ImageGear .NET
Recognize a Multi-Page Document

In this example, the application specifies the output format (Converters.Text.Word2000) for the final output document (MULTIPAG.DOC) with the Format property. Then the multi-page result of the recognition stored in the recognition data file is converted into the requested format with the ImGearRecOutputManager.WriteDocument Method call.

C#
Copy Code
ImGearRecDocument document = ImGearRecDocument.Create(null);
using (FileStream content = new FileStream("MULTIPAG.TIF", FileMode.Open))
{
     int numPages = ImGearFileFormats.GetPageCount(content, ImGearFormats.UNKNOWN);
     for (int i = 0; i < numPages; i++)
     {
          ImGearPage igPage = ImGearFileFormats.LoadPage(content, i);
          ImGearRecPage igRecPage = igRecognition.ImportPage((ImGearRasterPage)igPage);
          igRecPage.Image.Preprocess();
          igRecPage.Recognize();
          document.InsertPage(igRecPage, -1);
     }
}
igRecognition.OutputManager.CodePage = "Windows ANSI";
igRecognition.OutputManager.Level = ImGearRecOutputLevel.AUTO;
igRecognition.OutputManager.Format = "Converters.Text.Word2000";
igRecognition.OutputManager.WriteDocument(document, "MULTIPAG.DOC");
document.Dispose();
VB .NET
Copy Code
Dim document As ImGearRecDocument = ImGearRecDocument.Create(Nothing)
Using content As New FileStream("MULTIPAG.TIF", FileMode.Open)
      Dim numPages As Integer = ImGearFileFormats.GetPageCount(content, ImGearFormats.UNKNOWN)
      Dim i As Integer = 0
      While i < numPages
           Dim igPage As ImGearPage = ImGearFileFormats.LoadPage(content, i)
           Dim igRecPage As ImGearRecPage = igRecognition.ImportPage(DirectCast(igPage, ImGearRasterPage))
           igRecPage.Image.Preprocess()
           igRecPage.Recognize()
           document.InsertPage(igRecPage, -1)
           System.Math.Max(System.Threading.Interlocked.Increment(i), i - 1)
      End While
End Using
igRecognition.OutputManager.CodePage = "Windows ANSI"
igRecognition.OutputManager.Level = ImGearRecOutputLevel.AUTO
igRecognition.OutputManager.Format = "Converters.Text.Word2000"
igRecognition.OutputManager.WriteDocument(document, "MULTIPAG.DOC")
document.Dispose()
