| inPattern | System.Collections.Generic.IList<AvlNet.Point2D> | Point pattern to be found. | ||
| inAllowRotation | bool | True | Flag indicating whether rotation is allowed as a part of output alignment. Default value: True. | |
| inMinAngle | float | -180.0f | Start of range of possible rotations. Default value: -180.0f. | |
| inMaxAngle | float | 180.0f | End of range of possible rotations. Default value: 180.0f. | |
| inAllowScale | bool | False | Flag indicating whether scale is allowed as a part of output alignment. Default value: False. | |
| inMinScale | float | <0.0f, INF> | 0.8f | Start of range of possible scales. Default value: 0.8f. |
| inMaxScale | float | <0.0f, INF> | 1.25f | End of range of possible scales. Default value: 1.25f. |
| inTilingFactor | float | <0.000001f, 1.0f> | 0.2f | Defines relative size of the square tile on the plane during initial detection. Default value: 0.2f. |
| inMinInitialScore | float | <0.0f, 1.0f> | 0.75f | The minimum proportion of points correctly matched during initial detection. Default value: 0.75f. |
| inMaxDeviation | float | <0.0f, INF> | 5.0f | Maximal distance between two points considered matched. Default value: 5.0f. |
| inMinScore | float | <0.0f, 1.0f> | 0.75f | The minimum proportion of points correctly matched. Default value: 0.75f. |
 | outObject | AvlNet.Rectangle2D? | Bounding rectangle of the found pattern occurrence. | ||
| outAlignedPattern | AvlNet.INullable<System.Collections.Generic.List<AvlNet.Point2D>> | The aligned input pattern points. This parameter cannot be null. | ||
| outAlignment | AvlNet.CoordinateSystem2D? | The transform that align the input pattern to the input points. | ||
| outPatternSkeleton | AvlNet.INullable<System.Collections.Generic.List<AvlNet.Segment2D>> | The skeleton of the aligned input pattern points. This parameter cannot be null. |
