如何在Kivy中从数组更新纹理？

from kivy.app import App
from kivy.uix.widget import Widget
from kivy.graphics.texture import Texture
from kivy.clock import Clock

class MyWidget(Widget):
    def __init__(self, **kwargs):
        super(MyWidget, self).__init__(**kwargs)
        self.texture = Texture.create(size=(100, 100))

    def update_texture(self, dt):
        # 在这里更新纹理的数据
        # 假设有一个名为"image_data"的数组包含了新的纹理数据
        self.texture.blit_buffer(image_data, colorfmt='rgb', bufferfmt='ubyte')
        self.texture.flip_vertical()  # 如果需要翻转纹理，请取消注释此行

class MyApp(App):
    def build(self):
        widget = MyWidget()
        Clock.schedule_interval(widget.update_texture, 1.0 / 60.0)  # 每秒钟60帧
        return widget

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