如何调整 URL 中的图像大小？

Question

imagelist=[]
with open("imagelink.txt") as url:
for url2 in url:
    if url2.strip():
        raw_data= urllib.request.urlopen(url2.strip()).read()
        im = ImageTk.PhotoImage(data=raw_data)
        result = maintext.image_create(0.0, image=im)
        imagelist.append(im)

So this is my code i am opening a image URL and displaying the image in a text box,so how do I resize the image from the URL I tried using resize function but it says photo image doesn't have resize function.So how do我调整 URL 图像的大小？

您可以使用PIL.Image.open()和io.BytesIO()打开检索到的图像并调整其大小：

import io
from PIL import Image, ImageTk
...
imagelist=[]
with open("imagelink.txt") as url:
    for url2 in url:
        url2 = url2.strip()
        if url2:
            raw_data = urllib.request.urlopen(url2).read()
            # open the image and resize
            im = Image.open(io.BytesIO(raw_data)).resize((300,100))
            im = ImageTk.PhotoImage(im)
            #im = ImageTk.PhotoImage(data=raw_data)
            result = maintext.image_create(0.0, image=im)
            imagelist.append(im)
