在合并图像和gif(反转(或蓝色)图像) discord.py时遇到问题

from PIL import Image

# 打开图像
image1 = Image.open('path_to_image1.png')
image2 = Image.open('path_to_image2.gif')

# 确保图像模式一致
if image1.mode != image2.mode:
    image2 = image2.convert(image1.mode)

# 合并图像
merged_image = Image.alpha_composite(image1, image2)

# 保存合并后的图像
merged_image.save('merged_image.png')

from PIL import Image, ImageOps

# 打开GIF
gif = Image.open('path_to_gif.gif')

# 处理每一帧
frames = []
for frame in range(0, gif.n_frames):
    gif.seek(frame)
    frame_image = gif.convert('RGBA')
    
    # 反转颜色
    inverted_frame = ImageOps.invert(frame_image)
    
    # 转换为蓝色调
    blue_frame = ImageOps.colorize(inverted_frame, black="blue", white="white")
    
    frames.append(blue_frame)

# 保存处理后的GIF
frames[0].save('processed_gif.gif', save_all=True, append_images=frames[1:], loop=0)

import discord
from discord.ext import commands

bot = commands.Bot(command_prefix='!')

@bot.command()
async def send_image(ctx):
    # 假设你已经处理好了图像并保存为 'merged_image.png'
    with open('merged_image.png', 'rb') as f:
        picture = discord.File(f)
        await ctx.send(file=picture)

bot.run('YOUR_BOT_TOKEN')
