A data processing apparatus serving as a display device receives at a user instruction processing portion (107) a designation of electronic data (101) to be displayed and responsively reads through an input portion (103) sub block data (102) prepared for the electronic data (101). Of the read sub block data (102), each block's start/end locations, and a location of an area to be displayed on a screen, as seen from the file's top, are referred to to read only a required block. Then the electronic data (101) hierarchical structure is analyzed and a layout calculation portion (106) calculates a layout provided within a screen for display, and a display unit (108) displays the electronic data (101). <IMAGE> |
