Hi Krishnamurthy,

For what its worth,

I got this code from a Sun community website (http://today.java.net/pub/a/today/2004/04/22/images.html)
that allows one to generate images from unicode text.

I have modified it to generate wbmp images using the Sampige font.

Please note that for wbmp output, you will need the JAI Image I/O API from
here - http://java.sun.com/products/java-media/jai/

For png and jpeg output you do not need the above package, just JDK 1.4 will do.
