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 unreadable\\n\”%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
希望本文所述对大家的Python程序设计有所帮助。
