How to create QR code image with company logo [closed]

Answer 1

I created a video showing how to use an open-source c# library to create a QR Code and then upload/embed a logo of your choosing into the QR Code:

The video is only 10 minutes long and the result is a working QR Code generator. In case you don't care to spend the ten minutes, here is the source code:

The front page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="CodeCreator._default" %>





    


    

    

        
        


        
        


        
        


        
    
    

And the code-behind:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using MessagingToolkit.QRCode.Codec;
using MessagingToolkit.QRCode.Codec.Data;
using System.Drawing;
using System.Drawing.Imaging;

namespace CodeCreator
{
    public partial class _default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }

        protected void CreateCode_OnClick(object sender, EventArgs e)
        {
            string path = "c:\\code\\projects\\CodeCreator\\CodeCreator\\";
            QRCodeEncoder encoder = new QRCodeEncoder();

            encoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.H; // 30%
            encoder.QRCodeScale = 10;

            Bitmap img = encoder.Encode(URL.Text);
            LogoUpload.SaveAs(path + LogoUpload.FileName);

            System.Drawing.Image logo = System.Drawing.Image.FromFile(path + LogoUpload.FileName);

            int left = (img.Width / 2) - (logo.Width / 2);
            int top = (img.Height / 2) - (logo.Height / 2);

            Graphics g = Graphics.FromImage(img);

            g.DrawImage(logo, new Point(left, top));

            img.Save(path + "img.jpg", ImageFormat.Jpeg);

            QRImage.ImageUrl = "img.jpg";
        }
    }
}
