Use javascript to make Submission PDF compliant with main PDF eCTD Specifications

This includes some of the following checks plus many more

1. PDF Version: It checks if the PDF version is higher than 1.7.

2. Metadata: It ensures that the PDF has the essential metadata:

   • Title

   • Author

   • Subject

   • Keywords

3. Security: Verifies if the PDF is encrypted or password-protected.

4. Page Size & Orientation: Ensures every page is A4 size and checks its orientation.

5. Embedded Fonts: Checks if all fonts used in the PDF are embedded within it.

6. Bookmarks & Bookmark Panel Status:

   • If bookmarks are present, the bookmarks panel should be open.

   • If bookmarks are absent, the bookmarks panel should be closed.

7. Document Size: Checks if the document size exceeds a specified limit (in this script, 100MB).

8. Thumbnails: Ensures thumbnails are present.

9. Non-standard Annotations: Warns about any annotations found that aren't Text, Link, or FreeText types.

10. Rotation: Verifies if any page has been rotated from its original position.

11. Hyperlinks: Checks for the presence of external hyperlinks, especially those leading to the web (http: or https: links).

Note: This list is derived from the script you provided earlier. It offers a broad overview, but it's worth noting that, depending on the specific eCTD guidelines and regional differences, additional checks might be necessary.
