When rounding coordinates for `line_nd`, we want coordinates that are less than 1 apart (always the case, by design) to remain less than one apart. However, NumPy rounds values to the nearest *even* integer, so: >>> np.round([0.5, 1.5, 2.5, 3.5, 4.5]) array([0., 2., 2., 4., 4.]) So, for our application, we detect whether the above case occurs, and use ``np.floor`` if so. It is sufficient to detect that the first coordinate falls on 0.5 and that the second coordinate is 1.0 apart, since we assume by construction that the inter-point distance is less than or equal to 1 and that all successive points are equidistant. Parameters ---------- coords : 1D array of float The coordinates array. We assume that all successive values are equidistant (``np.all(np.diff(coords) = coords[1] - coords[0])``) and that this distance is no more than 1 (``np.abs(coords[1] - coords[0]) <= 1``). Returns ------- rounded : 1D array of int The array correctly rounded for an indexing operation, such that no successive indices will be more than 1 apart. Examples -------- >>> coords0 = np.array([0.5, 1.25, 2., 2.75, 3.5]) >>> _round_safe(coords0) array([0, 1, 2, 3, 4]) >>> coords1 = np.arange(0.5, 8, 1) >>> coords1 array([0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5]) >>> _round_safe(coords1) array([0, 1, 2, 3, 4, 5, 6, 7]) rg?)lennpfloorroundastypeint)coords_round_functions T/var/www/html/land-doc-ocr/venv/lib/python3.13/site-packages/skimage/draw/draw_nd.py _round_safers[R 6{Q6!9q=C/F1Iq 4IQ4N(((( 6 " ) )# ..FT)endpointintegerc [R"U5n[R"U5n[[R"[R"[R "X- 5555nU(aUS- n[R "XXBS9RnU(aG[[U55Hn[XVSS245XVSS24'M UR[5n[U5$)aDraw a single-pixel thick line in n dimensions. The line produced will be ndim-connected. That is, two subsequent pixels in the line will be either direct or diagonal neighbors in n dimensions. Parameters ---------- start : array-like, shape (N,) The start coordinates of the line. stop : array-like, shape (N,) The end coordinates of the line. endpoint : bool, optional Whether to include the endpoint in the returned line. Defaults to False, which allows for easy drawing of multi-point paths. integer : bool, optional Whether to round the coordinates to integer. If True (default), the returned coordinates can be used to directly index into an array. `False` could be used for e.g. vector drawing. Returns ------- coords : tuple of arrays The coordinates of points on the line. Examples -------- >>> lin = line_nd((1, 1), (5, 2.5), endpoint=False) >>> lin (array([1, 2, 3, 4]), array([1, 1, 2, 2])) >>> im = np.zeros((6, 5), dtype=int) >>> im[lin] = 1 >>> im array([[0, 0, 0, 0, 0], [0, 1, 0, 0, 0], [0, 1, 0, 0, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 0, 0]]) >>> line_nd([2, 1, 1], [5, 5, 2.5], endpoint=True) (array([2, 3, 4, 4, 5]), array([1, 2, 3, 4, 5]), array([1, 1, 2, 2, 2])) r)numrN) rasarrayr ceilmaxabslinspaceTrangerrr tuple)startstoprrnpointsr dims r line_ndr 4sV JJu E ::d D"''"&& !5678G1  [[' E G GFU$C(Q8F6N%s# =r)numpyrrr rr r#s-/`&+D8r
