Document loading method and device

Abstract

The invention relates to the technical field of information display, and specifically discloses a document loading method and device. The document loading method comprises that an Open XPS original document is divided into three kinds of document blocks, the document blocks comprise an application-required document block, an image resource document block and a content carrier document block, the byte stream of the application-required document block is obtained first, the byte stream of the image resource document block is obtained in parallel at the same time, after the byte stream of the application-required document block is obtained, a virtual document is packaged, the virtual document obtains the byte stream of the content carrier document block in the page from a remote server according to the page required by a client, the virtual document can obtain the byte streams of the completed three document blocks and can directly position the byte streams, and the packaged virtual document is provided to the client as a complete document. According to the invention, the documents are provided to a reader in order in a manner that document blocks are separated in types and are obtained in parallel, the document loading time is shortened, and the user reading experience is improved.

Description

technical field [0001] The present invention relates to the technical field of information display, in particular to a method and device for document loading based on splitting and revirtualization. Background technique [0002] At present, online readers convert original documents in various formats, such as Word, PowerPoint, Excel, Txt, into some kind of intermediate documents, and realize online reading in most formats by supporting the reading of intermediate documents. [0003] There are generally several principles for the selection of intermediate documents. One is that other original documents can be converted into intermediate documents more conveniently and quickly; The application of the reader is more extensive, and the intermediate document is required to facilitate Internet transmission and support cross-platform. Usually choose the Open XML Paper Specification (Open XPS) format document. [0004] The Open XPS file format is an international standard, the sta...

Problems solved by technology

[0006] In the process of realizing the above-mentioned document loading process, the prior art has the following problems: 1. The Open XPS document needs to be completely acquired before it can be displayed. When the document is larger, the time from the initial acquisition to the final presentation will be longer, and The memory usage will also be larger, so that the user will have to wait too long before they can read, which will affect the user's reading experience; 2. Sometimes the user may only need to read part of the document, by simply ordering the document size The method of splitting, downloading in parallel, and finally recombining can speed up document acquisition, but the document must be restored to a complete compressed file before it can be used. It does not achieve on-demand acquisition, which fundamentally improves the reading experience. not obvious

[0007] At present, there is no effective solution to solve the above problems
