如何将图像徽标放入生成的二维码中 [英] How to put image logo within generated qr code

问题描述

我使Windows应用程序生成c#qr代码

I make windows application to generate c# qr code 

我成功做到了，但我需要将图像放在生成的条形码的中心

I success to do that but i need to put image in center of generated bar code 

但是这实际上是我的问题吗?

我在Visual Studio 2015 Windows窗体应用程序中工作

我使用messagetoolkitqrcode

我的代码是由c#生成的qr代码，如下所示:

private void button1_Click(object sender, EventArgs e)
        {
            using (SaveFileDialog sv = new SaveFileDialog() { Filter = "JPEG|*.jpg", ValidateNames = true })
            {
                if (sv.ShowDialog()==DialogResult.OK)
                {
                    MessagingToolkit.QRCode.Codec.QRCodeEncoder encoder = new MessagingToolkit.QRCode.Codec.QRCodeEncoder();
                    encoder.QRCodeScale = 8;
                    Bitmap bmp = encoder.Encode(textBox1.Text);
                    pictureBox1.Image = bmp;
                    bmp.Save(sv.FileName, ImageFormat.Jpeg);
                }

            }
                
                    
        }

推荐答案

Wiki 对此进行了解释，这是通过纠错实现的.

The wiki has explanation on this as made possible by error correction.

只要您看到的纠错能力高于恢复图像所覆盖信息所需的级别，就应该毫无问题地对QR码进行解码.

As long as you see the error correction capability higher than the level needed to recover the information covered by the image, the QR code should be decoded without problem.
