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.

Technical Details

• Language: C#
• 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, MouseMove, and MouseUp events are used for drawing actions.
• Brush Settings: Allows changing color and pen width dynamically.
• Save Feature: Exports the drawing as an image file using Bitmap and SaveFileDialog.

How to Run

1. Clone the repository:

   git clone https://github.com/AmirAbdollahi/paint.git

2. Open the solution file (Paint.sln) in Visual Studio.

3. Build and run the project.

Motivation

This was a self-challenge project during my early days of learning C#. I wanted to explore how to handle graphics, user input, and WinForms events. It helped me gain a deeper understanding of Windows desktop development and UI rendering.

What I Learned

• Drawing on Graphics objects
• Managing user interactions like mouse movements
• Handling UI components and events in WinForms
• Basics of color and shape manipulation in a GUI

Acknowledgments

Inspired by the classic Microsoft Paint and my curiosity about how drawing tools work behind the scenes.
