Converting MatOfByte to Base64 string

Question

I'm using the following code to convert the matofbyte to base64

 Mat img = Imgcodecs.imread(paths.GetValue(0).ToString());
 MatOfByte vect = new MatOfByte();
 Imgcodecs.imencode(".JPG", img,vect);
        
 string encodedByte = System.Convert.ToBase64String((System.Text.Encoding.ASCII.GetBytes( vect.toArray().ToString())));

However the encoded string is too small through the image size of 1920x1080. Am I doing it right?

Answer 1

Try do not call ToString on byte[] .

You convert vect to byte[] and then to string, so GetBytes converts string something like "System.Byte[]".

string encodedByte = System.Convert.ToBase64String((System.Text.Encoding.ASCII.GetBytes( vect.toArray())));
