Description

dist_rectangle2_contour_points_xlddist_rectangle2_contour_points_xlddist_rectangle2_contour_points_xldDistRectangle2ContourPointsXldDistRectangle2ContourPointsXld 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_xldfit_rectangle2_contour_xldFitRectangle2ContourXldFitRectangle2ContourXld 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_xldfit_rectangle2_contour_xldFitRectangle2ContourXldFitRectangle2ContourXld.
