METHOD AND APPARATUS FOR DISPLAYING ENHANCED DOT MATRIX CHARACTERS Abstract A method and apparatus for displaying enhanced dot matrix characters is disclosed. Using stored sets of binary data elements which define the shape of the respective characters of a set, logical operations are performed to add additional binary data elements to provide the desired character. Characters are enhanced by either thickening the linear components thereof in a direction orthogonal to that of the linear components, or making them more dense by adding dots along the length of the linear components, or both. The store data defines the character with a high density in the horizontal direction and a lower density in the vertical and diagonal directions. The characters are enhanced by defining a reference matrix which comprises a subset of the stored binary data elements, adding blank binary data elements to the defined reference matrix at locations between the stored binary data elements, and comparing portions of the reference matrix including the added blank binary data elements with corresponding portions of a predetermined matrix, and converting to a dot those added binary data elements that match the elements of the predetermined matrix. Characters may be enhanced in one manner but not another, and they may be enhnaced along one or more linear components but less than all of them. CT9-85-010
