Hello, I'm still pretty new to programming, so I've come to ask for help.

I need to scale a grayscale image using C++, but I'm not sure where to start. I have the input of a grayscale image, one variable to scale the width of the image and a variable to scale the height of the image. If I can get pointed in the right directions or something, it will be greatly appreciated. I have attempted to search for answers, but I have not been successful.

Thanks for the help in advance.
