Python 如何在Discord.py中使用枕头将图像裁剪成圆形？

如何在Discord.py中使用枕头将图像裁剪成圆形

我当前的代码：

@client.event
async def on_member_join(member : discord.Member):
    welcome = Image.open('Welcome.jpg')
    
    asset = member.avatar_url_as(size = 128)
    data = BytesIO(await asset.read())
    pfp = Image.open(data)
    pfp = pfp.resize((500, 500))
    welcome.paste(pfp, (657, 257))
    welcome.save("profile.jpg")

试试这个

import numpy as np
from PIL import Image, ImageDraw

@client.event
async def on_member_join(member : discord.Member):
    welcome = Image.open('Welcome.jpg')
    
    asset = member.avatar_url_as(size = 128)
    data = BytesIO(await asset.read())
    img=Image.open(data).convert("RGB")
    npImage=np.array(img)
    h,w=img.size
    
    alpha = Image.new('L', img.size,0)
    draw = ImageDraw.Draw(alpha)
    draw.pieslice([0,0,h,w],0,360,fill=255)
    npAlpha=np.array(alpha)
    npImage=np.dstack((npImage,npAlpha))
    pfp = Image.fromarray(npImage)
    welcome.paste(pfp, (657, 257))
    welcome.save("profile.jpg")
    

试试这个

import numpy as np
from PIL import Image, ImageDraw

@client.event
async def on_member_join(member : discord.Member):
    welcome = Image.open('Welcome.jpg')
    
    asset = member.avatar_url_as(size = 128)

    draw.pieslice([0,0,h,w],0,360,fill=255)
    npAlpha=np.array(alpha)
    npImage=np.dstack((npImage,npAlpha))
    pfp = Image.fromarray(npImage)
    welcome.paste(pfp, (657, 257))
    welcome.save("profile.jpg")

你应该解释一下每一步都发生了什么。提问者无法学习如何正确地进行提问。我理解@CloudGreat！其他有同样问题的人可能会从解释中受益。你应该解释一下每一步都发生了什么。提问者无法学习如何正确地进行提问。我理解@CloudGreat！不过，其他有同样问题的人可能会从解释中受益。
