If you *want* your algorithm to be coupled to a particular source of data, then ranges will only get in your way. (Although it may be worth asking yourself: are you really sure that's what you want?)

AV data gets very large, and has complex processing that can be easily vectorized.

Formats like PNG, support compression via say zlib. So you're going to need to send a block of memory over to it.

Point is, using ranges for this is just shooting yourself in the foot if you want any type of performance that isn't bad.
