if binaryEncode allowed using an array (like binaryDecode(C*), the
imagedata of img "myImg", outArray) instead of a predefined list of
variables, then it would be possible to use array multiplication to
extract and compare parts of an image e.g. multiply by [1,0,0,0] for
alpha, [0,1,0,0] for red, etc. But it is not possible and running the
loop to convert imageData to an array will be a major speed limitation
anyway.
Some time ago I filled up an enhancement request
http://quality.runrev.com/qacenter/show_bug.cgi?id=7636
. Or as said above a feasible alternative would be possibility to use
arrays or at least lists in binaryDecode.

It's these types of discussions that make this list so valuable, in
which all of us get a change to explore different algorithms and
learn a lot along the way.
I've been expecting Alex Tweedly to jump in with some clever use of
arrays for an order-of-magnitude speed increase, as he's done so many
times before. :)
:-)
I'm on holiday - otherwise I'd be trying to contribute something to
this interesting task.
Hmmm - now I need to find a way to use arrays ...
