Dithernator

Dithernator is a C++ program designed to apply a dithering effect to images. Dithering is a technique used in digital graphics to create the illusion of color depth and smooth gradients by using patterns of contrasting pixels. This program lets you process images and apply a dithering effect, generating a new output file with the prefix "Dithered_".

Purpose

This program was created for a friend who enjoys experimenting with image processing and visual effects. It was a fun project to bring a classic image manipulation effect into action with C++ and external libraries like stb_image for loading and saving images.

Features

• Dithering Effect: Applies a dithering effect to a given image, enhancing the perceived color range and visual appeal.
• Image Output: Saves the processed image with the prefix Dithered_ in the same directory as the input image.
• Cross-Platform: It works both on Linux and Windows.

How It Works

1. Input: The program reads an input image file .jpg .jpeg .png .bmp.
2. Dithering Process: It applies a dithering algorithm (based on pixel error diffusion) to the image to simulate a higher color depth.
3. Output: The processed image is saved with the prefix Dithered_ followed by the original image filename, resulting in a new file in the same directory.

For example, if the input image is named image.jpg, the output will be saved as Dithered_image.jpg.
