- @param {number} y the vertical position to blit the image
- @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');
const mask = await jimp.read('test/mask.png');
image.mask(mask);
}
```
