Abstract
PURPOSE: To slightly reduce the line width of a character to obtain a neat form of the character by preliminarily setting values for line width reduction of the character in a table at the time of rounding processing and using these boundary values to perform omission or raising processing. CONSTITUTION: The direction attribute of a point in the middle of processing is obtained, and coordinate data of the point is multiplied by 48/256. When rounding processing of a decimal fraction of the operation result is next performed, the processing is performed based on a table corresponding to the detected direction attribute. That is, when the direction attribute of the point in the middle of processing is, for example, '1', fractions of 0.9 and over are rounded up as 1 and the rest is cut away with respect to the X coordinate after reduction, and fractions of 0.2 and over are rounded up as 1 and the rest is cut away with respect to the Y coordinate after reduction. This boundary value table for raising and omission is so set that the character width is slightly reduced. By this constitution, the character width is slightly reduced to obtain a neat form of a character.
