PPM Image Editor
Build an image editor from scratch in modern C++ that reads and writes the simple PPM format with zero external dependencies. You load pixels into memory, apply filters such as grayscale, blur, and flip, and save the result, all without any imaging library. A visual project that makes buffers and algorithms tangible.

What You'll Build
A command-line image editor that loads a PPM file, applies filters like grayscale, invert, box blur, and horizontal flip, and writes the edited image back to disk.
Learning Objectives
- Parse the PPM header and pixel data from a binary file stream
- Model an image as a class wrapping a std::vector of RGB pixels
- Index into the pixel buffer with row and column arithmetic
- Implement point filters such as grayscale and colour inversion
- Implement a convolution filter such as a box blur over a kernel
- Encapsulate image operations behind clean member functions
- Write valid PPM output with std::ofstream in binary mode
