我正试图添加一个白色的背景，我的文字与moviepy和我想添加一个黑色的中风线，这个背景。
目前我有

for step in data["steps"]:
        image_file = f"image{str(idx)}.png"  # Replace with your actual image file names
        text1 = TextClip(wrap_text(step["text1"]), fontsize=48, color='black', font='Stanberry.ttf')
        text2 = TextClip(wrap_text(step["text2"]), fontsize=48, color='black', font='Stanberry.ttf')

        imageDuration = 5
        videoDuration += imageDuration
        image = ImageClip(image_file).set_duration(imageDuration).resize(height=1920).resize(width=1080).margin(5, color=(0, 0, 0))

        text1_bg = ColorClip(size=(text1.size[0] + 20, text1.size[1] + 20), color=(255, 255, 255)).set_duration(imageDuration)
        text2_bg = ColorClip(size=(text2.size[0] + 20, text2.size[1] + 20), color=(255, 255, 255)).set_duration(imageDuration)

        text1_pos = ('center', 50)
        text2_pos = ('center', image.size[1] - text2.size[1] - 50)

        text1 = text1.set_position(text1_pos).set_duration(imageDuration)
        text2 = text2.set_position(text2_pos).set_duration(imageDuration)

        composite = CompositeVideoClip([image, text1_bg, text1.set_start(0), text2_bg, text2.set_start(0)], size=(1080, 1920))
        images.append(composite)
