Representation method and system of layout file logical structure information

Abstract

The present invention discloses an expressing method and a system of layout file logical structure information, which relates to an information expressing method and a system of layout file in the computer information processing technology. The present invention obtains the layout file logical structure information and the content reference sequence; divides the content reference sequence into a plurality of content reference sub-sequences according to the logical structure information and generates the corresponding content division descriptive files; generates the descriptive file of a logical unit according to the logical structure information; divides the content into the descriptive file and the descriptive file of the logical unit for association; and performing file treatment to the layout file after treatment according to the association of the content division descriptive file and logic unit descriptive file. The present invention has the advantages that the method can effectively and flexibly express the layout file logical structure information, flexibly treat the layout file structure and meet user demand.

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 Format files cannot meet the needs of users. Designing a representation method for document logical structure information in format files is of great value for the practical application of format files
