Graphics in C#

We will learn some graphics processing using the C# Express. We will be working with Graphics Files. In this tutorial we will see, how to create a new png file of a given size and then write a line from one given coordinate to another coordinate. So here is the program. 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            using (Bitmap b = new Bitmap(640, 480))
            {
                using (Graphics g = Graphics.FromImage(b))
                {
                    g.Clear(Color.White);
					g.DrawLine(Pens.Red, 10, 10, 100, 100);

                }
                
                b.Save(@"C:\tutorials\blank_640_480.png");
            }
        }
    }
}



Some Explanation 

Bitmap b= Bitmap(640, 480)
Initializes a new instance of the Bitmap class with the 640x480 and assigns it to variable b.

Graphics.FromImage Method Creates a new Graphics from the specified Image b. 
 g.Clear(Color.White);

Creates a white background. 

 g.DrawLine(Pens.Red, 10, 10, 100, 100);


Draws a line in Red color from Coordinate (10,10) to (100,100)

and Finally 

 
b.Save(@"C:\tutorials\blank_640_480.png");


saves the file image as blank_640_480.png in the directory C:\tutorials
