The operator dist_ellipse_contour_points_xlddist_ellipse_contour_points_xldDistEllipseContourPointsXlddist_ellipse_contour_points_xldDistEllipseContourPointsXldDistEllipseContourPointsXld determines the
distances between points of a contour ContourContourContourContourContourcontour and an ellipse
specified by the center (RowRowRowRowRowrow, ColumnColumnColumnColumnColumncolumn), the
orientation of the main axis PhiPhiPhiPhiPhiphi,
the length of the larger half axis Radius1Radius1Radius1Radius1Radius1radius1, and the
length of the smaller half axis Radius2Radius2Radius2Radius2Radius2radius2.
The distance measure is the geometric distance, sometimes also called
orthogonal distance. The distances DistancesDistancesDistancesDistancesDistancesdistances are returned for
all points of the contour.
Normally, the distance is a positive value. In this case
DistanceModeDistanceModeDistanceModeDistanceModeDistanceModedistanceMode equal to 'unsigned'"unsigned""unsigned""unsigned""unsigned""unsigned" must be chosen.
If this option is switched to 'signed'"signed""signed""signed""signed""signed" the distances can take
positive or negative sign, depending on whether the contour points lie
outside or inside the ellipse respectively.
Because of artefacts in the preprocessing, the start and end points
of a contour might be faulty. In this case, the operator
fit_ellipse_contour_xldfit_ellipse_contour_xldFitEllipseContourXldfit_ellipse_contour_xldFitEllipseContourXldFitEllipseContourXld is typically called with the parameter
ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPoints set to a value greater than zero to exclude
points at the beginning and the end of the contour from the computation.
In order to get the geometric distances of the same set of points as used
in the fitting process ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPoints should take
the same value.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

dist_ellipse_contour_points_xlddist_ellipse_contour_points_xldDistEllipseContourPointsXlddist_ellipse_contour_points_xldDistEllipseContourPointsXldDistEllipseContourPointsXld returns 2 (H_MSG_TRUE) if all parameter
values are correct. If necessary, an exception is raised.
