<h1>@jimp/plugin-shadow</h1>
<p>Creates a shadow on an image.</p>
</div>
## Usage
- @param {function(Error, Jimp)} options (optional)
- opacity - opacity of the shadow between 0 and 1
- size,- of the shadow
- blur - how blurry the shadow is
- x - x position of shadow
- y - y position of shadow
- @param {function(Error, Jimp)} cb (optional) a callback for when complete
```js
import jimp from 'jimp';
async function main() {
const image = await jimp.read('test/image.png');
image.shadow();
// or
image.shadow({ opacity: 0.8, size: 1.2, blur: 10, x: -75, y: -75 });
}
main();
```
