achieve

According to the above article in the simple two-dimensional code generation, now adjust the layout.

Drag a button, double-click it to enter the event.

Private  void button6_Click ( Object SENDER, EventArgs E) 
        { 
            // dimensional code content object 
            AssetEntity assetEntity = new new AssetEntity () {the Name = " handed " , Gender = " M " , the Url = " 123 " };
             // generated using the above the method of two-dimensional code to obtain two-dimensional code bitmap objects 
            Bitmap bitmap = ZxingHelper.CreateQRCode ( " high-handed " );
             // re-drawn two-dimensional code layout 
            Image img = ZxingHelper.GetPrintPicture (bitmap, assetEntity, 400 , 400);
             // set the picture source pictureBox 
            the this .pictureBox1.Image = IMG; 
        }

 

Here a new tool class ZxingHelper, which calls the method returns CreateQRCode Bitmap format to generate two-dimensional code, and then call its

GetPrintPicture get adjusted layout photos.

Prior to this, first create a new print content storage entity class AssetEntity

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace NPOITest
{
    class AssetEntity
    {
        private string name;
        private string gender;
        private string url;

        public string Name { get => name; set => name = value; }
        public string Gender { get => gender; set => gender = value; }
        public string Url { get => url; set => url = value; }
    }
}

 

Then in Tools

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Drawing.Printing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ZXing;
using ZXing.Common;
using ZXing.QrCode;

            BarcodeWriter writer = new BarcodeWriter();
            writer.Format = BarcodeFormat.QR_CODE;
            writer.Options = options;
            return writer.Write (Asset); 
        }
