StegBit hides by finding the nearest value that has the selected bit set to match the message. So if the bit being used for hiding is #$3($value $=8),$ the message bit is a one, and the pixel value is $7,$ then we add one to change the pixel value to $8.$ If the pixel value were $179(0$xB$3==10110011)$ we could add $8$ or subtract $4.$ Since subtracting $4$ yields the closer value $(175$ is closer to $179$ than $187),$ that is what we do to get $175(0$xAF $==10101111).$ Calculate the max capacity in bytes of the cover file Simpsons$\_24.$bmp a $24$ bit image with dimensions $1024$ x $576$
