VB.NET


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

    device.Open()
    device.PixelType = Vintasoft.Twain.PixelType.RGB
    device.UnitOfMeasure = Vintasoft.Twain.UnitOfMeasure.Inches
    device.Resolution = New Vintasoft.Twain.Resolution(200.0F, 200.0F)
    device.ImageLayout.[Set](1.0F, 1.0F, 5.0F, 5.0F)

    device.Acquire()
End Sub


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

    device.Open();
    device.PixelType = Vintasoft.Twain.PixelType.RGB;
    device.UnitOfMeasure = Vintasoft.Twain.UnitOfMeasure.Inches;
    device.Resolution = new Vintasoft.Twain.Resolution(200f, 200f);
    device.ImageLayout.Set(1f, 1f, 5f, 5f);
