So i tried my code snippet and it worked. The above thread asks you to
convert to greyscale and then do a pixel check.
For a sufficiently big picture(given most of the pictures today are >2-5MB,
this is expensive operation.
My code snippet, essentially iterates through the pixels in one go and based
on the threshhold of each of the RGB values, suitably converts it to B or W.
