 | Aspose.BarCode for Java provides better and faster barcode recognition using the following image processing algorithms:
These settings can be useful while detecting barcodes from scanned or slightly damaged images. The probability of barcode detection will increase by this setting. |
Programming Sample
The following code snippet shows how to use median smoothing, HLS and grayscale image processing techniques while recognizing the barcode:
[Java]
// read code39 barcode from image
String image = "code39Extended.jpg";
BarCodeReader reader = new BarCodeReader(Toolkit.getDefaultToolkit().getImage(image), BarCodeReadType.getCode39Standard());
// set grayscale image processing
reader.setHints(RecognitionHints.ImageBinarizationHints.getGrayscale());
// try to recognize all possible barcodes in the image
while (reader.read())
{
System.err.println("Codetext: " + reader.getCodeText());
}
// close reader
reader.close();
