Hi,
I have put up the tiff file on the site:
http://www.cs.tamu.edu/people/neerajk/test.tiff
And here are the contents of logfile.txt:
[2002/01/22 18:36:29] log.c:35 0: Imager - log started (level =
1)
[2002/01/22 18:36:29] iolayer.c:972 1: io_new_fd(fd 4)
[2002/01/22 18:36:29] io.c:235 1: mymalloc(size 52) -> 0x82b8d38
[2002/01/22 18:36:29] iolayer.c:980 1: (0x82b8d38) <- io_new_fd
[2002/01/22 18:36:29] iolayer.c:829 1: io_glue_commit_types(ig
0x82b8d38)
[2002/01/22 18:36:29] iolayer.c:830 1: io_glue_commit_types: source
type 3 (CBSEEK)
[2002/01/22 18:36:29] io.c:235 1: mymalloc(size 8) -> 0x82b8a30
[2002/01/22 18:36:29] tiff.c:89 1: i_readtiff_wiol(ig 0x82b8d38,
length -1)

Thanks,
Neeraj.
