# Library to extract EXIF information from digital camera image files
|
|
5 |
# http://sourceforge.net/projects/exif-py/
|
|
6 |
#
|
|
7 |
# VERSION 1.1.0
|
|
8 |
#
|
|
9 |
# To use this library call with:
|
|
10 |
# f = open(path_name, 'rb')
|
|
11 |
# tags = EXIF.process_file(f)
|
|
12 |
#
|
|
13 |
# To ignore MakerNote tags, pass the -q or --quick
|
|
14 |
# command line arguments, or as
|
|
15 |
# tags = EXIF.process_file(f, details=False)
|
|
16 |
#
|
|
17 |
# To stop processing after a certain tag is retrieved,
|
|
18 |
# pass the -t TAG or --stop-tag TAG argument, or as
|
|
19 |
# tags = EXIF.process_file(f, stop_tag='TAG')
|
|
20 |
#
|
|
21 |
# where TAG is a valid tag name, ex 'DateTimeOriginal'
|
|
22 |
#
|
|
23 |
# These 2 are useful when you are retrieving a large list of images
|
|
24 |
#
|
|
25 |
#
|
|
26 |
# To return an error on invalid tags,
|
|
27 |
# pass the -s or --strict argument, or as
|
|
28 |
# tags = EXIF.process_file(f, strict=True)
|
|
29 |
#
|
|
30 |
# Otherwise these tags will be ignored
|
|
31 |
#
|
|
32 |
# Returned tags will be a dictionary mapping names of EXIF tags to their
|
|
33 |
# values in the file named by path_name. You can process the tags
|
|
34 |
# as you wish. In particular, you can iterate through all the tags with:
|
|
35 |
# for tag in tags.keys():
|
|
36 |
# if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename',
|
|
37 |
# 'EXIF MakerNote'):
|
|
38 |
# print "Key: %s, value %s" % (tag, tags[tag])
|
|
39 |
# (This code uses the if statement to avoid printing out a few of the
|
|
40 |
# tags that tend to be long or boring.)
|
|
41 |
#
|
|
42 |
# The tags dictionary will include keys for all of the usual EXIF
|
|
43 |
# tags, and will also include keys for Makernotes used by some
|
|
44 |
# cameras, for which we have a good specification.
|
|
45 |
#
|
|
46 |
# Note that the dictionary keys are the IFD name followed by the
|
|
47 |
# tag name. For example:
|
|
48 |
# 'EXIF DateTimeOriginal', 'Image Orientation', 'MakerNote FocusMode'
