I want to list the foreground pixels between two specified pixels, and list them, in a connected component.

What do you mean "Connected component"?

n = max(x2-x1,y2-y1);
n = abs(n)+1;        % number of pixels between coordinates
indy = linspace(y1,y2,n);
indx = linspace(x1,x2,n);
indy = round(indy);        % indices of pixels you wnat
indx = round(indx);
