[PD] Converting colours to sound

Hi all,

Thanks for the great info.  [pix_mean_color] is awesome!  I was looking for
something like this for a patch.  My patch is very similar to the ones in
this thread, but I'm looking to have multiple synths generating sound using
different areas of the movie or picture.  I'd REALLY love if I could
specify a polygon, single pixel, or set of pixels (arbitrary or along a
ling segment or curve) within the picture, for [pix_mean_color] to use.

I've been searching through the gem objects for a way to limit which
pixels [pix_mean_color]
will see.  I imagine another possibility is to show limited areas of the
same video, each in a different patch, and then use [pix_mean_color] as in
patches above.   I'm not experience with gem and can't imagine how to do
either.  Has anyone done this?

Best,

Chris
