The Library of Babel function below enumerates every black-and-white bitmap k-pixels high of increasing width as you move up the y-axis.

mod([floor(floor(y/k)/2^(k*floor(x)+mod([floor(y),k]))),2])>1/2,x>0,y>0

Change k below to vertically enumerate all black-and-white bitmaps k-pixels high.
When k = 1, you it is a graph of the integer 0, 1, 2, .... stacked vertically, and represented in binary notation with the least significant bit on the left next to the y-axis.

k=1

The two functions below put a frame around each bitmap.

mod([y,k])=0,0<x<floor(1/k*log(floor(y/k),2))+1

x=floor(1/k*log(floor(y/k),2))+1,y>k
