DRAWING DATA GENERATION PROGRAM, DRAWING DATA GENERATION DEVICE, AND DRAWING DATA GENERATION METHOD

摘要

A computer generates drawing data from display information of a content in accordance with an analysis result of a content hierarchical structure (Step 301), and stores the drawing data in a first drawing buffer out of a plurality of drawing buffers (Step 302). Then, in response to an update of the content, the computer specifies a non-update area and an update area out of the display information of the content on the basis of the analysis result (Step 303), and generates update drawing data from updated display information of the update area (Step 304). Further, the computer stores drawing data of the non-update area stored in the first drawing buffer and the update drawing data in a second drawing buffer out of the plurality of drawing buffers (Step 305).
