Korábban már többször említettem az ImageMagick programcsomagot, pontosabban annak convert programját. Most ImageMagick egy másik parancssoros programjára hívnám fel a figyelmet.
Az identify parancs segítségével egy képfájlról kaphatunk információt. Ez nem egyszerűen az EXIF információkat jelenti, hanem annál sokkal bővebb információhalmazt:
