Actually, they are in normal resolution. In fine resolution the image 
would have been approximately right. This is an image viewer issue, and 
has nothing to do with Asterisk or spandsp. A lot of image viewers get 
the aspect ratio of FAX images wrong, and many will only display the 
first page. The default FAX viewer installed with a fresh installation 
of Windows is very usable, but people insist on replacing it with 
something worse. Hence, this problem is quite common. See
