Abstract:
In character design in the comput
er industry, the mathematical m
odels like Bézier curves and
B-Spline curves play a very important role. Earlier characters were stored in the bit maps, and
the designer had to keep separate file for each
size of each font. But after Adobe introduced
the PostScript fonts into the market, the font
s were represented by Bézier curves and those
fonts can be scalable to any size.
Further, this needs only one or
two files for storing the entire
font type.
Existing methods of representing characters an
d theoretical background
about Bézier curves
and B-Spline curves are reviewed in this study.
Further, we have developed a
Visual Basic program called “Fon
tica” for designing characters
by using Bezier and B-Spline curves. With the
help of this new program we could design 10
Sinhala (my mother language) characters.
In addition, we have proposed a new techniqu
e for approximating the degree reduction of
Bezier curves. This approximation appears to perform satisfactory.
