[REBOL] Image-Lab Function Implementation
From: robbo1mark::aol::com at: 3-Mar-2001 5:09
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
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.)
image/lab/preview/bmp %ukiah.jpg %ukiah.bmp 'invert
whilst this is a trivial change, what about the proper behaviour of certain
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,
