ABSTRACT:
A method of creating a series of font characters (101) on a computer system (150) is disclosed. A series of font outlines (111) and source artwork (112); a series of manipulation tools (116) for the manipulation of aspects of the outlines and artwork. Such an arrangement provides for the creation of substantially arbitrarily complex font structures from the outlines, artwork and manipulation tools. A series of font characters is then formed through the application of the complex font structures to each of a base font outline in the series of font characters. Preferably, the complex font structures can comprise a graphical expression tree of operations (120) to be performed in the creation of a font and the tree includes an outline of a font character. The manipulation tools can include tools for distorting, replacing or compositing the outline of a font and can further include the tools for the application of morphological and non-morphological effects to the font outlines. A data structure for such font creation is also disclosed which includes records (90-97) of attributes of glyphs used to form the outlines including their shape, color, opacity and where appropriate compositing or blending with graphic object or pixel-based images.
