Property Value

The instance of the BarcodeReader class associated with this barcode engine that can be used to read barcodes from an image.

Remarks

The BarcodeReader class is used to read one or more barcodes from an image. You cannot create an instance of BarcodeReader directly, instead, use the instance created inside BarcodeEngine which is accessed through BarcodeEngine.Reader.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeReader_Example() 
{ 
   string[] imageFileNames = 
   { 
   Path.Combine(LEAD_VARS.ImagesDir, "Barcode1.tif"), 
   Path.Combine(LEAD_VARS.ImagesDir, "Barcode2.tif") 
 }; 
 
   // Create a Barcode engine 
   BarcodeEngine engine = new BarcodeEngine(); 
 
   // Get the Barcode reader instance 
   BarcodeReader reader = engine.Reader; 
 
   // Load the image 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      foreach (string imageFileName in imageFileNames) 
      { 
         using (RasterImage image = codecs.Load(imageFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1)) 
         { 
            // Read all the barcodes in this image 
            BarcodeData[] barcodes = reader.ReadBarcodes(image, LeadRect.Empty, 0, null); 
 
            // Print out the barcodes we found 
            Console.WriteLine("{0} contains {1} barcodes", imageFileName, barcodes.Length); 
            for (int i = 0; i < barcodes.Length; i++) 
            { 
               BarcodeData barcode = barcodes[i]; 
               Console.WriteLine("  {0} - {1} - {2}", i + 1, barcode.Symbology, barcode.Value); 
            } 
            Console.WriteLine("-----------------"); 
         } 
      } 
   } 
}
