Parameters ---------- image_shape : tuple of size 2 The shape of the mask. polygon : (N, 2) array_like The polygon coordinates of shape (N, 2) where N is the number of points. The coordinates are (row, column). Returns ------- mask : 2-D ndarray of type 'bool' The binary mask that corresponds to the input polygon. See Also -------- polygon: Generate coordinates of pixels inside a polygon. Notes ----- This function does not do any border checking. Parts of the polygon that are outside the coordinate space defined by `image_shape` are not drawn. Examples -------- >>> import skimage as ski >>> image_shape = (10, 10) >>> polygon = np.array([[1, 1], [2, 7], [8, 4]]) >>> mask = ski.draw.polygon2mask(image_shape, polygon) >>> mask.astype(int) array([[0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 1, 1, 1, 1, 1, 1, 0, 0], [0, 0, 1, 1, 1, 1, 1, 0, 0, 0], [0, 0, 0, 1, 1, 1, 1, 0, 0, 0], [0, 0, 0, 1, 1, 1, 0, 0, 0, 0], [0, 0, 0, 0, 1, 1, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]) If vertices / points of the `polygon` are outside the coordinate space defined by `image_shape`, only a part (or none at all) of the polygon is drawn in the mask. >>> offset = np.array([[2, -4]]) >>> ski.draw.polygon2mask(image_shape, polygon - offset).astype(int) array([[0, 0, 0, 0, 0, 0, 1, 1, 1, 1], [0, 0, 0, 0, 0, 0, 1, 1, 1, 1], [0, 0, 0, 0, 0, 0, 0, 1, 1, 1], [0, 0, 0, 0, 0, 0, 0, 1, 1, 1], [0, 0, 0, 0, 0, 0, 0, 0, 1, 1], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]) )ZdtypeT)npZasarrayTrpolygonZzerosbool)Z image_shaperZvertex_row_coordsZvertex_col_coordsZfill_row_coordsZfill_col_coordsmaskr [/home/www/facesmatcher.com/pyenv/lib/python3.10/site-packages/skimage/draw/_polygon2mask.py polygon2masks =  r )numpyrrr r r r r s
