The major goal of this work has been the development and implementation of an interactive bit mapped font editor that enables the graphics programmer to create different fonts and icons for use in application programs. The font editor, called edit-font, has been implemented on the Silicon Graphics, Inc. IRIS workstation. Editfont consists of approximately 3500 lines of code, including the program documentation. Fonts created by editfont can be retrieved from disk and high level routines implemented with the IRIS graphics library. One feature of the system is the capacity for font extraction from a picture. The steps for font generation via font extraction are explained in detail. file formats, data structures and routines used by the system are also described. Software and hardware limitations of the system are outlined, as well as possible future extensions.
