float c = ((img.pixels[(x+y*img.width)] >> 8) & 0xFF)/255.0;

can you tell me what this code is doing - I know it is extracting G value of RGB and then is it diving by 255 to get hex value?

Thanks!

Hi.
Where did you get that code?
It really gets the float value of the green segment.
But dividing it with 255 makes no sense to me.

I think I’ve got it Noel - I think it’s to constrain the value between 0 & 1.
