Click OK to confirm your settings and close the dialog.
Click OK again in the Document Properties window.

This runs in the Acrobat app - there is no separate API for this task.
The 'Low (150 dpi)' setting means printed copies will have lower image quality, making them less clear. 'High' allows for the best possible print quality. You might choose 'Low' if you want to allow printing but discourage high-quality reproductions of your document.
An owner password is required to ensure that only authorized individuals can alter the security settings of a PDF. This prevents unauthorized users from removing restrictions you've set, such as preventing printing or editing. It acts as a key to unlock and change the document's protection features, maintaining the integrity and security of your information.
When you restrict changes Allowed, it governs actions like inserting, deleting, rotating pages, and page extraction. However, the ability to fill out forms is a separate action. If you want to allow form filling but prevent other edits, you need to ensure 'Form fill' is permitted while other 'Changes Allowed' options are restricted.
'Restrict Permissions' means you are setting specific rules on what others can do with your PDF. This includes controlling if they can print it, make changes to its content, or copy parts of it. It helps you protect your document's information.
