IPC: G09G5/20
Filed: 1986-03-20
Abstract: PURPOSE:To substantially shorten the time required for drawing a graphic and to improve the ability drawing a graphic by splitting graphic data to horizontal or vertical linear graphics and drawing graphic data in a picture memory at every linear graphic based on a parameter regulating the linear graphic. CONSTITUTION:Instead of considering a graphic to be a group of plotted dots and writing it in the picture memory for the unit of a picture element, a graphic is split to linear graphics where plotted dots continue in the horizontal or vertical direction, and written in the picture memory at every linear graphic, thereby realizing a quick graphic drawing. When graphic data specified by a graphic drawing instruction is drawn, first an MPU obtains a plotted dot address, judges whether the obtained address continues at an address previously obtained in the horizontal or vertical direction, and extracts components comprising the linear graphic. The parameter regulates the linear graphic extracted from the graphic data, and a graphic is drawn at every linear graphic. This process is repeated until all graphic drawing steps end.
