This runs in the Acrobat app - there is no separate API for this task.
Comments are usually text-based notes, like sticky notes or text boxes, that you add to explain something or ask a question. Markups are visual changes to the document, such as highlighting text, underlining words, or drawing shapes. Both help with reviewing documents, but comments add new text, while markups draw attention to existing content.
It is important because comments and markups are saved as a separate layer on top of your document. If you do not flatten or sanitize them, others can still see your review notes, which might contain private information or old feedback. Flattening makes them a permanent part of the document, while sanitizing removes them completely. This prevents accidental sharing of sensitive information or review history.
You can add comments to specific images by using a text box or a callout tool. First, select the 'Comment' tools. Then, choose the 'text box' or 'callout' tool. Click near the image you want to comment on, and type your note. This lets you link your feedback directly to the visual content.
