from kivy.app import App
from kivy.uix.image import Image
from kivy.uix.boxlayout import BoxLayout

class MyBoxLayout(BoxLayout):
    pass

class MyBoxLayout(BoxLayout):
    def __init__(self, **kwargs):
        super(MyBoxLayout, self).__init__(**kwargs)
        image = Image(source='path_to_image', allow_stretch=True, keep_ratio=True)
        image.rotation = 90  # 设置旋转角度为90度
        self.add_widget(image)

class MyApp(App):
    def build(self):
        return MyBoxLayout()

if __name__ == '__main__':
    MyApp().run()
