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:

• on mobile devices under variable lighting conditions,
• 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 InverseImage quality setting:

using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.DataMatrix, "0126789ABCDEFabcdef"))
{
    gen.Parameters.Barcode.BarColor = Color.White;
    gen.Parameters.BackColor = Color.Black;

    using (BarCodeReader reader = new BarCodeReader(gen.GenerateBarCodeImage(), DecodeType.DataMatrix))
    {
        reader.QualitySettings.InverseImage = InverseImageMode.Enabled;
        foreach (BarCodeResult result in reader.ReadBarCodes())
            Console.WriteLine(result.CodeText);
    }
}
