METHOD AND SYSTEM FOR FILE CONVERSION

摘要

A method for file conversion includes obtaining an original file including content, that includes objects. The method further includes rendering each object of the multiple objects into a page description language (PDL) format to obtain rendered objects, and extracting, from the original file, a tag for an object of the multiple objects. The method further includes generating object composition metadata based on a composition rule corresponding to the tag. The object composition metadata includes a description of a composition of the object in the original file, and is added with the rendered objects to a PDL file.

1. A method for file conversion from an original file to a page description language (PDL) file, comprising:
obtaining the original file comprising a plurality of objects comprising a graphics object delimited by a tag, wherein the tag in the original file specifies a type of the graphics object and a formatting attribute of the graphics object; translating the graphics object into an image object based on the type and formatting attribute in the tag; generating object composition metadata for the graphics object based on a composition rule corresponding to the tag that delimits the graphics object in the original file, wherein the object composition metadata comprises a description of the graphics object in the original file; adding the image object to a visible layer of the PDL file and the object composition metadata for the graphics object to an invisible layer of the PDL file, wherein the image object in the visible layer and the description in the invisible layer overlap, wherein the object composition metadata is searchable in the PDL file but is not visible when the PDL file is displayed, and wherein the PDL file does not have the tag.
