No docs for paletteuse filter option "dither=none"
|Reported by:||jason||Owned by:|
|Blocking:||Reproduced by developer:||no|
|Analyzed by developer:||no|
The docs for paletteuse list "bayer", "heckbert", "floyd_steinberg", "sierra2", and "sierra2_4a" as acceptable values for "dither", with no documented option for disabling dithering entirely.
However, the filter appears to accept "none" as an option to disable dithering, at least in:
- Whatever version the author of this answer was using in Nov 2020, as well as the author of the question there, and
- My version: 4.3.2-2021-02-27-full_build-www.gyan.dev (I didn't test on others).
It should probably be documented. However, I'm not sure if this is a documentation error vs. "none" not being a stable long-term option.
Does anybody know what version "dither=none" started being valid with, and whether or not it's intended to continue working in the foreseeable future? If it's an unstable or temporary feature, then it might not actually be a documentation error.
