ABSTRACT:
A font generation apparatus comprises a memory in which font data, which represents a matrix of dots or the outline of a font, is stored. The logic states of the stored bits are converted so that a bit pattern created by the converted bits represents a reflection of the bit pattern of the originally stored font data with respect to a line which equally divides the matrix, and the logic states of the bits stored in the memory are further converted so that a bit pattern created by the further conversion represents a rotation of the reflected bit pattern by 90 degrees.
