<p>The present invention relates to apparatus, for displaying dot matrix characters, formed from selected binary data elements each representing either a dot or a blank, of the type which comprises storage means (16, 72) for storing sets of binary data elements, each set defining the shape of a respective character, logic means (73) for performing logical operations on each set of stored binary elements to generate associated additional binary data elements which can be used to enhance the rezpective character selectively, and display means (14, 75) for displaying each character using the associated stored binary data elements and associated additional binary data elements in order to display the character in an enhanced form (Figures 3, 7). Apparatus in accordance with the invention is characterised in that the display means uses the generated additional binary data elements together with the stored binary data elements to increase the density of at least one of the vertical, diagonal and horizontal linear components of the character being displayed along the linear direction thereof. According to a preferred embodiment of the invention the display means uses the generated additional binary data elements together with the stored binary data elements to increase the thickness of at least one of the vertical, diagonal and horizontal linear components of the character being displayed in a direction generally orthogonal to the linear direction thereof. The invention also relates to a method of displaying dot matrix characters in an enhanced form using apparatus as above.</p> |
