Abstract: An information-processing device (such as an image-processing device) executes a boldface character generating process when it is judged that a character should be expressed in boldface type based on a drawing instruction inputted from outside and there exists no boldface form data of the character corresponding to font information comprised in the drawing instruction. In the boldface character-generating process, the information-processing device generates pattern data lacking at least one dot at each of the four corners and generates the boldface form data by enlarging the drawing area of bitmap data (generated from standard form data) based on the pattern data. The at least one missing dot at each of the four corners of the pattern data, allows edges of the generated boldface character to be expressed finely even when the boldface character is generated from a character having an oblique element (oblique line, curved line, etc.).
