RedCorners.ExifLibrary

RedCorners.ExifLibrary is a .NET Standard port of ExifLibrary by oozcitak. The original project can be found here, which is under MIT License.

This fork adds extensions to write and read GPS coordinates with one function call, and as floating point values.

Original documentation can be found here.

Easy Reading of GPS Coordinates

using RedCorners.ExifLibrary;
var file = ImageFile.FromFile(Path);
var coords = file.GetGPSCoords();
if (coords.HasValue)
    (Latitude, Longitude) = coords.Value;

Easy Writing of GPS Coordinates

using RedCorners.ExifLibrary;
var file = ImageFile.FromFile(Path);
file.SetGPSCoords(Latitude, Longitude);
file.Save(Path);

Low Level Modification of EXIF Properties

try
{
    var file = ImageFile.FromFile(Path);

    var objLat = GPSLatitudeLongitude.FromFloat(Latitude);
    var objLng = GPSLatitudeLongitude.FromFloat(Longitude);

    file.Properties.Set(ExifTag.GPSLatitude, objLat.d, objLat.m, objLat.s);
    file.Properties.Set(ExifTag.GPSLongitude, objLng.d, objLng.m, objLng.s);

    file.Save(Path);

    MessageBox.Show("File saved.");
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

Low Level Reading of EXIF Properties

try
{
    var file = ImageFile.FromFile(Path);

    var objLat = file.Properties[ExifTag.GPSLatitude] as GPSLatitudeLongitude;
    var objLng = file.Properties[ExifTag.GPSLongitude] as GPSLatitudeLongitude;

    Latitude = objLat?.ToFloat() ?? 0;
    Longitude = objLng?.ToFloat() ?? 0;
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}
RaisePropertyChanged(nameof(Latitude));
RaisePropertyChanged(nameof(Longitude));
