PDF Watermarking Tool Usage Guide

Introduction

This guide will walk you through the process of using the PDF Watermarking Tool. This tool allows you to add watermarks to all PDF files in a specified directory, using names from a text file.

Prerequisites

Before you begin, make sure you have the following:

• Node.js installed on your computer.
• The necessary directory structure and files prepared.

Installation

1. Install Node.js: If you haven't installed Node.js yet, download and install it from nodejs.org.

2. Install the PDF Watermarking Tool: Open your terminal and run the following command to install the tool globally:

   npm install -g add-pdf-watermark

Directory Structure

Ensure your directory structure is set up as follows:

.
├── fonts
│   └── SimSun.ttf
├── pdfs
│   ├── document1.pdf
│   ├── document2.pdf
│   └── ...
├── names.txt

• fonts/SimSun.ttf: Contains the SimSun font file.
• pdfs/: Directory containing the PDF files you want to watermark.
• names.txt: File containing the names to be used as watermarks, each on a new line.

Usage

1. Prepare names.txt:

   • Open names.txt in a text editor.
   • Add the names you want to use as watermarks, each on a new line.

   Example:

   Alice
   Bob
   Charlie

2. Add PDF Files:

   • Place all the PDF files you want to watermark in the pdfs/ directory.

3. Run the Tool:

   • Open your terminal.
   • Navigate to the directory containing your names.txt and pdfs/ directory.

   • Run the following command:

     watermark

Output

After running the tool, you will find a new output/ directory in your current directory. This directory will contain subdirectories for each name, and within those subdirectories, the watermarked PDF files.

Example structure after processing:

.
├── output
│   ├── Alice
│   │   ├── document1_Alice.pdf
│   │   ├── document2_Alice.pdf
│   ├── Bob
│   │   ├── document1_Bob.pdf
│   │   ├── document2_Bob.pdf
│   ├── Charlie
│   │   ├── document1_Charlie.pdf
│   │   ├── document2_Charlie.pdf

Troubleshooting

If you encounter any errors during the process, ensure the following:

• The fonts/SimSun.ttf file is correctly placed.
• The pdfs/ directory contains valid PDF files.
• The names.txt file is correctly formatted with one name per line.

For further assistance, refer to the error messages in the terminal to identify the issue.
