Тут создал код,ток он чтото не робит помогите...

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Negative
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Negative(PaintEventArgs e)
        {
            Bitmap myBitmap = new Bitmap(50, 50, PixelFormat.Format32bppArgb);
            Graphics g = Graphics.FromImage(myBitmap);
            g.FillRectangle(new SolidBrush(Color.FromArgb(255, 128, 128, 128)),
                new Rectangle(0, 0, 50, 50));
            myBitmap.Save("123.jpg");
            Image myImage = Image.FromFile("123.jpg");
            e.Graphics.DrawImage(myImage, 20, 20);
            ColorMatrix myColorMatrix = new ColorMatrix();
            // Red
            myColorMatrix.Matrix00 = -1.00f;
            // Green
            myColorMatrix.Matrix11 = -1.00f;
            // Blue
            myColorMatrix.Matrix22 = -1.00f;
            // alpha
            myColorMatrix.Matrix33 = -1.00f;
            // w
            myColorMatrix.Matrix44 = -1.00f;

            ImageAttributes imageAttr = new ImageAttributes();
            imageAttr.SetColorMatrix(myColorMatrix);
            Rectangle rect = new Rectangle(100, 20, 200, 200);
            e.Graphics.DrawImage(myImage, rect, 0, 0, 200, 200,
                GraphicsUnit.Pixel, imageAttr);

        }

    }
}

Правильно не работает... Ты Negative нигде не вызываешь
