Abstract

The invention discloses a PDF file processing method and system, and the method comprises the steps: obtaining the number of pages of a to-be-previewed PDF file, and creating a canvas container according to the number of pages of the to-be-previewed PDF file, wherein the number of the canvas containers is consistent with the page number of the to-be-previewed PDF file; rendering the canvas containers through predefined elements, associating the to-be-previewed PDF file to the rendered canvas containers, reading the to-be-previewed PDF file in the canvas containers, and loading the to-be-previewed PDF file to a preset page. According to the scheme, the canvas containers are created according to the page number of the to-be-previewed PDF file, the number of the canvas containers is consistent with the page number of the to-be-previewed PDF file, so that the canvas containers can store the to-be-previewed PDF file, and the to-be-previewed PDF file is loaded and displayed through the HTML5 framework; while the cross-screen compatibility is achieved, the output of the PDF file can be kept, so the user can preview the content of the PDF file, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of file processing, and more specifically, to a PDF file processing method and system. Background technique [0002] Portable Document Format (PDF) is a portable document file format developed by Adobe Systems for file exchange in a manner independent of applications, operating systems, and hardware. PDF files are based on the PostScript language image model. [0003] During the project development process, when multiple pages of PDFs are displayed to users with business logic, because the underlying frameworks of each APP embedded in the project are different, resulting in a blank phenomenon when the PDF files of individual native frameworks are displayed, causing users Cannot preview the contents of the PDF file. [0004] Therefore, the existing method for previewing PDF results in poor user experience. Contents of the invention [0005] In view of this, the present application discloses a PDF...
