Data conversion method and computer program

Abstract

A technique is provided to accurately and efficiently convert hierarchically structured vector data with multiple layers of graphic elements into mesh data. The data conversion method performs the following steps: S2 to S4, extracting repeating patterns used in multiple locations within the input data as fragments; step S5, determining whether the graphic data constituting the fragments overlaps with other structural graphic data; and, if step S5 determines there is no overlap, further performing: step S7, generating fragment data belonging to the mesh data of the fragments and other structural data belonging to the mesh data of other structures; and step S8, using the fragment data and other structural data to generate output data. This improves conversion efficiency by separating repeating patterns from other structures during mesh data conversion and prevents areas that should be non-depicted from becoming depicted areas, thus enabling accurate and efficient conversion into mesh data.
