在JPG文件中嵌入数据，而不更改python中的图像

from PIL import Image

def embed_data_in_jpg(image_path, data):
    image = Image.open(image_path)
    pixels = image.load()

    # 将数据转换为二进制字符串
    data_bin = ''.join(format(ord(c), '08b') for c in data)

    # 检查数据是否过大，超过图像容量则抛出异常
    if len(data_bin) > image.size[0] * image.size[1] * 3:
        raise ValueError("Data size exceeds image capacity")

    # 遍历图像像素，将数据嵌入到LSB中
    data_index = 0
    for y in range(image.size[1]):
        for x in range(image.size[0]):
            r, g, b = pixels[x, y]
            if data_index < len(data_bin):
                # 修改LSB
                r = (r & 0xFE) | int(data_bin[data_index])
                data_index += 1
            pixels[x, y] = (r, g, b)

    # 保存修改后的图像
    image.save("embedded_image.jpg")

# 调用示例
embed_data_in_jpg("original_image.jpg", "Hello, World!")
