Abstract

The invention relates to a method and system to realize the transformation of document format by virtual printing, and belongs to the document format transformation technology.In conformity to the descriptive principles of the printer language generated in the virtual printing process of the original document, the invention can combine the complicated background patterns, laces, wordarts and other complicated webpage element data into objects that can be described in less descriptive speech according to certain method and then the combined data of the printer language description can be transformed into target document format.By using the invention, the amount of descriptive language occupied by webpage graphics primitives are reduced in the target format document, and thus achieve the effect of faster target document production, smaller target document size and faster display of the target document in the corresponding reading viewers.The method and system adopted in the invention can produce document with the same visual effect of the original document in a fast and exact manner. It can also satisfy the requirement for possibly smaller size and faster speed of electronic document and hand-hold reading equipments.

Description

technical field

[0001] The invention belongs to the technical field of document format conversion, and in particular relates to a method and system for realizing document format conversion through virtual printing. Background technique

[0002] The conversion between document formats is generally completed by printing with a virtual printer. During the printing process, a temporary format file described by the computer printing language will be generated first, and then the target format file will be generated by parsing the file described by the printer language. If the converted electronic document contains page objects such as background patterns, charts, or WordArt, the printer description language document generated by virtual printing may decompose the background, chart, or WordArt page objects into a large number of small images , small path to describe, if the target format document is described by the small image and small path described in the printer language, the...

Examples

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] A system for realizing document format conversion through virtual printing, including the following modules:

[0038] (1) Reading module: used to generate an intermediate file described by the printer language from the original format document read by the virtual printer;

[0039] (2) Merge module: used to merge complex page element data described in the printer language;

[0040] (3) Conversion module: used to convert the intermediate file described in the printer language into the target format document.

[0041] The following submodules are also provided in the merge module:

[0042] 1) A sub-module for merging data describing "page primitive objects with the same width and height and the same content data";

[0043] 2) It is used to merge the data sub-modules describing "page primitive objects of equal width and adjacent up and down";

[0044] 3) It is u...
