Barcode Reader Calibration
In This Topic
We have spent a lot of time and as result the automatic barcode recognition mode allows now to recognize barcodes from the most images.
Here are the recommended settings for barcode reader:
-
Use the automatic barcode recognition mode, i.e. set the value of ReaderSettings.AutomaticRecognition property to True.
-
If you know the count of barcodes on image, set the expected count of barcodes using ReaderSettings.ExpectedBarcodes property.
-
If the image contains "normal" barcodes ("normal" barcode has single bar/cell width from 2 to 20 pixels), set the value of ReaderSettings.BarcodeCharacteristics property to BarcodeCharacteristics.NormalSizeBarcodes.
-
If the image contains "small" barcodes ("small" barcode has single bar/cell width less than 2 pixels), set the value of ReaderSettings.BarcodeCharacteristics property to BarcodeCharacteristics.SmallBarcodes.
-
If the image contains "large" barcodes ("large" barcode has single bar/cell width greater than 20 pixels), calculate the image scale factor, which allows to convert source image with "large" barcodes into scaled image with "normal" barcodes, and set the image scale factor using ReaderSettings.ImageScaleFactor property.
If the automatic barcode recognition mode does not allow you to recognize barcodes from your image, you can disable the automatic barcode recognition mode and try to recognize barcodes in manual mode - please read about available settings for barcode reader in documentation for
ReaderSettings class.
If you are not satisfied with performance or quality of our barcode reader, please contact our support team at
support@vintasoft.com and we will try to provide you the best solution for recognition of your barcodes.
Note: We do not recommend to process images with barcodes (deskew, despeckle, etc) before barcode recognition.
This can change the barcode proportions and as result greatly decrease quality of barcode recognition.
