Scan File From Scanner Using Flatbed And ADF With Windows Image Acquisition (WIA)

In this blog, I am going to give the solution for creating a windows application to connect your system toa scanner and scan the files from the scanner using WIA and save it to your local drive.

WIA (Flatbed and ADF)

Some important points you have to follow before starting the development:

1. Before starting you should know something about WIA.
2. Read about Windows image Acquisition properties and features.
3. You have to import the Interop.WIA.dll

Steps you need to follow for development:

1. Open your visual studio, go to file and create windows form application.
2. Select language as c#.
3. Give your application name as you want.
4. Now go to the solution explorer right click and add form.
5. Take one button control.

Now generate the click event of scan button.

Now you have to write the code for calling the scanner properties initializing the device and process , so you have to write this code into your form Initialization event.

Most Important point is You have to add reference of Interop.WIA.dll,

public Form2()
{
    InitializeComponent();
    //Get default device Id
    _deviceId = FindDefaultDeviceId();
    //Find Device
    _deviceInfo = FindDevice(_deviceId);
    //Connect the device
    _device = _deviceInfo.Connect();
}
private DeviceInfo FindDevice(string deviceId)
{
        DeviceManager manager = new DeviceManager();
        foreach(DeviceInfo info in manager.DeviceInfos)
        if (info.DeviceID == deviceId)
            return info;
        return null;
    }
    //finding the device Id here
private string FindDefaultDeviceId()
{
    string deviceId = Properties.Settings.Default.ScannerDeviceID;
    if (String.IsNullOrEmpty(deviceId))
    {
        // Select a scanner
        WIA.CommonDialog wiaDiag = new WIA.CommonDialog();
        Device d = wiaDiag.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false);
        if (d != null)
        {
            deviceId = d.DeviceID;
            Properties.Settings.Default.ScannerDeviceID = deviceId;
            Properties.Settings.Default.Save();
        }
    }
    return deviceId;
}

Copy and paste below code:

public List < Image > ScanPages(int dpi = 150, double width = 8.5, double height = 11)
{
    Item item = _device.Items[1];
    // configure item of the device
    SetDeviceItemProperty(ref item, 6146, 2); // greyscale
    SetDeviceItemProperty(ref item, 6147, dpi); // 150 dpi
    SetDeviceItemProperty(ref item, 6148, dpi); // 150 dpi
    SetDeviceItemProperty(ref item, 6151, (int)(dpi * width)); // set scan width
    SetDeviceItemProperty(ref item, 6152, (int)(dpi * height)); // set scan height
    SetDeviceItemProperty(ref item, 4104, 8); // bit depth
    // Detect if the ADF is loaded, if not use the flatbed
    List < Image > images = GetPagesFromScanner(ScanSource.DocumentFeeder, item);
    if (images.Count == 0)
    {
        // check the flatbed if ADF is not loaded, try from flatbed
        DialogResult dialogResult;
        do
        {
            List < Image > singlePage = GetPagesFromScanner(ScanSource.Flatbed, item);
            images.AddRange(singlePage);
            dialogResult = MessageBox.Show("Do you want to scan another page?", "ScanToEvernote", MessageBoxButtons.YesNo);
        }
        while (dialogResult == DialogResult.Yes);
    }
    return images;
}
private List < Image > GetPagesFromScanner(ScanSource source, Item item)
{
    SetDeviceProperty(ref _device, 3088, (int) source);
    List < Image > images = new List < Image > ();
    int handlingStatus = GetDeviceProperty(ref _device, WIA_DPS_DOCUMENT_HANDLING_STATUS);
    if ((source == ScanSource.DocumentFeeder && handlingStatus == FEED_READY) || (source == ScanSource.Flatbed && handlingStatus == FLATBED_READY)) {
        do {
            ImageFile wiaImage = null;
            try {
                wiaImage = item.Transfer(WIA_FORMAT_JPEG);
            } catch (COMException ex)
            {
                if ((uint) ex.ErrorCode == WIA_ERROR_PAPER_EMPTY)
                    break;
                else
                    throw;
            }
            if (wiaImage != null)
            {
                System.Diagnostics.Trace.WriteLine(String.Format("Image is {0} x {1} pixels", (float) wiaImage.Width / 150, (float) wiaImage.Height / 150));
                Image image = ConvertToImage(wiaImage);
                images.Add(image);
            }
        }
        while (source == ScanSource.DocumentFeeder);

Note: Add the final. You have to set the properties of device ID, check the below Image,

This is the final solution with WIA. If you have any doubts and/or problems you can contact me any time.

All the best!
