-Hi Sam,
-
-I noticed in the README from libtiff that you would like to know about
-what people have done with libtiff, so I thought I would drop you a
-line.
-
-We have used libtiff to create and convert TIFF images of financial
-documents which are sent from and to major document processing systems
-in Sweden and Denmark.
-
-I would like to express my deep gratitude to yourself and Sillicon
-Graphics for making this excellent library available for public use.
-There is obviously a lot of work that has gone in to libtiff and the
-quality of the code and documentation is an example to others.
-
-One thing that libtiff did not do was work on a memory area rather than
-files. In my applications I had already read a TIFF or other format
-file in to memory and did not want to waste I/O writing it out again
-for libtiff's benefit. I therefore constructed a set of functions to
-pass up to TIFFClientOpen to simulate a file in memory. I have attached
-my mfs (memory file system) source code for you to use or junk, as you
-see fit. :-)
-
-Once again, thanks very much for making my life simpler.
-
-Best Regards,
-
-Mike Johnson.
