Python 曼德布罗特集&x27；撕裂'；在不同的X和Y值下

我的代码中最紧迫的问题是，当我将X和Y尺寸更改为例如X=501，Y=500时，mandelbrot将完全撕裂（见图）。X轴和Y轴也反转

我的目标是获得与此类似的结果，根据我所能收集到的信息，我应该创建一个以原点为中心的坐标图

任何帮助都将不胜感激

from tkinter import *
import numpy as np
from numba import jit

X = 500
Y = 500

maxIter = 500 

minR = -3
minI = -2
maxR = 2
maxI = 2

@jit
def mandelbrot_set(minR,maxR,minI,maxI,X,Y,maxIter):
    r1 = np.linspace(minR, maxR, X)
    r2 = np.linspace(minI, maxI, Y)
    return (r1,r2,[mandelbrot(complex(r, i),maxIter) for r in r1 for i in r2])

@jit
def mandelbrot(c,max):
    z = c
    for n in range(max):
        if abs(z) > 4:
            return n
        z = z*z + c
    return 255

set = mandelbrot_set(minR,maxR,minI,maxI,X,Y,maxIter)

window = Tk()
canvas = Canvas(window, width = X, height = Y, bg = "#FFFFFF", highlightthickness=0)
canvas.pack()
img = PhotoImage(width = X, height = Y)
canvas.create_image((0, 0), image = img, state = "normal", anchor = NW)

hexstring = ""
counter = 0
for imaginary in set[1]:
    hexstring += "{ "
    for real in set[0]:
        if set[2][counter] == 0:
            hexstring += "#000000 "
        else:
            hexstring += "#" + "%02x" % set[2][counter] + "%02x" % set[2][counter] + "%02x" % set[2][counter] + " "
        counter += 1
    hexstring += "} "

img.put(hexstring)
window.mainloop()

正常：

破碎的曼德尔布罗特：

要解决撕裂问题，您必须将代码中的

set[0]

替换为

set[1]

for imaginary in set[0]: # before set[1]
    hexstring += "{ "
    for real in set[1]:  # before set[0]

代码：

---

要旋转图像，必须将r2中r的

替换为r1中i的

 [mandelbrot(complex(r, i), maxIter) for i in r2 for r in r1]

但是保持先前的状态

for imaginary in set[1]: # before set[1]
    hexstring += "{ "
    for real in set[0]:  # before set[0]

代码：

您的问题与tkinter无关-问题在于您的算法。将函数中的值与链接中代码生成的值进行比较，您将看到哪里出错了。我将首先检查
linspace
中的值。不久前，如果您有兴趣，我将在GLSL中对其进行编码，请参见：
for imaginary in set[1]: # before set[1]
    hexstring += "{ "
    for real in set[0]:  # before set[0]
