如何使用枕头操作discord.py上的图像？

pip install Pillow discord.py

import discord
from PIL import Image
import io

# 创建一个 Discord 客户端实例
client = discord.Client()

# 当客户端准备好时触发
@client.event
async def on_ready():
    print(f'已登录为 {client.user}')

# 定义一个命令来处理并发送图像
@client.command()
async def resize_image(ctx, url: str, size: int = 256):
    # 从 URL 下载图像
    async with ctx.channel.typing():
        async with aiohttp.ClientSession() as session:
            async with session.get(url) as resp:
                if resp.status == 200:
                    image_data = await resp.read()
                else:
                    await ctx.send("无法下载图像。")
                    return

    # 使用 Pillow 打开图像
    image = Image.open(io.BytesIO(image_data))

    # 调整图像大小
    resized_image = image.resize((size, size))

    # 将图像保存到内存中的 BytesIO 对象
    buffer = io.BytesIO()
    resized_image.save(buffer, format='PNG')
    buffer.seek(0)

    # 发送处理后的图像到 Discord
    file = discord.File(buffer, filename='resized_image.png')
    await ctx.send(file=file)

# 运行客户端
client.run('YOUR_DISCORD_BOT_TOKEN')

pip install aiohttp
