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.

png crate gets an ultrafast compression mode, up to 4x faster decompression
When the QOI format was first announced it wasn't clear that was even possible while keeping PNG format compatibility. But the fpng and fpnge C/C++ libraries showed it was, and today you can take advantage of those advances in a general purpose PNG library in Rust!

Hello, PNG
But most platforms these days have some form of CRC32 "acceleration". Adler32 is easy to compute so I'm even less concerned there.
I spent a bunch of time optimising the code in [fpnge](https://github.com/veluca93/fpnge), which is [often notably faster than fpng](https://github.com/nigeltao/qoir/blob/5671f584dcf84ddb71e28d...), yet checksum time is basically negligible.
Having said that, the double-checksum aspect of PNG does feel unnecessary.

The Near-Lossless Image Formats Using Ultra-Fast LZ Codecs
It's important to notice that ZPNG beats virtually all QOI variants, as discovered in: https://github.com/nigeltao/qoir

Quite OK Image is now my favorite asset format
* AFAIK it does this while beating the original QOI in terms of speed AND efficiency
Lots of benchmarks in: https://github.com/nigeltao/qoir
QOIX
QOIX is my very own version that adds:
What are some alternatives?
fpng - Super fast C++ .PNG writer/reader
CompactGUI - Transparently compress active games and programs using Windows 10/11 APIs
zpaqlpy - Compiles a zpaqlpy source file (a Python-subset) to a ZPAQ configuration file for usage with zpaqd
qoipond - Lossless image format inspired by QOI “Quite OK Image” format
php-qoi - QOI image encoder and decoder written in pure PHP
tinf - Tiny inflate library (inflate, gzip, zlib)
canvas_ity - A tiny, single-header <canvas>-like 2D rasterizer for C++
figlet-fonts - my collection of figlet / toilet ascii art fonts
Zpng - Better lossless compression than PNG with a simpler algorithm
