MicroPDF417 found but not present in image

Aspose.BarCode Product Family

Aspose.Barcode is finding a MicroPDF417 barcode where non is present. Is there something it is detecting that is not obvious to me? smaller.png (322.4 KB)

The “rectange” in red represents the coordinates in which Aspose indicates that it found the barcode, but no barcode exists in that space.

I observe that the “CodeText” for this phantom result is “<UNKNOWNECI:000900>System.Byte[]</UNKNOWNECI>”, if that offers any insight.

@sferda,

I tested your scenario/case with the following sample code using Aspose.BarCode for .NET v23.5 with your image file, it works as expected.
e.g.
Sample code:

var bmp1 = new Bitmap("g:\\test2\\smaller.png");
using (Aspose.BarCode.BarCodeRecognition.BarCodeReader reader1 = new Aspose.BarCode.BarCodeRecognition.BarCodeReader(bmp1, Aspose.BarCode.BarCodeRecognition.DecodeType.AllSupportedTypes))
{
                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
CodeText: 08700216241793
Symbology Type: ITF14
CodeText: 08700216241793
Symbology Type: DataMatrix
CodeText: 20222315

The image attached is misleading; I was not able to upload the actual image we are processing due to limits on image size in this forum. Here is the actual file: MicroPDF417.zip (261.1 KB)
