The object-oriented method allows more flexibility, but is slightly moreĬomplicated. My $info = $exifTool-> ImageInfo('image.jpg') Or in a more object-oriented fashion, by creating an ExifTool object: The ExifTool module may be used by simply calling the The following sections of this document give examples of how to use Image::ExifTool,Īnd explain the following individual functions in more detail: Write meta information in a wide variety of image, audio and video files.
