Announcing: ImageSieve, a tool to assist in sorting and archiving images and videos
I absolutely loved all the crates available that made my life very simple in many cases. I used (among others) the slint ui framework, kamadak-exif, img_hash, fast_image_resize and rawloader.

QOI: Lossless Image Compression in O(n) Time
The simplest form is just to pack 10 or 12 bit values. There's all kinds of variations of that:
https://github.com/pedrocr/rawloader/blob/a59bb78d156277781a...
There are a few formats that use a curve and less bits. They do become lossy and doing dithering on decompress is useful to avoid banding.
The Nikon one you mention was only used very early and is decoded by decode_8bit_wtable() in that file. It's just looking up the 8 bit value in the table and then adding some randomness to prevent the banding.
