Hi Patrik,

Sorry for the delay. We have prepared the sample based on your requirement. Using the GetSignatureAsync method, we can get signature image data as string.  Using that base64 string we can save the image in wwwroot folder shown as below.

    static string path = @"..."; // give your folder in the application for storing

private async void OnSave()

    {

        string sign = await signature.GetSignatureAsync();

        var image = sign.Replace("data:image/png;base64,", "");

        string fileNameWitPath = path + DateTime.Now.ToString().Replace("/", "-").Replace(" ", "- ").Replace(":", "") + ".png";

        using (FileStream fs = new FileStream(fileNameWitPath, FileMode.Create))

        {

            using (BinaryWriter bw = new BinaryWriter(fs))

            {

                byte[] data = Convert.FromBase64String(image);

                bw.Write(data);

                bw.Close();

            }

        }

    }

Check with attached sample and get back to us if you need any further assistance on this.
