Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.Rectangle2D? | Region of interest. Default value: atl::NIL. | |||
inRoiAlignment | AvlNet.CoordinateSystem2D? | Adjusts the region of interest 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. | |
inPolarity | AvlNet.Polarity | Dark | Specifies whether code is darker or brighter than the background. Default value: Dark. | ||
outBarcodePosition | AvlNet.Rectangle2D? | Position of the found barcode. | |||
outDecodedText | AvlNet.INullable<string> | Decoded barcode content or nothing if all of the scans failed. This parameter cannot be null. | |||
outBarcodeFormat | AvlNet.BarcodeFormat? | Decoded barcode format or nothing if all of the scans failed. | |||
outBarcodePolarity | AvlNet.Polarity? | Decoded barcode polarity or nothing if all of the scans failed. | |||
outAlignedRoi | AvlNet.Rectangle2D | Input ROI after transformation (in the image coordinates). | |||
outBarcodeCandidates | System.Collections.Generic.IList<AvlNet.Rectangle2D> | Places with high gradient values that are further investigated. | |||
diagGradientImage | AvlNet.Image | Image of gradient directions. | |||
diagScheduledScanSegments | System.Collections.Generic.IList<AvlNet.Segment2D> | Scheduled scan segments. |
