使用 Pyglet 将 gif 缩放到屏幕

Question

任何人都可以清楚地说明我的代码，为什么当我尝试将我的 gif 缩放到全屏时，一半的屏幕是白色的，而另一个是 gif（动画）？这是使用 Pyglet python 模块。

这是我的代码以及问题的图片：

'Load animation'
animation = pyglet.image.load_animation('Goober#13427G.gif')
animSprite = pyglet.sprite.Sprite(animation)

# 'Scale image to screen *harcoded*'
# animSprite.scale_x = 3.2
# animSprite.scale_y = 1.71

' Get display and create a fullscreen window while scaling gif to screen'
display = pyglet.canvas.Display()
screen = display.get_screens()

H_ratio = max(animSprite.height, screen[1].height) / min(animSprite.height, screen[1].height)
W_ratio = max(animSprite.width, screen[1].width) / min(animSprite.width, screen[1].width)

animSprite.scale = min(H_ratio, W_ratio) 

window = pyglet.window.Window(width=screen[1].width, height=screen[1].height, fullscreen=True, screen=screen[1])

r, g, b, alpha = 1, 1, 1, .5
pyglet.gl.glClearColor(r, g, b, alpha)


@window.event
def on_draw():
    window.clear()
    animSprite.draw()


pyglet.app.run()
```[Gif with second half of screen to the right is white][1]

尝试缩放每个轴。

animSprite.scale_x = W_ratio
animSprite.scale_y = H_ratio
