I have multi-page tiff files. I need to extract individual frames from the
multi-page tiffs and save them as single-page tiffs. 95% of the time I
receive multi-page tiffs containing 1 or more black and white CCITT4
compressed files (frames) inside the tiff. Every now and then I receive a
mixture of black and white CCITT4 and JPEG compressed files, and sometimes
just multi-page tiffs with JPEG only. The code runs great when dealing with

BLOB field in a database, save it to file, then convert the pages
within TIFF file into jpegs (using GDI+) and display on the web (using
ASP.NET).
However, when I generate the Image object using FromStream (passing in
