VB.NET


Public Sub ScanBlackWhiteImage(device As Vintasoft.Twain.Device)
        device.ShowUI = False
        device.DisableAfterAcquire = True

        device.Open()
        device.PixelType = Vintasoft.Twain.PixelType.BW
        device.PixelFlavor = Vintasoft.Twain.PixelFlavor.Chocolate
        device.UnitOfMeasure = Vintasoft.Twain.UnitOfMeasure.Inches
        device.Resolution = New Vintasoft.Twain.Resolution(200F, 200F)

        device.Acquire()
End Sub


public void ScanBlackWhiteImage(Vintasoft.Twain.Device device)
{
    device.ShowUI = false;
    device.DisableAfterAcquire = true;

    device.Open();
    device.PixelType = Vintasoft.Twain.PixelType.BW;
    device.PixelFlavor = Vintasoft.Twain.PixelFlavor.Chocolate;
    device.UnitOfMeasure = Vintasoft.Twain.UnitOfMeasure.Inches;
    device.Resolution = new Vintasoft.Twain.Resolution(200f, 200f);

    device.Acquire();
