    def resize( w_box, h_box, pil_image): #参数是:要适应的窗口宽、高、Image.open后的图片
      w, h = pil_image.size #获取图像的原始大小

label start():
    $ pil_image = Image.open(r"E:\bcrj\Ren'Py\ceshi\game\images\1_1.png")
    $ pil_image_resized = resize( 1280, 720, pil_image)
    $ tk_image = ImageTk.PhotoImage(pil_image_resized)
    show tk_image

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
