Python龟图像放置

Question

有人知道我怎么把gif图像放在turtle created background上吗。这是在数组中创建的网格布局：

pixels =     [[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]]

pixels.append([0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0])

我无法使gif图像显示在网格上方。网格是背景，a pixel soldier将出现在网格上方

我正在使用海龟库，不能使用pygame库

Answer 1

下面是一个将图像置于海龟绘制的背景之上的示例。我使用了我自己的网格代码，因为你没有提供你的，但它可以是海龟画的任何东西：

from turtle import Screen, Turtle

N = 10  # N by N grid
LENGTH = 30  # each grid element will be LENGTH x LENGTH pixels

def grid(turtle, n, length):
    sign = 1
    for _ in range(2):

        for _ in range(n):
            turtle.forward(length * n)
            turtle.left(sign * 90)
            turtle.forward(length)
            turtle.left(sign * 90)
            sign = 0 - sign

        turtle.forward(length * n)
        [turtle.right, turtle.left][n % 2](90)
        sign = 0 - sign

screen = Screen()
screen.tracer(False)  # because I have no patience
screen.register_shape("Thyrl.gif")

background = Turtle()
background.hideturtle()

background.penup()
background.goto(-N * LENGTH/2, screen.window_height()/2 - N * LENGTH)
background.pendown()

grid(background, N, LENGTH)

foreground = Turtle("Thyrl.gif")
foreground.penup()
foreground.sety(screen.window_height()/2 - N * LENGTH/2)

screen.tracer(True)
screen.exitonclick()

图像需要一个透明的背景才能清晰地显示出来。我还缩小了你的图像，使像素正常大小
