Took me a while, mainly because I was also testing image processing libraries, but I have implemented a basic argument system. Currently there is only height and width, as well as verifying filepath for the source image, which is always first. They can have 2 flags, normal and alternate, and can have an integer attached or not, and can be put in any order after the filepath. Next thing to do is take the input image, resize and loop through all pixels, calculating brightness.
