Arbitrary precise orientation specification for layout of text

A novel method for the layout of text strings over some given free-form parametric base curves is considered. Each letter of the string is represented by a collection of cubic and linear Bezier curves. The layout of the string over the free-form parametric curve is derived as a symbolic composition of the string geometry (i.e. a sequence of Bezier curves) and a free-form parametric surface S(u, v) with the parameters u, v between zero and one, and S(u, 0) given by the base curve. This method has proven to provide great flexibility and give high quality results in layout of text.
