粉色框是当前页面，橙色框是鼠标经过，红色框是按下按钮，灰色按钮是其他页面的效果；
存储标识可以用来识别页面是否存储：例如当前页面已经保存用蓝色，未保存用红色，其他页面已经保存用灰色，未保存用淡红色。

首先导入模块

将定义好的Notebook应用到tk窗口，并添加存储标识，不需要的删除即可

上面代码中的base64编码的字符串，可以用下面代码获取，要用gif格式文件转换，传入文件路径即可。

from PIL import Image
import base64, io
def bmp_to_base64(img_path):"将gif图片转为base64编码的字符串"# 打开图片img = Image.open(img_path)# 将图片数据转为字节流byte_arr = io.BytesIO()img.save(byte_arr, format='GIF')img_bytes = byte_arr.getvalue()# 将字节流转为base64编码的字符串base64_str = base64.b64encode(img_bytes).decode()return base64_str
print (bmp_to_base64('gif文件路径'))
