Abstract

A method is described which combines characters from different-sized geometric text fonts into a single string and performs manipulations on the string CAD systems. This method removes the necessity for an application to individually place different-sized characters within a string to achieve accurate alignment and transformations. Geometric text is a means to describe the appearance of text that is placed on geometric objects on an all-points-addressable (APA) device. It differs from the normal raster text used on most non- graphics systems in that the character appearance is defined in the font as a series of line segments or "strokes." Raster text fonts contain a "pel-by-pel" description of the characters' appearance and, therefore, cannot be manipulated in an efficient manner.
