  • Method and system for controlling the conversion of a file from an input format to an output format
    Patent number: 6195664
    Abstract: A system and method for controlling the conversion of a file from an input format to an output format is provided. The method includes a computer-implemented method for controlling the conversion of a computer file from an input format to an output format by determining the best path for converting the file from the input format to the output format using family objects. The method includes the steps of receiving the input format and the output format, and generating a node in memory for each family object that can read the input format. The method further includes the step of generating successful branches of nodes in memory that include one or more nodes such that each successful branch includes a first node that can read the input format and a last node that can write the output format. Finally, the method includes calculating a best path through the successful branches of nodes.
