[QGIS-Developer] Planned support for JPEG XL?

[Bourdon, Jean-François (DIF)]

Hi Andrea,



I haven't as it wasn't an option when I sent my email, but now that it is, I'll do. If I understand the PR correctly, it will only be available with a gdal-dev install for now but I suppose that in a couple release it will be available with "regular" gdal by OSGeo4W and thus available to all QGIS Windows users by default.



Thanks

Hi Jean-François,

if you are using Windows OS and GDAL provided by OSGeo4W, have you tried to update GDAL to the latest GDAL 3.7.0-2 package which was build against libjxl?
