更改脚本中图像的大小？

from PIL import Image

def resize_image(input_image_path, output_image_path, size):
    original_image = Image.open(input_image_path)
    width, height = original_image.size
    print(f"The original image size is {width} wide x {height} tall")

    resized_image = original_image.resize(size)
    width, height = resized_image.size
    print(f"The resized image size is {width} wide x {height} tall")

    resized_image.save(output_image_path)

# 调用示例
input_image = "input.jpg"
output_image = "output.jpg"
new_size = (800, 600)
resize_image(input_image, output_image, new_size)
