# Library to extract EXIF information in digital camera image files
|
| 2 |
|
#
|
| 3 |
|
# To use this library call with:
|
| 4 |
|
# f=open(path_name, 'rb')
|
| 5 |
|
# tags=EXIF.process_file(f)
|
| 6 |
|
# tags will now be a dictionary mapping names of EXIF tags to their
|
| 7 |
|
# values in the file named by path_name. You can process the tags
|
| 8 |
|
# as you wish. In particular, you can iterate through all the tags with:
|
| 9 |
|
# for tag in tags.keys():
|
| 10 |
|
# if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename',
|
| 11 |
|
# 'EXIF MakerNote'):
|
| 12 |
|
# print "Key: %s, value %s" % (tag, tags[tag])
|
| 13 |
|
# (This code uses the if statement to avoid printing out a few of the
|
| 14 |
|
# tags that tend to be long or boring.)
|
| 15 |
|
#
|
| 16 |
|
# The tags dictionary will include keys for all of the usual EXIF
|
| 17 |
|
# tags, and will also include keys for Makernotes used by some
|
| 18 |
|
# cameras, for which we have a good specification.
|
| 19 |
|
#
|
| 20 |
|
# Contains code from "exifdump.py" originally written by Thierry Bousch
|
| 21 |
|
# <bousch@topo.math.u-psud.fr> and released into the public domain.

|
# 21-AUG-99 TB Last update by Thierry Bousch to his code.
|
| 67 |
|
# 17-JAN-02 CEC Discovered code on web.
|
| 68 |
|
# Commented everything.
|
| 69 |
|
# Made small code improvements.
|
| 70 |
|
# Reformatted for readability.
|
| 71 |
|
# 19-JAN-02 CEC Added ability to read TIFFs and JFIF-format JPEGs.
|
| 72 |
|
# Added ability to extract JPEG formatted thumbnail.
|
| 73 |
|
# Added ability to read GPS IFD (not tested).
|
| 74 |
|
# Converted IFD data structure to dictionaries indexed by
|
| 75 |
|
# tag name.
|
| 76 |
|
# Factored into library returning dictionary of IFDs plus
|
| 77 |
|
# thumbnail, if any.
|
| 78 |
|
# 20-JAN-02 CEC Added MakerNote processing logic.
|
| 79 |
|
# Added Olympus MakerNote.
|
| 80 |
|
# Converted data structure to single-level dictionary, avoiding
|
| 81 |
|
# tag name collisions by prefixing with IFD name. This makes
|
| 82 |
|
# it much easier to use.
|
| 83 |
|
# 23-JAN-02 CEC Trimmed nulls from end of string values.
|
| 84 |
|
