<P>PROBLEM TO BE SOLVED: To solve the problem that when a filter pipeline system performs format conversion including attached files in a composite structured document file, each filter has input and output limited, so achievement by only one filter like a conventional pipeline system is not realistic since processing in the filter becomes complex, and to solve the problem that although a composite filter obtained connecting single-function filters can be prepared, achievement is not realistic either since the numbers of types and combinations of attached files in the composite structured document file are very large. <P>SOLUTION: An input document file in a first format is analyzed and when an analysis result indicates that a document file in a second format is attached to the input document file in the first format, a filter which converts the attached document file in the second format into a document file in the first format and a filter which combines the document file converted to the first format from the second format with the document file in the first format are set. <P>COPYRIGHT: (C)2012,JPO&INPIT |
