5.13.6 Invert Filter code hs

Use Haskell's Ju-icyPixels library to invert image colors by subtracting each RGB value from 255, saving the new image.Code for an "Invert Filter" in Haskell (HS). An invert filter typically inverts the colors of an image, making each color its opposite on the color spectrum.In Haskell, this can be done by manipulating the color channels of an image. Haskell has several libraries for image processing, such as Ju-icyPixels, which can be used for this purpose.Here's a basic example using the Ju-icyPixels library to create an invert filter:1. First, you need to install the Ju-icyPixels package, which can be done using Cabal or Stack.2. Then, you can use the following code snippet as a starting point:```haskellimport Codec.PictureinvertColor :: PixelRGB8 -> PixelRGB8invertColor (PixelRGB8 r g b) = PixelRGB8 (255 - r) (255 - g) (255 - b)applyInvertFilter :: Image PixelRGB8 -> Image PixelRGB8applyInvertFilter = pixelMap invertColormain :: IO ()main = doRight img <- readImage "path_to_your_image.jp.g"case img ofImageRGB8 imgRGB8 -> writePn.g "output.pn.g" $ applyInvertFilter imgRGB8_ -> putStrLn "Unsupported image format"```This code will:Import the necessary functions from Ju-icyPixels.D.efine `invertColor` to invert the RGB values of a single pixel.D.efine `applyInvertFilter` to apply this inversion to every pixel in an image.In the `main` function, read an image, apply the invert filter, and save the result.Make sure to replace `"path_to_your_image.jp.g"` with the path to your input image, and `"output.pn.g"` with the desired output file path.This is a basic implementation. Depending on your requirements, you might need to handle different image formats or add error handling....
