如何将exif数据添加到android上的照片

问题描述

我正在使用 react-native-camera 拍照。在选项中，我添加了坐标（这有效）和“ImageDescription”。但是记录响应时不会出现“ImageDescription”。然后我使用 react-native-exif 来读取文件的 exif 数据。 （我认为问题是由于api级别设置不正确，因为我得到的属性低于api级别9）我的代码：

  const takePhoto = async () => {
    let exifData = {};

    if(geoCoordinates.lat && geoCoordinates.lng){
      exifData = { 
        GPSLatitude: geoCoordinates.lat,GPSLongitude: geoCoordinates.lng,GPSAltitude: geoCoordinates.altitude,ImageDescription: "Here is description"
      };
    }

    const options = { quality: imageQuality,writeExif: exifData};
    const data = await takePicture(options);
    
    Exif.getExif(data.uri)
    .then(msg => console.log('OK: ' + JSON.stringify(msg)))
    .catch(msg => console.log('ERROR: ' + msg));
  };

日志：

OK: {"ImageWidth":1280,"ImageHeight":720,"Orientation":6,"originalUri":"/data/user/0/com.appmobile/cache/Camera/a2920351-9fa0-4254-baf0-44cab3ba7231.jpg","exif":{"originalUri":"/data/user/0/com.appmobile/cache/Camera/a2920351-9fa0-4254-baf0-44cab3ba7231.jpg","WhiteBalance":"0","SubSecTimeDigitized":"0","Orientation":"6","Make":"Google","ISOSpeedratings":"100","ImageWidth":"1280","SubSecTime":"0","GPSLongitude":"*longitud*","ImageLength":"720","GPSTimeStamp":null,"ExposureTime":"0.01","FocalLength":"5000/1000","GPSLatitudeRef":"N","GPSDateStamp":null,"GPSAltitudeRef":"0","GPSLatitude":"*latitude*","SubSecTimeOriginal":"0","GPSLongitudeRef":"W","DateTime":"2021:06:08 16:14:54","GPSAltitude":"0/10000","Flash":"0","GPSProcessingMethod":null,"Model":"sdk_gphone_x86","DateTimeDigitized":"2021:06:08 16:14:54","FNumber":"2.8"}}
