ABSTRACT:
In a character generating method and apparatus for producing a bit map image of a designated character size from outline data, a character developing circuit calculates a shearing factor of a target stroke when a conversion scaling factor is smaller than a predetermined scaling factor, performs shearing compensation on coordinates of individual points of the target stroke along a coordinate axis according to a type of the target stroke, based on the shearing factor, and converts outline coordinate data obtained through the shearing compensation, to physical coordinates, for the designated size based on the conversion scaling factor. A drawing circuit produces a bit map image of the designated character size from the converted physical coordinates. The character generating apparatus further has a font memory for storing the outline data. The character developing circuit calculates the shearing factor of the target stroke, read from the font memory from coordinates of two predetermined points of a stroke expressed by the outline data.
