文件上傳采用的是flask-uploads插件，添加了一個改變文件名的函數(shù)change_filename，現(xiàn)在希望可以增加一個縮放尺寸的函數(shù)，自定義寬高，只保存縮放后的圖片，目前代碼如下：@admin.route('/post/new', methods=['GET', 'POST'])@login_required
def post_new():
form = PostForm() if form.validate_on_submit():
title = form.title.data
photo_filename = change_filename(form.photo.data.filename)
photo = photos.save(form.photo.data, name=photo_filename)
post = Post(title=title, photo=photo)
db.session.add(post)
db.session.commit() return redirect(url_for('admin.post_manage')) return render_template('admin/post_new.html', form=form)請教大蝦們應(yīng)該怎么寫！感謝！

from PIL import Image
old_file = "1.jpg"new_file = "1_t.jpg"sImg = Image.open(old_file)
w, h = sImg.sizeprint(w,h)
dImg = sImg.resize((int(w / 2), int(h / 2)), Image.ANTIALIAS)
dImg.save(new_file)print("轉(zhuǎn)換后尺寸")
sImg_t = Image.open(new_file)
w, h = sImg_t.sizeprint(w,h)添加回答
