Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImage | Avl.Image | Input image. | ||
| inScanPath | Avl.Path | Path along which the scan is performed. | ||
| inScanPathAlignment | Atl.Optional<Avl.CoordinateSystem2D> | Adjusts the scan path to the position of the inspected object. Default value: atl::NIL. | ||
| inScanWidth | int | <1, INF> | 5 | Width of the scan field in pixels. Default value: 5. |
| inSamplingParams | Avl.SamplingParams | SamplingParams ( Interpolation: Bilinear SamplingStep: 1.0f SampleCount: Nil ) | Parameters controlling the sampling process. Default value: SamplingParams ( Interpolation: Bilinear SamplingStep: 1.0f SampleCount: Nil ). | |
| inEdgeScanParams | Avl.EdgeScanParams | EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: BrightToDark ) | Parameters controlling the edge extraction process. Default value: EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f EdgeTransition: BrightToDark ). | |
| inEdgeSelection | Avl.Selection | Selection mode of the resulting edge. | ||
| inLocalBlindness | Atl.Optional<Avl.LocalBlindness> | Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL. | ||
 | outEdge | Atl.Conditional<Avl.Edge1D> | Found edge. | ||
| outAlignedScanPath | Atl.Optional<Avl.Path> | Transformed input path. | ||
| outBrightnessProfile | Atl.Optional<Avl.Profile> | Extracted image profile. | ||
| outResponseProfile | Atl.Optional<Avl.Profile> | Profile of the edge (derivative) operator response. | ||
 | diagSamplingPoints | Avl.Diagnostic<System.Collections.Generic.List<Avl.Path>> | Array of paths each one containing the sampling points that contributes to a single value of the extracted profile. | ||
| diagSamplingStep | Avl.Diagnostic<float> | Used distance between consecutive sampling points on the scan path. |
