Abstract
Advancement in digital-image processing hardware has given the
printing industry novel facilities for capturing fonts and has provided
new grounds for character scaling, which is an important issue in
typesetting and graphical text. An algorithm for digital character
scaling by a contour method is developed and implemented. The algorithm
is based on scaling the contour of the character through a
transformation. Cubic splines are used to interpolate the discrete
samples of the contour character. Final results show no jaggies. The
algorithm is applied to Arabic fonts and compared to two other
algorithms: replication and telescoping template. The superior
performance of the contour method is attributed to the cubic spline
fitting, which gives better smoothness to the edge of the
character
