ABSTRACT:
A character processing apparatus includes a reading circuit to read out data stored in a vector form; a first converter for multiplying an enlargement/reduction ratio to the readout data and converting the resultant data; and a second converter for converting the converted data into the data in a dot form, and a circuit to extract the data converted by the first converter in accordance with an output area which can be output in a lump, wherein the extracted data is converted by the second converter. When an output request indicates the row direction, the vector data is converted into the dot data in row. When an output request indicates the column direction, the vector data is converted into the dot data in column. Thus, a character of a high quality can be efficiently output at a high speed. When the vector data is converted into the dot data, the painting process is properly selectively executed in the row or column direction. Thus, a character can be formed at a high speed.
