Hi,
	After neglecting a little TIFF app I wrote for the Mac about 
9 years ago, I decided to use it as an exercise in porting to OS X. 
Right now Apple's Preview app that comes with OS X doesn't show other 
than the first page of multi page TIFFs, so I'm hoping to get my app 
up to the task and it could fill a useful niche, if only for viewing 
faxes. Right now my app only supports single page PackBits 
compression of 1 bit TIFFs.
	After getting my app over to OS X, I started trying to open 
some multi page TIFF files I have. I couldn't open them, even the 
first page, because they don't use PackBits compression (compression 
= 32773). These TIFFs have a compression type of 3 listed in their 
files (tag 259). Looking at the TIFF 6.0 spec from 1992, there are 
only 3 types of compression listed, types 1, 2 and 32773. Am I 
missing something here? I can't find any newer "offical TIFF" docs 
that talk about any other compression schemes. Apple's Preview app 
and other apps I have can open the first or last page of these TIFFs, 
so I must be missing something...
	Also, I was not able to log into the 
ftp.onshore.com/pub/libtiff as anonymous. It said anonymous was OK, 
but when I put in my email as a password, it said access denied.

Any and all help would be greatly appreciated.

Dave
