PPT 倒計時時鐘，用 GIF 動畫實作，可直接使用 -- 附 Python 實作代碼

在上課時，有時需要顯示一個倒計時時鐘，讓學生做題。 PPT 沒有簡單有效的方法實作倒計時時鐘，參考了多個方案，最終決定采用 GIF 動畫來實作。

這樣使用起來很簡單，隻要把事先做好的各個時長的倒計時動畫按需拖入 PPT 即可。

下面這個是一分鐘的倒計時動畫

已生成好了 1~15 分鐘倒計時，可以點下面連結下載下傳使用，圖檔尺寸是 900x700

動畫是用 Python 代碼生成的，如果想改 UI, 可以修改下面代碼來重新生成

    imageio.mimsave(gif_file, filenames, duration=1, loop=1)

時間匆忙，代碼沒有寫注釋，也沒有優化。等有時間了再優化

代碼中用到了一些圖檔檔案，可以下載下傳代碼打包版本，裡面有。代碼打包下載下傳位址：
