ABSTRACT:
A system and method of producing a bold character from a base character which has been transformed in orientation, size, or both, the method comprising overstriking the transformed character non-orthogonally, asymmetrically, or both, to produce the bold character. A preferred embodiment for overstriking the transformed character non-orthogonally, asymmetrically, or both, includes overstriking the transformed character relative to the CTM. Further, overstriking the transformed character relative to the CTM preferably includes (a) determining a multistrike quantity representative of a number of offset overstrikes, (b) determining a horizontal vector and a vertical vector, relative to the fixed reference point, based on the multistrike quantity, (c) transforming the horizontal vector into a transformed horizontal vector and the vertical vector into a transformed vertical vector, using the CTM, and (d) overstriking the transformed character at points along the transformed horizontal vector and transformed vertical vector to produce the bold character.
