python小脚本系列——png逐帧转jpg

本脚本完全由CHATGPT生成，我只是用文字描述了下需求，不满意的地方也是直接文字提出，修改了两次就完成了，效率YYDS！

import os
from PIL import Image

def convert_gif_to_jpg(gif_filename, output_folder, width=None, height=None):
    current_directory = os.getcwd()  # 获取当前工作目录
    gif_path = os.path.join(current_directory, gif_filename)  # 将当前工作目录和 GIF 文件名拼接起来

    with Image.open(gif_path) as im:
        frame_count = 0
        while True:
            try:
                im.seek(frame_count)
            except EOFError:
                break

            frame_count += 1
            if width is not None and height is not None:
                resized_im = im.resize((width, height))
            else:
                resized_im = im
            
            # 将调色板模式的图像转换为 RGB 或 RGBA 模式
            if resized_im.mode == 'P':
                resized_im = resized_im.convert('RGBA')
            
            # 保存为 JPEG 格式
            file_name = f"frame_{frame_count}.jpg"
            resized_im.convert('RGB').save(file_name, 'JPEG')

if __name__ == '__main__':
    gif_filename = "1.gif"
    output_folder = "output"
    width = 320
    height = 170
    convert_gif_to_jpg(gif_filename, output_folder, width, height)
