FIL.PointAlongArc
Transforms a point to a coordinate system in which the 'axis' arc is vertical or horizontal.
| Namespace: | FilNet |
|---|---|
| Assembly: | FIL.NET.dll |
Syntax
public static void PointAlongArc ( FilNet.Point2D inPoint, FilNet.Arc2D inAxis, FilNet.Axis inAxisType, float inAxisCoordinate, bool inInverse, out FilNet.Point2D outPoint )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inPoint | FilNet.Point2D | Input point. | ||
| inAxis | FilNet.Arc2D | Input axis arc. | ||
| inAxisType | FilNet.Axis | Y | Type of axis the input axis arc is parallel to. Default value: Y. | |
| inAxisCoordinate | float | 0.0f | Coordinate of the axis arc. Default value: 0.0f. | |
| inInverse | bool | True | Switches to the inverse operation. Default value: True. | |
 | outPoint | FilNet.Point2D | Transformed point. |
Description
This operation transforms a point - inPoint - between two coordinate systems: the one linked with 'axis' arc inAxis and the original one. Direction of this conversion is based on inInverse value:
- if it is true, inPoint is converted to original coordinate system
- if it is false, inPoint is converted from original coordinate system
Coordinate system linked with inAxis is some transformation of the original one, satisfying these conditions:
- 'axis' arc is represented as a straight line
- 'axis' arc is horizontal if inAxisType is set to X or vertical if inAxisType is set to Y
- if inAxisType is set to X, the Y coordinate of 'axis' arc is equal to inAxisCoordinate. If inAxisType is set to Y, the X coordinate of 'axis' arc is equal to inAxisCoordinate

ImageAlongArc performed on the sample image with inAxisType = X and inScanWidth = 50. Point marked with green cross on the output image was calculated by ScanSingleEdge. Original point (marked with blue cross) was calculated using PointAlongArc with inAxisType = X, inAxisCoordinate = 25, inInverse = true and position of detected point. ImageAlongArc and PointAlongArc used the same arc for transformations.
