套件：exiftags（1.01-7） [debports]
utility to read Exif tags from a digital camera JPEG file
The exiftags utility parses a specified JPEG file or, by default, its standard input, looking for a JPEG APP1 section containing Exif (Exchangeable Image File) data. The properties contained in these data are then printed to the standard output. Digital cameras typically add Exif data to the image files they produce, containing information about the camera and digitized image.
