Pending on libgd/libgd#699
Allow WebP images to be converted into JPEG XL
Add method that uses system cjxl binary (installed with system package manager)
Right now Linux and Windows static binaries are daily builds rather than stable versions. Either wait for JPEG XL to release a new version or build the static binaries from version 0.5.0 source code.
@joppuyo I came here after running into & really liking your posts
Is WebP really better than JPEG? & What’s the best lossless image format? Comparing PNG, WebP, AVIF, and JPEG XL, & became impressed that you're developing on JXL. I'd really want to encourage you to update both (but especially the 1st) posts w/ your further JXL results.
Some ideas inspired by WebP Convert:
Allow lossless transcoding for JPEG input
This should be preferably be done once, on library instantiation to speed things up.
Add auto mode where both lossy and lossless compression are tried and the smallest file is chosen. This should be the default for JPEG files.
Add arm binaries for Linux and Mac
Allow setting timeout. This is currently 60 seconds which is symfony/process
default.
Right now lossless/modular mode is fixed to 100 quality. Need to figure out a good way to do this, it's weird if the modular is named lossless but it can produce lossy images.
Run system convert
in the command line.
