No, no no.  Using the equation: 2^n (my own little equation :)  )to find
out how many vertices are in an nth dimensional "square" you get:

0- 1 vertex - a pixel
1 - 2 verts- a line segment
2 - 4 verts- a square
3 - 8 verts- a cube
4 - 16 verts- a hypercube
5 - 32 verts- a fifth dimensional "cube"
etc
etc
etc

So.....a pixel is a 1D object, not a line (don't get into the fact that a
pixel is actually a square! I am considering to be a single point).
