The polygon coordinates of shape (N, 2) where N is the number of points. Returns ------- mask : 2-D ndarray of type 'bool'. The mask that corresponds to the input polygon. Notes ----- This function does not do any border checking, so that all the vertices need to be within the given shape. Examples -------- >>> image_shape = (128, 128) >>> polygon = np.array([[60, 100], [100, 40], [40, 40]]) >>> mask = polygon2mask(image_shape, polygon) >>> mask.shape (128, 128) )dtypeT)npasarrayTrpolygonzerosbool) image_shapervertex_row_coordsvertex_col_coordsfill_row_coordsfill_col_coordsmaskrA/tmp/pip-target-vg8gfxp4/lib/python/skimage/draw/_polygon2mask.py polygon2masks   r)numpyrrrrrrrs
