Screen Grab

Important notes

FPDF2 is required in order to create a pdf with the correct dimensions. To remove the older version if present run : pip uninstall fpdf To install the new version pip install fpdf2

Required libraries

• FPDF2
• pyautogui
• tkinter

Testing functionality

Please carry out the following to check the main functionality of the code.

• The app needs to be able to capture a user selected area of the screen.
• It needs to process all images into a pdf
• Navigate here and use auto mode to capture the 3 pages and combine in to a pdf.
• The above is easier in Edge full screen mode F11, zoom in / out to fit the page to the screen.

Intended Purpose

To grab a user defined area of the screen repeatedly and save images for later processing. This has been expanded to create a pdf from the captured images.

Why Do I Need This

Documentation on some websites is not accessible for my needs and in some cases not possible to download in an accessible format or at all! I also prefer a record or point in time copy of materials in a format suitable for offline use in the future.

Why Not Use Snip

It is possible to use snip but I need to extract documents with hundreds of pages, snip is too slow and I need more control over the captured area and repeatability. This application now also saves the files as a multi-page pdf.

OCR ?

I have looked at doing this and the current conclusion is that it is too complex to add to this project. The generated pdf can be OCR'd using the following : ocrmypdf It is not a casual installation but it is very quick once it is working especially on a multi-core machine.

Compatibility

• Windows, works and is the primary development platform.

• Linux / Ubuntu, testing in progress. Currently working with some small issues. sudo apt install python3-pip pip install pyautogui sudo apt-get install python3-tk python3-dev pip install fpdf2

• Mac, developers / testers needed.
