This runs in the Acrobat app - there is no separate API for this task.
Setting 'Printing Allowed: None' completely stops anyone from printing the document. Choosing 'Low (150 dpi)' allows printing, but only at a low quality. This means the printed document will not look sharp or professional, which can be useful for sharing drafts where you don't want high-quality copies made.
Adobe Acrobat requires an owner password to ensure that only the document's creator or authorized person can alter its security settings. This prevents unauthorized users from removing printing, editing, or copying restrictions, thereby maintaining the document's integrity and intellectual property protection.
If you enable 'Changes Allowed: Form Fill', recipients can only fill out forms within the PDF. They cannot insert new pages, delete existing pages, rotate pages, or extract content. This setting is perfect for surveys or applications where you need input but want to keep the document's structure and content unchanged.
'Restrict Permissions' is an Adobe Acrobat feature that lets you control what others can do with your PDF document, such as printing, editing, or copying content. It is important for document sharing because it helps protect your intellectual property, maintain confidentiality, and ensure that your documents are used exactly as you intend, preventing unauthorized modifications or distribution.
