Features and Improvements

Inverted Barcodes Recognition Performance

The recognition performance for inverted barcodes, where foreground and background colors are swapped, has been significantly improved. These enhancements provide more reliable decoding:

in scanned documents that contain negative or inverted images,
in high-contrast PDF files and document-processing workflows.

The feature can be enabled via the setInverseImage(InverseImageMode) quality setting:

public void example() {
    BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.DATA_MATRIX, "0126789ABCDEFabcdef");
    gen.getParameters().getBarcode().setBarColor(Color.WHITE);
    gen.getParameters().setBackColor(Color.BLACK);

    BarCodeReader reader = new BarCodeReader(gen.generateBarCodeImage(), DecodeType.DATA_MATRIX);
    reader.getQualitySettings().setInverseImage(InverseImageMode.ENABLED);
    for (BarCodeResult result : reader.readBarCodes()) {
        System.out.println(result.getCodeText());
    }
}
