Read and Write GPS coordinates with RedCorners.ExifLibrary

I recently published RedCorners.ExifLibrary, a NuGet that lets you read and write EXIF metadata in image files. This is basically a fork of the ExifLibrary project by oozcitak, with four minor changes:

  • It removes dependencies to System.Drawing, making the library work across all .net Standard 2.0 compatible runtimes, including Xamarin.iOS and Xamarin.Android.
  • It adds a conversion helper method for going back and forth between floating point or Degrees/Minutes/Seconds representations for coordinates.
  • It adds helper methods to quickly read and write GPS coordinates in the image files.
  • Everything is moved to the RedCorners.ExifLibrary namespace, in order to make it possible to use both the original library and my version of it simultaneously.

It has been tested on Xamarin.iOS, Xamarin.Android, .NET Core and .NET Framework on JPEG images.

You can get the NuGet from here: https://www.nuget.org/packages/RedCorners.ExifLibrary

Some quick examples:


using RedCorners.ExifLibrary;

// Read GPS Coordinates
var file = ImageFile.FromFile(Path);
var coords = file.GetGPSCoords();
if (coords.HasValue)
    (Latitude, Longitude) = coords.Value;

// Write GPS Coordinates
var file = ImageFile.FromFile(Path);
file.SetGPSCoords(Latitude, Longitude);
file.Save(Path);
