I write Coloring algorithm FloodFill and that ok's, it's work. I can description it: choose a new point X in your drawings, ex: g.drawrectangle(new pen(Color.Blue), 100,100,200,50) , Asolute, a point X can be: (120,120) or more, more, etc...In addition choose a color you want paint( i choose Violet) and Color of Rectangle'Line: Blue, after all, it will spreading 4 directions and top where's color of line(Blue) So, like:

and code:
Code:
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 FloodFill
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        Bitmap bm;
        Graphics g;
        private bool SameColor(Color c1, Color c2)
        {
            return ((c1.A == c2.A) && (c1.B == c2.B) && (c1.G == c2.G) && (c1.R == c2.R));
        }
        private void tobien1(Bitmap bm, Point p, Color Color, Color LineColor)
        {
            Stack<Point> S = new Stack<Point>();
            S.Push(p);
            while (S.Count != 0)
            {
                p = S.Pop();
                Color CurrentColor =  bm.GetPixel(p.X, p.Y);
                if (!SameColor(CurrentColor, Color) && !SameColor(CurrentColor, LineColor))
                {
                    bm.SetPixel(p.X, p.Y, Color);
                    S.Push(new Point(p.X - 1, p.Y));
                    S.Push(new Point(p.X + 1, p.Y));
                    S.Push(new Point(p.X, p.Y - 1));
                    S.Push(new Point(p.X, p.Y + 1));
                }
            }
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            g = this.CreateGraphics();
        }
        private void DrawRectangle(Bitmap bm, Point p, int width, int height, Color c)
        {
            Graphics g = Graphics.FromImage(bm);
            g.DrawRectangle(new Pen(c), p.X, p.Y, width, height);
        }
        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            bm = new Bitmap(ClientSize.Width, ClientSize.Height);
            DrawRectangle(bm, new Point(100,100), 200, 50, Color.Blue);
            g.DrawImage(bm, new Point(0, 0));
        }
        private void button1_Click(object sender, EventArgs e)
        {
            tobien1(bm, new Point(120,120), Color.Violet, Color.Blue);
            g.DrawImage(bm, new Point(0, 0));
        }
    }
}
It's work, Ok? Now, i want: how can make it slowly, slowy process of spreading 4 directions, my mean: when you press F5 to build, and all what you see: it finished. So, can be make it slowly, slowly??? can be? I want to see spreading 4 directions slow and how it' work. Can you understand and help me? Thanks.
