在python中通过重叠图像创建马赛克

from PIL import Image

original_image = Image.open("original.jpg")

mosaic_size = 10  # 马赛克块的大小为10x10像素

mosaic_image = original_image.copy()  # 创建与原始图像相同尺寸的马赛克图像

for y in range(0, original_image.height, mosaic_size):
    for x in range(0, original_image.width, mosaic_size):
        # 获取马赛克块的颜色
        mosaic_color = original_image.getpixel((x, y))
        
        # 将马赛克块内的像素替换为相同的颜色
        for mosaic_y in range(y, y + mosaic_size):
            for mosaic_x in range(x, x + mosaic_size):
                mosaic_image.putpixel((mosaic_x, mosaic_y), mosaic_color)

mosaic_image.save("mosaic.jpg")
