I want to convert RGB image to hsv using method in c#, but i still can't do that.
I made a search but found nothing useful. I need a source code for that method. Any help will be appreciated. Thanks.

I tried this

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

namespace tes_skripsi
{
    public partial class Form1 : Form
    {
        Image File;

        public Bitmap Temp;
        public Bitmap warna;


        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

       
        
        private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog f = new OpenFileDialog();
            f.Filter = "(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
            if (f.ShowDialog() == DialogResult.OK)
            {
                File = Image.FromFile(f.FileName);
                pictureBox1.Image = File;
                //Temp = (Bitmap)File;
            }
        }
            

        
       

        private void button2_Click(object sender, EventArgs e)
        {
            Bitmap Temp = new Bitmap(File);
            warna = HSVColor(Temp);
            pictureBox2.Image = warna;

        }

       

        private void HSVColor()
        {
            //pictureBox2.Image = pictureBox1.Image;
            Bitmap con = (Bitmap)pictureBox1.Image;
            int width = con.Size.Width;
            int height = con.Size.Height;
            double hue, saturation, value;
            
            for (int j = 0; j < height; j++)
            {
                for (int i = 0; i < width; i++)
                {
                    Color col;
                    col = con.GetPixel(i, j);
                    //normalisasi RGB
                    con.SetPixel(i, j, Color.FromArgb((col.R) / 255, (col.G) / 255, (col.B) / 255));
                    //rgbtohsv
                    int max = Math.Max(col.R, Math.Max(col.G, col.B));
                    int min = Math.Min(col.R, Math.Min(col.G, col.B));
                    hue = col.GetHue();
                    saturation = (max == 0) ? 0 : 1d - (1d * min / max);
                    value = max / 255d;

                }

            }
        }
