Problems solved by technology

This is both an advantage of this method and, on the other hand, a disadvantage
Because the application does not do any other operations, it can only generate a simple PDF file, which can only include basic text, images, tables and other data, and further content, such as from table of contents / footnotes / endnotes to the text , cross-reference links within / between files, hyperlinks to the Internet, etc., are not possible

Embodiment Construction

[0016] First, the intermediate file EMF file involved in the present invention is introduced. The EMF format is a standard file format provided by the Windows operating system, and its full name is EnhancedMeta File, referred to as EMF. By calling the relevant function interface (API) of the operating system, the application program can easily and quickly generate the EMF file. The EMF format was developed on the basis of the earlier WMF format. WMF is the abbreviation of Windows Meta File. After enhancing its functions, the EMF format was formed. In the following, only the EMF format will be described, but the content, method and device described above are also applicable to the WMF format.

[0017] From the application point of view, EMF is an image file format like JPG, GIF and other formats. Various commonly used word processing / image processing / browsing software all support this format, and can view, browse and even edit EMF images. . The fundamental difference betwee...

Abstract

The present invention relates to the field of computer application technology, in particular, it relates to a device and its method for making file type conversion in computer. In the concrete, it is a device for generating PDF file. Said device includes EMF file generation module and converter from EMF file to PDF file. Said converter includes EMF file processing module, EMF file recording ergodic module, conversion module from EMF file to PDF format and PDF file processing module. Besides, said PDF file processing module provides a function interface for application program, so that said application program can add other data into PDF file.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a device and method for converting file types in a computer. Background technique [0002] PDF is the name of a file format invented by Adobe Corporation of the United States, and its full name is Portable Document Format, referred to as PDF. [0003] Computers have penetrated into all aspects of our work and life, and one of the important areas is daily office work, typically including word processing, spreadsheet applications and electronic presentation applications. All kinds of data edited and processed by users are finally saved in the form of files for further editing, mutual exchange, archiving, and so on. Usually, applications use the file format defined by the developer to save data. For word processing software, "what you see is what you get" has become a necessary standard function, that is, the user's output on the printer is the same as his own. The effect seen...
