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.

CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
FTR there is a WebP decoder implementation in safe Rust in the image crate: https://github.com/image-rs/image
It used to be quite incomplete for a long time, but work last year has implemented many webp features. Chromium now has a policy of allowing the use of Rust dependencies, so maybe Chromium could start adopting it?

Porting a local app to Web
Hello! So I have a local app that I am currently running on desktop (windows). I'm using egui for the UI, and the program basically opens a folder, gets all the images in the folder, and then uses the image-rs library to resize and create a grid of images / some other operations.

What's everyone working on this week (12/2023)?
There's also a CLI to convert between formats. It uses the crate image.

The `exr` crate got up to 3x faster, even better performance coming soon
exr is a is a 100% Rust and 100% safe code library for reading and writing OpenEXR images. It is used by the popular image crate to read and write OpenEXR.

Announcing zune-jpeg: Rust's fastest JPEG decoder
We're currently looking for contributors to add support for zune-jpeg to the image crate. The image maintainers are open to it, but don't have the capacity to do it themselves. You can find more details here.

Does the rust image crate support paletted png?
It would be helpful to contribute to the general change towards an untyped buffer with runtime representations for color space information and fallible conversions. (https://github.com/image-rs/image/pull/1718). It's currently stalling on having too few eyeballs to judge the impact and need for that complexity.

picst - a CLI tool to resize clipboard images on the fly
It uses https://github.com/1Password/arboard and https://github.com/image-rs/image under the hood. I haven't tested deeply but I assume it should handle many formats out of the box.
