This PR introduces support for encoding jpeg-xl, closes #11.
Since there's no yet support for
jxlinimage-rscurrent version temporary uses jpegxl-rs crate.Note, that since there's no rust-native
jxlencoder, this crate adds dependency forlibjxl. I think we may need to make this[feature]flag instead?Also, there are some options available for controlling
jxlencoder, such aslossless,quality,speed. We can make it configurable viaconfig.tomlfile, though do we really need to go that far? Right now encoder uses default settings, which createsvisualy losslessresults.One more thing to note, that this PR only adds ability for creating screenshot file as
jxl, for now, at least. Theclipboardandstdoutresult will be a simplejpeg. I am not sure if we should change this behavior, actually.
