Technical Field

The invention relates to the field of file processing, in particular to a PDF file-based comment separation processing method and device.

Background

Currently, paperless office has become a necessary trend, and PDF has become an important delivery format for digital examination as the most common printing format. When an engineer processes a file in a PDF format, annotation information needs to be added to the PDF file, however, in the existing annotation adding manner, annotation content needs to be written into the PDF file, which actually changes the original PDF file, for example, the MD5 value of the original PDF file is changed, thereby reducing the reliability of the original PDF file.

Disclosure of Invention

The embodiment of the invention provides a method and a device for processing annotation information, which are used for at least solving the problem that in the related art, when annotations are added to a PDF (portable document format) file, the annotation content needs to be written into the PDF file, so that the reliability of the PDF file is reduced.

Optionally, the method further comprises: when the PDF file is transmitted, the PDF file and the target annotation are transmitted separately.

Optionally, the method further comprises: editing and modifying the annotation content in the annotation list, and synchronizing the edited and modified annotation content to the database.

According to another embodiment of the present invention, there is provided an apparatus for processing batch annotation information, including: the adding module is used for adding a target annotation at the target position of the PDF file; the storage module is configured to store the target annotation as an annotation file independent of the PDF file, where the annotation file includes annotation content of the target annotation, the target location, and a corresponding relationship between the PDF file and the target annotation; and the loading module is used for loading the annotation content on the corresponding position of the PDF file according to the annotation file when the PDF file is reopened.
