描述
dist_rectangle2_contour_points_xlddist_rectangle2_contour_points_xldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXlddist_rectangle2_contour_points_xld determines the Euclidean
distances between the points of a contour ContourContourContourContourcontourcontour and a
rectangle of arbitrary orientation specified by the center
(RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn), the orientation PhiPhiPhiPhiphiphi, and
the half edge lengths Length1Length1Length1Length1length1length_1 and Length2Length2Length2Length2length2length_2. The
angle PhiPhiPhiPhiphiphi must be given in radians and specifies the angle
between the horizontal axis and the edge with the half length
Length1Length1Length1Length1length1length_1 in the mathematically positive direction
(counterclockwise).
Depending on the processing used to create ContourContourContourContourcontourcontour, the
start and end points of a contour may contain positional errors. In
this case, the operator fit_rectangle2_contour_xldfit_rectangle2_contour_xldFitRectangle2ContourXldFitRectangle2ContourXldFitRectangle2ContourXldfit_rectangle2_contour_xld is
typically called with the parameter ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPointsclipping_end_points 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,
ClippingEndPointsClippingEndPointsClippingEndPointsClippingEndPointsclippingEndPointsclipping_end_points should be set to the same value as in
