В этом разделе

Пример: Вот пример, который показывает, как создать изображение штрих-кода в виде объекта Vintasoft.Imaging.VintasoftBitmap.

/// <summary>
/// Allows to generate barcode as bitmap.
/// </summary>
public static class BitmapBarcodeGenerator
{
    /// <summary>
    /// Initializes the <see cref="BitmapBarcodeGenerator"/> class.
    /// </summary>
    static BitmapBarcodeGenerator()
    {
        // initialize Vintasoft.Barcode.Gdi assembly - must be called only once
        // initialization is necessary if text value of barcode should be drawn on barcode image
        Vintasoft.Barcode.GdiAssembly.Init();
    }

    /// <summary>
    /// Returns the Code128 barcode as <see cref="Vintasoft.Imaging.VintasoftBitmap"/>.
    /// </summary>
    /// <param name="value">The barcode value.</param>
    /// <returns>A <see cref="Vintasoft.Imaging.VintasoftBitmap"/> object.</returns>
    public static Vintasoft.Imaging.VintasoftBitmap GetCode128BarcodeAsBitmap(string value)
    {
        // create the barcode writer
        using (Vintasoft.Barcode.BarcodeWriter barcodeWriter = new Vintasoft.Barcode.BarcodeWriter())
        {
            // set barcode writer settings
            barcodeWriter.Settings.Barcode = Vintasoft.Barcode.BarcodeType.Code128;
            barcodeWriter.Settings.Value = value;

            // get a barcode image as Vintasoft.Imaging.VintasoftBitmap
            return barcodeWriter.GetBarcodeAsVintasoftBitmap();
        }
    }
}
