Hello Everyone:

Here is a small trivial problem from a newcomer. I would really appreciate any help with regards to it.

this is what I want to do: I have a tiff file.. What I was trying to open & read this file and write the contents of it to another file. The sample code which I have written down is given below. I would like to know whether it can be done or not and if yes, where am I going wrong in the code...

thanks in advance...

Regards,
