Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inFormatAvlNet.BarcodeFormat?EAN13Format of the barcode. Default value: EAN13.
inMinGradientLengthfloat<0.0f, INF>8.0fMinimal gradient length of edge pixels used for detecting barcodes. Default value: 8.0f.
inBaseBarWidthint<1, INF>3Estimated width of the thinnest bar. Default value: 3.
inScanCountint<1, INF>5Number of scan lines used in detecting barcode. Default value: 5.
inScanWidthint<1, INF>5Width of the single scan. Default value: 5.
inMinStrengthfloat<0.0f, INF>5.0fMinimal strength of an extracted edge. Default value: 5.0f.
inSmoothingStdDevfloat<0.0f, INF>0.25fStandard deviation of the gaussian smoothing applied to the profile extracted in each scan. Default value: 0.25f.
inPolarityAvlNet.PolarityDarkSpecifies whether code is darker or brighter than the background. Default value: Dark.
outBarcodePositionsSystem.Collections.Generic.IList<AvlNet.Rectangle2D>Positions of the found barcodes.
outBarcodePolaritiesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Polarity>>Polarities of the found barcodes. Can be null to skip this parameter calculation.
outBarcodeCandidatesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Rectangle2D>>Places with high gradient values that are further investigated. Can be null to skip this parameter calculation.
