The following functions are available:
- Normalize
- The function accumulates all unique artwork items by type within an album and causes every track to have a copy of each accumulated item. Tracks without Album fields are ignored.
- Largest First
- The function makes the largest artwork item the default (first), for every track. The item is assigned a picture type of Cover (front).
- Delete all But Largest
- The artwork is normalized then all but the largest artwork item is deleted.
- Remove Duplicates
- Duplicate artwork items are removed on a per track basis. An artwork item is a duplicate if its binary data exactly matches the binary data of another artwork item.
- Progressive JPEG to Baseline
- The items on this menu are used to re-encode progressive JPEG artwork items as baseline JPEGs. The Default menu item will only modify an artwork item if it is the default item (the first). All will modify all progressive JPEGs regardless as to their position.
