python用来获得图片exif信息的库实例分析
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。
#librarytest/debugfunction(dumpgivenfiles) if__name__=='__main__': importsys importgetopt #parsecommandlineoptions/arguments try: opts,args=getopt.getopt(sys.argv[1:],"hqsdt:v",["help","quick","strict","debug","stop-tag="]) exceptgetopt.GetoptError: usage(2) ifargs==[]: usage(2) detailed=True stop_tag='UNDEF' debug=False strict=False foro,ainopts: ifoin("-h","--help"): usage(0) ifoin("-q","--quick"): detailed=False ifoin("-t","--stop-tag"): stop_tag=a ifoin("-s","--strict"): strict=True ifoin("-d","--debug"): debug=True #outputinfoforeachfile forfilenameinargs: try: file=open(filename,'rb') except: print"'%s'isunreadable\n"%filename continue printfilename+':' #getthetags data=process_file(file,stop_tag=stop_tag,details=detailed,strict=strict,debug=debug) ifnotdata: print'NoEXIFinformationfound' continue x=data.keys() x.sort() foriinx: ifiin('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'indata: print'FilehasJPEGthumbnail' print
