This project demonstrates how some basic accessibility checks could limit the number of online PDF files with blocking accessibility issues by displaying a warning in a form before the file is being uploaded. This demo does only three checks on PDF files:
- is the document tagged?
- is the document scanned?
- is the document protected against the use by assistance technologies?
Here is a screenshot of the demo :
This is a Python project. You need python 3 on your computer. To install the required libraries, please use the following command:
pip install -r requirements.txt
You can start the web server with the following command:
flask run -h localhost -p 8080
The demo is then available on http://localhost:8080. You can try uploading untagged PDF files or scanned PDF documents. A warning message should then be displayed.
