本文实例讲述了python用来获得图片exif信息的库用法。分享给大家供大家参考。具体分析如下：

exif-py是一个纯python实现的获取图片元数据的python库，官方下载地址：

http://exif-py.svn.sourceforge.net/viewvc/exif-py/source/EXIF.py?revision=19&view=markup

下面的代码演示的是调用方法。

复制代码 代码如下:# library test/debug function (dump given files)

if __name__ == '__main__':

import sys

import getopt

# parse command line options/arguments

try:

opts, args = getopt.getopt(sys.argv[1:], "hqsdt:v", ["help", "quick", "strict", "debug", "stop-tag="])

except getopt.GetoptError:

usage(2)

if args == []:

usage(2)

detailed = True

stop_tag = 'UNDEF'

debug = False

strict = False

for o, a in opts:

if o in ("-h", "--help"):

usage(0)

if o in ("-q", "--quick"):

detailed = False

if o in ("-t", "--stop-tag"):

stop_tag = a

if o in ("-s", "--strict"):

strict = True

if o in ("-d", "--debug"):

debug = True

# output info for each file

for filename in args:

try:

file=open(filename, 'rb')

except:

print "'%s' is unreadablen"%filename

continue

print filename + ':'

# get the tags

data = process_file(file, stop_tag=stop_tag, details=detailed, strict=strict, debug=debug)

if not data:

print 'No EXIF information found'

continue

x=data.keys()

x.sort()

for i in x:

if i in ('JPEGThumbnail', 'TIFFThumbnail'):

continue

try:

print ' %s (%s): %s' %

(i, FIELD_TYPES[data[i].field_type][2], data[i].printable)

except:

print 'error', i, '"', data[i], '"'

if 'JPEGThumbnail' in data:

print 'File has JPEG thumbnail'

print
