inRoi | AvlNet.Rectangle2D? | Range of pixels to be processed. Default value: atl::NIL. | |||
inRoiAlignment | AvlNet.CoordinateSystem2D? | Adjusts the barcode rectangle to the position of the inspected object. Default value: atl::NIL. | |||
inBarcodeFormat | AvlNet.BarcodeFormat? | EAN13 | Format of the barcode. Default value: EAN13. | ||
inMinGradientLength | float | <0.0f, INF> | 8.0f | Minimal gradient length of edge pixels used for detecting barcodes. Default value: 8.0f. | |
inBaseBarWidth | int | <1, INF> | 3 | Estimated width of the thinnest bar. Default value: 3. | |
inDetectionScanCount | int | <1, INF> | 5 | Number of scan lines used in detecting barcode. Default value: 5. | |
inReadingScanCount | int | <1, INF> | 5 | Number of parallel scans run until first successful read. Default value: 5. | |
inScanWidth | int | <1, INF> | 5 | Width of the single scan. Default value: 5. | |
inMinStrength | float | <0.0f, INF> | 5.0f | Minimal strength of an extracted edge. Default value: 5.0f. | |
inSmoothingStdDev | float | <0.0f, INF> | 0.25f | Standard deviation of the gaussian smoothing applied to the profile extracted in each scan. Default value: 0.25f. | |
