Apparently this project made it into the GitHub Archive Program.
Imager is a tool for automated image compression, and can competitively optimize very noisy, high resolution images into rather “tiny” files.

Thanks for imager! It's great!
BTW, I followed instructions in https://github.com/imager-io/imager/blob/master/docs/imager/install.md
It mentions imager v0.3.3, but it seems to be an auto release of v0.3.4.
Should the documentation be updated?
I came across your imager project on GitHub while looking at various image compression software. I was able to download and run it on Ubuntu, and it does a fantastic job on compression. Well done on developing this awesome utility!
I am now trying to compile it for a Raspberry Pi but am running into some errors.
I followed the steps in the 'install.md' file in the project:

Hey, great library!, is there an option to maintain alpha channel when converting PNG to webp, also, when I try to compress PNG, I only get a very small silluete of the image
Sometimes I get the following error message when batch compressing jpg files:
thread 'main' panicked at 'assertion failed: picture.uv_stride as u32 == width / 2', ~/.cargo/registry/src/github.com-1ecc6299db9ec823/imager-0.3.2/src/data.rs:276:9
Hi! First of all, I would like to really thank you for writing such a software, I've found it incredibly useful for image resizing, obtaining perceptible resolution losses only at 3x zoom at 1/8th of the original size!
That made me curious about what kind of compression algorithm the software uses, how generic it is (I have seen that you are trying to apply it to videos too, can't wait!), and what are your current thoughts on the development of the software.
Thanks again.

Optimized images should never be given to imager again. Trying to re-optimize the output again may lead to noticeable compression artifacts.
How does imager compare to compress-or-die in terms of compression ratio?
It'll be good to have AVIF format as possible output using a library like https://crates.io/crates/ravif
Sometimes I get the following error message when batch compressing files:
thread 'main' panicked at 'open input file path: ()', ~/.cargo/registry/src/github.com-1ecc6299db9ec823/imager-0.3.2/src/main.rs:150:73
I assume it's due to a wrong file type or something.
This appears to require the nightly rust compiler for successful compilation, along with a C++ compiler, llvm development extras, and clang tooling.
