Tizen enables you to access and modify EXIF information in a JPEG file. The Exif API is mandatory for both Tizen mobile and wearable profiles, which means that it is supported in all mobile and wearable devices. All mandatory APIs are supported on the Tizen Emulators.

Use:

    var fileURI = "";
    var myNewExif = new tizen.ExifInformation();


    function getSuccess(exifInfo)
    {
        console.log(exifInfo.orientation);
        console.log(exifInfo.userComment);
        console.log(exifInfo.gpsLocation);
    }

    function resolveSuccess(file)
    {
       fileURI = file.toURI();
       console.log("Successfully resolved file: " + file.toURI());

       function onSaveSuccess()
       {
          console.log("Successfully saved EXIF information to JPEG file");
       }

       function onSaveError(error)
       {
          console.log("Error occurred:" + error.name + " with message:" + error.message);
       }

       myNewExif.uri = file.toURI();
       myNewExif.orientation = "ROTATE_90";
       myNewExif.userComment = "Photo taken on Golden Bridge in Sanfrancisco";
       myNewExif.gpsLocation = new tizen.SimpleCoordinates(50.086447, 14.411856);
       tizen.exif.saveExifInfo(myNewExif, onSaveSuccess, onSaveError);
       tizen.exif.getExifInfo(fileURI, getSuccess);
    }

    function resolveFail(error)
    {
       console.log("resolve() error occurred: " + error.name + " with message: " + error.message);
    }

    tizen.filesystem.resolve("images/image1.jpg", resolveSuccess, resolveFail);
