Image-Lab Function Implementation

Jeff, Image-Lab function in it's current incarnation does not have the appropriate behaviour in all instances. For example consider the effects block [rotate 90] Whilst the effect works perfectly, you will see that there is a problem with the face/size, the face/size/x and face/size/y values should be swapped here so that the full image appears rotated on it's side. Is this easily fixed within the current implementation design of passing 'effects as parameters in a block? (maybe the 'effects arguments should also have a word! option.) for example image/lab/preview/bmp %ukiah.jpg %ukiah.bmp 'invert whilst this is a trivial change, what about the proper behaviour of certain effects? This is only the first anomaly I've discovered, without doing a full test of all effects options we don't know if there might be more. Maybe Implementing effects as refinements may offer the fine grained control needed to ensure proper behaviour. I hope not, because I like your design of effects being a block! (or word!), much smaller and cleaner. Your thoughts please, Mark Dickson
