ABSTRACT:
A dot-matrix data producing apparatus including a first device for transforming, according to scale data indicative of a scale of an output character within a first range of scale values, original outline data including original width data indicative of an original width of a reference stroke of an original character, into transformed outline data including first transformed width data indicative of a first transformed width of the reference stroke, according to a first relationship between transformed width values and scale values wherein the transformed width values increase as the scale values increase; a second device for transforming, according to the scale data indicative of the output-character scale within a second range smaller than the first range, the original outline data into transformed outline data including second transformed width data indicative of a second transformed width of the reference stroke, according to a second relationship between one or more transformed width values and the second-range scale values wherein each of the one or more transformed width values corresponds to the scale values within a corresponding one of one or more sub-ranges of scale values within the second range of scale values; and a third device for producing dot-matrix data from the transformed outline data including the first or second transformed width data.
