將兩個圖像添加到一個圖像c＃？

Question

我想結合兩個圖像，但我不能成功。請幫幫我。

當嘗試組合PictureBox只顯示第一個圖像，但沒有第二個圖像，當我刪除第一個圖像時，我可以看到第二個圖像。

此外，我試圖設置第一個圖像，並在圖像上繪製文本也不工作。請幫忙。

Image myimg = Code128Rendering.MakeBarcodeImage(textBox1.Text, 2, true); 

Bitmap image = new Bitmap(myimg.Width + 20, myimg.Height + 50); 
pictureBox1.DrawToBitmap(image, new Rectangle(0, 0, myimg.Width + 20, myimg.Height + 50)); 
Bitmap bmp = new Bitmap(myimg.Width + 20, myimg.Height); 
Bitmap bmp2 = new Bitmap(myimg.Width + 20, 20); 
Graphics Cizgi2 = Graphics.FromImage(bmp2); 
Graphics Cizgi = Graphics.FromImage(bmp); 
Cizgi.DrawImage(myimg, 0, 0); 

FontStyle sitil = FontStyle.Bold; 
Font fonts = new Font(new FontFamily("Arial"), 10, sitil); 
Cizgi2.DrawString(textBox1.Text, fonts, Brushes.Black, 5, myimg.Height + 10); 

Graphics g = Graphics.FromImage(image); 
g.DrawImage(bmp, new Point(10, 0)); 
g.DrawImage(bmp2, new Point(0, bmp.Height + 10));

I want to image seems like first but i cant make

它看起來像你試圖垂直連接兩個圖像？實際上這很簡單，你可以看這裏（C# image concatenation），但我也修改它以滿足你的需求。我想，這應該工作：

 float drawBorderX = 5; 
     float drawBorderY = 5; 

     //Set up our two images 
     Bitmap barCode = Code128Rendering.MakeBarcodeImage(textBox1.Text, 2, true); 
     Bitmap text = new Bitmap(barCode.Width, 50); 
     Graphics textGraphics = Graphics.FromImage(text); 


     //Draw the text to the bottom image. 
     FontStyle sitil = FontStyle.Bold; 
     Font fonts = new Font(new FontFamily("Arial"), 10, sitil); 
     textGraphics.FillRectangle(new SolidBrush(Color.White), new Rectangle(0, 0, text.Width, text.Height)); 
     textGraphics.DrawString(textBox1.Text, fonts, Brushes.Black, drawBorderX, drawBorderY); 

     //Vertically concatenate the two images. 
     Bitmap resultImage = new Bitmap(Math.Max(barCode.Width, text.Width), barCode.Height + text.Height); 
     Graphics g = Graphics.FromImage(resultImage); 
     g.DrawImage(barCode, 0, 0); 
     g.DrawImage(text, 0, barCode.Height); 

編輯：請注意，resultImage將包含你想要的形象，所以你可以設置你的PictureBox是在年底的形象。
