Hi.
I have a project which opens an image in PictureBox1, no problem. But the Public Static Color method at the bottom of the code is not working. I was hoping it would display the average value of the pixels in the image. Can anybody help me to understand why it is not working please? Thank you.

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


namespace imageAlign
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Bitmap myImage1 = (Bitmap)pictureBox1.Image;
            OpenFileDialog ofd1 = new OpenFileDialog();
            if (ofd1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                pictureBox1.Image = Image.FromFile(ofd1.FileName);
                Image k = Image.FromFile(ofd1.FileName);
                Graphics g = Graphics.FromImage(k);
                g.FillRectangle(Brushes.White, 155, 235, 120, 70);
                g.DrawRectangle(Pens.YellowGreen, 155, 235, 120, 70);
                StringFormat sf = (StringFormat)StringFormat.GenericTypographic.Clone();
                sf.Alignment = StringAlignment.Center;
                sf.LineAlignment = StringAlignment.Center;

                g.DrawString(DateTime.Now.ToShortDateString(), new
                Font("Arial", 14, GraphicsUnit.Point), Brushes.Black, new RectangleF(157, 237, 114, 65), sf);

                g.Dispose();
                k.Save("C:\\testimage.jpeg", ImageFormat.Jpeg);



                Image image_rect = Image.FromFile("C:\\testimage.jpeg");
                pictureBox3.Image = image_rect;
                //pictureBox3.Height = image_rect.Height;
                //pictureBox3.Width = image_rect.Width;

                k.Dispose();
            }
        }

             public static Color getDominantColor(Bitmap myImage1)
             {
                  //Used for tally
            int i = 0;
            int j = 0;
            int r = 0;
            int g = 0;
            int b = 0;

            int total = 0;

            for (i = 0; i < myImage1.Width; i++)
            {
                for (j = 0; j < myImage1.Height; j++)
                {
                    Color clr = myImage1.GetPixel(i, j);

                    r += clr.R;
                    g += clr.G;
                    b += clr.B;

                    total++;
                }
            }

            //Calculate average
            r /= total;
            g /= total;
            b /= total;

            
            Console.WriteLine(j.ToString() + " " + i.ToString());
            return Color.FromArgb(r, g, b);
            }
    


           
        private void button2_Click(object sender, EventArgs e)
        {
            Bitmap myImage2 = (Bitmap)pictureBox2.Image;
            OpenFileDialog ofd2 = new OpenFileDialog();
            if (ofd2.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                pictureBox2.Image = Image.FromFile(ofd2.FileName);
            }
        }
 
    }

}
