如何在python中调整图像大小

from PIL import Image

image = Image.open("image.jpg")

new_size = (500, int(image.size[1] * (500 / image.size[0])))
resized_image = image.resize(new_size)

resized_image.save("resized_image.jpg", "JPEG")

from PIL import Image

def resize_image(input_image_path, output_image_path, size):
    image = Image.open(input_image_path)
    new_size = (size[0], int(image.size[1] * (size[0] / image.size[0])))
    resized_image = image.resize(new_size)
    resized_image.save(output_image_path, "JPEG")

# 调用函数进行图像大小调整
resize_image("image.jpg", "resized_image.jpg", (500, 500))
