bgneal@1 4 # Library to extract EXIF information from digital camera image files
bgneal@1 5 # http://sourceforge.net/projects/exif-py/
bgneal@1 6 #
bgneal@1 7 # VERSION 1.0.7
bgneal@1 8 #
bgneal@1 9 # To use this library call with:
bgneal@1 10 # f = open(path_name, 'rb')
bgneal@1 11 # tags = EXIF.process_file(f)
bgneal@1 12 #
bgneal@1 13 # To ignore makerNote tags, pass the -q or --quick
bgneal@1 14 # command line arguments, or as
bgneal@1 15 # f = open(path_name, 'rb')
bgneal@1 16 # tags = EXIF.process_file(f, details=False)
bgneal@1 17 #
bgneal@1 18 # To stop processing after a certain tag is retrieved,
bgneal@1 19 # pass the -t TAG or --stop-tag TAG argument, or as
bgneal@1 20 # f = open(path_name, 'rb')
bgneal@1 21 # tags = EXIF.process_file(f, stop_tag='TAG')
bgneal@1 22 #
bgneal@1 23 # where TAG is a valid tag name, ex 'DateTimeOriginal'
bgneal@1 24 #
bgneal@1 25 # These are useful when you are retrieving a large list of images
bgneal@1 26 #
bgneal@1 27 # Returned tags will be a dictionary mapping names of EXIF tags to their
bgneal@1 28 # values in the file named by path_name. You can process the tags
bgneal@1 29 # as you wish. In particular, you can iterate through all the tags with:
bgneal@1 30 # for tag in tags.keys():
bgneal@1 31 # if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename',
bgneal@1 32 # 'EXIF MakerNote'):
bgneal@1 33 # print "Key: %s, value %s" % (tag, tags[tag])
bgneal@1 34 # (This code uses the if statement to avoid printing out a few of the
bgneal@1 35 # tags that tend to be long or boring.)
bgneal@1 36 #
bgneal@1 37 # The tags dictionary will include keys for all of the usual EXIF
bgneal@1 38 # tags, and will also include keys for Makernotes used by some
bgneal@1 39 # cameras, for which we have a good specification.
bgneal@1 40 #
bgneal@1 41 # Note that the dictionary keys are the IFD name followed by the
bgneal@1 42 # tag name. For example:
bgneal@1 43 # 'EXIF DateTimeOriginal', 'Image Orientation', 'MakerNote FocusMode'
