Exiv2 照片EXIF信息库(c++)

前一段时间要做基于flicker提供的带有exif信息的照片库给无地理信息的photos进行定位。
大部分exif的库都不是很好用，exiv2 (exiv2) 挺不错。但在windows下编译很烦。

1 //need Qt4/Qt5 support 2 #include <QtCore> 3 #include <iostream> 4 #include <exiv2/exiv2.hpp> 5 using namespace std; 6 using namespace Exiv2; 7 8 QStringList loadFrFile(const char* sfilename) 9 19 20 QTextStream _in(&_file); 21 22 while(!_in.atEnd()) 23 28 29 cout<<"slist size = "<<slist.size()<<endl; 30 return slist; 31 } 32 33 34 int main() 35 43 image>readMetadata(); 44 ExifData ed = image>exifData(); 45 46 if(ed.empty()) 47 51 52 //se tag location 53 cout<<ed["Exif.Image.GPSTag"]<<endl; 54 cout<<ed["Exif.GPSInfo.GPSLatitudeRef"]<<endl; 55 cout<<ed["Exif.GPSInfo.GPSLatitude"]<<endl; 56 cout<<ed["Exif.GPSInfo.GPSLongitudeRef"]<<endl; 57 cout<<ed["Exif.GPSInfo.GPSLongitude"]<<endl; 58 cout<<ed["Exif.GPSInfo.GPSAltitudeRef"]<<endl; 59 cout<<ed["Exif.GPSInfo.GPSAltitude"]<<endl; 60 cout<<ed["Exif.GPSInfo.GPSDateStamp"]<<endl; 61 62 //test 64 QStringList slist = loadFrFile("/Users/Yaoyao/Documents/Code/ReadPhotoExif/ReadPhotoExif/exif_tags.txt"); 65 if(slist.size() == 0) 66 return 1; 67 68 foreach(QString str, slist) 69 74 catch (...) 75 79 } 80 81 82 image>clearExifData(); 83 84 return 1; 85 }
