    Read barcodes from Vintasoft.Imaging.VintasoftBitmap object
    In This Topic
    Example: Here is an example that shows how to recognize barcodes in Vintasoft.Imaging.VintasoftBitmap object.
    /// <summary>
    /// Reads barcode from a <see cref="Vintasoft.Imaging.VintasoftBitmap"/>.
    /// </summary>
