Re: [Openexr-devel] Storing multiple layers in OpenEXR files

[Florian Kainz]

For the next release, I can add a channelsWithPrefix() method
to class ChannelList.  We don't currently have a pre-defined
vector-of-strings attribute, but I can add that, too.

Does the proposed way of representing layers -- channels in
the same layer have a common prefix, ordering of layers is
described by a vector-of-strings attribute -- work for
everyone who is currently storing multiple layers in a
single OpenEXR file?

If you are using layers, what exactly does the "layer order"
attribute mean?  Is it the stacking order for compositing?
If this is the case, which order do you prefer, front-to-back
or back-to-front?
