How can I get any information from gem-window ?

as we all know ,  a  Gem-window generally used to be a output Object that shows what is rendering in our patch,  and here's my questions:

is there any Gem functions or Geos  or gem-properties  that can send out the detail infromation in gemwin  ? (like make a gem-window being a input method )

for example , a certain position(x,y) 's color message ?

actually, here I wanna to do is that 1st I send my webcam or a normal pix_video to gemwin , and 2nd, I want read a certain position color , and send it out to print (I dont know if we must send it to gemwin and after that I could scrab the message, or we could directly get the certain messages ?)

Hi andm,

I have the same question - did you ever find a way to do this?

[gemlist_info]   will give you the transformation matrix in floats.....  does that help?

[pix_data] will give you color info on a particular pixel, or area.

Thanks Nestor, pix_data looks like it'll do exactly what I want.

On a similar note: Do I have to render the picture to a gem_win, or is it enough to have a gem_start and a pix_video?

You do not need to display the video to use either of the abovementioned objects..
