if ( $settings['auto_orient'] ) {

I have a custom wp-cli command that update posts information (include featured image) from API. In terminal launch a lot of Notices:
Undefined index: auto_orient in /wp-content/plugins/kraken-image-optimizer/kraken.php on line 1150

Also:
Undefined index: preserve_meta_copyright in /wp-content/plugins/kraken-image-optimizer/kraken.php on line 1130

I think it would be a good idea to check that the $settings array contains all the keys
