你如何裁剪出一个圆形的图片，而枕头是不和谐的.py

Question

所以我正在尝试制作一个"通缉"；命令，我的机器人将用户的化身图像放置在想要的海报上。我能够让命令生效，但我在尝试将他们的头像裁剪成圆形时遇到了一些麻烦。这是我的代码：

@bot.command(aliases=['Wanted'])
async def wanted(ctx,*, user: discord.Member = None):
async with ctx.typing():
if user == None:
user = ctx.author
wanted = Image.open("wanted.png")

asset = user.avatar_url_as(size=128)
data = BytesIO(await asset.read())
pfp = Image.open(data)
bigsize = (asset.size[0] * 3, asset.size[1] * 3)
mask = Image.new('L', bigsize, 0)
draw = ImageDraw.Draw(mask) 
draw.ellipse((0, 0) + bigsize, fill=255)
mask = mask.resize(asset.size, Image.ANTIALIAS)
asset.putalpha(mask)
pfp = pfp.resize((682,682))
output = ImageOps.fit(asset, mask.size, centering=(0.5, 0.5))
output.putalpha(mask)

wanted.paste(pfp,(280,480))
wanted.save("profile.png")
await ctx.send(file=discord.File("profile.png"))

这是我得到的错误：

Traceback (most recent call last):
File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 903, in invoke
await ctx.command.invoke(ctx)

这是抱怨，因为根据文档，DiscordAsset对象没有属性size。

您要使用的是具有您要查找的size属性的PIL Image对象。这可以通过稍微更改代码来完成：

asset = user.avatar_url_as(size=128)
data = BytesIO(await asset.read())
pfp = Image.open(data)
# Instead of using asset.size, we use pfp.size.  pfp is a PIL Image object
# that has the size attribute.
bigsize = (pfp.size[0] * 3, pfp.size[1] * 3)
