+
+Type: `boolean | undefined | null`<br>
+Default: `false`
+
+Enable [Adam7](https://en.wikipedia.org/wiki/Adam7_algorithm) PNG interlacing on any images that are processed. Interlaced images look better when they're loaded partially, but usually interlace makes compression less efficient. Set to `undefined` or `null` to keep the same interlacing as the input image.
+
+##### errorRecovery
+
+Type: `boolean`<br>
+Default: `true`
+
+A reasonable amount of effort will be spent to try to recover as much data as possible of a broken image, but the success cannot generally be guaranteed.

+Buffer to optimize.
