# Windows Icons


A simple Rust library to extract icons from files and running processes on Windows platforms.

## Features


- Retrieve icons by file path or process id
- Request Explorer-aligned sizes (`Small` 16, `Medium` 48, `Large` 96, `ExtraLarge` 256)
- Save as a PNG or base64 encoded string

## Installation


Add to your `Cargo.toml`:

```toml
[dependencies]
windows-icons = "0.4.0"
```

## Usage


```rust
use windows_icons::{get_icon_by_path, get_icon_by_path_with_size, IconSize};

// Get icon as an image from a file path
let icon = get_icon_by_path("C:\\Windows\\System32\\notepad.exe").unwrap();
icon.save("notepad.png").unwrap();

// Get icon at an Explorer-aligned size
let icon = get_icon_by_path_with_size(
    "C:\\Windows\\System32\\notepad.exe",
    IconSize::Large,
).unwrap();
icon.save("notepad_large.png").unwrap();

// Get icon as a base64 string from a file path
let base64 = get_icon_base64_by_path("C:\\Windows\\System32\\calc.exe").unwrap();
println!("Calculator icon: {}", base64);

// Get icon as an image from dll
let folder = DllIcon::new().with_shell32(5);
let icon = get_icon_by_dll(folder).unwrap();
icon.save("output/folder.png").unwrap();

// Get icon as a base64 string frome dll
let explorer = DllIcon::new().with_explorer(1);
let base64 = get_icon_base64_by_dll(explorer).unwrap();
println!("Explorer: {}", base64);

// Get icon as an image from a process ID
let process_id = 1234;

let icon = get_icon_by_process_id(process_id).unwrap();
icon.save("process.png").unwrap();

// Get icon as a base64 encoded string from a process ID
let base64 = get_icon_base64_by_process_id(process_id).unwrap();
println!("Process {} icon: {}", process_id, base64);
```

For more examples, check the [`examples`](examples).

`cargo run --example icon`

`cargo run --example process -- <process id>`

`cargo run --example dll`

The `process` example is the easiest way to check a UWP app, since the install folder
under `WindowsApps` is not readable without elevation: start the app, then pass its
process id.
