Abstract
Character pattern transforming system providing a character pattern whose size can be reduced or enlarged with an optional scale factor includes a gray scale device providing a plurality of values per pixel for adjusting the gray scale associated with the character pattern. The system further includes a pixel positioning circuit for determining the position of each pixel of the reduced or enlarged character pattern and a pixel coloring circuit for determining which of the pixels in the reduced or enlarged character pattern is to be colored based on the gray scale data. The thickness of the vertical lines of the transformed character pattern can be adjusted following enlargement or reduction of the character pattern. A detector circuit identifies right angle corners of the original character pattern to ensure that such right angle corners are maintained in the transformed character pattern.
