Abstract

The invention discloses a method and device for processing paths in a PDF file, and relates to the technical field of information. According to the method and device, wiping can be accurately performed on the paths in a designated area of the PDF file, and the effect of erasing the paths in the designated area of the PDF file can be improved. The method includes the steps of obtaining the paths inthe PDF file; classifying the paths; performing erasing processing on the paths according to the designated area by using preset erasing processing rules corresponding to the types of the paths, wherein different types of paths correspond to different preset erasing processing rules respectively; converting the paths subjected to erasing processing into sub-items constituting the paths; on the basis of the sub-items, regenerating new paths in the PDF file. The method and device are suitable for processing paths in PDF files.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and device for processing paths in PDF files. Background technique [0002] Portable Document Format (PDF), a file format developed by Adobe Systems for file exchange in 1993. The advantage of this format file is that it is cross-platform, can retain the original format (Layout) of the file, and is an open standard. This feature makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. More and more e-books, product descriptions, company announcements, network materials, and e-mails are beginning to use PDF format files. [0003] In practical applications, in order to protect the user's confidential information, the user sometimes needs to erase the data in the specified area of ​​the PDF file. According to the type of elements that need to be erased, there are several types such as tex...
