[Openexr-devel] OpenEXR version compatibility

[Piotr Stanczyk]

Hi All,

We have recently been having more and more problems with reading 
OpenExr files that have been generated with application linked against 
1.0.5 and processing these files with applications linked against 
1.2.1.
In particular, this is characterised by apparent pixel noise in the 
bottom of the image and, so far, only occurs when used in conjunction 
with the piz compression scheme.  Sometimes there are no errors 
reported when reading these file, at other times messages relating to 
the Huffman encoding crop up.
Am I correct in thinking that I should be safe in doing this? there is 
a file version attribute but it has not changed  across these versions.

Anyone had similar experiences of this?

Many thanks

Piotr

BTW  I managed to grab some some example images in the middle of our 
pipeline that demonstrate this quite well.
