Python GIF Tutorial: Create Animations

To generate GIF animations in Python, you can use the PIL (Python Imaging Library) library. Here is a simple example code demonstrating how to use the PIL library to create a basic animation.

from PIL import Image, ImageSequence

# 创建一个新的GIF动画
frames = []

# 循环创建帧
for i in range(10):
    # 创建一个新的图像帧
    frame = Image.new('RGB', (200, 200), (255, 255, 255))
    
    # 在每个帧上绘制一些图形或文本
    # 这里只是简单地绘制一个红色的矩形
    draw = ImageDraw.Draw(frame)
    draw.rectangle([(50, 50), (150, 150)], fill=(255, 0, 0))
    
    # 将帧添加到动画帧列表中
    frames.append(frame)
    
# 保存动画
frames[0].save('animation.gif', save_all=True, append_images=frames[1:], optimize=False, duration=100, loop=0)

In this example, we first import the Image and ImageSequence modules from the PIL library. Then, we create an empty list called frames to store frames.

Creating frames using a loop. For each frame, a new image frame is created and some graphics or text is drawn on it. In this example, we simply drew a red rectangle.

Finally, we use the save() function to save the frames as a GIF animation file. The parameters of the save() function are set as follows: save_all=True to save all frames, append_images=frames[1:] to add subsequent frames after the first one, optimize=False to not optimize, duration=100 to set the playback time for each frame as 100 milliseconds, and loop=0 for looping playback.

After running the above code, it will generate a GIF animation file named animation.gif, which includes a simple animation of 10 frames of red rectangles.
