Question

这是我在 python 中的边界填充 pgm bt 它只填充了边界的一半

def is_equal(a, b):
    _equal = a[0]==b[0] and a[1]==b[1] and a[2]==b[2]
    return _equal

def boundary_fill(src, x, y, fill_color, boundary_color):
    print "x , y ", x, y
    try:
        color_at_xy = src[y, x]
    except IndexError:
        return
    if not is_equal(color_at_xy,fill_color) and not is_equal(color_at_xy,boundary_color):
        src[y, x] = fill_color
        #boundary_fill(src, x + 1, y, fill_color, boundary_color)
        boundary_fill(src, x - 1, y, fill_color, boundary_color)
        boundary_fill(src, x, y + 1, fill_color, boundary_color)
        boundary_fill(src, x, y - 1, fill_color, boundary_color)

File "as.py", line 5, in is_equal
    _equal = a[0]==b[0] and a[1]==b[1] and a[2]==b[2]
RuntimeError: maximum recursion depth exceeded in cmp
