## API

Pass `options` to the imagemin plugin and pass it to Metalsmith with the `use` method:

```js
const Metalsmith = require('metalsmith')
const imagemin = require('metalsmith-imagemin')

const metalsmith = new Metalsmith(__dirname)
  .use(imagemin({
    optimizationLevel: 3,
    svgoPlugins: [{ removeViewBox: false }]
  }))
```

### To configure plugin

Default `jpegrecompress` options will be overwritten:

```js
const Metalsmith = require('metalsmith')
const imagemin = require('metalsmith-imagemin')

const metalsmith = new Metalsmith(__dirname)
  .use(imagemin({
    optimizationLevel: 3,
    svgoPlugins: [{ removeViewBox: false }],

    jpegrecompress: { quality: 'veryhigh' }
  }))
```

### To disable/replace a default plugin

By default there are 4 plugins enabled:

```plain
gifsicle
jpegrecompress
pngquant
svgo
```

To disable a default plugin use `pluginname: null`, to disable **ALL** the default plugins use: `disableDefaults: true`

E.g. disable default `jpegrecompress` and replace it with another plugin (`mozjpeg`):

```js
const Metalsmith = require('metalsmith')
const imagemin = require('metalsmith-imagemin')

const metalsmith = new Metalsmith(__dirname)
  .use(imagemin({
    optimizationLevel: 3,
    svgoPlugins: [{ removeViewBox: false }],

    jpegrecompress: null,
    mozjpeg: {}
  }))
```

## CLI

You can also use the plugin with the Metalsmith CLI by adding `metalsmith-imagemin` key to your `metalsmith.json` plugins with any [imagemin](https://github.com/imagemin/imagemin) options you want, like so:

```json
{
  "plugins": {
    "metalsmith-imagemin": {
      "optimizationLevel": 3,
      "svgoPlugins": [{
        "removeViewBox": false
      }]
    }
  }
}
```
