Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
a good day for jxl (libjxl v0.8.0, and exiv2 v0.27.6)
4 projects | /r/jpegxl | 18 Jan 2023
In addition, this commit isn't available in 0.27.6 yet, so newer JXLs which use Brotli to compress metadata (e.g. files encoded with libjxl 0.7.0) will also show no metadata unless you build exiv2 from the main branch with BMFF (and rebuild dependents of exiv2).4 projects | /r/jpegxl | 18 Jan 2023

Exif data from image file
2 projects | /r/golang | 4 Dec 2021
Thanks for the reply. I went a little bit deeper to get more out of images metadata using Exiv2/exiv2. It's getting everything from "exif" to "xmp" tags. And it's fairly maintained ! Only drawback, it's not written in GO. So I'm gonna call it using the cmdline ^^.

some of these appear to not actually have curated tasks. it lists exiv2 for example which links to an issues tag on github, but it's empty https://github.com/Exiv2/exiv2/issues?q=label%3A%22good+firs...
Issue link to DigiKam support for JPEG XL
2 projects | /r/jpegxl | 8 May 2021
"WebP has been supported since 2016. You're right. I should add JXL. We only need to add a few lines of code to support JXL/bmff. JXL/codestream is still being negotiated by the standards committee and will add ICC support. Exiv2 doesn't provide ICC support for every image format." https://github.com/Exiv2/exiv2/issues/1466
How do you install exiftools via command line?

exiv2 is a similar, but different program than exiftool.
Conditionally Batch Edit EXIF Header

Does jhead, exiftool, exiv2, etc., allow me to use a command or a series of commands to accomplish this goal?
Exiv2 now supports JXL/bmff
2 projects | /r/jpegxl | 3 Apr 2021
Great! Reading through issue 1503 though, this support is for EXIF and XMP data in the "container" version of the format. Support for an ICC profile in the "codestream" format (both bare files and inside a container format file) is in issue 1506 and left for future work. So the support is not complete, but a good step forward for the format.2 projects | /r/jpegxl | 3 Apr 2021
