Hi forum~,

I'm a newbie with puredata/gem.

I have a [pix_video] input from the webcam and I want to read some color information of the source. First of all I want to know the brightness of the input image. Further it would be interesting to have values for red, green and blue.

Is it possible that gem is nearly undocumented? I can not find any "help" explaining what inputs and outputs of the objects are. neither in the internet neither with the classic pd help function.

thank you!
Michael

sorry for disturbing. there are a lot of threads treating this issue. I just want to post the solucion for other newbies that find this useless thread:

information you can get with pix_data or pix_pix2sig~
further Information about GEM-Objects you can find at Help -> Browser -> DOC/5.reference/GEM/
