扫描图像并将其保存在特定文件夹中

Question

我已经创建了一个Windows窗体应用程序来扫描任何图像。

扫描完成后，它会要求用户将其保存在任何文件夹中，但我希望图像保存在特定的文件夹中。

我使用的代码如下：

public class Scanner
{
    Device oDevice;
    Item oItem;
    CommonDialogClass dlg;

    public Scanner()
    {
        dlg = new CommonDialogClass();
        oDevice = dlg.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false);
    }

    public void Scann()
    {
        try
        {
            dlg.ShowAcquisitionWizard(oDevice);
        }
        catch (NullReferenceException ex)
        {
            MessageBox.Show(ex.Message);
        }

    }
}

private void button1_Click(object sender, EventArgs e)
{
   Scanner oScanner = new Scanner();
   oScanner.Scann();

   //Saving the image to the server directly
   button1.Text = "Image scanned";

   OpenFileDialog dlg = new OpenFileDialog();

   if (dlg.ShowDialog() == DialogResult.OK)
   {
       pictureBox1.Image = Image.FromFile(dlg.FileName);
   }            
}

Answer 1

使用CommonDialog.ShowTransfer method。

示例：

Device scanner = dialog.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false);
Item scannnerItem = scanner.Items[1];
// TODO: Adjust scanner settings.

ImageFile scannedImage = (ImageFile)dialog.ShowTransfer(scannnerItem, WIA.FormatID.wiaFormatPNG, false);
scannedImage.SaveFile("path");

你可以在wpf C#中使用扫描代码。Complete Scanning code in WPF C# using WIA, please visit this URL: http://10rem.net/blog/2010/01/08/scanning-images-in-wpf-via-wia
