C# Project

Share

In this project we are learning to read and write image in C#

Requirement

For this project we will need Microsoft Visual Studio

Open Visual Studio and create a new project. Select Windows Form Application. Give your project a name. Example: ReadWriteImage.

We will use Bitmap to read and write image.


Bitmap bmp = new Bitmap("D:\\Image\\Taj.jpg");

Form1.cs


using System;
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 ReadWriteImage
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            //read image
            Bitmap bmp = new Bitmap("D:\\Image\\Taj.jpg");

            //load image in picturebox
            pictureBox1.Image = bmp;

            //write image
            bmp.Save("D:\\Image\\Output.png");
        }
    }
}

Form1.Designer.cs


namespace ReadWriteImage
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
