Jamal,

Please see inline responses below.

FYI, the PDF you posted is not viewable in Adobe Reader 8.1.2. It does show the 
correct number of pages, but it displays no content.

The program you posted should not be expected to work on either Windows or 
Linux, as it is not a complete program, i.e., it throws 11 errors when I 
compile it on Windows. You are supposed to post a small, but complete, program 
that demonstrates/exhibits your problem.

Your input files work fine with my program, ScaleAndTile3, when I use it to 
convert your TIFF files to PDF files. The TIFF conversion in my program is 
similar to that of the Tiff2Pdf tool in the iText Toolbox.

You might try using the Tiff2Pdf tool in the Toolbox to see if it exhibits the 
same problems you have with Linux.

I see you're using methods from iText 2.1.0 and up that are replacements for 
(old) methods that were deprecated in the iText 2.0.7 that you used to generate 
your example PDF. Have you checked the iText JAR file for your Linux 
installation to see that you're using a compatible version, i.e., one that has 
the new methods?

If you'll post the 4-page TIFF file that's causing your problem, I'll be glad 
to run it through my program to see if it's compatible.

P.S. Just curious. Why are you using iText 2.0.7?
