Class BarCodeReader

  • java.lang.Object
    • com.aspose.barcode.barcoderecognition.BarCodeReader

  • public class BarCodeReader
extends java.lang.Object

    BarCodeReader encapsulates an image which may contain one or several barcodes, it then can perform ReadBarCodes operation to detect barcodes. 

     This sample shows how to detect Code39 and Code128 barcodes.
 
     BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_STANDARD, DecodeType.CODE_128);
 for(BarCodeResult result : reader.readBarCodes())
 {
    System.out.println("BarCode Type: " + result.getCodeTypeName());
    System.out.println("BarCode CodeText: " + result.getCodeText());
 }

 }
        Parameters:
        stream - The image stream for recogniton.

      • setBarCodeImage

        public void setBarCodeImage(Bitmap value)
