本文實(shí)例講述了python用來獲得圖片 exif信息的庫用法。分享給大家供大家參考。具體分析如下：

exif-py是一個(gè)純python實(shí)現(xiàn)的獲取圖片元數(shù)據(jù)的python庫，官方下載地址：

下面的代碼演示的是調(diào)用方法。

復(fù)制代碼代碼如下:

	# 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
