Abstract
Abstract There are provided a character processing method and apparatus having a function to convert data such as a character or the like which has been encoded by a vector form, into data of a dot form. The apparatus has a converter to convert data of a vector form into data of a dot form, and a discriminating circuit to discriminate whether painting of an outline is omitted or not, on the basis of the size of output data after conversion into dot-form data. As the result of the discrimination, if the painting process should not be omitted, the painting process is executed. If the painting process can be omitted, the painting process is omitted. Even a large character can be processed at a high speed without deterioration in the quality, and a small character can be processed at a high speed at a high quality.
