ICNS is a file format used by Apple to store icons for macOS applications. This crate provides a simple API for reading and (and soon)writing ICNS files.
Here's a simple example of how to read an ICNS file:
You can find this example in
examples/encode.rsor run it with:sh cargo run --example encode
```rust use std::fs::File; use std::io::prelude::*; use image::open; use icns_rs::{IcnsEncoder, IconFormats};
fn main() -> std::io::Result<()> { // Open the image let image = match open("example.png") { Ok(image) => image, Err(e) => { println!("Error opening file: {}", e); return Ok(()); } };
// Create the encoder
let mut encoder = IcnsEncoder::new();
encoder.data(image);
encoder.formats(IconFormats::recommended());
// Encode the image
let data = match encoder.build() {
Ok(data) => data,
Err(e) => {
println!("Error encoding image: {}", e);
return Ok(());
}
};
// Write data to file
let mut file = File::create("example.icns")?;
file.write_all(&data)?;
Ok(())
} ```

When I started building this, I didn't know there already was a ICNS lib for rust, but, after looking at it, it was not up to my standards because of the lack of ARGB, RGB, and, Mask support. I wanted to create a modern package that was easy to use and had a simple API. I also wanted to make sure that it was well documented and had a good test suite. I hope you enjoy using this package as much as I enjoyed making it!.
