Name
dist_rectangle2_contour_points_xldT_dist_rectangle2_contour_points_xldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXld — Compute the distances of all contour points to a rectangle.
Signature

Description
dist_rectangle2_contour_points_xlddist_rectangle2_contour_points_xldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXld determines the Euclidean
distances between the points of a contour ContourContourContourContourcontour and a
rectangle of arbitrary orientation specified by the center
(RowRowRowRowrow, ColumnColumnColumnColumncolumn), the orientation PhiPhiPhiPhiphi, and
the half edge lengths Length1Length1Length1Length1length1 and Length2Length2Length2Length2length2. The
angle PhiPhiPhiPhiphi must be given in radians and specifies the angle
between the horizontal axis and the edge with the half length
Length1Length1Length1Length1length1 in the mathematically positive direction
(counterclockwise).
Depending on the processing used to create ContourContourContourContourcontour, the
start and end points of a contour may contain positional errors. In
this case, the operator fit_rectangle2_contour_xldfit_rectangle2_contour_xldFitRectangle2ContourXldFitRectangle2ContourXldFitRectangle2ContourXld is
typically called with the parameter ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPoints set
to a value greater than zero to exclude points at the beginning and
the end of the contour from the computation. To compute the
distances of the same set of points as used in the fitting process,
ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPoints should be set to the same value as in
fit_rectangle2_contour_xldfit_rectangle2_contour_xldFitRectangle2ContourXldFitRectangle2ContourXldFitRectangle2ContourXld.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
