Follow-up Comment #1, patch #9712 (project octave):

How does bwpack handle images that are more than 2 dimensions? Does the result
differ in big-endian and little-endian machines differ?

I think the code be made simpler by using bitpack. Something like this:


bitpack (BWP(:), 'uint32')


which may also make it faster since it removes the for loop.

You don't need to check if image islogical. Just cast it as logical and be
done.

I remember once writing this function but never finished because I found some 
with bitpack. I don't remember what but I still have a unfinished patch where
I'm rewriting bitpack in core :/

I thought this function was only really useful with imerode and imdilate have
support for packed images which they don't.
