一、使用说明

1. 确定已经安装python，且版本3.6以上，可以用下面指令查看python版本：python --version

2. 配置环境，第一次使用先配置环境，后面不需要

3. 把要转换的图片放到"img"文件夹下

4. 转换，结果保存在本目录下的新创建的文件夹中

二、配置环境脚本（.bat）

@echo off
chcp 65001 > nulREM Check Python version
python -c "import sys; exit(0) if sys.version_info >= (3, 6) else exit(1)"
IF ERRORLEVEL 1 (echo Your Python version is lower than 3.6. Please upgrade your Python version.echo Upgrade instructions:echo 1. Visit https://www.python.org/downloads/ to download the latest version of Python.echo 2. During installation, make sure to check "Add Python to PATH".pauseexit /b 1
)REM Install required packages
pip install -r .\__pycache__\requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple %*pause

三、转换源码

import os
import sys
import cv2
from datetime import datetime
from tqdm import tqdmdef resize_image(image_path, target_size):"""Resize the image to the target size."""image = cv2.imread(image_path)resized_image = cv2.resize(image, (target_size, target_size))return resized_imagedef process_images_in_directory(directory, target_size):"""Resize all images in the specified directory to the target size and save them in the output directory."""timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")output_directory = os.path.join(os.getcwd(), f"resized_{target_size}x{target_size}_{timestamp}")if not os.path.exists(output_directory):os.makedirs(output_directory)image_files = [f for f in os.listdir(directory) if f.lower().endswith(('.png', '.jpg', '.jpeg', '.bmp', '.tiff'))]total_images = len(image_files)print(f"Processing images from directory: {directory}")print(f"Total images to process: {total_images}")for idx, filename in enumerate(tqdm(image_files, desc="Resizing images", unit="image")):image_path = os.path.join(directory, filename)resized_image = resize_image(image_path, target_size)# Save the resized imageresized_image_path = os.path.join(output_directory, filename)cv2.imwrite(resized_image_path, resized_image)print(f"Resized images are saved in {output_directory}")if __name__ == "__main__":if len(sys.argv) != 2:print("Usage: python resize_images.py <target_size>")sys.exit(1)try:target_size = int(sys.argv[1])except ValueError:print("Target size must be an integer.")sys.exit(1)# Get the directory of images, which is in the current directory under 'img'current_directory = os.getcwd()image_directory = os.path.join(current_directory, 'img')if not os.path.exists(image_directory):print(f"Image directory {image_directory} does not exist.")sys.exit(1)process_images_in_directory(image_directory, target_size)

三、转换脚本（.bat）

如果用python原代码运行

@echo off
python .\__pycache__\resize_images.py 512 %*
pause

如果用编译出来的.pyc文件运行

python -m compileall resize_images.py

@echo off
python .\__pycache__\resize_images.pyc 512 %*
pause
