label start():

    $ pil_image_resized = resize( 1280, 720, pil_image)
    $ tk_image = ImageTk.PhotoImage(pil_image_resized)

到网上找了下，发现上面这段代码
但是一运行就报cannot import name_imaging，但我在pycharm中跑了下又没任何问题
有没有大佬知道什么问题

随便放在哪都行，你新建个class.rpy文件放在里面就行了

@楼主。非常感谢楼主。不过还是无法使用，需要对代码里面的内容根据实际情况修改一下吗？改哪里？头三句不能读，我每句前面打了#，还是显示错误：说7，16，38行都有错。

从init python往下复制就行了，前面的[mw_shl_code=renpy,true]一大堆不要管它,添加图片那你要根据自己的实际情况添加
