Still early days. Some things work, some things don't.
I've detailed what I know about the LRI format in LRI.md. Details about a weird format they use called Bayer JPEG described in bayer_jpeg.md.
A friend archived a lot of Light L16 stuff at helloavo/Light-L16-Archive. Notably it contains firmaware images, instructions for upgrading your firmware, root instructions, and a lot more! It was incredibly helpful.
A Rust crate for parsing LRI files. This library isn't perfect, but it works enough to be able to grab image data from the files.
The code here is a mess, but I'm working to improve it. Reading the metadata from the LRI files is weird! It's all in protobuf messages and those protobuf messages make a lot or stuff "optional". We end up with a lot of duplicated data
Breaks an LRI into the individual images it contains
prism <lri> <output_directory>
TODO: I'd like to, one day, be able to write DNG files from prism, but currently it just spits out PNG.
This is a gently modified version of the dllu/lri-rs repository. Without the work from Daniel pulling the protobuf definitions from the Lumen software I truly don't know if I could've got as far as I did.

Run with the arguments gather <path> to print information about the LRI files in the directory to stdout.
This was very useful to me while developing lri-rs to be able to see if patterns repeated across many different images so I could make some assumptions.
