Scanner color pixel

i am trying to write a color scaner from a photo. I set the BALL to move all over the canvas.

Currently, getpixel background recognizes from position x-0, on every y line.
How to do a peek at every x position, on every line y.

Try this-

it works in one line (
needs more time to test), canvas width is 360 and height is 480,
I am trying to speed up, but something is wrong. HELP !!!

my solution.
1.Set the timeinterval very low, i.e. min 1
2. add more Ball - more is faster
Now, my canvas 360x480 make 25 s. it ok
without Alpha2020, I would still have sleepless nights. Thank you
