Mr Thomas :
thank you so much for the explanation. Being totally new to batik, I was
not sure of how the system worked. I did go through the website and read
about all the features batik has to offer. I have also downloaded batik
and am getting to know more about it, so that i can use it in a class
project of mine.
I was not sure of what i was doing and your explanation clarifies a lot of
things that i had in mind. I did look up the slide show application and i
used the initialization code in my program. I am trying to make it work.
thanks again for your timely help,
I really appreciate it
Ananth
