As a background art, Korean Patent Registration No. 0751010 (August 22, 2007) discloses a method of generating a PD document by merging and editing documents from various application programs. The original document from the office document, Hangul, Hunminjeongeum, image document, CAD document, and other electronic documents), i.e., homogeneous or heterogeneous, can be changed and merged and edited without damaging the original. It is a technology that can generate PDF documents by only one conversion process from the contents.

This is to provide a method of generating a PDF document having a viewer function that allows the client system to preview the contents of a plurality of original documents without a corresponding application or a dedicated viewer of the original document on the server.

The above-described technique provides a preview function and an editing function for inserting, deleting, reordering, copying, moving, pasting, etc. pages of a PDF to be generated using a meta file.

As described above, the background technology merely converts an original file into a PDF, and provides only simple editing, and does not provide a function for processing a user and inputting it in the PDF. It could not solve the problem of low efficiency because it was utilized only to the extent that it can be seen through paper.
