Paint Application (C#)

Welcome to my Paint application — one of the first major challenges I tackled when I started learning C#. This project holds a special place in my journey as a developer, and it's a fun attempt to simulate the basic functionality of the classic MS Paint application.

Features

• Draw lines, rectangles, ellipses, and freehand shapes
• Change pen color and thickness
• Fill shapes with colors
• Erase content
• Clear canvas
• Save your drawing

Project Goals

The main goal of this project was to simulate the basic functionalities of the classic Microsoft Paint application using C# and WinForms. The focus was on learning graphical programming concepts, handling user inputs, and building an interactive desktop UI. It served as a hands-on project to understand:

• Event-driven programming
• Drawing graphics on a canvas
• Real-time mouse interaction
• Building user-friendly interfaces

Architecture Overview

The project follows a simple structure, designed for learning and experimentation rather than scalability. Here's an overview of how it's built:

• Windows Forms (WinForms): Used for the UI and drawing surface.
• Main Form (UI Layer): Contains buttons, color selectors, and the drawing canvas.
• Drawing Logic: Handles mouse events (Down, Move, Up) to draw on the canvas using the Graphics object.
• State Management: Keeps track of selected tool, color, brush size, and drawing mode.

• Framework: .NET Framework (WinForms)
• Drawing Surface: PictureBox or a custom panel used to handle drawing.
• Rendering: Uses Graphics class for shapes and freehand lines.
• Mouse Events: MouseDown, , and events are used for drawing actions.
