Photo Editor Project README

Introduction

Welcome to the README file for our Qt C++ photo editor project! This document provides detailed instructions on setting up and running the code, including the tools and their versions used. Additionally, it lists all the implemented filters, with explanations for any new filters developed.

Setup and Usage

Prerequisites

• Qt (Version Qt6 6.7.0)
• C++ Compiler (Version 6_7_0_MinGW_64_bit)

Installation

1. Open the Project in Qt Creator: Launch Qt Creator and open your project by selecting the project file (usually a .pro file) from the file browser.
2. Configure Build Settings: Once the project is open, configure the build settings according to your requirements. This includes selecting the build kit (compiler and Qt version) and configuring any additional build steps.
3. Build the Project: Click on the build button (usually a green play button) or select Build > Build Project from the menu to compile the project. This step generates the executable file.
4. Run the Project: After a successful build, click on the run button (usually a green arrow) or select Build > Run from the menu to execute the compiled program. This launches the application in the Qt Creator's integrated environment.
5. Test the Application: Once the application is running, test its functionality to ensure that it behaves as expected.
6. Deploy or Distribute (Optional): If you intend to distribute the application, you may need to package it for deployment. Qt provides tools for deploying applications on various platforms, including compiling the project statically or dynamically linking required libraries.
7. External Execution: If you prefer to run the application outside of Qt Creator, navigate to the directory where the executable is located and run it directly by double-clicking on it or executing it from the command line.

12. Filter 12: Rotate
13. Filter 13: Darken and Lighten Image
14. Filter 14: Adding a Frame to the Picture
15. Filter 15: Detect Image Edges
16. Filter 16: Blur Images
17. Filter 17: Sunlight
18. Filter 18: Oil painting Effect

Explanation of New Filters

1. Filter 1: Hue shift

   • Take Image and Hue shift
   • Take Image Pixels' RGB and convert it to HSV
   • Add Hue shift to HSV
   • Turn new HSV to RGB
   • Set color to the new RGB

2. Filter 2: Pixelate

   • Take old Image and Pixelate intensity
   • Make new image of size (Image / Pixelate intensity)
   • Set every pixel of new image with the average of every pixel's RGB with area of (Pixelate intensity)^2
