Scanning the attached image at both High and Normal quality returns a barcode+garbagevalue not present in the image.

{CodeType = Code128, CodeText = “!>@”, Confidence = Moderate, ReadingQuality = 84.69631958007812}

I’m not sure what it’s seeing in this image. Thoughts?

@sferda,

Thanks for the barcode image.

Although your barcode image quality is poor. Anyways, I have tested your scenario/case and I was able to reproduce the issue in HighQuality setting/mode by using the following sample code with your barcode image.

var bmp1 = "e:\\test2\\barcode_and_background_rasterized_alt.png.trimmed.png";
using (Aspose.BarCode.BarCodeRecognition.BarCodeReader reader1 = new Aspose.BarCode.BarCodeRecognition.BarCodeReader(bmp1, Aspose.BarCode.BarCodeRecognition.DecodeType.AllSupportedTypes))
{
    reader1.QualitySettings = Aspose.BarCode.BarCodeRecognition.QualitySettings.HighQuality;

    Console.WriteLine(reader1.ReadBarCodes().Length);

    foreach (Aspose.BarCode.BarCodeRecognition.BarCodeResult result1 in reader1.ReadBarCodes())
    {
        // Read symbology type and code text
        Console.WriteLine("Symbology Type: " + result1.CodeType);
        Console.WriteLine("CodeText: " + result1.CodeText);
    }
}

output:

Symbology Type: ITF14

Symbology Type: Interleaved2of5
