To run: use stack build.
After the program has been built, you can execute the program with
stack exec inverBMP-exe <image.bmp>
where <image.bmp> is the 24 bpp bmp image of your choice. blackbuck.bmp is provided as an example to demonstrate.
stack build
stack exec invertBMP-exe blackbuck.bmp
Then check your current directory: you should see an inverted black buck!
