Overview
PaintApp is a project designed to enhance C++ proficiency by developing a drawing application inspired by Microsoft Paint. Created using Qt Creator and the Qt library, this project aimed to explore graphical user interface management, user event handling, and image processing. The application allows users to draw freely on a canvas using various tools like a pencil, brush, and eraser. It also includes advanced features such as shape management (rectangles, circles, lines), color selection through a dynamic palette, stroke thickness adjustment, and layer support. In addition to drawing tools, PaintApp offers file saving and loading, support for common image formats (PNG, JPEG), and an undo/redo feature for greater flexibility.
