在Python中显示jpg图像的网格

pip install pillow

from PIL import Image, ImageDraw

# 打开图像
image = Image.open('image.jpg')

# 创建绘图对象
draw = ImageDraw.Draw(image)

# 获取图像的宽度和高度
width, height = image.size

# 定义网格的行数和列数
rows = 10
cols = 10

# 计算每个网格的宽度和高度
grid_width = width // cols
grid_height = height // rows

# 绘制网格线
for i in range(1, cols):
    x = i * grid_width
    draw.line([(x, 0), (x, height)], fill='red')

for i in range(1, rows):
    y = i * grid_height
    draw.line([(0, y), (width, y)], fill='red')

# 显示图像
image.show()
