在Python中逐行写入拼花

from PIL import Image

def mosaic(image_path, block_size):
    # 打开图像
    image = Image.open(image_path)
    width, height = image.size

    # 计算拼花后的图像大小
    mosaic_width = width // block_size
    mosaic_height = height // block_size

    # 创建新的图像对象
    mosaic_image = Image.new('RGB', (mosaic_width, mosaic_height))

    # 逐行写入拼花
    for y in range(mosaic_height):
        for x in range(mosaic_width):
            # 计算当前拼花块的位置
            block_x = x * block_size
            block_y = y * block_size

            # 获取拼花块的颜色
            block_color = image.getpixel((block_x, block_y))

            # 将拼花块的颜色填充到新图像中
            for i in range(block_size):
                for j in range(block_size):
                    mosaic_image.putpixel((x * block_size + i, y * block_size + j), block_color)

    # 保存拼花后的图像
    mosaic_image.save('mosaic.jpg')

# 调用示例
mosaic('image.jpg', 10)
