Python Script for Capturing VitalSource Book Pages

This Python script automates the process of capturing screenshots of pages in VitalSource Bookshelf applications (.vbk) and compiles them into a single PDF file. It uses pyautogui for GUI automation and Pillow for image handling.

Prerequisites

Before running the script, ensure you have Python installed on your system along with the following packages:

• pyautogui

• Pillow

Install these packages using pip:

pip install pyautogui pillow

Configuration

You need to configure the coordinates for the page capture area and the "Next Page" button based on your screen setup and the VitalSource Bookshelf application's layout.

Capture Area Coordinates

Set the coordinates for the area of the screen where the page content is displayed:

• Top-left corner: (90, 86)

• Width and Height: 1500 x 888

Adjust these values in the script to match the area of the page you want to capture.

Alternatively, if you want to capture the entire screen without specifying coordinates:

• Full Screen Capture: Replace the capture_page function's content with image = pyautogui.screenshot(). This will capture the entire screen instead of a specific area.

Next Page Button Coordinates

Set the coordinates for the "Next Page" button:

• X and Y: 1643, 1015

Ensure these coordinates point to the "Next Page" button in your application.

Usage

1. Open the VitalSource Bookshelf application and navigate to the first page of the book you want to capture.

2. Run the script:

python app.py

4. Enter the total number of pages when prompted. The script will capture each page and compile them into a PDF named output.pdf.

Script Breakdown

capture_page()

Captures a predefined area of the screen and converts it to an RGB image. Adjust the coordinates and dimensions to match the page layout of your book.

go_to_next_page()

Simulates a mouse click on the "Next Page" button. Set the coordinates to match the location of the "Next Page" button in your application.

main()

The main function handles the capturing of all pages and saving them into a PDF. It manages page transitions and ensures that all pages are captured before creating the PDF.

Troubleshooting

Incorrect Coordinates: If the screenshots do not capture the correct area, adjust the x, y, width, and height values in the capture_page() function.

Timing Issues: If the script pages too quickly or too slowly, adjust the sleep times in the main() function.
