You can use multiple annotation types in one session, such as highlighting text and adding sticky notes for detailed feedback.
This runs in the Acrobat app - there is no separate API for this task.
Highlighting text in Adobe Acrobat uses a color to mark specific words or sentences, making them stand out. It's good for drawing attention to existing text. A text box, however, lets you add new text anywhere on the page, separate from the original content. This is useful for longer notes or explanations that don't fit directly into the existing document text. Both are forms of annotation but serve different purposes in how they interact with the document's content.
You should sanitize a PDF document before sharing it to protect privacy and prevent information leaks. Comments and markups are stored as a separate layer, meaning they can still be seen or recovered even if they appear hidden. Sanitizing removes all review notes and hidden data, ensuring that only the final, intended content is visible. This is especially important for sensitive documents where review notes might contain private discussions or unfinished thoughts.
A 'comment layer' in Adobe Acrobat is like a transparent sheet placed over your main document. All your sticky notes, highlights, and other markups are added to this layer, not directly to the original text. This matters because it means your comments are separate data. If you don't 'flatten' or 'sanitize' the document, this layer can still be accessed, even if it seems like the comments are gone. This is important for ensuring privacy and control over what information is shared in your final document.
