Structure processing method and system of layout file

Abstract

A representation method, system and device are disclosed, relating to the information representation method and system in the computer information process technique. The invention is to solve the prior layout file's problems of being not flexible and not easy to add or modify. By obtaining the logical structure information and content reference sequence of a layout file; dividing said content reference sequence into multiple content reference sub-sequences according to said logical structure information, and creating content dividing description file; creating logical unit description file according to said logical structure information; associating said content dividing description file to logical unit description file, it is effective and flexible to represent the logical structure information of layout file, and there is no need to modify the original layout file and any content in the layout file can be separately described in logical structure information, extracted and reused in different document logical structure modules.

Description

technical field [0001] The invention relates to a method and a system for expressing structural information of computer electronic documents, in particular to a method and system for expressing structural information of format files. Background technique [0002] Format file technology is to convert the original format of files in various formats into a unified format. During the conversion, the format and information such as text, charts, formulas, and colors in the original file are truly maintained, and it can be read on different terminal devices and The software has the consistency of the displayed results. The layout file adopts an absolute description method. In the custom coordinate system, the displayed position and size of each graphic element (such as characters, pictures, tables, etc.) are clearly recorded, so that the printed results of the document and The result of browsing on the computer is consistent, and it has display consistency under any computer envir...

AI Technical Summary

Problems solved by technology

There are various defects in this method in practical application: first, modifying, adding, and deleting document logical structure information all require modifying the content instruction stream of the layout file, which is a complex and error-prone modification process

Secondly, the granularity of instruction flow division (a granularity can be considered as a logical unit) is limited. The minimum granularity is the entire content of a certain output instruction. There may be situations where a certain content segment cannot be further divided.

[0007] In view of the current large number of layout files that do not contain document logical structure information, the application requires adding document logical structure information to these layout files, and the layout files that contain document logical structure information are inflexible in the processing of logical structure information, and it is not easy to add and modify Layout files cannot meet the needs of users. Designing a document structure processing method in Layout files is of great value for the practical application of Layout files.
