When you edit a document — for example, by rotating all pages — PSPDFKit Document Engine saves a new asset for that document and updates all relevant annotations.
-
Your service requests that the Document Engine rotates all pages of the document. PSPDFKit Document Engine retrieves the document from the asset storage for processing.
-
PSPDFKit Document Engine transforms the document, rotating all of its pages.
-
PSPDFKit Document Engine persists the transformed document in the asset storage without deleting the original. It returns the new document’s properties to your service.
