下面的代码演示的是调用方法。
# 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:
fileopen(filename, rb)
except:
print %s is unreadable\n%filename
continue
print filename :
# get the tags
data process_file(file, stop_tagstop_tag, detailsdetailed, strictstrict, debugdebug)
if not data:
print No EXIF information found
continue
xdata.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。
