LC and ImageMagick from OSX

[Bryan McCormick]

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.

Also, presuming I get it to work b4 someone gets back to me, how do I 
get results back from the shell? For example calling convert 
someImage.png someImage.txt in the shell gets an RGB dump written to a 
file. Is there any way to have that text come back to LC? Or is it best 
just to read from the file created by the command and not worry about 
data exchange?

Thanks
