Abstract
In enlarging dot matrix data stored in an original memory on a work memory, it is discriminated whether or not a data write position overlaps the position of already-produced data. If no overlapping occurs, the data is written as it is in the work memory. If overlapping occurs, it is then discriminated whether or not the color of a dot in the original memory to be processed is the same as that of a dot adjacent to the target dot. If the colors are the same, data is written at positions except the overlapped portion. In other words, data already written at the overlapped position is given a priority. On the other hand, if the dots are of different colors, data at the overlapped portion is temporarily cleared and data is written at positions including the overlapped portion.
