iris VS image

Take a look at the "iris" Github repository or install directly via crates.io

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.

You can use the image crate.

As for image processing, I'd start on crates.io and search for "image processing" and skim through to find the most downloaded crates -- image seems to be the most popular, with over 7 million downloads, so I'd check if that has what you want, and if not photon-rs seemed relatively mature with perhaps more features (albeit far less commonly used)

Glad it worked out for you—it seemed like the features are there for basic image conversion, but try to do something a little more sophisticated and you run into some severe design limits. Here is the kind of underlying problem I’m talking about:

https://github.com/image-rs/image/issues/1523

Side note the image-rs crate in the Rust ecosystem has no external dependencies and can encode and decode animated gifs and a variety of other image formats, 100% rust https://github.com/image-rs/image

I believe that photon uses image internally which only provides the ability to overlay another image. The crate imageproc extends image and adds the draw_text method.

And for image resizing I used the "image" crate: https://crates.io/crates/image. Note that while in development mode resizing an image takes a long time (several seconds for me), but in production mode it is lightning fast. I spent some time trying to figure this out :D

Why not just add support for QOI to image?

The image create is actually pretty good. It decodes a lot of stuff natively, and encodes to JPEG and PNG. I actually used it to make something very similar.

the image crate might be just what you're looking for. more specifically, the gif encoder can do exactly what you want.
