如何在SwiftUI中为图片设置固定大小?目前我的图片真的很大

目前,我具有以下结构:

 // @route  POST api/auth
 // @desc   Authenticate user and get token
 // @access Public
 router.post(
 "/",
 [
 check("email", "Please include a valid email").isEmail(),
 check("password", "Please is required").exists()
 ],
 async (req, res) => {
 const errors = validationResult(req);

 // send back any errors
 if (!errors.isEmpty()) {
      return res.status(400).json({
      errors: errors.array()
      });
 }

 const { email, password } = req.body;

 try {
      // check if user exists, send error if so
      let user = await User.findOne({ email });

      if (!user) {
      return res
           .status(400)
           .json({ errors: [{ msg: "Invalid credentials" }] });
      }

      const isMatch = await bcrypt.compare(password, user.password);

      if (!isMatch) {
      return res
           .status(400)
           .json({ errors: [{ msg: "Invalid credentials" }] });
      }
      // return jsonwebtoken so that way they're logged in right
      // away, without having to log in after registering
      const payload = {
      user: {
           id: user.id
      }
      };

      jwt.sign(
      payload,
      config.get("jwtSecret"),
      {
           expiresIn: process.env.PORT ? 3600 : 36000
      },
      (err, token) => {
           if (err) throw err;

           console.log(token); // prints token!

           return res.json({ token });
      }
      );
 } catch (err) {
      console.log(err);
      res.status(500).send("Server error");
 }
 }
 );

一种方法是通过

profileImage.resizable().frame(width: 50, height: 50)

There are multiple ways to set fixed size to Image

1) Image("yourImage").frame(width: 25, height: 25, alignment: .center)

2) Image("yourImage").resizable().frame(width: 25, height: 25, alignment: .center)
3) Image("yourImage").frame(width: 25, height: 25, alignment: .center).clipped()

Attached the screenshots for all.
