Abstract: There is provided a picture-forming device which is capable of easily drawing an arrow having a desired shape on a display screen of a display device, such as a CRT. The picture-forming device is capable of setting a basic shape of an arrow to be used in picture-forming. The basic shape of the arrow set is stored. When arrow display conditions indicative of a position, a direction, and a length of the arrow are entered via the display screen, data of the basic shape of the arrow and data of the arrow display conditions are synthesized, to display an image data thus synthesized, on the display screen.

Abstract: Picture plane data of a picture plane file is converted to picture plane data of a GIF file format on a frame unit basis by a picture plane data forming module. A list display picture plane in which a plurality of miniature picture planes are arranged is formed from scenario data and the image data of all frames by a list display picture plane forming module. Further, on the basis of the scenario data of a scenario file, a frame converting module forms scenario data of an HTML file format for switching to each frame picture plane by the selection of the miniature picture plane in the list display picture plane and the switching among the frame picture planes.
