Hi Friend,
 
As I feel, what you have done is correct. If you change the size of the matrix then definetely you will have to reassign the values of each and every pixel. I dont think you can stop that by using another way.
 
You can use a class like this. So you can set the values from outside according to OOP concepts.

 

public class MyImage
{
 private int _ImageSize = 16;
 private double[,] _Matrix;

 public MyImage(int imgsize)
 {
      _ImageSize  = imgsize;
      _Matrix = new double[_ImageSize, _ImageSize];
 }

 
 
 

 public double this[int x, int y]
 {
  get { return _Matrix[x, y]; }
  set { _Matrix[x, y] = value; }
 }
}
