如何将图像转换为Base64字符串，并转换回图像，保存为天蓝色斑点

import base64

# 读取图像文件
with open('image.jpg', 'rb') as image_file:
    image_data = image_file.read()

# 将图像数据编码为Base64字符串
base64_string = base64.b64encode(image_data).decode('utf-8')

# 将Base64字符串保存为天蓝色斑点
with open('天蓝色斑点.txt', 'w') as output_file:
    output_file.write(base64_string)

import base64

# 从天蓝色斑点文件中读取Base64字符串
with open('天蓝色斑点.txt', 'r') as input_file:
    base64_string = input_file.read()

# 解码Base64字符串为图像数据
image_data = base64.b64decode(base64_string)

# 将图像数据保存为图像文件
with open('image.jpg', 'wb') as output_file:
    output_file.write(image_data)
