[Openexr-devel] Reading Only Specified Channels

[Jeff Higgins]

I'm just starting to get into openexr and I have a question about what 
the current version supports.

If I have an exr image that has say 12 channels and I only need to read 
3 of them (not necessarily RGB) does the reader support only reading the 
3 channels that I'm interested or do I need to read the entire file just 
to get the 3 channels that I'm interested in.

My inclination is that is very much possible. If so is there example 
code that I can use as reference.
