How to get the pixels

[goker]

Hello I have an image, I converted it to RGB via color to RGB function. now I need the access the pixels at least want to put them into an array so that I can work on the channels individually. I connected one channel to build array function.  then I connected it to an indicator. to see the pixels in that channel. Is that right way to do? afterwards I need to display that channel.
