Public API changes and backwards compatibility

PDF file format

Added ability to save text as a graphic path when exporting to PDF format. This allows barcode text to be rendered as vector shapes, which improves compatibility with systems that do not embed fonts.

using (BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.QR, "Aspose"))
{
    gen.Parameters.Image.Pdf.IsTextAsPath = true;
    gen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.Below;
    gen.Parameters.Barcode.CodeTextParameters.Color = Color.Green;
    gen.Save("barcode.pdf", BarCodeImageFormat.Pdf);
}

Integration with Aspose.Drawing.Common

References to Aspose.Drawing.Common have been upgraded to version 25.7.0.

Code39 recognition quality

Recognition quality for Code39 barcodes has been enhanced, especially on low-quality or degraded images.

using (BarCodeReader reader = new BarCodeReader("code39.png", DecodeType.Code39FullASCII))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

EAN13, UPCA, EAN8, ISBN, ISMN, ISSN recognition speed

Recognition speed for EAN13, UPCA, EAN8, ISBN, ISMN, and ISSN barcodes has been significantly increased on mobile platforms.

using (BarCodeReader reader = new BarCodeReader("ean13.png", DecodeType.EAN13, DecodeType.UPCA, DecodeType.EAN8, DecodeType.ISBN, DecodeType.ISMN, DecodeType.ISSN))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

Two-out-of-five codes recognition speed

Recognition speed for Two-out-of-five codes has been significantly increased on mobile platforms. This includes barcode types such as DataLogic2of5, Interleaved2of5, ItalianPost25, ITF6, ITF14, OPC, DeutschePostIdentcode, DeutschePostLeitcode, Matrix2of5, MSI and Standard2of5.

using (BarCodeReader reader = new BarCodeReader("interleaved2of5.png", DecodeType.Interleaved2of5))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

Default recognition types for BarCodeReader

The default recognition types for BarCodeReader have been updated from DecodeType.AllSupportedTypes to DecodeType.MostCommonTypes. This change improves performance for typical recognition scenarios by reducing the number of barcode types scanned by default.

// Recognize using default (MostCommonTypes)
using (BarCodeReader reader = new BarCodeReader("barcode.png"))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

// Explicitly use MostCommonTypes
using (BarCodeReader reader = new BarCodeReader("barcode.png", DecodeType.MostCommonTypes))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

// Fallback to AllSupportedTypes (slower scan)
using (BarCodeReader reader = new BarCodeReader("barcode.png", DecodeType.AllSupportedTypes))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}

1D barcodes recognition speed

Recognition speed for most 1D barcode types has been increased when working with high-quality images. This enhancement is especially beneficial for barcode recognition from web pages or generated images, where input quality is typically high and distortion minimal.

// Generate a high-quality 1D barcode
BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.Code128, "Aspose");
gen.Parameters.Barcode.XDimension.Pixels = 2;
gen.Parameters.Barcode.BarHeight.Pixels = 150;
gen.Save(@"barcode.png", BarCodeImageFormat.Png);

// Recognize multiple 1D barcode types
using (BarCodeReader reader = new BarCodeReader("barcode.png", DecodeType.Code11, DecodeType.IATA2of5, DecodeType.EAN13, DecodeType.EAN8, DecodeType.Interleaved2of5, DecodeType.Standard2of5, DecodeType.UPCA, DecodeType.DataLogic2of5, DecodeType.DatabarOmniDirectional, DecodeType.DatabarExpanded, DecodeType.Code128, DecodeType.Code93, DecodeType.Matrix2of5, DecodeType.UPCE, DecodeType.DatabarLimited, DecodeType.Code39, DecodeType.MSI))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine(result.CodeText);
}
