    "log"
    "github.com/kelvins/imgproc"
)

img, err := imgproc.LoadImage("./face.png")
if err != nil {
    log.Fatal(err)
}

grayscaleImage := imgproc.ToGrayscale(img)

err = imgproc.SaveImage(grayscaleImage, "./face.png")
if err != nil {
    log.Fatal(err)
}

if imgproc.IsGrayscale(grayscaleImage) {
    fmt.Println("It is a grayscale image")
} else {
    fmt.Println("It is not a grayscale image")
}

imageSlice := imgproc.ConvertImageToSlice(grayscaleImage)

resizedImage, err = imgproc.ResizeImage(grayscaleImage, 100, 100)
if err != nil {
    log.Fatal(err)
}
