ImageModding

A rudimentary Photoshop-like project that allows for the creation of layers, the importing and exporting of images, and the modification of those images through filters using low-level data transformation. (shrink, opacification, blur, sharpen, greyscale, etc).

• Uses industry standard Object Oriented Design principles including but not limited to the Model-Controller-View, Factory methods, Open Close Principle, and Adapters

model Design Overview

ImageClasses

• CustomCheckerBoard - A custom type of image that creates an image of a checkerboard based on the inputs.
• PPMImage - Initializes an Image from a PPM image, which is essentially a large file of RGB values.
• RainbowImage - A custom type of image that creates an image representing a rainbow using the standard colors one would expect.
• ImageUtil - A provided file that helps read in PPM files.
• AbstractImage - The abstract class that implements the methods of the image, extended in order to create more custom Images.
• Image - The interface that provides all of the methods to be implemented by AbstractImage, makes an Abstract image open to modifaction via the classes in the Modifications folder.

Modifications

• Blurry - A class that provides the kernal's values in the form of a matrix used to make an Image more blurry.
• Sharpen - A class that provides the kernal's values in the form of a matrix used to make an Image sharper.
• Sepia - A class that sets a matrix's values for adjusting a photo's RGB values to give it a sepia tone.
• Greyscale - A class that sets a matrix's values for adjusting a photo's RGB values to make it black and white (greyscaled).
• Filter - Uses the given kernal values to adjust an image
• Transform - Uses the given matrix to adjust the Color value of an image.
• IModifyImage - the interface that wrapps Filter and Transform, used to apply the filters to images.
• Mosaic - Applies a "stained-glass" affect to the image by generating seeds, mapping each pixel to the nearest seed, and then taking the average of each pixel mapped to the same seed. This is the only part of our program that we had to change. This class directly implements IModifyImage because it has its own, unique apply method. It works like an other modification such as sepia or sharpen.
• DownScale - Creates a new Image of the provided dimensions which is a smaller version of the provided Image. We only needed to add this one class. This class does not implement IModifyImage because the effect is changing the dimensions of hte image, but everything else in IModifyImage only changes the colors of the pixels.
