OCR

装完Microsoft Office Document Image后,在项目中分别引用、添加控件:Microsoft Office Document Imaging 11 Type Library,之后分别得到MODI名称空间下的Document、Image等主要操作文档类,以及用于显示文档的AxMODI.AxMiDocView控件;代码关键的有如下部分:


  private void SetImage(string filename)
  {
   // set the image..
   try
   {
    _MODIDocument = new MODI.Document();
    _MODIDocument.Create(filename);
    axMiDocView1.Document = _MODIDocument;
    axMiDocView1.Refresh();
   }
   catch(System.Runtime.InteropServices.COMException ee)
   {
    MessageBox.Show(ee.Message);
   }
  }
 

  public void Analyse()
  {
   if (_MODIDocument == null) return;
   try
   {
    // add event handler for progress visualisation
    //_MODIDocument.OnOCRProgress +=  new MODI._IDocumentEvents_OnOCRProgressEventHandler(this.ShowProgress);
               
    // the MODI call for OCR
//    _MODIDocument.OCR(_MODIParameters.Language,_MODIParameters.WithAutoRotation,_MODIParameters.WithStraightenImage);
    _MODIDocument.OCR(MODI.MiLANGUAGES.miLANG_CHINESE_SIMPLIFIED, true, true);

    this.textBox1.Text = (_MODIDocument.Images[0] as MODI.Image).Layout.Text;
    //statusBar1.Text = "Ready.";

    _MODIDocument.Close(false);
    _MODIDocument = null;
   }
   catch(Exception ee)
   {
    // simple exception "handling"
    MessageBox.Show(ee.Message);
   }
  }
