A method and apparatus for constructing, storing and displaying characters
Abstract
A method and apparatus for creating and storing characters for display on a video screen. The shape of the graphic character is displayed at various degrees of resolution. The graphic character is stored as a bitmap or as coefficients of spline curves (1-20). These can be scaled up or down to give different character sizes. The coefficients can be converted to form pixelmaps which are rectangular arrays of pixels. The pixelmaps may have gray scale values.
