使用Python批量修改图片的尺寸

一次性批量修改图片的尺寸，png，jpg，jpeg，bmp等格式都兼容，简单有效。

import cv2
import os


def resize(input_image_path, output_image_path, new_size):
    # 遍历文件夹中的所有图片
    for image_name in os.listdir(input_image_path):
        if image_name.lower().endswith(('.png', '.jpg', '.jpeg', '.bmp')):
            try:
                # 读取图片
                img = cv2.imread(os.path.join(input_image_path, image_name))
                if img is not None:
                    # 修改图片尺寸
                    img = cv2.resize(img, new_size)
                    # 保存到输出文件夹
                    cv2.imwrite(os.path.join(output_image_path, image_name), img)
                else:
                    print(f"无法读取文件 {image_name}。")
            except Exception as e:
                print(f"处理文件 {image_name} 时发生错误：{e}")


if __name__ == '__main__':
    # 输入图片的文件夹路径
    input_image_path = r'E:\1'
    # 输出图片的文件夹路径
    output_image_path = r'E:\1\1'
    # 需要修改的图片尺寸
    new_size = (640, 640)

    resize(input_image_path, output_image_path, new_size)
