About 2D DataMatrix


i have downloaded your trial version of aspose.barcode for .net. but when i use barcode.toolkit.exe to test whether it can recognize all barcodes. but i find there is a 2D barcode, datamatrix image, which can not be recognized.

could you help to confirm, whether your software can recognize datamatrix well?

enclosing is the test image.

thanks for your help. hope for your quickly answer.

my email is : qi.fan@sinictek.com

But I test it use 7.1.0 and 7.2.0 aspose barcode recognition demo

both still meet problems.

no barcode uncognized?

which scan setting i must use?

i try to fuzzy it, but still unuseful.


Thank you for the inquiry. Please use the following sample code:

[.NET, C#]
// load barcode picture
BarCodeReader reader = new BarCodeReader(@“C:\AB\test426\DataMatrix_1.jpg”, BarCodeReadType.DataMatrix);
// set recognition mode
reader.RecognitionMode = RecognitionMode.ManualHints;
// apply filter
reader.ManualHints = ManualHint.InvertImage;
// scan barcode image
while (reader.Read())
Console.WriteLine("Type: " + reader.GetReadType() + " Code: " + reader.GetCodeText());

Type: DataMatrix Code: UMT471120001047

But i get the evaluation version using (Aspose_BarCode_NET-master).

it can only recognize code39 using C# Code.

i only can run the Aspose barcode toolkit.exe, it can not recognize most 2D Datamatrix.

i dont know whether you could give me one -month evaluation LICENSE?

I need to completely evaluate the software performance then buy it.

thanks for your help

Ok, thanks

i get the result for the image

i make it binary and invert , then toolkit can recognize it,

thanks a lot.
