Python Bulk Watermark Removal Guide

One way to remove watermarks from images in bulk is by using Python’s image processing library.

1. Firstly, you need to install the PIL (Python Imaging Library) library. You can install it using pip.

pip install pillow

1. Import relevant modules from the PIL library.

from PIL import Image
from PIL import ImageDraw

1. Create a function to remove watermarks. The function will take two parameters: the input image file path and the output image file path.

def remove_watermark(input_path, output_path):
    # 打开输入图片
    image = Image.open(input_path)
    
    # 创建一个与输入图片大小相同的空白图像
    watermark_removed = Image.new('RGBA', image.size)
    
    # 使用ImageDraw模块的Draw方法在空白图像上绘制输入图片
    watermark_removed.paste(image, (0, 0))
    
    # 保存去除水印后的图片
    watermark_removed.save(output_path)

1. Create a loop to process multiple image files. Assume all the image files are stored in one folder.

import os

# 指定包含图片文件的文件夹路径
folder_path = 'path/to/folder'

# 遍历文件夹中的所有文件
for filename in os.listdir(folder_path):
    # 检查文件是否为图片文件
    if filename.endswith('.jpg') or filename.endswith('.png'):
        # 构建输入和输出文件的路径
        input_path = os.path.join(folder_path, filename)
        output_path = os.path.join(folder_path, 'no_watermark_' + filename)
        
        # 应用去除水印函数
        remove_watermark(input_path, output_path)

By doing so, you can use the code above to remove watermarks from multiple images in bulk. Remember to replace ‘path/to/folder’ with the actual path to the folder containing your image files. Additionally, you may need to adjust the watermark removal method based on the circumstances.
