Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inBarcodePositionAvlNet.Rectangle2DPosition of the input image in which the barcode is located.
inBarcodePositionAlignmentAvlNet.CoordinateSystem2D?Adjusts the barcode rectangle to the position of the inspected object. Default value: atl::NIL.
inBarcodeFormatAvlNet.BarcodeFormat?EAN13Format of the barcode. Default value: EAN13.
inScanCountint<1, INF>5Number of parallel scans run until first successful read. 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.
outDecodedTextAvlNet.INullable<string>Decoded barcode text or nothing if all of the scans failed. This parameter cannot be null.
