Hello,

The barcode reader can test the quality of barcode print using the ISO 15415 barcode print quality test.

The ISO 15415 barcode print quality test uses different quiet zones for different barcode types as specified in specifications of barcode types.

Here is C# code that demonstrates how to change the allowable quiet zone for DataMatrix barcodes when recognized barcodes are tested using the ISO 15415 barcode print quality test:

barcodeReader.ISO15415QualityTestSettings = new Vintasoft.Barcode.QualityTests.ISO15415QualityTestSettings();
barcodeReader.ISO15415QualityTestSettings.SetQuietZoneSize(BarcodeType.DataMatrix, 1);

Best regards, Alexander

Hi, Alexander thanks for your reply.

While using reader.ISO15415QualityTestSettings.SetQuietZoneSize(BarcodeType.DataMatrix, 1)) function, we get error at this line. Error : System.NullReferenceException: 'Object reference not set to an instance of an object.'

Following is my some line of code

BarcodeReader reader = new BarcodeReader();
reader.Settings.ScanBarcodeTypes = BarcodeType.DataMatrix;
reader.Settings.ImageScaleFactor = 1f;
reader.Settings.ScanInterval = Convert.ToInt32(txtAdvanceParam.Text);
reader.Settings.ExpectedBarcodes = 1;
reader.Settings.SearchDistortedDataMatrixBarcodes = true;  
reader.Settings.SearchDistortedQRBarcodes = true;

reader.ISO15415QualityTestSettings.SetQuietZoneSize(BarcodeType.DataMatrix, 1); ////  error at this line
reader.Settings.RecognitionTimeout = 500;
reader.Settings.AutomaticRecognition = true;

Hello,

I updated my code in previous post. For solving the problem you need to initialize the barcodeReader.ISO15415QualityTestSettings property by instance of ISO15415QualityTestSettings class.

Hi,
I used your suggested code in our application, but SetQuietZoneSize not working in my code. Might be I make some mistakes. Please share complete sample code in C# with SetQuietZoneSize function. For reading datamatrix using image, and read quiet zone grade and value.

I apology for any inconvenience caused by sending same query.
Thanks,
Rohit

Hi Alex,
Thanks for your suggestion, I make some changes in my code. Now its working as per our requirement.
BarcodeReader reader = new BarcodeReader();
reader.Settings.ScanBarcodeTypes = BarcodeType.DataMatrix;
reader.Settings.ImageScaleFactor = 1f;
reader.Settings.ScanInterval = Convert.ToInt32(txtAdvanceParam.Text);
reader.Settings.ExpectedBarcodes = 1;

// modified code // :-)
:)
reader.ISO15415QualityTestSettings = new Vintasoft.Barcode.QualityTests.ISO15415QualityTestSettings();
reader.ISO15415QualityTestSettings.SetQuietZoneSize(BarcodeType.DataMatrix, 2);
