‌Python中批量给图片添加图片水印(第7节)


Python编程对比其它编程语言而言,主要的特点就是易学易用、跨平台、多功能。在上一节教程中,已经介绍了如何利用Python的Pillow库和Tkinter库轻松实现批量添加文字水印的功能。在本节教程中,将介绍如何使用Pillow库和Tkinter库批量给图片添加图片水印。

批量给图片添加图片水印的效果图如下所示:

1、批量给图片添加图片水印过程分析

我们的主要目标是批量为某个文件夹下的所有图片添加水印。首先,准备一张合适的水印图片(比如一个透明背景的logo图片),建议使用png支持透明通道的格式。同时,准备好需要添加水印的一批图片,将它们放在一个文件夹中,方便批量处理。

程序通过Python的PIL(Pillow)库和Tkinter图形用户界面(GUI)创建一个应用,用户可以通过简单的界面选择需要批量添加水印的文件夹和已准备好的水印图片,选择水印位置、透明度、水印缩放比例和水印角度,处理后的图片还能保存到指定的文件夹中。点击“批量添加水印”按钮后,程序会自动为指定文件夹中的所有图片添加图片水印,并保存到指定文件夹中。

在选择水印图片和调整水印参数过程中,左侧的预览区域会尝试打开指定文件夹内的第一个图像文件,显示出添加水印后的预览图片。

具体实现步骤如下:

  • 首先,使用os.walk()方法遍历指定文件夹中的所有文件,筛选出图片文件(根据文件扩展名判断)。

  • 使用Image.open()方法分别打开待处理图片和水印图片。

  • 获取水印图片的尺寸、水印位置、透明度、缩放比例和角度,再使用paste()方法将水印图片粘贴到原图片上。

  • 选择输出文件的路径,最后使用save()方法保存处理后的图片。

  • 调用add_watermark_process()函数对每个图片进行水印添加操作。

2、代码实现

(1)安装Pillow库

首先,确保你已经安装了Pillow库。如果还没有安装,可以通过pip安装:

pip install pillow

(2) 导入必要的库

import os
import tkinter as tk
from tkinter import filedialog, messagebox, ttk
from PIL import Image, ImageTk
import time
import glob

(3)图片水印制作核心代码

# 图片水印制作函数
def add_watermark(open_image, watermark_path, output_folder_path, position, opacity, watermark_scale_percent):
    try:
        # 获取原始图片文件名(包含扩展名)
        open_image_name = os.path.basename(open_image)
        file_name, file_extension = os.path.splitext(open_image_name)

        # 水印完成后,创建输出文件名,在原始文件名后添加_时间戳后缀
        # 获取当前时间的时间元组
        current_time = time.localtime()
        # 将时间元组格式化为字符串,例如,将时间“2025年08月23日09时22分30秒”格式化为“20250823092230”
        time_str = time.strftime("%Y%m%d%H%M%S", current_time)
        output_image_name = file_name + "_" + time_str + file_extension

        my_watermark = Image.new('RGBA', blank_image_dims, (255, 255, 255, 0))

        watermark_position = (int(my_watermark.width/2), int(my_watermark.height/2))
        my_watermark.paste(resized_watermark, watermark_position)
