WebSo, due to a limited raster resolution, the moments computed for a contour are slightly different from the moments computed for the same rasterized contour. Since the contour moments are computed using Green formula, you may get seemingly odd results for contours with self-intersections, e.g. a zero area (m00) for butterfly-shaped contours.
