This project was developed as part of my Electrical Engineering and Information Technology studies, providing practical experience in software development with Qt and image processing.\n\n## Features\n\n- **Load and save images:** Supports common formats like PNG, JPG, and BMP.\n- **Apply filters:** Enhance or modify images with a selection of filters including:\n    - Brightness (with adjustable intensity)\n    - Sepia\n    - Gaussian Blur (with adjustable radius)\n    - Negative\n- **Before/after comparison:** Easily visualize the effects of applied changes.\n- **RGB histograms:** Analyze image color distribution through interactive histograms.\n- **Unit-tested core components:** Ensures reliability and robustness of key functionalities.\n\n## Architecture Overview\n\n- Clean separation between GUI and logic\n- Singleton pattern used for image storage\n- Modular filter classes using polymorphism\n- Dedicated `ImageProcessor` for applying filters\n- Full unit test coverage for core modules\n\n## Technologies Used\n\n- **C++17**\n- **Qt 6**\n- **QImage** for image handling\n- **QCustomPlot** for histogram\n- **QTest** for unit testing\n- **qmake**\n\n## Running Tests and Build Instructions\n\n### Building and Running Tests with Qt Creator (Recommended)\n\n1. Open the file `test_PhotoViewerPro.pro` in **Qt Creator**.\n2. Select an appropriate build kit (e.g., MinGW, MSVC).\n3. Click **Build** to compile the test project.\n4. Click **Run** to execute the tests.\n\n## Build Instructions\n\nUsing Qt Creator:\n\n1. Clone this repo\n2. Open the file `PhotoViewerPro.pro` in **Qt Creator**\n3. Build and run\n\n## License\n\nThis Project is licensed under the MIT License - see LICENSE.md for details.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fero57%2Fqtimageeditor","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fero57%2Fqtimageeditor","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fero57%2Fqtimageeditor/lists"}
