我想将png图片的大小从476x402调整为439x371，我使用了PIL(image)或opencv的调整大小方法，但是，它会损失一些清晰度。调整大小后，图片变得模糊。如何使用 python 调整（缩小）图像而不丢失清晰度？

from skimage import transform, data, io
from PIL import Image
import os
import cv2

infile = 'D:/files/script/org/test.png'
outfile = 'D:/files/script/out/test.png'

''' PIL'''
def fixed_size1(width, height):
    im = Image.open(infile)
    out = im.resize((width, height),Image.ANTIALIAS)
    out.save(outfile)

''' open cv'''
def fixed_size2(width, height):
    img_array = cv2.imread(infile)
    new_array = cv2.resize(img_array, (width, height), interpolation=cv2.INTER_CUBIC)
    cv2.imwrite(outfile, new_array)


def fixed_size3(width, height):
    img = io.imread(infile)
    dst = transform.resize(img, (439, 371))
    io.imsave(outfile, dst)

fixed_size2(371, 439)
