Abstract
There is provided an method for a character-outputting apparatus which is capable of storing a character image defined by a character font, as bitmap data in the form of a dot matrix, and printing or displaying the character image. The bitmap data is converted temporarily to vector data when the character image is enlarged. Then a new line is drawn from a starting point of each vector of the vector data to an ending point of the vector in a vector direction, where is included a diagonal discontinuity between dots diagonally adjacent to each other, and an inside of the new line is filled to thereby regenerate bitmap data corresponding to the character image.
