RE: [Openexr-user] Questions for more experienced users

[Luc-Eric Rousseau]

Although I know this is off-topic, I understand 
what John Coldrick is saying.. however as an 
application development who's had to deal with Tiff, 
the only real basic interop is the LZW patent,
and some companies like Mental Images who (while
selling software for thousans of dollars) refused to 
support it.  Personally I've had interop problems 
everytime we upgraded our OpenEXR version. It's just goes
along with adding new features.  Recently, apps have 
needed a libtiff upgrade for the new floating point 
compression scheme, however prior to that it hadn't 
changed in 10 years.

That LZW patent has expired, by the way.
