For every pixel of this image: Subtract row mod 7 from the blue component of the pixel, where row is the row of the current pixel. Add col mod 9 to the red component of the pixel, col is the column of the current pixel. The green component should be unchanged. Make sure to check for overflow and underflow, since bytes are unable to store values below 0 or above 255. If you find overflow, set the byte to 255. If you find underflow, set the byte to 0. Create a new image that is the mirror-image of the image from the previous step. (The left side and the right side are reversed.)

Can someone please write the code as to how to do something like this?
