm, strange, seems like compared to current git main branch, this doesn't really give much of a speedup at all anymore: Before: 3072 x 2048, geomean: 39.96 MP/s [29.81, 41.69],...

We kind of intentionally didn't include all options in the manpages yet because some of those are only meant for experimentation and might not make it into the final versions...

An ICC profile defines the color space of the pixels, including the transfer function. By default, cjxl will preserve the ICC profile exactly when doing lossless, while when doing lossy,...

I guess the main problem is this: ``` ./lib/jxl/enc_color_management.cc:1076: JXL_ERROR: Failed to make RGB_0.345985;0.360691_0.711098;0.288564;0.177004;0.822111;0.158514;-0.000808_Rel_TF? usable as a color transform destination ``` @sboukortt any idea what's going on here?

I can see a small difference between those two decoded images when I magnify enough, but I have no reason to assume that the libjxl decode is 'worse' than the...
