Mark,
It turns out to work perfectly well under 5.5. However this is on Lion.
And Lion was apparently very unhappy. For convert for example, I had to
specify the path to convert (using Andre Garcia's trick of 'which
convert' to get the path) AND the explicit path to the output file. In

I am curious about using ImageMagick on OSX with LC. I want to be able
to envoke IM and do simple stuff like a text dump of RGB values.
On windows this seems to work with Shell. But I am having a difficult
time on OSX.

Folks,
This is aimed at people who know the vagaries of the headless cgi mode
of old.
I am trying to set an image in a headless stack and then get its
imagedata. In other words, setting it to "http://blurf.com/myremote.jpg";
It does not appear to be working. Is this because the stack had no
Anyone using Lion and a 5.x version of livecode? I am on a pretty plain
vanilla system with nothing in particular added. Livecode crashes on any
attempt to print a script. If you are going to test this out (please
contact support if it works) make sure you save your stack and scripts
first.

I have to cobble something together which is not normally my thing, a
video app that doesn't do a bunch. What it does need to do though is
detect when there has been a significant change in frame.
I would need to be able to threshold this for significance, so I would

Phil,
Your final version of the script ended up winning the speed race. See my
note to Ken.
Thanks to everyone for pitching in. That was fun. Forced me to learn a
bit about baseConvert and binaryEncode/Decode

Hey Ken,
Oddly your terse script ran a bit longer than the "final" one the group
cobbled together by community heavy lifting. Not by much though. 1000
repeats on both showed yours was about 13 to 20 ticks slower.
Not at all what I would have expected either.

Okay, this is the final version of the script which does seem
considerably faster than where I started.
Thanks to all. Hope this was a useful walk-through.
Any other suggestions on ways to improve?

Jim,
Thanks so much. I wonder how much faster that is? And Guglielmo, I
appreciate you taking a crack at this. I don't get how to do the encode
using your approach at all since I am not familiar with the params for
the BinaryEncode function.

JB,
Well it gives some peculiar results because I clearly don't know much
about the encoding process in terms of passing the right params.
I rewrote this to be more general. Give it a try if you like and let me
know. It will handle carriage returns and such properly.
Seems speedy enough for

This appears to work for my purposes and is pretty speedy. See anything
that might break?

I have seen a number of sites that use a text to binary digits converter
for simple encryption. Such that "this is my text" would be written as

Thanks to everyone who tossed in their thoughts and code samples.
Francois, yes, it is a variation I suppose of wavelets, or a filtered
wave. It makes perfect sense. The degree of variation is something that
needs to be added as a function param so that significance can be
selectable on a perce
This is probably a bit less about livecode than it is about the Twitter
API, but perhaps someone has done this already.
I want to do some fairly deep searches into the Twitter archive. To do
that requires being able to dance around the "search since" restriction

would seem to me there just has to be an easier way to do it.

Jonathan,
Sure, that approach can work. But it isn't terribly efficient. It would
however be less computationally intensive if I detrend first. That's the
first step. So if you have a notion on a least squares linear fit line,
that would be most welcome.

Jerry,
Yes, that would be far too many hits and there has to be some scaling
applied as a filter for that reason. The criteria more precisely is
"significant" peak and trough values. With significant being the trick.
For example, is the peak or trough 3 percent or more away.

I had thought to use a sin function on the time series to find peak and
trough values. I would filter the sin function results for those close
to 1 or -1, though I am not sure what the filter interval will be just yet.
Then, I would be able to grab the value from the actual ti

No, these are data files in .csv format. Column data with high and low

I have a very large number of graphs to crunch through to find local
minima and maxima. The data is regularly spaced, which eliminated one
problem. I know too that the window value used has to be an adjustable
variable as peak and trough significance may need to be found for a wide
