Python 获取修改文件名和图片加水印logo

获取文件夹内的所有文件

import os

def get_file_list():
    dir_path = r'C:\Users\h290602\Desktop\Project 4789826211'  # 待读取文件的文件夹绝对地址
    files = os.listdir(dir_path)  # 获得文件夹中所有文件的名称列表
    file_list = []                # 存放路径中的文件内容
    for file in files:
        new_path = os.path.join(dir_path,file)
        if os.path.isdir(new_path): #判断是否是文件夹
            for file in os.listdir(new_path):
                file_list.append(file)
        else:
            file_list.append(file)
    return file_list

get_file_list()

修改文件夹内所有图片名称

import os
folder_path = r'C:\Users\h290602\Desktop\pictures'
files = os.listdir(folder_path)
os.chdir(folder_path)
for i,old_name in enumerate(files):
    new_name = f'霍家户外苏州东山徒步_{i+1}.jpg'
    os.rename(old_name, new_name)

给图片添加logo

from PIL import Image

logo_path = r'C:\Users\h290602\Desktop\HON logo.png'  #logo文件位置
subject = '霍家户外04月徒步活动'  
save_folder = r'C:\Users\h290602\Desktop\霍家户外04月东山徒步活动'  #新文件保存目录

imgs_folder_path = r'C:\Users\h290602\Desktop\霍家户外活动\04月东山徒步'
files = os.listdir(imgs_folder_path)
os.chdir(imgs_folder_path)
for i,file_name in enumerate(files):
    new_file_name = f'{subject}_{i+1}.jpg'
    img = Image.open(file_name) # 背景图像
    img = img.convert('RGB')  ##防止报错  ‘Cannot write mode RGBA as JPEG’
    # logo图像
    logo = Image.open(logo_path)
    # logo的大小进行调整
    scale = 0.5
    logo.thumbnail((int(logo.width * scale), int(logo.height * scale)), Image.ANTIALIAS) #resample=Image.ANTIALIAS是指定了放大缩小按照最高质量进行
    r,g,b,a = logo.split()
    # logo位置
    logo_x = img.width - logo.width - 10
    logo_y = img.height - logo.height - 10
    img.paste(logo,(logo_x,logo_y),mask = a)
    # 保存
    img.save(os.path.join(save_folder,new_file_name),quality=100)
