How to create predefined session setup for high-volume TWAIN image scanner?

In This Topic

VintaSoft TWAIn .NET SDK allows to load/save predefined session setups for mid- and high-volume TWAIN image scanners.

Here is an example that demonstrates how to save the current TWAIN device settings to XML file:

/// <summary>
/// Saves the device settings.
/// </summary>
public void SaveDeviceSettings(Vintasoft.Twain.Device device)
{
    // open the device
    device.Open();

    using (System.IO.FileStream fs = new System.IO.FileStream("scanner-setup.xml", System.IO.FileMode.Append, System.IO.FileAccess.Write))
    {
        device.SaveSettings(fs);
    }
}

VB.NET

''' <summary>
''' Saves the device settings.
''' </summary>
Public Sub SaveDeviceSettings(device As Vintasoft.Twain.Device)
    ' open the device
    device.Open()

    Using fs As New System.IO.FileStream("scanner-setup.xml", System.IO.FileMode.Append, System.IO.FileAccess.Write)
        device.SaveSettings(fs)
    End Using
End Sub

Here is an example that demonstrates how to load previously saved TWAIN device settings into TWAIN device:

/// <summary>
/// Loads the device settings.
/// </summary>
public void LoadDeviceSettings(Vintasoft.Twain.Device device)
{
    // open the device
    device.Open();

    using (System.IO.FileStream fs = new System.IO.FileStream("scanner-setup.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read))
    {
        device.LoadSettings(fs);
    }
}

VB.NET

''' <summary>
''' Loads the device settings.
''' </summary>
Public Sub LoadDeviceSettings(device As Vintasoft.Twain.Device)
    ' open the device
    device.Open()

    Using fs As New System.IO.FileStream("scanner-setup.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read)
        device.LoadSettings(fs)
    End Using
End Sub
