Abstract

There are provided an image-forming device and method for varying an elongation rate of a basic image in at least one of a direction of length of the basic image and a direction of width of the basic image based on a specific elongation pattern to thereby form a deformed image from the basic image, as well as a printing apparatus incorporating the image-forming device. Elongation data of the elongation pattern is stored. Basic image data representative of the basic image is developed into a dot matrix. Each dot line of the basic image data extending in at least one of directions corresponding respectively to the direction of length of the basic image and the direction of width of the basic image is duplicated based on the elongation data. A dot line generated by duplication of the each dot line is added between the each dot line and a following dot line adjacent to the each dot line.
