Method for creating and drawing reflowable layout files based on hierarchical index

Abstract

The invention relates to a format reflowable file establishing and drawing method based on hierarchical index. The unified annotation technology is provided, geometric structures of format files are described through recording of a surrounding frame of reflowable words, text line or text column parameters, an area surrounding frame and the like, and meanwhile one index number is given to each described geometric structure. For describing logical structures contained in the format files of sentences, paragraphs, sections, chapters and the like, one index number is given to each logical structure. The logical structures of the format files and reading priorities of the structures are described through the index numbers of the geometric structures or the index numbers of the logical structures. A hierarchical index structure shown by markup languages of an extensive markup language (XML), a standard generalized markup language (SGML) and the like is achieved. Files of various formats can perform annotation on format digital books through the method, and recording capacity is reduced. Through analysis of logical structures of the format digital books, format digital books of various formats can be read by using the same read program.

Description

technical field [0001] The invention relates to a computer file information structure technology, in particular to a method for establishing and drawing a reflowable file with a format based on a hierarchical index. Background technique [0002] At present, many digital books exist in layout file format or image file format, such as PDF, TIFF, PNG and CEB, etc. This type of e-book is mainly suitable for large-screen reading and print / print reading applications. However, formatted digital books are not suitable for reading and using on terminals or media with different screen or window sizes. For example, in order to read an A4-format digital book on a small-screen terminal, due to the lack of a reflow function for text rows / columns, it is necessary to reduce the page to the screen size to represent a complete row / column. But when a large-format book shrinks to screen size, the text is too small to read. Or it is necessary to continuously scroll the digital book page accor...

Problems solved by technology

The disadvantage of this method is that since images of many words or words are directly embedded in files such as HTML and XHTML, not only does it take a lot of storage space to save many sub-images, but it will also be affected when reading on the Internet.

[0009] 2. Patent document 2: Chinese patent, application number: 201210299088.2 An index-based format reflowable file creation and drawing method, mainly for single-page format files, proposed a method of using indexes to annotate text bounding boxes or line drawing bounding boxes, etc. , but for multi-page format files, such as patent documents or novel books, etc. often contain multi-page format files, Patent Document 2 does not provide a solution for multi-page format books
