Installation

Prerequisites

• Windows operating system
• Python 3.11 or higher
• Required Python packages (see requirements.txt)

Installing Dependencies

pip install -r requirements.txt

Building the Executable

To obtain the ".exe" file, you can download the latest release from the GitHub repository or build it yourself using the provided build script.

To build yourself a standalone executable use a build.py script:

1. Ensure all required assets are present:

   • assets/images/atorus_logo.png
   • assets/images/pdf_utility_logo.png
   • assets/images/python_logo.png
   • assets/images/pdf.ico

2. Run the build script:

   python build.py

The script will:

• Verify all required assets exist
• Clean previous build directories
• Create a new executable using PyInstaller
• Package all necessary resources into the executable

Feel free to customize the build script to include additional assets or modify the build process.

Usage

   • Full processing with TOC and bookmarks

Operating Modes

Simple Combination

• Select source folder containing PDFs/RTFs
• Choose output filename
• Optionally set password protection
• Click "GO!" to combine files

Full Processing with TOC

1. Select source folder containing RTFs/PDFs
2. Provide metadata CSV file (use existing or create/save new using the template button)
3. Configure TOC options:
   • Select font for TOC
   • Set title separator
   • Choose bookmark options
4. Set output filename
5. Click "GO!" to process files

Metadata File Format

The metadata CSV file should contain the following columns:

• TLF: Type of document (L/F)
• Title3: Main title
• Title4: Subtitle
• Title5: Population/group
• ProgName: Program name
• Seq: Sequence number
• OutputName: Output filename
• Order: Sort order

Example:

TLF,Title3,Title4,Title5,ProgName,Seq,OutputName,Order
F,Figure 14.1-5.3,Spaghetti Plot,Safety Population,g_120_dose,1,F_14.1-5.3,1
