Thanks for the help....first i tried the method suggested by Mr. Ben
Tupper....but it dint work out (i tried it with dim(1) & dim (2) also
) ....it was just displaying a blank window.

Then i tried to work with TVIMAGE.pro & it is working fine. Yet
there is this problem of the window size...whatever be the true size
of the image, it is always displayed in a 512 x 512 window

Cheers
Gaurav
