Decode Codabar Barcode from Image File in ASP.NET Website

      string[] results = BarcodeReader.read("c:/codabar-aspnet.gif", BarcodeReader.CODABAR);

     Dim datas() As String = BarcodeReader.read("c:/codabar-aspnet.gif ", BarcodeReader.CODABAR)

Enhance Codabar Barcode Reading Speed in ASP.NET Web Service

1. Scan large-size Codabar barcode using ASP.NET barcode reading dll
   
   If there is only one but a maximum Codabar barcode in the target file, you can set "maxOneBarcodePerPage" to true when you are scanning Codabar in ASP.NET web application.
   
   If you set the value of "maxOneBarcodePerPage" to true, the ASP.NET barcode reader library will stop scanning once it detects one Codabar barcode. But if you keep the default value of "maxOneBarcodePerPage", the ASP.NET barcode reader library will decode the Codabar from 4 directions with total five algorithms.
   
   
2. Detect Codabar barcode by scanning partial source image file in ASP.NET
   
   Using this ASP.NET barcode reader library, you can easily detect & read Codabar barcode from any part of the source image file. For example, if you want to read Codabar barcode in the top 20% and bottom 20% area, you can use following C# or VB.NET class codes.
   
   The most top left point of source image is (0%, 0%) and the most bottom right point is (100%, 100%).

     OptimizeSetting setting = new OptimizeSetting();
    
     setting.setMaxOneBarcodePerPage(true);
    
     ScanArea top20 = new ScanArea(new PointF(0.0F, 0.0F), new PointF(100.0F, 20.0F));

     ScanArea bottom20 = new ScanArea(new PointF(0.0F, 80.0F), new PointF(100.0F, 100.0F));
    
     List<ScanArea> areas = new List<ScanArea>();
     areas.Add(top20);
     areas.Add(bottom20);
    
     setting.setAreas(areas);
    
     string[] results = BarcodeReader.read("c:/codabar-aspnet.gif ", BarcodeReader.CODABAR, setting);

     Dim setting As OptimizeSetting = New OptimizeSetting()

     setting.setMaxOneBarcodePerPage(True)

     Dim top20 As ScanArea = New ScanArea(New Drawing.PointF(0.0F, 0.0F), New Drawing.PointF(100.0F, 20.0F))

     Dim bottom20 As ScanArea = New ScanArea(New Drawing.PointF(0.0F, 80.0F), New Drawing.PointF(100.0F, 100.0F))

     Dim areas As List(Of ScanArea) = New List(Of ScanArea)
     areas.Add(top20)
     areas.Add(bottom20)

     setting.setAreas(areas)

     Dim datas() As String = BarcodeReader.read("c:/codabar-aspnet.gif ", BarcodeReader.CODABAR, setting)
