image_list.py 里提取像素方式是光栅扫描，即按行扫描，从左到右，从上到下。
image_list.txt 内容是一个二维列表，即灰度图（模式 L），且外层是行，内层是列。
结构如下：
[
[ (0,0), (1,0), (2,0) ], # 第 1 行 (Top)
[ (0,1), (1,1), (2,1) ], # 第 2 行
[ (0,2), (1,2), (2,2) ] # 第 3 行 (Bottom)
]

还原脚本：

from PIL import Image
import jsonwith open('image_list.txt', 'r', encoding='utf-8') as f:image_list = json.load(f)# 列表外层长度对应行，也就是图像的高 h
# 列表内层长度对应列，也就是图像的宽 w
h, w = len(image_list), len(image_list[0])
p = image_list[0][0]
mode = 'L' if isinstance(p, int) else 'RGBA' if len(p) == 4 else 'RGB'# PIL (Pillow) 库遵循计算机图形学的标准坐标系 (列，行)
img = Image.new(mode, (w, h))
for x in range(h):          # 遍历每一行for y in range(w):      # 遍历每一列pixel_value = image_list[y][x]img.putpixel((y, x), pixel_value)
img.save('restored.png')print(f"还原成功：{w}x{h} ({mode}) -> restored.png")
