PGM Image Editor

This project implements a PGM (Portable Gray Map) image editor in C++ using 2D arrays. The editor allows users to perform various operations on PGM images, including flipping, brightness adjustment, and finding image negatives.

Features

  • Load and Save PGM Images: Load PGM images from files and save the edited images to new files.
  • Flip Images: Flip images vertically or horizontally.
  • Change Brightness: Increase or decrease the brightness of images.
  • Negative Images: Create negative versions of images.
  • Combine Two Images: Combine two images side by side.
  • Median Filter: Apply a median filter to remove noise from images.
  • Custom Filter: Apply a custom filter to images (bonus feature).

Usage

  1. Clone the Repository:

    git clone https://github.com/yourusername/pgm-image-editor.git
cd pgm-image-editor

  2. Compile the Program: Compile the source code using a C++ compiler:

g++ -o pgmEditor main.cpp pgmEditor.cpp
  1. Run the program
./pgmEditor
  1. Follow the On-Screen Instructions: The program will prompt you to enter the name of the image file you want to edit. Then, you can choose from various editing options by entering the corresponding number:
  • 1: Combine Two Images Side by Side
  • 2: Change Brightness
  • 3: Find Negative of an Image
  • 4: Flip Image Vertically
  • 5: Flip Image Horizontally
  • 6: Apply Median Filter (Remove Noise)
  • 7: Apply Custom Filter (Bonus)
  • -1: Exit the Program
  1. Requirements

-C++ Compiler

  • Basic knowledge of PGM file format
  1. File Structure
  • main.cpp: Main file containing the program's entry point.
  • pgmEditor.h: Header file for the grayImage class.
  • pgmEditor.cpp: Implementation of the grayImage class methods.
