Pixer provides image resizing, cropping, rotation, adjustments, encoding, and
batch processing through one Dart API. Rust does the image work through native
FFI or WebAssembly.

:::note
Pixer supports Android, iOS, Linux, macOS, Windows, and the web.
:::

## Install

Add Pixer to your `pubspec.yaml`:

```yaml
dependencies:
  pixer: ^0.0.10
```

Native binaries are downloaded automatically by Dart build hooks.

## Process an image

```dart
import 'package:pixer/pixer.dart';

final image = Pixer.fromFile('input.jpg');
try {
  final resized = image.resize(800, 600);
  try {
    resized.saveToFile('output.png');
  } finally {
    resized.dispose();
  }
} finally {
  image.dispose();
}
```

Every operation returns a new image. The source image is never changed.
