hello all,

i have some tiff files which were created by scanning under WinNT and written by windows imaging. i totally use Linux and do not have access to a Windows system. i am not able to open the tiff file under Linux in any image viewer. i have downloaded the latest version of lib tiff and tiff2png. the output i get from that is appended below.

can some one help me to convert this to normal tiff or any other readable format.


PS: i have send this mail once two days ago, but i did not receive a copy and also did not see any response. i have also searched the archives. so i am reposting this again, if you are getting this for second time kindly accept my apologies.
