JPEG-Archive 2.1.0
This release adds the ability to disable subsampling and updates the underlying mozjpeg library.
- Add the
--subsample
parameter which can be used with the valuedisable
to turn off subsampling. By default 4:2:0 mode is used (which subsamples chroma channels 2x1). Disabling it turns on 4:4:4 mode which may be desired for certain use-cases but is generally not required. - Update to the official mozjpeg 3.0 release. This provides an extra 1-2% compression advantage at the same encoding quality and speed.
- Set up Windows CI so that Windows users can always grab the latest binary from the Windows CI build server
