Convert BitmapImage to byte[] array in Windows Phone 8.1 Runtime

Question

There are a few samples to do this but they are for Windows Phone 8.0 or 8.1 Silverlight.

But how can you do this for Windows Phone 8.1 Runtime?

Answer 1

Tried this?

private byte[] ConvertToBytes(BitmapImage bitmapImage)
{
    byte[] data = null;
    using (MemoryStream stream = new MemoryStream())
    {
        WriteableBitmap wBitmap = new WriteableBitmap(bitmapImage);
        wBitmap.SaveJpeg(stream, wBitmap.PixelWidth, wBitmap.PixelHeight, 0, 100);
        stream.Seek(0, SeekOrigin.Begin);
        data = stream.GetBuffer();
    }

    return data;
}
